A project to build a large oceanographic research ship was proposed to improve the level of ocean research. This paper attempts to measure the non-market benefits of the project. To this end, the dichotomous choice contingent valuation method is used. In particular, the recently proposed one and one-half bounded model is applied. The model can reduce the potential for response bias compared to the double bounded model, while maintaining much of its efficiency. Moreover, in order to deal with zero WTP observations, a spike model is adjusted for our data. A survey of 500 randomly selected households was implemented in the Metropolitan area. The respondents were asked in person-to-person interviews about how they would be willing to pay for implementing the project. Overall, respondents accepted the contingent market, and were willing to contribute a significant amount (3,244 won), on average, per household per year. The aggregate value of the project nationwide would amount to approximately 40.1 billion won per year.

A cross-sectional study was conducted to examine the prevalence and related factors of musuculoskeletal symptoms in automobile manufacturing, steel processing, electric assembly line, and wood processing industries. A study subjects were 3,434 workers from small and medium scale companies of Incheon. Walk-through surveys were performed from Feb. of 2004 to Oct. of 2004 to investigate various physical work factors. Symptom prevalence rate by related factors was that women worker showed higher rate than man, and married person was higher than single person. For the working year, group of person who were working less than 3 year showed the highest rate. However, the group of person who were working more than 10 hour per day showed the highest rate. For the total subjects, prevalence of symptoms by body area was as follows: shoulder symptoms were the most frequently reported symptoms(253 person, 7.0%), followed by back(155 person, 4.5%), hand or fingers (136 person, 4.0%), lower extremities(131 person, 3.9%), neck(108 person, 3.1%), and elbow symptoms(97 person, 2.8%).

The purpose of this research is to expand much more the facilities and collections of public libraries in Korea for performance of its function, for the life-long education institution. In order to accomplish the purpose of this study, I looked in to the present conditions of the facilities, collections, service facilities in public libraries and suggested a tentative plan on the basis of every kinds of statistics. The result of this thesis can be summarized as follows : 1. Now, 227, 110 populations of the effective service per library are so many that 181 public libraries in Korea have largely deficient state. To solve, a n.0, pplied for Armstrong's standards (5, 000 populations of the effective service per library, and the number of an elementary school 5, 412 elementary schools in Korea). In the former case should be establish 8, 221 public libraries, in the latter case should be established at least 5, 412 public libraries. 2. The public library in Korea is possessed of building areas of 82, 267 pyong (468 pyong per library). They are very poor state comparing with population. Therefore, the building area should be expand according to population by region. Also, the reading facilities of 88, 455 seats, 465 population of the effective service per seat, are largely insufficient of situation. And consequently they should be secured at least 205, 535 seats with standards of five seats per 1, 000 population. 3. The public libraries in Korea keep collection of 4, 517, 280 volumes. As there are 11 volumes per 100 persons, they are very deficient state in figures. Therefore, in this study, suggested Schenk's standard (1 volume per a person) and IFLA standard (2 volumes per a person). Under the circumstances of our country, however, they should be secure at least 41, 106, 993 volumes with a Schenk's standard of one volume per a person. To meet this kind of necessary conditions, there must not only be a national policy but also be a facility for every residents to utilize for educational place, and to every librarians of public libraries, they have to do their best to open their library to every citizens, when needed, with their self-conceit. Cooperating with policy-makers, users, and librarians, making every endeavors to develope Korean libraries, we can promise the hope that our public library will be progressed towards future.

Background: This study aims to figure out the gaps in health status by estimating amenable mortality rate by region, reflecting the characteristics of Korea, and estimating the years of life lost (YLL) per capita by disease. Methods: People who died from amenable diseases between 2008 and 2018 were extracted from the cause of death statistics provided by Statistics Korea. The age-standardized amenable mortality rates were estimated to compare the health status of 229 regions. YLL per capita was calculated to compute the burden of diseases caused by treatable deaths by region. The YLL per capita by region was calculated to identify the burden of disease caused by amenable deaths. Results: First, while the annual amenable mortality rate in Korea is on a steady decline, but there is still a considerable gap between urban and rural areas when comparing the mortality rates of 229 areas. Second, YLL per capita due to the amenable deaths is approximately 14 person-years during the analysis period (2008-2018). Conclusion: Although the health status of Koreans has continuously improved, there is still a gap in health status region by region in terms of amenable mortality rates. Amenable death accounts for a loss of life equivalent to 14 person-years per year. Since the amenable mortality rate is an indicator that can measure the performance of the health care system, efforts at each local area are required to lower it.

An emergy evaluation of the natural environment ant economy of Seoul revealed that Seoul used 1.27 E23 sej/yr of emergy in 1997. The emergy input from the Han River accounted for most of the renewable emergy sources. Emergy imported from foreign countries and other parts of Korea accounted for 97% of the total emergy use in Seoul in 1997, revealing that the economy of Seoul is more dependent on outside emergy sources than for the entire Korean economy. The emergy use per unit area(2.09 E14 sej/$m^2$/yr) was higher than that for the entire country or Pusan, whereas the emergy use per capita(1.22 E16 sej/person/yr) was lower than that for the entire country or Pusan. These results reflect the overcrowded conditions in Seoul where about one fourth of the Korean population now live. They also seem to indicate a lower living standard in Seoul than the average in Korea. The quality of living in Seoul could also be judged by a high environmental loading ratio and a low sustainability index. All there indices suggest that people in Seoul live under a higher environmental stress than the average person in Korea.

Water is an indispensable input to human's existence and industrial production. In these days, people are getting more concerned about their health and the interest in the safety of drinking water has increased. In this situation, this paper attempts to measure the economic benefits of the tap water quality improvement. The study area was restricted to Busan, the second largest city in Korea, where local government is planning to implement a tap water quality improvement program. We apply a one-and-one-half bounded dichotomous choice contingent valuation (CV) method to obtain at least a preliminary evaluation of the benefits. CV is developed for valuing goods or services that cannot be valued either directly or indirectly from market observations and has been applied to several environmental goods. The CV survey was rigorously designed to comply with the guidelines for best-practiced CV studies. We surveyed a randomly selected sample of 400 households in Busan and asked respondents questions in person-to-person interviews about how they would be willing to pay for the water quality improvement. Respondents overall accepted the contingent market and were willing to contribute a significant amount (US$1.66), on average, per household per month. We can also calculate the aggregate value of the program which improves the water quality in Busan. This study is expected to provide policy-makers with useful information for evaluating and planning environmental policies relating specifically to water.

The purpose of this study is to examine the factors related to leisure time to understand middle-aged one-person households. Data are from the recent survey of lifetime use in 2014 by Statistics Korea(N=1,138). Middle-aged one-person households aged 40-59 years were categorized into four groups by marital status (unmarried/married/widowed/divorced). Major results were found as follows: First, the total leisure time per day was 238 min in the middle-aged one-person households. The majority of the total leisure time was spent on 'fellowship & leisure activities'(204 min on weekdays, 283 min on weekends). Especially, time spent on real-time TV watching hours was the longest, as long as 89 min on weekday and 150 min on weekends. Second, gender differences were significant in terms of leisure time use in the middle-aged one-person households. Females spent less time on leisure than their male counterparts on both weekdays and weekends. In addition, gender differences related to marital status were significant. Third, on weekdays, the determinants of leisure time use among the middle-aged one-person households were health and type of employment for 'participation & volunteer activities', and gender, age, marital status, and type of employment variables for 'fellowship & leisure activities.' On weekends, time spent on 'participation & volunteer activities' were influenced by marital status, residential area, and type of employment, while time spent on 'fellowship & leisure activities' were significantly related to gender, type of employment, type of job, holiday system, and income.

This study is based on data from the nutritional and clinical survey in Chung Nam area, namely Myl-Yang-Ri, Yoon-Gok-Myon, Chyung Yang Koon. Under the direction of two Nutrition professors and two clinical pathology professors it was carried by 35 Dae Jeun medical Junior College students majoring in nutrition and clinical pathology from 18 July to 25 July 1978. The nutrition surveys were carried out with subjects in village from a total 67 households, 36 of them were randomly selected. The clinical surveys were carried out with subjects in village from a total 382 inhabitant, 154 inhabitant were randomly selected and 109 peoples were subjected to stool examination. The results obtained in this study are summarized as follows. 1) Nutritional survey a) Food Intake The average food intake per person per day in survey area was 929.9 grams (95.5% in vegetables and 4.5% in animal foods). The average consumption of the basicfood groups per person per day was 965g for meats and legumes (10.4% of the total food in take). 268.9g for fruits and vegetables (29% of the total food intake), 559.1g for cereals and potatoes(60.1% of the total food intake), 5.2g for milk and small fishes and 0.2g for fats and oils. b) Nutrient Intake The average daily consumption of calories and nutrients was 2054.1 kcal and 61.2g for total proteins, 223.2mg for calcium, 9.5mg for iron, 4914.4 IU for vitamin A, 1.5mg for thiamin, 1.2mg for riboflavin, 19.9mg for niacin and 54.7mg for ascorbic acid. When these figures are compared with the recommended allowances for Korean, the calories and nutrients intakes were insufficient. Especially the intakes of the calcium were lower than the recommended allowance which are 500 milligrams per day. c) Kinds of food stuffs consumed The kinds of food stuffs consumed by the subjects were 47 figures total. Generally these kinds of food were vegetables food. 2) Clinical Survey a) The mean value of hemoglobin from 72 males was 13.2g/dl, that of 82 females was 12.3g/dl. b) The proportion of low hemoglobin (<12.2g/dl for male and <11.3g/dl fo female) for male was 20.8%, females was 11.0% and from 24 male & female (both sexes) were 15.6% c) The mean value of Hematocrit of males was 39.6%, that of females was 37.4%. d) The mean value of MCHC of males was 33.9%, that of females was 33.6%. e) The ABO blood group was distributed as following; 30.5%, for group O, 29.2% for group A, 24.0% for group B, and 16.3% for AB group. Biochemical race index was 1.13. f) The over all prevalence rate of heminthic infectious by rate of each helminth was as following; Ascaris lumbricoides 33.9%, Thrichocephalus trichiurus 11.9%, Hookworm 0.9%, Hymenolepis diminuta 0.9%, Trichostromgylus orientalis 0.9% and the prevalence rate of two more helminthic infection was 7.2%.

The author has conducted survey on the status of physical growth and morbidity of the children for christian children's fund programme, as a means of collecting basic data for the anticipated establishment of a health planning. A total 345 children aged 9 to 16 underwent C.C.F. programme while as a control, a total of 480 children of same ages from the middle-class school children in Jeonju area was also studied. As results of survey conducted for a period of one month (form July 1 to 31, 1974) on a total 429 children in 347 households living in Jeonju area. I. Socio-economic background 1. By educational status of the children, 39.9 per cent of the total children was attending at primary school, 33.8 per cent in middle school and 15.6 per cent in high school. 2. The greatest proportion or 28.8 per cent of the household head were engaged in labor, 17.9 per cent in peddler and 13.2 per cent in retail. 3. As for the living standard of the households, low class constitued 90.1 per cent, middle and high classes only 9.9 per cent. 4. 39.5 per cent of the households had their own house, 39.1 per cent lived in rent deposit house or rooms and 14.6 per cent in monthly rented house and rooms. II. Physical growth and nutritional status 1. The growth of children for C.C.F. programme in terms of height was found to be slightly smaller than the school children. The ages frm 9 to 16 corespond to the 'secondary growth and replenishment period and this period was regarded to be the one most affected by environmental and nutritional factors of all the other periods of growth and developmet. 2. The body weight of the children for C.C.F. presented a quite different pattern from that of the school children. The above findings appeared thin-and-long stature from the famillies with higher living standard while those from the household with low standard of living had a short-and-plump one. 3. According to the values of Rohrer's index, the children of C.C.F carried a higher degree of 'replenishment' than the children in Jeonju area and adolesecence comes later for the girls under C.C.F. programme. III. Morbidity 1. The monthly prevalence rate was 110.0 per thousand persons for the children under C.C.F. programme. 2. The total number of case was classified by timing of the incidence as follws. 40.0 per cent was constituted by diseases carried over from tile previous month and 60.0 per cent by new incidences. 3. The diseases were broken down by W.H.O. disease classification into the greatest proportion or 39.1 per thousand person constituted by disease of the digestive system.
