The Seoul metropolitan government announced an open design competition for reconfiguring the annex building of the National Tax Service Building site on Sejong-daero as a space for citizens to commemorate the 70th anniversary of Korea's liberation. The site, built during the Japanese colonial period, has been in use ever since. This study, as one of the entries for the competition, described the strategy and design contents by drawing the concept and main points of the design through an analysis of the historical context of the site. As the guidelines instructed to consider the value of the Sejong-daero area and the cultural heritage through a comprehensive analysis, this study specified the site as a place connecting the past, present and future. Since the foundation of the Joseon dynasty, the Korean Empire and the Japanese colonial period, Sejong-daero has been a main site for important events and activities along with the change of the city structure. Jungdong, to the rear of the site, was a place for adopting new culture during the beginnings of modern Korea, while adjacent places like Duksugung, the Anglican church, and the Seoul City Council building have also been historic urban landscapes of the historical layers of time as the city has changed. When Gojong announced the Korean Empire, the city structure was remodeled with this site as the center along with Sogong-ro, Wongudan and so forth. In this study, public interest stated in the guidelines was focused and the relevance of the road and the plaza was considered from the view of an historic urban landscape by a comprehensive analysis with Sejong-daero as the center. The restoration of public interest was to be drawn as the concept of the object site by considering the current status and the change around the site and Jungdong at the rear. Returning the site to the public is ambiguous with the relevance of the restoration of public interest and as the symbol of the idea of the Korean Empire by Gojong's announcement. The object site, having the characteristic of being returned to the public, must ensure public interest and therefore the design strategy has been established with the keywords of openness, connection and void. As a result of a review of the alternatives, a plan for a square has an 8% slope, just as the original site does, and provides ramps for convenient access for all, including the disabled and the elderly, and is connected to the grounds adjacent. No construction is allowed at the terrace square of the Anglican church level and the main square connected to the pedestrian street, so a variety of modern city utilization can be done. The value of the site at which this design is aimed shall be given back to the public with the concepts of modern democracy, independence, and the vision of Gojong by reinterpreting the space from a modern viewpoint. This study focused on the processes of establishing a main concept and strategy rather than the content of the design details, and the suggestion is meaningful in that the design for the object site with historic backgrounds and the layers of time can continue to be grown.

The present study was conducted to investigate smoking status and the relationship of smoking to hypertension and diseases on 1,504 subjects who were over 30-year-old age in Kyungsan Gun, Kyungpook province, during the period of 12 months from March 1978 to February 1979. The results obtained are summarized as follows: Of 1,504 subjects, 52.2 percent smoked. The percentage of males smoking showed 84.8 and the percentage of females was 30.7. There were no statistically significant differences between the rate of smoking and educational levels. Protestants demonstrated lower rates of smoking compared with other groups. Regarding the age started to smoke, 66.4 precent of male smokers and 16.9 percent of female smokers commenced smoking before the age of 19. In the regard to the average number of cigarettes smoked daily, 45.8 percent of male smokers consumed some 20 cigarettes and 24.1 percent of female smokers consumed some 10 cigarettes. 3.2 percent of male smellers smoked 40 or more cigarettes a day. Alcohol consumption was closely associated with smoking. 90.7 percent of male alcohol drinkers and 60.1 percent of female drinkers smoked. Cigarette smokers have higher rates of ailments than nonsmokers as a whole. The complaints of cough with sputum and shortness of breath revealed higher rates among smokers than among nonsmokers. Frequency of illnesses showed higher for smokers than for nonsmokers. Smokers were more likely than nonsmokers to suffer from chronic obstructive lung diseases such as chronic bronchitis, asthma, and emphysema. Abnormal systolic blood pressure (>160mmHg) and diastolic (>100) revealed significantly higher among smokers than among nonsmokers.

To propose quality improvement for commercial sikhe, we assessed the opinion of Food and Nutrition specialists about the status of utilization, preference and quality of commercial sikhe. Questionaires were hand-delivered to 530 subjects consisted of University students and faculties of Department of Food and Nutrition at 8 cities (Seoul, Incheon and Gyeonggi, Daejon and Chungnam, Cheongju and Chungbuk, Daegu and Gyeongbuk, Jeonbuk, Gwangju and Jeonnam, Husan and Gyeongnam) in Korea and the complete data of 328 subjects were statistically analyzed using SPSS Program for Window (mean, $\chi$$^2$, t-test, Pearson's correlation coefficient). Questionaires were consisted of sociodemographics, frequency and occasion of purchasing, opinion of quality and improvement points and sen-sory characteristics. Occasion of purchasing commercial sikhe is in order of ordinary day> for present> special day. Most subjects answered that commercial sikhe was different from home-made one. The reasons not to per-chase were the most in no preference and the next, in seeming to be different taste from home-made one. Points for further improvement in commercial sikhe were in order of taste> amount and floating of rice >flavor. The correlation coefficients between over-all preference and sensory characteristics showed positively in taste (0.54), texture of rice (0.476), content of malt (0.398).

Purpose: The aim of the present investigation was to understand the incidence, prevalence of denture stomatitis in denture wearers, who were over 60 years old, and use the results for a fundamental data to promote public awareness about denture stomatitis and its education tools. Materials and methods: From August 21 to September 8 2017, 500 denture wearers, who were more than 60 years old in Seoul and 4 other metropolitan cities (Busan, Daegu, Gwangju, and Daejeon), received questionnaires. The questionnaires included denture wearers' demographic distributions, specific dental treatment experiences, discomforts with current dentures, their oral health conditions, and the method of denture cleansing. Results: Thirty-two percent of 500 denture wearers responded that they have healthy oral conditions. Two hundred and eight respondents (41.6%) were aware of denture stomatitis. Only 131 (26.2%) were informed about the removable denture covered by national health insurance and 327 (65.4%) of denture wearers were using the improper denture cleansing methods. Conclusion: A large number of denture wearers still do not recognize the importance of proper treatment for denture stomatitis, insurance covered denture treatments, and adequate denture cleansing methods.

This study investigated the Present status of laboratories for experiment and practice, and analyzed teachers' recognitions on experiment and practice for Home Economics area of a Technology and Home Economics curriculum according to majors of teachers. Questionnaires were mailed to middle school teachers who taught home economics part and they answered on the web. 220 replies were used for the final analysis. The findings were as follows: First, the facilities and teaching equipments of laboratories for home economics area were inferior, especially, for clothing and textiles part and housing part. Second, teachers recognized necessity to conduct experiment and practice highly. Food life part scored the highest, while housing part scored the lowest. Teachers who majored in home economics recognized more necessities of experiment and practice than teachers who didn't majored in home economics. Third, they recognized level of experiment and practice to be suitable to students, but 'maintenance and repair of housing' section was relatively less suitable than other sections. Fourth, 'making clothes and recycling' section was recognized to have the least suitability in quantities and hours of experiment and practice lesson, because of too much contents and lack of lesson hours. Fifth, teachers recognized that students were more interested in 'the basis of food preparation and practice' section, but they are less interested in 'maintenance and repair of housing' section. Sixth, teachers recognized that contents of experiment and practice were very useful to the real life. 'The basis of food preparation and practice' section was the most useful, while 'maintenance and repair of housing' section was the least useful. Seventh, experiment and practice lessons for food life part were put in practice very well, followed by the order of clothing and textiles part and housing part. Teachers who majored in home economics usually took more experiment and practice lessons than teachers who didn't major in home economics.

This study examines the relationship between the organizational general characteristics (industry, size, location, development stage, and company age) and success factors of Korean venture firms using secondary data. Among the industries with the highest sales figures in 2016 are food / fiber / (non) metals, and the smallest category was software development. The sectors with the highest net profit were computer / semiconductor / electronic components, and the smallest category was telecommunication equipment / broadcasting equipment. The industries with the largest sales growth rate are IT / broadcasting services and software development. The industries with the highest net profit margin of sales are energy / medical / precision, and the smallest is telecommunication equipment / broadcasting equipment. In terms of the number of employees, venture firms with more than 100 employees have the largest sales and net profit, with employees between 1 and 9 have the smallest. However, these results are predictable. In general, the number of employees is highly correlated with sales and net profit. Rather, the sales growth rate and the net profit margin of sales may be meaningful. In particular, with employees between 50 ~ 99, the growth rate of sales and the net profit margin of sales were high. In terms of location, Seoul / Incheon / Gyeonggi were the regions with the highest sales and Daejeon / Sejong / Chungcheong / Gangwon were the least regions. Gwangju / Jeolla / Jeju and Seoul / Incheon / Gyeonggi were almost similar in the areas with the largest net profit. However, Daejeon / Sejong / Chungcheong / Gangwon had the lowest net profit. Unusually, the areas with the highest sales growth rate and the highest net profit margin of sales were Gwangju / Jeolla / Jeju, and the smallest areas were Busan / Jeonnam / Ulsan In the relationship between the stage of development and the performance of the company, the sales of maturity and decline stages were the highest and establishing stage was the lowest. Net profit was also the highest in mature stage and the smallest in establishing stage. The sales growth rate shows a typical pattern in the order of establishing stage, early growth stage, high growth stage, maturity stage, and decline stage. In terms of business performance, sales and net profit are the highest with 21 years or more of company age, and the smallest is less than 3 years. In addition, the sales growth rate was the highest in three years or less, and the net profit margin of sales was the highest in 4 to 10 years. This study can present lots of useful implications by suggesting integrated research model and examining the success factors of Korean venture firms and presenting the application methods of secondary data in analyzing the current status of venture industry in Korea.

The purpose of this thesis is to find the effective way of practical education in the fashion related department in order to supply the appropriate experts to the Korean apparel manufacturers located in Dalian, China. The interviews were made twice from $25^{th}$ of Feb. to $15^{th}$ of Mar. 2005 and from $28^{th}$ of July to 31st of July 2005 through the method ot a direct interview with the CEOs of the 7 representative apparel manufactures. The results of the interviews were as following. Seven companies$(100\%)$ participated in the survey all complained of insufficient workers. Also the companies were having difficulties at finding appropriate workers who can handle designing, management, and circulation, because specialists who are fluent in Korean and Chinese are very rare. Moreover, Korean apparel manufacturers are now taking a step further to launch a high quality fashion brand, getting out of the simple hand work depending on low wage or low-tech(6 companies $85.7\%$). Thus, well-educated fashion specialists(intermediate manager) are required on the part of Korean clothing companies or apparel manufacturers in China. It is expected the intermediate managers and the specialists who are capable of launching a new brand will be urgently needed. Therefore, appropriate educations in Korea would be essential to minimize the problems the Korean fashion specialists might face in China. 1 would like to present three suggestions. 1. The highly educated Korean fashion specialists on apparel industry will be a solution both to the high jobless status in our country and to the deficiency in human resources of Korean apparel manufacturers in Dalian. 2. The students in the college should learn how to write down the working chart and matching chart in practical conditions. Taking an intern-ship in working factories in China during a certain period of time will be helpful. 3. The experts should be trained with emphasis on the quality, design, and value of the brand. This study will be used as a base for Koreans who work in fashion related department to enter the Chinese fashion market having a great potential.

As epidemiological parameters of human paragonimiasis, the positive rates of intradermal test and the sputum/stool ekaminations have long been employed in population surveys. However, both the specificity of the intradermal test and the sensitivity of sputumjstool examination have been gradually declined as the endemicity was lowered; thus the gap between above two parameters widened. In such context, the development of a new epidemiologic parameter or tool which makes it possible to accurately discriminate the active paragonimiasis cases was necessary. In the present study, the detection rate of Paragonimus-speclac IgG antibody by micro-ELISA was evaluated as an indicator of epidemiologic status of human paragonimiasis in a population. A total of 4, 285 students and inhabitants living in Bukpyeong Myeon and Bukil Myeon, Haenam Gun, Jeonlanam Do was surveyed in October, 1983 by intradermal test first. Out of them, 244 cases (5.7%) were found positively reacted to VBS antigen of F. westermani. Out of 168 positive reactors, 7 cases (4.2%) were egg positive either by two times of sputum examination or by one stool examination. That indicated that only 0. 16% of total surveyed were confirmed as active paragonimiasis by egg detection. When sera collected from 239 positive reactors of Intradermal test were tested by micro-ELISA for their specific IgG antibody, 40 cases(16.7%) were found to be positive. All of 7 egg positive cases were again positive for specific IgG antibody. Among remaining 232 intradermal test positive cases, 33 cases were positive for IgG antibody. In contrast to those, none of 42 positive reactors to intradermal test for Cloncrchis and of 128 intradermal test negative cases showed positive for Paragcnimus-specIfic IgG antibody. The rate of specific IgG antibody as detected by micro-ELISA appeared to be increased with the wheal size of the intradermal test. When the wheal sixte was over 13mm in diameter, about 50% of them were positive for specific IgG antibody. Thirty-one specific antibody positive cases were clinically evaluated by laboratory examinations (repeated sputum examination, peripheral eosinophil count and chest roentgenogram) and by history taking. Out of them 24 cases were associated with one or more positive laboratory findings: thus considered as active paragonimiasis cases. Out of 7 lab. finding-free cases 3 revealed past history of typical paragonimiasis symptoms, suggesting that they were in chronic or in convalescent stages. The remaining 4 cases were considered as either mild or ectopic infection cases; the possibility of cross-reaction with other helminthiases could not be ruled out. From the above results, it was inferred that the detection of Paragonimus-specIfic IgG antibody by micro-ELISA was very much helpful in detecting the active cases as well as in proper evaluation of the endemicity of human paragonimiasis in a population. The convenience of mass haildling of sera in micro-ELISA was considered another superiority as an epidemiologic tool.

Korean government built "2040 Science and Technology Future Vision" in order to show positive future scenarios and suggest a long-term guideline for a progress in science and technology. The S&T Future Vision was built based on an analysis of global megatrends and a prospect of domestic social change. After building S&T Future Vision, the "Government R&E Strategy"s was established as a follow-up action plan. The Government R&D Strategy consists of lists of future emerging technologies for future leadership, government R&D investment status and investment portfolio plans. Exploring future emerging technologies aggressively and making a governmental R&D strategic policy are requirements for national competitiveness, leadership in the world. Therefore search and selection for future emerging technologies is getting more and more important recently. Generally qualitative methodologies have been used such as expert-panel discussion method and portfolio analysis with expert valuation method in order to explore future technologies. These experts-based qualitative methodologies are well defined but lacking in some objectivity because size of expert-panels has limitations. We suggest a quantitative methodology, science mapping method to compensate this shortcoming in this study. There is another limitation related governmental R&D strategy which is that general R&D portfolios are static until a point of technology realization. We also propose a dynamic R&D investment portfolio which present different portfolios at a intermediate point and a point of technology realization. We expect this try with science mapping method and a dynamic R&D portfolio could strengthen strategic aspect of government R&D policy.

Even though the anticarcinogenic effect of dietary factors especially beta - carotene has been reported by various investigators, the mechanism of the action of ${\beta}-carotene$ has not yet been identified. We carried out the present study to determine the possibilities of relative cancer risk related to dietary intake of vitamin A ( both ${\beta}-carotene$ and retinol ) and blood levels of vitamin A among Koreans. The subjects were divided into two groups; cancer patients and controls. Blood levels for ${\beta}-carotene$ and retinol were analyzed by alumina column chromatography and colorimetry. Dietary intake was examined by food profile and convenient method for evaluating nutritional status through recalling 10 years of food habits. The results obtained are as follows : 1 ) Calorie, protein, fat, and carbohydrate intakes of cancer patient were lower than those of control. Calorie and carbohydrate intakes showed no significant difference but protein and fat intakes were significantly lower in cancer patients. According to cancer sites, in stomach cancer only fat intake was significantly lower than that of control. In lung and larynx cancer calorie, protein, fat and carbohydrate intakes showed similar trend as in control. 2 ) Vitamin A intake of cancer patient was significantly lower than that of control. It was estimated that 83.6% of total Vitamin A intake were provided by ${\beta}-carotene$ for control and cancer patient respectively. 3 ) The mean intake of dietary ${\beta}-carotene$ in cancer patient was significantly lower than that in control ( $7002\;\mu}g/day$ versus $10326\;{\mu}g/day$ ) According to cancer sites in mean intake of dietary ${\beta}-carotene$ was significantly lower in all but stomach cancer compared with that of control. Lung and larynx cancer showed lowest ${\beta}-carotene$ intake with mean value of $5855{\mu}g/day$ and $5492{\mu}g/day$ respectively. 4 ) The mean intake of dietary retinol in cancer patient was significantly lower than that in control ( $245{\mu}g/day$ versus $338{\mu}g/day$ ), but the difference was not significant. 5 ) The relative risk of all cancers in the first (lowest) to the forth quartile level of ${\beta}-carotene$ consumption such as $0-5999{\mu}g/day$. $6000-8999{\mu}g/day$, $9000-11999{\mu}g/day$/ day and $12000-20000{\mu}g/day$ was 85 : 1.7 : 20 : 1.0. The relative risk of all cancers in the first (lowest) to the forth quartile level of retinol consumption, such as $0-299{\mu}g/day$, $300-599{\mu}g/day$, 600-899${\mu}g/day$, and $900-1200{\mu}g/day$, was 1.14 : 067 : 0.21 : 1.0. 6 ) The various food group consumption of cancer patient were significantly lower than those of control in green leafy vegetables, fruits, sea weeds, milk and cheese and eggs. But the Kimchie consumption in cancer patient was three fold higher than that of control ( $1840\;{\mu}g/day$ versus $562\;{\mu}g/day$ ) and in the stomach cancer, Kimchie consumption was the highest, ( $1890\;{\mu}g/day$) According to cancer sites, the consumption of green leafy vegetables was significantly lower in all but stomach cancer compared to control and other vegetables showed no difference between two. In lung and larynx cancer, green leafy vegetables consumption was lowest ( $6094{\mu}g/day$ $5921{\mu}g/day$) and milk and cheese consumption was also( $5\;{\mu}g/day$ and $11{\mu}g/day$) 7 ) The recovery of ${\beta}-carotene$ from human serum by alumina column chromatography was $94.4{\pm}2.3%$. 8 ) Cancer patients showed significantly lower serum retinol ($56.4{\pm}18.1\:{\mu}g/100ml$ versus $72.2{\pm}21.8\:{\mu}g/100ml$) and ${\beta}-carotene$ ($48.9{\pm}33.8\:{\mu}g/100ml$ versus $72.2{\pm}42.6\:{\mu}g/100ml$) concentrations than in controls. 9 ) But breast cancer patients were not significantly different from controls in their serum retinol and ${\beta}-carotene$ concentrations.
