The purpose of this study was to examine the costume worn by women in daily life according to life scenes depicted in genre paintings of the late Chosan Dynasty. The sentiments and customs of the time were examined to discover how costume culture followed women's lifestyles in the late period of the Chosun Dynasty. First, according to life scenes, a field amusement type costume was the most common garment and a commercial activity type costume was the least common garment. Second, when the form of costume was examined followed by the lifestyle it depicted, the following observations were noted. Women depicted in a housework type lifestyle often wore a Minjeogori. In contrast, women appearing in a labor production type or a commercial activity type lifestyle often wore a Banhoijangjeogori with the width of the coat narrowing gradually according to the trends of the time. In the forms of Chima, the women wore a Duluchima and a Gudlchima for convenience during their work and covered a Haengjuchima over it. Third, women shown in a field amusement type, a home enjoyment type or an affection pursuit type lifestyle mainly wore a deep blue colored Chima and Hoijang or Banhoijang Jeogori. While most of the women depicted in a labor production type, a housework type or a commercial activity type lifestyle wore a natural cotton colored Jeogori and a natural cotton colored and light indigo Chima. Fourth, in the field amusement type and the affection pursuit type lifestyle, the wearing of a headdress during outings of women appeared variously influenced by the strengthening restrictions placed on the women's lives according to the ethics of Confucianism.

This thesis mainly studies the Commercial Mediation System in China and its Implications to Korea. Commercial mediation is an important dispute settlement method, however there are more studies on the issues of arbitration than the ones on mediation. Commercial mediation emerges From the tide of economic activity, needing an earnest research and to be developed. Business mediation law has been enacted in some nations like USA, but in Korea, there is no law in mediation field to follow. To set up business mediation law is necessary and urgent as well as feasible. This thesis first introduces the mediation of the general meaning including concept, makes a research concerning the sorts of the mediation, compares the effect of different kinds of mediation, and studies the current status of use of mediation in other countries. Than introduces current status of use of mediation in China, and examine mediation system in China. Through this studies, the writer no that there is almost equal problem in China comparing to Korea. So than examine how Chinese government make countermeasures to cover their problems, and give Korean government several implications that can learn from China.

Teaching ICT skills in extracurricular activity classes of commercial high school helps to bridge the digital divide of the students at the minimum cost, and gives them a chance of getting ICT-related licenses. The purpose of this study is to identify the determinants of satisfaction and planned behavior toward computer classes, offered as extracurricular activities in commercial high schools. A survey methodology was used to investigate a proposed model of influence, and regression analysis was used to analyze the results. The hypothesized model was largely supported by this analysis, and the overall results indicate that the intention to participate in the class is mostly influenced by the expected social effect, individual impact and playfulness from the class. In addition, it was found that the learning environment influences the level of playfulness and social effect, and that the contents quality has some impact on the level of the ease of study and playfulness. Useful suggestions for promoting computer classes as extracurricular activities in commercial high schools are also provided.

As basic research for optimal barley cultivars selection and technical development for quality maintenance, a total of 21 commercial malt products (for making 'Sikhye', a traditional Korean sweet drink) were collected from the Korean market. And then we analyzed the component of the barley malt products as well as conducted comparative analysis on enzyme activity and quality characteristics of the commercial barley malt products. Of the 21 barley malt products, 12 were made from 100 % barley. The result of analyzing general components of barley malts turned out different level of components; moisture 4.91~11.99%, lipid 1.71~2.48%, protein 7.80~11.97%, carbohydrate 73.64~82.24%, total starch 5.50~8.22%, reducing sugar 3.64~14.44%. As a result of measuring enzyme activity of barley malts, there was a wide range of activity difference by the product; diastatic power $36.80{\sim}94.30^{\circ}$, ${\alpha}$-amylase activity 18.17~186.50 unit/g, ${\beta}$-amylase activity 6.53~25.05 unit/g. The results of this study would be used as basic data for optimal cultivars selection to produce barley malts and technical development for quality maintenance.

Some ammonium oxalate soluble pectic fragments prepared from cultured cell wall of Ephycla distrahya elicited the accumulation of p-coumarocylamino acids (p-CAA) in E. distachya cultures while water soluble and alkali soluble fractions had no activity. Partial purification of the pectic fragments fraction using DEAE-cellulose chromatography afforded two active fractions (PS-I and PS-II) which were composed of mainly uronic acids (98-99 w/w %). They elicited the accumulation of p-CAA in an amount of 52-60 nmol per gram fresh weight of cultures. The acidic sugar compositions of PS-I and PS-II were found to be galacturonic acid and glucuronic acid by TLC analysis. They were supposed to act as endogenous elicitors of p-CAA accumulation. In order to investigate the effect of ethylene on p-CAA accumulation, Ethrel, which is known as ethylene generator, and ACC(1-aminocyclopropane-1-carboxylic acid), a direct precusor of ethylene biosynthesis, were added to the culture. However, they did not glycopeptide elicitor [(Con A-II)], either. Consequently, no relationships between ethylene and p-CAA accumulation were recognized. Several tentative elicitors were teted for their activity. Commercial yeast glucan, $CuCl_2$, laminarin and laminariheptaose had slight activity whereas ${\alpha}$-methylmannopyranoside and commercial yeast mannan had no elicitor activity. ${\alpha}$-methylmannopyranoside which has been known as a tentative inhibitor of glucan elicitor in Glycine max did not affect on the elicitor activity of Con A-II.

1. The varietal difference in amylase activity of the digestive fluid of the 5th instar larvae reared on the artificial diet was investigated, using the parent commercial silkworm varieties of Japanese strain. The amylase activity was large different among silkworm varieties. The activity was strong in Hansaeng-1, Jam 115 and Jam 117, medium in Hansaeng-3, Jam 113, Jam 119, and Jam 201, weak in Jam 107, Jam 121 and Gyeongchu. The amylase of the digestive fluid of ten parent commercial silkworm varieties is possible-(ae) type, compared with ＋(＋$\^$ae/) type of Daizo. 2. To investigate the effect of a-amylase pre-treatment of the artificial diet, larvae were fed with the diet treated by a-amylase during 4th-5th instar periods. The blood sugar content and cocoon qualities were slightly higher in the experimental larvae than those in the control, while showing the slight less body weight, amylase activity and dietary efficient.

As all aspects of international activity have kept growing in good transaction, transnational investments, joint ventures, and the licensing of intellectual property, it is inevitable for disputes to increase across national frontiers. International disputes can be settled by arbitration and ADR. In the situation presented in the paper, any dispute shall be finalized by arbitration and conciliation in the Gaeseong Industrial Complex. Inter-Korean Commercial Arbitration in the Gaeseong Industrial Complex has become the principal method of resolving disputes in trade, commerce, and investment in accordance with the "Agreement on South-North Commercial Dispute Settlement Procedures," "Agreement on Organization and Operation of Inter-Korean Commercial Arbitration Committee," and the Annexed Agreement on "Organization and Operation of Inter-Korean Commercial Arbitration Committee" (2013). But the follow-up measures of the said agreements have not been fulfilled. Some prerequisite measures of the Inter-Korean commercial arbitration must be satisfied. In order to proceed with arbitration and conciliation in the Gaeseong Industrial Complex, we need to ask the following: Does the status of an arbitrational matter? Should an agreement to arbitrate contain a choice of law clause? Should one provide for one arbitrator or three? How should the arbitrators be selected? What is the relation between party-appointed arbitrators and the presiding arbitrator (neutral arbitrator)? Do arbitrators compromise more than the litigation? Can conciliation be combined with arbitration? To execute the enactment of arbitration regulations, the contents of the Arbitration Rules of the Korean Commercial Arbitration Board (South) and the Korea International Trade Arbitration Committee (North), together with the Korean Arbitration Act and External Arbitration Act of North Korea and the UNCITRAL Model Arbitration Law and UNCITRAL l Arbitration Rules are reflected in the Rules. There are many aspects of the Inter-Korean Commercial Arbitration. It is essential to understand key elements; namely, the arbitration agreement, appointment of arbitrator, arbitral proceeding and arbitral award, and enforcement and setting aside of arbitral award. This research deals with five chapters. Chapter 1 provides the introduction. Chapter 2 deals with trade volume between South and North Korea and the kinds of dispute in Gaeseong. Chapter 3 addresses contents and follow-up measures of the agreement on the "South-North Commercial Dispute Settlement Procedures," "Agreement on Organization and Operation of Inter-Korean Commercial Arbitration Committee," and the Annexed Agreement on "Organization and Operation of Inter-Korean Commercial Arbitration Committee" (2013). Chapter 4 features the problems and tasks of the pertinent agreements. Chapter 5 gives the conclusion. Enabling parties to find an amicable solution to the dispute in the Gaeseong Industrial Complex can lead to a useful and appropriate framework either through direct negotiation or by resorting to conciliation or mediation in accordance with pertinent agreements and follow-up measures contained in the agreements.
