In early 1956, MSG (monosodium glutamate) had been produced by hydrolysis of the vegetable proteins in Korea. In accordance with development of fermentation technology mainly led by the Japanese scientists, its major production method has been changed to microbial fermentation since 1962. Meanwhile, 5'-ribonucleotides which are nucleic acid-related condiments have been produced by the enzymic hydrolysis of yeast RNA and/or the direct fermentation by Miwon Co. and Cheil sugar Co., respectively since 1977. At the technological viewpoints, Korean fermentation level seems relatively highly-reputated over the world in terms of production yield and unit-consumption level. For further progress of technology, our emphasis on this research area should be laid on both improvement of bacterial strain by means of modern biotechnology and process development through the immobilization and/or computerized control technics, etc.

In the Joseon dynasty one in seven houses enjoyed their home-brewed alcoholic beverages, which lead to the development of a variety of Korean traditional liquors throughout the country. However, when Korea was under Japanese rule, Korean traditional alcoholic beverages disappeared during this period. Since the 1980s, the Korean government has tried to revitalize the traditional alcoholic drinks unique to Korean culture and taste. Nevertheless, the development of traditional liquors is subjected to many constraints due to current market demand and liquor laws. To address this, we propose some suggestions that should be implemented ahead. First, it is necessary to revise the term traditional liquor including makgeolli as 'Korean sool' to expand the market size. Secondly, the use of koji and excellent yeast isolated from nuruk should be scientifically modernized. Lastly, the government should establish the National Korean Sool Research Institute. These practices will contribute to the succession of Korean liquor and its globalization.

Parentage tests using polymorphic DNA marker are commonly performed to avoid incorrect recording of the parental information of livestock animals, and single-nucleotide polymorphisms (SNPs) are becoming the method of choice. In Japanese Black cattle, parentage tests based on the exclusion method using microsatellite markers are currently conducted; however, an alternative SNP system aimed at parentage tests has recently been developed. In the present study, two types of simulations were conducted using the pedigree data of two subpopulations in the breed (subpopulations of Hyogo and Shimane prefectures) in order to examine the effect of actual genetic and breeding structures. The first simulation (simulation 1) investigated the usefulness of SNPs for excluding a close relative of the true sire; the second one (simulation 2) investigated the accuracy of sire identification tests for multiple full-sib putative sires by a combined method of exclusion and paternity assignment based on the LOD score. The success rates of excluding a single fullsib and sire of the true sires were, respectively, 0.9915 and 0.9852 in Hyogo and 0.9848 and 0.9852 in Shimane, when 50 SNPs with minor allele frequency (MAF: q) of 0.25${\leq}$q${\leq}$0.35 were used in simulation 1. The success rates of sire identification tests based solely on the exclusion method were relatively low in simulation 2. However, assuming that 50 SNPs with MAF of 0.25${\leq}$q${\leq}$0.35 or 0.45${\leq}$q${\leq}$0.5 were available, the total success rates including achievements due to paternity assignment were, respectively, 0.9430 and 0.9681 in Hyogo and 0.8999 and 0.9399 for Shimane, even when each true sire was assumed to compete with 50 full-sibs.

This study was performed to investigate shopping behavior of Chinese, Japanese, and US tourists in Korea. For this purpose, travel activities and shopping items were identified first. And thereafter the shopping satisfaction, travel satisfaction, intention to word-of-mouth, and intention to re-visit were compared by country, gender and age. Finally, the effect of shopping satisfaction on travel evaluations as well as the effect of demographics on shopping satisfaction were examined. Secondary data were used for this survey, while ${\chi}^2$ test, t-test, ANOVA, Duncan test and regression analysis were applied to analyze data. The results were listed below. First, main travel activities were shopping, followed by enjoying natural scenery and visiting historic sites. Apparel, cosmetics, leather goods, and shoes were major shopping products. Chinese and Japanese tourists preferred cosmetics and apparel most, while US travellers bought lots of apparel and shoes. Men and older tourists tended to buy food products more than women and younger people did. Second, degree of shopping satisfaction significantly differed by country and age. The US tourists showed highest satisfaction, followed by Japanese and Chinese ones. Younger people tended to be satisfied more than older people significantly. In terms of travel satisfaction and intention for word-of-mouth, the US tourists, women, and younger people revealed higher scores than the other counterparts. Intention to re-visit Korea were significantly different, based on country and gender, showing higher for the US people and women. Third, shopping satisfaction was found to affect travel satisfaction, intention for word-of- mouth, and intention to revisit Korea significantly. In turn, travel satisfaction was also shown significantly to affect on intention for word-of-mouth, and intention to re-visit Korea.

This thesis is a study on the change and the process of the development of the hygiene administration during the period of modernization of our nation which promoted by the open door policy of our country chiefly under the pressure of the foreign countries. During that period Korea had reorganized the old political system radically and introduced the western medical system. Through the close study of literature concerning the system of the hygiene administration, the laws of health and hygiene, the environmental sanitation organizations and their practical activities the author obtained the conclusions as following 1. The government passed around 40 laws of health and hygiene from the time when the bureau of hygiene was founded in 1894 to the annex of Korea to Japan. Most of the laws were believed to be established by the enforecement of Japanese government. When the epidemics were prevailing, a decree for the prevention of the epidemics was proclaimed by the Japanese president of the headquarters of national police. It is shown well that the sovereignty of Korea had been deprived. 2. After the armex of Korea to Japan, the hygiene police and the general police belonging to the bureau of national police shared the tasks of health and hygiene. This was a temporary system which had existed just during the colonial period. As for the water-supply which is the most important facility among the various environmental hygiene facilities, the rate of supply was remarkably high in Japanese rather than in Korean. 3. During the period of American military administration, it is notable that the division of hygiene in the bureau of national police was replaced by the bureau of hygiene. This period is regarded as the turning point when hygiene administration was operated by means of education along with the introuction of American system of public health. 4. Ever since the foundation of the republic government, the laws of health and hygiene which had been established during the colonial period have been put into operation without rriuch change except several regulations concerning food.

일제강점기 황해에서 일본 포경회사에 포획된 대형 수염고래류는 참고래 3,173마리, 대왕고래 7마리, 혹등고래 28마리를 합하여 총 3,200마리 이상이 포획되었다. 이러한 대량포획으로 황해에서 대형 수염고래류가 거의 소멸되었다. 황해는 대형 수염고래류가 서식하기에 적합한 수온조건($4{\sim}26^{\circ}C$)과 풍부한 먹이 조건을 갖추고 있어 동계와 춘계에 대형 수염고래류의 출현이 많았던 것으로 추정된다. 동계와 춘계에 참고래가 많이 포획된 것은 이들의 주 먹이인 태평양크릴새우(Euphausia pacifica)가 표, 중층에 많아 이들이 이 시기에 대량 회유한 것에 기인된다. 그러나 수온약층이 강하게 형성되는 여름과 가을에는 태평양크릴새우가 수온약층 아래에 분포하여 포식 조건이 좋은 다른 해역(울산 해역)으로 이동한 것으로 보인다.

Determination of weekly and daily energy expenditure was made on 62 Republic of Korea Army cadets who were selected at random in order to estimate the weekly and daily ealorie expenditure. Basal metabolic rate (B.M.R.), and energy cost of various military and daily activities were measured by indirect calorimetry using open circuit method. Time-motion studies were also carried on using a stop-watch. The total weekly energy expenditure was calculated by summation of data using energy cost per minute, and the time spent on each activity. Determination of daily energy expenditure was deduced from each data of weekly energy expenditure. Food survey was also carried on for a week, and daily calorie intake was determined by a weekly average discounting loss in cooking. All measurements were determined from the Standard Table of Food Composition published by the Ministry of National Defense (1961). Following data were observed. 1. Physical status of cadets are as follows. Please note that the height and weight averages are 1-2cm and 4-5kg respectively over that of the Seoul National University students. First year Height 167.92 cm $(S.D.{\pm}4.09)$ Weight 61.72 kg $(S.D.{\pm}4.53)$ Second year Height 167.89 cm $(S.D.{\pm}3.46)$ Weight 63.01 kg $(S.D.{\pm}4.61)$ Third year Height 168.15 cm $(S.D.{\pm}4.24)$ Weight 43.48 kg $(S.D.{\pm}5.03)$ Fourth year Height 168.10 cm $(S.D.{\pm}3.70)$ Weight 64.02kg $(S.D.{\pm}5.10)$ 2. The B.M.R. of cadets averaged $36.57\;Cal./m^2/hr.(S.D.{\pm}3.63\;Cal./m^2/hr.)$ is almost equal with data on the same ages of civilians and the Japanese, but a lower average of $5.1\;Cal./m^2/hr.$ than that of a common soldier. 3. The energy expenditure during various military activities is close agreement with Consolazio. Passmore and Durnin, and Japanese reports.

한국 전통약주와 기존에 암세포주에 대한 세포독성이 보고되어 있는 알코올 음료에 대한 항종양 세포독성을 비교하기 위하여 무증자 발효 방법으로 발효시키면서 한약재를 첨가한 전통약주I과 뽕잎, 메밀 등을 첨가한 전통약주II, 비교 시료로 적포도주, 백포도주, 맥주, 일본 청주 등에 대하여 연구하였다. 각 시료에 대하여 10-80배까지 단계적으로 희석하여 DLD-1, HepG2, K562, EMT6, LLC1에 처리하였을 때, 인체유래 대장암 세포주인 DLD-1의 경우 적포도주에서만 강한 세포독성이 확인되었는데, 전통약주I의 경우 그 농축액에서 DLD-1에 대하여 적포도주와 유사한 세포독성을 확인할 수 있었다. 나머지 4종의 암세포주에서는 10-20배 희석배수에서 적포도주, 전통약주I, 전통약주II가 세포독성을 보였으나, 각 암세포주의 종류에 따라서 세포독성은 약간씩 차이를 보였다. HepG2, K562, EMT6의 경우 10배 희석배수에서 모두 비슷한 세포독성을 보인 반면에 마우스 유래 폐암세포주인 LLC1의 경우에는 전통약주I과 전통약주II의 세포독성이 적포도주보다 우수한 것을 확인하였다. 본 연구의 결과에 의하면 이러한 항암효과는 전통약주에 존재하는 미지의 약리성분이 작용하는 것으로 판단되었다.
