National Sentiment Reflected on Colour of Clothing

Jo Nov 16, 2022

Not only the style and pattern but also the colour of clothing represent features of times and national sentiments. The colours of the traditional clothing of our nation fully display the lofty and pure sentiments of our nation. Our nation preferred white or light soft vivid colours to strong colours for primary colours of their clothing. From olden times, our nation worshipped white and usually chose white for their clothing. Therefore, our nation has been called “white-clad race” or “white-clad folk”.

In addition to white, many bright colours like light yellow, light pink or light green were also popular. With light soft colours instead of harsh strong ones, our people managed to produce a good harmony of colours, adorning Korean clothes to look more beautiful. Since Korean clothes are usually in two pieces, upper and lower garments in harmony of colours give fresh feelings and beauty. Making the most use of such advantage, our people added as much beauty as possible to the Korean clothes with a colourful harmony of two pieces as in “green jacket and crimson skirt” or “yellow jacket and crimson skirt”. Korean people further raised the ornamental effect of Korean clothes by making their small parts such as gussets, collars, cuffs, coat strings, etc. different in colours from the main part. This combination of colours demonstrated the great aesthetic sense of our nation whereby they could get maximum effect by making effective use of visual aspects of the harmony of only a few colours.

The colours of the Korean clothing reflective of the aesthetic sense and feelings of the Koreans, who created bright and soft beauty, are still in wide use. Our clothes are undergoing development as unique, graceful and elegant ones full of the flavor and fragrance of our nation only.

Law of Ratio 1:10:100 and Quality Management

Jo Nov 15, 2022

There may be potential flaws in the whole process of quality formation. The time and expenditure for their control are different according to when they are detected.

Many people found one famous principle while they were summing up their quality management. That is the Law of Ratio 1:10:100.

It means that it takes an hour and 1 won to manage a flaw of quality at the stage of development and design, 10 hours and 10 won at the stage of production, and 100 hours and 100 won at the stage of marketing. That is to say, plan: production: marketing = 1:10:100.

Kang In Song, an institute head at the Faculty of Management of Industrial Economy, has formulated 6 types related to the time of flaw detection and rectification and analyzed the influences of each type on customer satisfaction, time and cost.

Type 1-4: stages of development and design, design examination, production, and test, respectively. In each stage, quality flaws are found and controlled.

Type 5 and 6: stages when quality flaws have been transferred to customers. Type 5 gives priority to troubleshooting and maintenance and also employs refund or exchange of goods. Type 6 is when quality flaws transferred to customers cannot be controlled by enterprises.

Enterprises can choose one of these types to manage quality flaws.

The effects on customer satisfaction, time and cost are:

The enterprise which agrees to Type 1 might make the best choice by giving great satisfaction to the customers and ensuring minimum time and cost. It guarantees preventive management of quality. This enterprise can be said to have quality management level of 6σ.

Any enterprise in favor of Type 2 may give basic satisfaction to the customers and control flaws with comparatively short time and low cost. It has quality management level of 5σ. Its drawback is relative – it is not preventive but has pursuit property and delays the time of starting production.

An enterprise whose quality management goal is Type 3 may have the following advantages. It is preventive and gives partial satisfaction to the demand of the customers. It might ensure production and supply in good time and save a lot of money for equal and continuous improvement even if it needs 10 times as much expenditure. It might have quality management level of 4σ.

An enterprise in favor of Type 4 may not have good points by and large but flaws are not transferred to the customers. It might have quality management level of 3σ. It is not preventive but has pursuit property. It does not satisfy customers’ requirement but ask them for its quality level. It might delay supply and need 10 times its expenditure, in particular in the last stage.

The enterprise in Type 5 might not have good points but if any, it is responsible for flaws and takes measures even though they have already been transferred to the customers. It has quality management level of 2σ. It might always deal with the customers to fix exchange or refund the goods. It has a problem of whom to allocate extra pay – the enterprise or the customers. It might need time for fixing and servicemen and equipment for it.

Any enterprise in Type 6 may have decreased income and legal problems. It might injure its reputation, causing a lot of loss and hardly managing its own business, as flaws are transferred to customers, which makes them disappointed. It is on the verge of bankruptcy. Its quality management level is 1σ.

The 6 types mentioned above let us aware of different effects on customer’s satisfaction, time and cost.

Pyongyang Speciality ― Kamhong-ro

Jo Nov 13, 2022

Kamhong-ro, one of the three old famous spirits well known across the country which has developed centered in Pyongyang over a long period of time, is a valuable traditional inheritance of our nation.

Our country has a very long history of making and drinking liquor, but records of reddish sweet Kamhong-ro finally began during the feudal Joson dynasty. “Kyongdo Magazine” and “Pyongyangji” compiled in this period wrote that Pyongyang Kamhong-ro was famous. “Rimwonsipryukji” published at the beginning of the 19th century described the way of making Kwanso Kamhong-ro, according to which the bottom of the pot for dewdrops was plastered with honey and they were mixed with gromwell. It wrote that it was the best of all kinds of liquor as it was sweet and strong and it looked red like a lipstick. The term Kamhong-ro means a sweet (kam) reddish (hong) spirit (ro).

Until the 19th century, fermented liquid prepared from traditional Korean malt was distilled three times and it was mixed with gromwell and honey to make sweet red Kamhong-ro, high-quality medicinal liquor. In old times our people came to find medicinal herbs good for health and longevity in the course of conquering the nature and paving the way for their life and they actively introduced them to their life to make herbal tonics, which have still been conveyed down to the present day. Kamhong-ro, too, has been accepted as healthful medicinal drink and one of the three old famous spirits. Right amount of medicinal spirits helped our people to protect health and they were served on important days like family events or holidays.

Chairman Kim Jong Il said in his early years that our country has many famous spirits, among which Inphung Liquor, Kaesong Insam Liquor, Blueberry Liquor and Kamhong-ro had been numbered as the best since olden times in our country, and that it is a good idea to provide our people with famous liquor.

Today Kamhong-ro, which adds our national flavor and native savour, is served in public service facilities for people, giving our people national pride and delight.

Experiences Gained in Enhancing Students’ Applicati...

Jo Nov 10, 2022

“Computer Application in Major Field” is a subject that studies the ways of using applications for the simulation and analysis of scientific and technological calculations in the field of materials engineering and hydrodynamical processes in hydrometallurgy.

In the past, teachers had some problems with stimulating students’ thinking for developing their creativity and raising their program application abilities.

Therefore, Kim Chol Nam, a researcher at the Faculty of Metal Engineering, has introduced problem-based learning (PBL) whereby students could seek discussion points and solutions to them on their own, in order to enhance their application abilities of simulating and analyzing hydrodynamic problems arising in process operations.

First, while he was explaining the principle of the process by using a virtual reality system, he led them to discovering problems and finding solutions from FLUENT library. It was helpful for students to have a full understanding of the hydrodynamic principles of hydrometallurgy.

After they studied the hydrodynamic quantities for turbulent kinetic energy in FLUENT library, he taught them the method of determining the agitation characteristics so that they could have a technical and hydrodynamic notion of hydrometallurgy. In a word, he emphasized that the agitating condition was an important factor in the chemical reactions made in a leacher with air agitation and the quantity was turbulent kinetic energy and that it could be calculated simply in FLUENT. As a result, they became more enthusiastic in their study with confidence that they could solve any hydrodynamic problems by utilizing applications.

Second, he designed his teaching plan in a way that students could be familiar with how to simulate and analyze the process through an understanding of the process, a determination of its factors, an analysis and a determination of reasonable parameters, and raise their application ability, all by introducing PBL.

It is the basic purpose of PBL to raise the ability of application and self-study by making the discovery of questions and solving them a process of inquiry and cooperation.

With a good understanding of the chemical reaction process in the leacher with air agitation through the virtual reality system, the students raised by themselves several questions like improving the agitating condition, an important factor that affects reaction rates, that is, the relative position between the circulating pipe and the air inlet and the ratio of the diameter of the inlet and the circulating pipe to the diameter of the leacher body. While finding ways to solve them, they were able to raise their ability of application and self-study.

First National Letters ― Sinji Letters

Jo Nov 8, 2022

Sinji letters are the first national letters made after several stages of letter life as a result of a long time of thinking and painstaking inquiry of the ancient Korean people who created their own language Korean to use as a powerful weapon for struggle and creation in the remote past.

Sinji letters were invented by a man called Sin Ji in Ancient Korea. The word sinji meant a big man, so it usually referred to a ruler, a master or a boss. In the historical records, the word sinji is written in several Chinese characters ―神誌 (sinji), 神志(sinji), 巨智(koji), etc. ― which have no connections with the meanings of each character but are of the same sound as the native Korean word sinji. Sinji letters are also recorded as wangmun (王文), which means that they were used by rulers including kings. It reflects the social and historical characteristics of the past societies like a slave society where the ruling classes used to hog letters, and at the same time it has some connections with the meaning of the name “sinji letters”.

Historical books “Kyuwonsahwa” and “Pyongyangji” have some records associated with sinji letters. In later national classics “Haedongryoktaemyonggaphilbo” and “Nyongbyonji” are recorded sixteen of the sinji letters of Ancient Korea, which became widely known to the world. Due to the lack of the remaining data, things like the number and system of the sinji letters, sound values of each letter and norm of use have not been fully illuminated yet. However, it is clear from the form of the letters that they were phonetic and syllabic letters and they were written downwards. The fact that similar letters are engraved on several archaeological relics such as earthenware of Ancient Korea and blocks of Rangnang old tombs proves that sinji letters were widely used in Ancient Korea.

In conclusion, sinji letters convincingly demonstrate that the Korean nation is a resourceful nation that created their independent national letters as early as in ancient times and developed their own unique civilization on the basis of them.
