This study investigated the actual condition of book numbers in South Korean academic libraries. Book numbers that are used in the Korean academic libraries consist of a combination of author-number or author-name, the first letter of the title, and any other shelflisting device. This study examined the current problems that perceive academic librarians on book numbers and the problem awareness of librarians who are working at 110 academic libraries in South Korea. The result shows that academic libraries are using eleven different methods of the book numbers table including nine eastern methods and two western methods. Also, librarians mentioned that the crucial concerns among participating libraries were the duplication of the book numbers and ineffective collection management. Therefore, this study suggested the expansion of the book numbers system in order not to duplicate of book numbers and the unification of western and eastern methods so that academic libraries tackle problems of ineffective collection management.

The tunnel type spillways is under construction to increasing water reservoir capacity in Dae-am dam. Cutting-slope adjacent to outlet of spillways had been originally designed to be 63 degrees and about 65m in height. Examination is carried out in preceding construction that it is caused to some problems possibility which of machine for slope cutting couldn't approach to the site, blasting for cutting slope might have negative influence on highway and roads nearby, and fine view along the Tae-hwa river would be eliminated. In order to establish stability of tunnel and more friendly natural environment that we are carry out detailed geological surface survey and analysis of slope stability. So, we are design and construct for tunnel excavation with possible method that it is keep up natural slope. The result of survey and analysis that natural slope was divided 3 zone(A, B, C zone). In A and B zone, in first removed floating rock, high tensile tension net is install that it prevent of release and falling of rock, in order to security during under working. In addition to, pre-stressed rock anchor is install purpose of security during tunnel excavation because of fault zone near vertical developed above excavation level. Zone C is relatively good condition of ground, design is only carry out random rock bolt. All zone are designed and constructed drainage hole for groundwater and surface water is easily drain. Desinged slpoe is harmony with near natural environment. Successfully, construction is completed.

To identify health behavior of Peptic ulcer patients among all employees in Korea and examine relevant factors to present basic data for improving Korean adult employees' health conditions and quality of living, 3,515 employees aged 20 to 69 were sampled from the group that responded to the question concerning the presence of Peptic ulcer in the fourth Korea National Health and Nutrition Examination Survey for the third year (2009). After logistic regression analysis was carried out to see the effects of working conditions, harmful factors, shift work, stress perception, and experience of depression on the presence of Peptic ulcer, it was found that unsafe or unpleasant working conditions led to higher risk of getting Peptic ulcer, that flexible workers were more likely to get Peptic ulcer, and that depression or stress perception exerted almost no effect on Peptic ulcer. With the increase in the number of flexible workers, increasingly more interest is taken in the effects of shift work on health; occupational Peptic ulcer tends to become chronic as compared with the condition in the general population and reappear even after recovery in many cases; therefore, it is necessary to take special management measures by estimating the number of those at a risk of getting Peptic ulcer and by finding out its risk factors.

Objective: The goal of this study was to assess work ability of Korean workers in the shipbuilding industry. Background: Old age is associated with inevitable time-dependent losses in physical capabilities. However the maintenance of physical capabilities is essential for continuing independence in old age. The work ability index(WAI) was constructed to reveal how well a worker is able to perform his or her work. Method: The WAI is a kind of survey methods developed to estimate the work capacity of aged workers by the Finish Institute of Occupational Health(FIOH) in 1998. The difference of the WAI between groups in each category was tested using the Kruskal-Wallis test, and the relationship between the WAI and the workers' ages was tested by the Correlation test. Results: This study surveyed 2,709 persons working in the shipbuilding industry in Korea. The average WAI score for all workers was 40.0 denoting a Good Level. Also, workers in the shipbuilding industry had lower work ability, as compared to the results of other industries. The WAI was analyzed for different age groups(${\leq}29$; 30~34; 35~39; 40~44; 45~49; 50~54; ${\geq}55$). The results of Kruskal-Wallis test showed that significant difference was identified on the effect of aging(p<0.05). Conclusion: Advanced countries like the Finland showed decreasing tendency in good and excellent levels as aged, but there was no decreasing tendency in Korean population. The results may be attributable to the general characteristics of Korean society, such as poor social security and burden caused by role of the patriarch. It may bring forth higher work ability in aged population even their physical condition is getting worse. Application: This finding could be used for developing more accurate assessment tool of work ability for working environment.

Objectives: The objective of the study was to resolve various elements of conflict by presenting the results of the study and to help build an enhanced oriental medical service system. Methods: The researcher collected data from 12/15/2006 to 1/31/2007. A total of 1000 questionnaires were sent out to oriental medical doctors working at oriental medical facilities and the 15% (150 questionnaires) of them that were returned completed were analyzed. Results: 1. As to the proper proportion of oriental medical doctors to western medical doctors, they said it should be less than 20%. About separating the task of prescribing oriental medicine (herb) from oriental medical treatment, 80.7% of them were against it. 98.7% said oriental medical doctors needed the control of medical technicians. 2. 72.3% said they had no intention of taking the U.S. NCCAOM board to practice oriental medicine overseas. A majority (57.7%) were in favor of unifying oriental medical license with western medical license. 3. Oriental medical doctors had greater job satisfaction [than all oriental medical doctors number]. If they were to choose another occupation than oriental medicine they would consider becoming a research fellow above all other occupations. If they were to reenter college, they said they would probably choose oriental medical school. However, the choice of reentering oriental medical school was lower than that of western medical school. Conclusion: This study has also statistically determined the current issues that may pose conflicting views on the part of the respondents. A periodic study such as this one will hopefully aid in establishing policies for oriental medicine.

This study investigated the influence factors of retirement expectations among medical technologists at medical centers in Seoul and Gyeonggi area, Korea. Subjects were 158 medical technologists. Using a sampling survey method, data was analyzed between July 2015 and December 2016. There was a negative correlation between educational level and economic preparation, but gender and monthly income did not reach retirement expectation level. Conversely, we found no change in the trends with respect to gender, monthly income; nonetheless, we observed that frustration gradually increased with age and working duration. In conclusion, our findings show that there are four factors that significantly influence retirement expectation and preparation: age, level of education, working duration, and family condition. This study contributes to understanding retirement expectations and can be a reference for retirement preparation in medical technologists.
