Since 1962, the population growth control has been one of the most important aims in the 5-Year So-cioeconomic Development Plans of Korea. The annual population growth rate has dropped to tess than 1 percent in 1990 from about 3 percents in 1960s, and projected to reach to $\ulcorner$0$\urcorner$ percent in 2021. From 2021, Korean population will decrease and the age structure will be distorted because birth rate will drop suddenly and continuously. Thus, we can consider $\ulcorner$0$\urcorner$ growth population for minimizing the prob- lems on the decreasing population. To discuss the problems caused from the changes of population size and age- sex composition, we projected three kinds of population including two kinds of $\ulcorner$0$\urcorner$ growth population under different as- sumptions. The first is the population which extended the projection of National Statistical Office up to 2090. Because the TFR is assumed and fixed as low as 1.63 after 1990, the population growth rate will be under $\ulcorner$0$\urcorner$ in 2021 and drop by about 1 percent every year from around 2050. This population trend results to old age population : 38.1 of old- age dependency ratio and 46.5 years of median age. The second is the population which the size in 2021 projected by the NOS continues after 2021. To change over from the decreasing population after 2021 to the $\ulcorner$0$\urcorner$ growth one, the TFR should be in-creased up to over 3.0 in 2040-2050, which fertility level would be too high to be accepted. The third is the population which approaches to the $\ulcorner$0$\urcorner$ growth population under the assumptions that the TFR increases from 1.63 to 2.1 in the period of 2010-2030 and then the same level continues. Although the maximum population size reaches 51, 503 thousand persons, the population will approach to the stationary population with about 42.4 million persons around 2090. In this projected population there is no more serious problems on population composition, on the rapid decrease of population, and on the increase TFR level. When the $\ulcorner$0$\urcorner$ growth population continues the problems of over population caused by the populationincrease wou]d be minimized, and the problems of unusual age composition resulted from the popula-tion decrease would not be found any more. Furthermore, when the changes of population size and composition is continuing slowly, the factors of population would effect moderately to socioeconomic development and help social changes. Therefore, with the attention of the present population changes, we should adapt new and detailde population policy which is able to get the $\ulcorner$0$\urcorner$ growth population.

The water temperature distribution and the water movement closely related with it, in the east side of Korea, was condidered. Special emphasis was paid on the low temperature phenomenon near Ulgi. It was known from the temperature distribution in the east side of Korea that the Tsushima current continues to flow northward at the surface near Sokcho. Also the influence of the cold water extends from the North to the South with increasing depth. The formation of the cold core near Ulgi was explained as due mainly to the existence of the boundary layer near the surface, and partly to the effect of the wind. This inclination of the boundary layer has the value of about 3.0m/Km, and the lower cold current velocity computed using this value lies in the range of those observed by Nishida(1926, 1927). The upwelling velocity was computed approximately as 1.4 10$\^$-3/ cm/sec, and the maximum distance to which the boundarylayer can rise or fall from it's equilibrium position was considered as below 10m.

The trade balance for the information and communications technology (ICT) industries in 2014 have reached 863 hundred million dollars as the main export products such as smart phone and semi-conductor increase, since the ICT industries have played an important role in economic growth in Korea. Until now, the consistent supporting of government and investment of company have been doing with the growth of ICT industries, as a result, Korea marked as the first in the UN electronic government preparing index, and rank 12 in the network preparing index through the policy of national information and basic plan of inter-industry convergence. However, as the unstable international economic circumstances, ICT industries is faced with the stagnation, and then preemptive development of products and services for ICT convergence industries is needed to continually get definite ICT Korea image. In this paper, the ICT convergence industry is analyzed and forecasted. In specific, the international and domestic market for cloud, 3D convergence, and internet of things is diagnosed. The market for ICT convergence industries is predicted to be 3.6 trillion dollar in the world, and 110 trillion won in domestic. From the analytical results for technology and services development, the preemptive supporting of the technology development and policy for the internet of things and 3D convergence industries is required. In addition to, through the future forecasting by socio-tech matrix method, the policy supporting for the ICT convergence area of healthcare, fintech, artificial intelligence, body platform, and human security is needed.

To research the changes of Ramyun in Korea, this paper was went over an historical study through the content analysis of ads. from 1963 to 2012. The study period was divided into 6 stages based on GNI(Gross National Income). The advertisements were classified into new advertisements and all ones, and the advertisements of new Ramyun were categorized with 4 ways. And the most emphasized messages of advertisements and advertising models of each periods were also examined. The total number of new advertisements was 185(3.7/y) and 650 total advertisements(13.7/year). The most emphasized messages were changed from 'taste' and 'high calorie' to 'noodles', 'function(specific nutrition)'. The advertising models were actors, comedians, popular singers, in turn. The 1960's was the period when the fewest new products were advertised to consumers most often. 1980-1996 was the period when the most new products were advertised the most. During the depresseions, all ads were more frequently and new ads were lower advertised. Above results, each period was named as follow, respectively ; the Expansion period(1963~1969), the Set-up period(1970~1979), the Competition period (1980~1987), the Bipolarization period(1988~1997), the Transition period(1998~2003), the Stabilization period(2004~2012).

The history of modernization of Korea is divided into two folds of the colonial era in the 20's and the economic development era in the 60's. Most of the spaces built in the process of modernization were public spaces developed by the drive of the government. These spaces of modernization are functionality-oriented public places of production and at the same time, and they are the spaces of national power to symbolize the identity of national authorities. Along with changes in the society, modern spaces were reduced down to monument buildings without functionality and this requires new definition to renew the identity of modern spaces. Small stations, power plants, mines, warehouses, abandoned factories, and etc... the study has paid attention to the process of changing thought, one of the main characteristics of modernization, the relations of modern concepts projected in the spaces, framework of modern society, and placeness in the process of framework building and relations of people in the spaces with video records on the process of rebuilding new identity of modern spaces and memories of the spaces. The relations of modern spaces and memory were explored in < Seoul Station > while the relations between modern spaces and records and place identity were explored in < Onyang Folk Museum > and < Okpo Shipyard > respectively. In the relations between space identity and memory in each space, the ironic relations of power in modern spaces (placeness) and personal narrative (memories) were explored with oral narrative and video footage.

The public organization in the metropolitan area moved to regional province by Regional Innovation Policy in South Korea. This policy was settled to solve the problem of concentration in metropolitan areas and underdeveloped regions caused by industrial development strategy for 40 years from 1960s till 2000s. Government decided the plan under the judgement that moving public organization (or institutions) is one of National Innovation Strategy for balanced development. Furthermore, Central organizations/institutions were to be the subject of regional innovation by leading the regional innovation and building a new regional innovation system. The Purpose of this study is finding out the new direction of regional innovation paradigm and a new regional innovation system to be changed after previous public organization moving from metropolitan area to region province. And this study pointed up the problem between plan and process of Organization Removal, suggested the topics for success of New RIS, and prepared more details methods in future study.

Korea domestic casino industry has been experienced an explosive growth marking the highest quantity and quality with rapid growth of domestic economy since the 1960s. However there are really lack of study about presenting guideline for establishing risk management planning reflected characteristics of casino industry. Therefore, we analyzed previous studies about concept of the risk and criteria and drew dimension of safety supervision reflecting characteristics of casino industry. we, also, identified detailed safety management factors as well as classified three dimensions of environment, human and facility on the dimension of safety supervision. This study was designed to examine effect relationship between risk management factors and performance of security management organization focused on The mediation effect of atmosphere of organization We used two different tools for data analysis: SPSS 18.0 for the descriptive statistics and PLS 3.0 to validate the integrity of the research model and proposed hypotheses that is main effects from risk management factors to security management organization and mediation effects of atmosphere of organization. The data analysis confirmed the importance of risk management factors to enhanced performance of security management organization. The mediation effect of atmosphere of organization, also, supported relationship between risk management factors and performance of security management organization. It provided theoretical and practical implication for building risk management strategy well suited casino company and conducting security management.

The Recommended Dietary Allowances(RDAs, Nutrient standards), dietary guidelines, and food guides, each define aspects for a healthy diet in different ways. The RDA and food guide for Koreans were first established in 1962 by the Food and Nutrition Committee of the Korea FAO Association. The committee released the RDA and suggested ways to intake the recommended nutrients. Every five years, the committee has added more data and released revisions. The latest edition of the RDA is the 6th revision. In the beginning, the concept of basic food groups was emphasized as basic data for planning means based on RDA. In the 5th revision, the basic food groups and dietary guideline for public health from the Ministry of Health and Welfairs(December, 1990) suggests that, 1) Eat a variety of foods with a recommended fat intake equaling or less than 20% of total calories ; 2) Maintain ideal body weight and prevent obesity ; 3) Eat foods low in salt. Salt intake should not exceed 10g ; 4) Do not drink too much ; 5) Eat regularly and enjoy meals. After these guidelines were established, the first nutritonal education efforts guidelines were developed in 1984. Despite broad possibilities for application, they had limited use, mainly as a nutritional assessment and food balance sheet preparation. They were not well utilized in public nutritional education and nutritonal policy through the media because of the weakness of the government's food and nutriton policy. Also a lack of administrative support and dietitians in the health department and administrative organizations was partly to blame. In regard to public health and nutrition status, life expectancy has increased 10 years since the 70's and the elderly population increased threefold in 1995 compared to 1960. The common causes of death in 1996 by 19 Chapters classification, were first disease of the circulatory system ; the second, neoplasms ; the third, external causes fo mortality ; the forth, diseases of the digestive system ; and the fifth, respiratory system diseases, In food intake, grain and complex starch intake has decreased while fruit and animal foods have considerably increased. Therefore, energy from carbohydrates has decreased while energy from protein and fat has increased. Energy intakes from protein, fat and carbohydrates were respectively 12.5, 7.2 and 80.3% in 1969 but 16.1, 19.1 and 64.8% in 1995. 62.9% of the householes had the fat energy less than 20%, while 37.1% had the fat energy above 20%. The only intakes of vitamin A and calcium were below RDA levles. Therefore, nationwide attention should be focused on public nutriton education and public activities with supplementation of the RDAs, according to the food guide and the dietary guideline.

Background: The poultry industry in Pakistan has flourished since the 1960s; however, there are scarce data regarding the impact of occupational exposure on the pulmonary health of farm workers in terms of years working in the industry. The objective of the present study was to assess the effect of poultry environment on the health of occupationally exposed poultry farmers in countries of warm climatic regions, such as Pakistan. This study will also show the effect of exposure to poultry facilities on the health of poultry farmers in the context of low-income countries with a relatively inadequate occupational exposure risk management. Materials and methods: The lung function capacity of 79 poultry workers was measured using a spirometer. Along with spirometry, a structured questionnaire was also administrated to obtain information about age, height, weight, smokers/nonsmokers, years of working experience, and pulmonary health of farm workers. The workers who were directly involved in the care and handling of birds in these intensive facilities were considered and divided into four groups based on their years of working experience: Group I (3-10 months), Group II (1-5 years), Group III (6-10 years), and Group IV (more than 11 years). The forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and the FEV1/FVC ratio were considered to identify lung function abnormalities. Statistical analysis was carried out using independent sample t test, Chi-square test, Pearson's correlation, and linear regression. Results: Based on the performed spirometry, 68 (86 %) of workers were found normal and healthy, whereas 11 (14 %) had a mild obstruction. Of the 11 workers with mild obstruction, the highest number with respect to the total was in Group IV (more than 11 years of working experience) followed by Group III and Group II. Most of the workers were found healthy, which seems to be because of the healthy survivor effect. For the independent sample t test, a significant difference was noticed between healthy and nonhealthy farmers, whereas Chi-square test showed a significant association with height, drugs, and working experience. Linear regression that was stratified by respiratory symptoms showed for workers with symptoms, regression models for all spirometric parameters (FVC, FEV1, and FEV1/FVC) have better predictive power or R square value than those of workers without symptoms. Conclusion: These findings suggest that lung function capacity was directly related to years of working experience. With increasing number of working years, symptoms of various respiratory problems enhanced in the poultry workers. It should be noted that most of the poultry workers were healthy and young, the rationale being that there is a high turnover rate in this profession. The mobility in this job and our finding of 86% of the healthy workers in the present study also proposed healthy worker survivor effect.
