Korean pines(Pinus koraiensis) are one of the major plantation species in the Republic of Korea and their natural habitats range from Japan and China to Siberia. The seed of Korean pines, pine nuts, are well know for good food reserves. Due to the global changes which drive the Korean peninsula into the semi-tropical climate, current plantations and natural habitats of Korean pines are faced with the change in the environmental conditions to some extent. To anticipate suitable sites for Korean pines in the future, the location of Korean pines were extracted from the 'Map of suitable trees on a site' that provides the map of suitable trees on a site considering tree species for timber and special uses, and then MaxEnt modelling was used for generating a prediction map on the basis of statistical analysis. As a result, the order of predicted suitable sites were Kangwon-do, Kyungsangbuk-do and Chungcheongbuk-do provinces and sites with high elevation within those provinces were considered most suitable in common. The prediction map of suitable sites for Korean pines presented that suitable sites in the future decreased by 72.2% by 2050's and almost disappeared with a decrease of 92.1% by 2070's on a nationwide scale. In relation to the major production regions of pine nuts in South Korea - Gapyung gun and Yangpyung gun, Kyunggi province and Hongcheon gun, Kangwon province, suitable sites within their areas were predicted to increase by 2050's but become extinct in South Korea by 2070's. To establish a long-term countermeasures against the improvement on forest productivity quality in terms of managing national food security, the result from this study can be considered as a firm basis of predicting plantation suitability. Also, it can be used to predict the changes in supply of forest products and thereby market values in accordance with climate change scenarios.

Trichloroethylene(TCE) is widely used as a degreasing solvent in workplaces. TCE is primarily toxic to the nervous system, however, systemic disorder like Stevens-Johnson syndrome has been recently reported in small-scale factories, where the government has had limited information of chemical use. A survey was performed to investigate the actual condition of using TCE and to provide practical information to occupational health service agencies and professionals. This survey was carried out on 103 factories out of 430 factories which were conducted periodic work environment measurement for TCE. Degreasing was the most popular reason for using TCE in Korea, which reached to 94%. TCE was also used as a solvent for rubber in the coating or molding process, and adhesives in the bonding process. Metal fabrication was the most common as 23%, followed by assembling automobile parts (17%), and machinery (12%). Workers exposed to TCE during full-shift were 52% while 48% were exposed during short period of the shift or intermittently. Manual or semi-automatic work occupied 87% while automatic work was just 13%. Though automatic work by a closed system was generally lower exposed to TCE, compared to manual work, it can cause a high exposure when the maintenance system is improper. Semi-automatic work especially like open-top degreasing process can cause a high exposure when local exhaust system with condensing and refrigerating coils in the degreaser does not work well. In conclusion, the survey showed nationwide status of TCE exposure in various aspects. It can be used to monitor workplaces and workers exposed to TCE to prevent occupational diseases.

Korean government has planned a large scale multidepartment-participated national R&D program to advance and improve her science and technology and the quality of life In the level of advanced(especially G-7) countries in the forthcoming 21st century. It is called as "Highly Advanced National projects" or "G7 projects", which was initiated in 1991 with 18 sub-programs to date. It has planned to be continued until 2001 with its total fund of 4, 591 billion Won, comprised of 2, 033 billion Won from the public sector and 2, 558 billion Won from the private sector. Evaluation activities, the country has carried out to date, for national R&D programs including HAN projects are focused mainly on the assessment of scientific and technological results to decide that a specific program should be continued, terminated, or modified. Thus, it is necessary for national R&D programs to be evaluated socioeconomically for the purpose of assessing the nationwide economic and social impact from the program. Socioeconomic evaluation would be told how and where the program contributed to the society, and what the socioeconomic impacts are resulted from the program. It would be useful for the means of (ⅰ) fulfillment of public accountability to legitimate the program and to reveal the expenditure of pubic fund, and (ⅱ) managemental and strategical learning to give information necessary to improve the making. program and policy decision making, The objectives of the study are to develop the methodology of modeling the socioeconomic evaluation, and build up the practical socioeconomic evaluation model of the HAN projects including scientific and technological effects. Since the HAN projects consists of 18 subprograms, it is difficult In evaluate all the subprograms simultaneously. Despite, each program is being performed under the category of HAN projects, so the common socioeconomic issues are existing, The followings are main results of the study. First, the hierarchical structure of the socioeconomic evaluation are constructed; Evaluation Perspective, Evaluation Bounds, and Evaluation Aspect. Second, based on the goals of the HAN projects, the evaluation perspectives are established as (ⅰ) the strengthening of industrial competitiveness, (ⅱ) the enhancement of national scientific and technological capability, (ⅲ) the improvement of quality of life. Third, the evaluation bounds for each evaluation objective are defined to specify the affected area. Finally, the evaluation aspects for each evaluation bounds are formulated containing essential elements describing the evaluation bounds.

Acquired Immune Deficiency Syndrome is the state which develops after complications with the infection from HIV. Irrespective of their state, all HIV infections have infectivity. According to a 2013 U.N. AIDS global report, the number of reported newly infected with HIV is constantly falling, while that of Korea has been increasing over recent years and it surpassed 10,000 in 2013. This phenomenon might be attributed to the unusualness of the blood test for early detection of HIV infection. From this fact, we can assume that we have strong possibilities for encounters with infections in the office. But many misconceptions about the disease makes patients try to hide their medical history, which can lead to a nationwide spread of the infection without proper management. Even though it may be difficult to take care of HIV patients in smaller dental offices, large scale hospitals have the means to arrange protocols to treat them. We present a case about dental treatment of a patient with AIDS that has a history of cerebral infarction and hepatitis type B under general anesthesia. The purpose of this case report was to discuss the special considerations of dental care for patients with HIV.

The purpose of this study were to find out the difference of needs of caring between care-givers and non care-givers, and to suggest the way of lessening vigorous task of care-givers for the elderly with dementia. Data were collected from 130 nationwide respondents intentionally divided into two groups; care-givers and non care-givers in the middle aged with middle and upper income. Collected data were analyzed by frequency, percentage, t-test using SPSS package. Since the result of survey, unexpectedly, showed no difference between two groups, it could be explained as that these two groups commonly had same needs of caring for the elderly with dementia. Major findings were as follow; 1) Most Koreans stiff thought family should be the main care-giver for the elderly with dementia prior to nation or society. 2) Responsibility of caring for the elderly with dementia would be better to be shared with children instead of focusing to a child. 3) They thought ideal residential facilities for the elderly with dementia were small-scale professional dementia facility(group home) rather than home or general elderly housing. 4) Professional dementia care hospital was one of the most needed facilities for the elderly with dementia, followed by short-stay and dar-care center. 5) It was revealed care-giving task was vigorous showing that most care-givers spent 1-5 hours a day for caring, while 13% of respondents spent 11-24 hours a duty. 6) 90% of care-givers took the responsibility of main care-giver because of duty of offsprings or spouses, and wanted to be free from their current circumstances. From the result of this survey researchers would like to suggest the establishment of diverse facilities for professional dementia care to lessen the caring burden for the elderly with dementia: group home, chronic hospital, short-stay, day-care center. Financial support from the government for the housing renovation of the caring families should be considered seriously afterward. It is needed to give the opportunity to select proper paid dementia care facilities according to their income and situation of household.

Objective: The purpose of this study was i) to identify the characteristics of carcass traits in Chikso by gender, region, age at slaughter, and coat color using the carcass data collected from the nationwide pedigree information and coat color investigation, and ii) to estimate genetic parameters for breed improvement. Methods: A linear model was used to analyze the environmental effects on the carcass traits and to estimate genetic parameters. Analysis of variance was performed using TYPE III sum of squares for the unbalanced data provided by the general linear model procedure. Variance components for genetic parameters was estimated using REMLF90 of the BLUPF90 family programs. Results: Phenotypic performance of carcass weight (CW), eye muscle area (EMA), and backfat thickness (BF) in Chikso were lower than those of Hanwoo. This is a natural outcome because Hanwoo have undergone significant efforts for improvement at the national level, a phenomenon not observed in Chikso. Another factor influencing the above outcome was the smaller population size of Chikso compared to that of Hanwoo's. The heritabilities of CW, EMA, BF, and marbling score in Chikso were estimated as 0.50, 0.37, 0.35, and 0.53, respectively, which were was higher than those of Hanwoo. Conclusion: Based on the genetic parameters that were estimated in this study, it is expected that the carcass traits will improve when the livestock research institutes at each province conduct small-scale performance tests and the semen is provided to farmers after selecting proven bulls using the state-of-art selection technique such as genomic selection.

Hwa-byung is a form of psychogenic illness among people in Korea and is listed as a culture-bound syndrome of Korea in the DSM-IV. Despite increased clinical researches for Hwa-byung in the oriental medicine of Korea, there has been no agreement of pattern identification for Hwa-byung. The purpose of this study is to develop a standard instrument of pattern identification for Hwa-byung which will be applied to clinical research. The items and structure of the instrument were based on review of published literature. The advisor committee on this study was organized by 15 neuropsychiatry professors of 11 oriental medical colleges nationwide. The experts attended 2 consultation meetings and discussed developing the instrument. and we also took professional advices by e-mail. The results were as follows; First, we divided the symptoms and signs of Hwa-byung into five pattern identification - stagnation of liver Qi, flare-up of the liver fire, disharmony between heart and kidney, deficiency of both Qi and blood, malfunction of gallbladder due to phlegm stagnation. Second, we got the mean weights to each symptom of five pattern identification which had been scored on a 5-point scale - ranging from 0 to 4 by the 15 experts. Third, we made out the Korean instrument of the pattern identification for Hwa-byung. It was composed of 34 questions and decided on question-and-answer form. Though there are some limits in this study, the instrument of pattern identification for Hwa-byung is meaningful and expected to be applied to the subsequent research. And also, we hope to improve the instrument and make up for this study through various research and discussion.
