The purpose of this study is to investigate daily lives of the intellectually disabled living in residential facilities. The daily time use method that monitors and records 24 hours of the subject was used for the analysis of daily lives of the institutionalized disabled and verbal interaction patterns within each facility. In particular, the analysis focused on 'frequency of activities' and 'lives', with the method of time budget. Based on the activity category table of the 2004 nationwide Time Use Survey, the analysis aimed to identify differences and similarities between the non-disabled and the disabled in terms of daily time use. The interaction pattern analysis method on grounds of the Flanders Category system(1963) indicates the level, the type, and the full details of interaction between the institutionalized disabled and the living rehabilitation teachers. This study is all the more significant in that it monitored the daily lives of the institutionalized disabled for the first time to allow in-depth understanding about the daily lives of the disabled; analyzed interaction patterns between the institutionalized disabled and living rehabilitation teachers; applied time budget study method, a frequently used one in adjacent fields, and therefore should serve as a valuable source material for future studies.

Purpose: The aim of this study was to investigate celiac plexus neurolysis (CPN) for the treatment of cancerous upper abdominal pain in a tertiary university hospital in Korea. Methods: At the tertiary university hospital in Korea, electronic medical records of cancer patients who underwent CPN and died in the hospital from November 2009 to June 2018 were retrospectively analyzed. Results: The total number of subjects was 51. The 17 patients were from the Department of Gastroenterology (33.0%), followed by 11 patients from the Department of Hemato-oncology (21.6%), 11 patients from the Department of Anesthesia and Pain Medicine (21.6%), 9 patients from the Department of General Surgery (17.6%). The diagnosis was pancreatic cancer in 15 patients (29.4%), stomach cancer in 8 patients (15.7%), hepatobiliary cancer in 20 patients (39.2%), colon cancer in 1 patient (2.0%), esophageal cancer in 2 patient (3.9%) and intra-abdominal metastasis in 5 patients (9.8%). The mean survival time after the surgery was 66.4±55.0 days. The pain intensity before and 1 week after the procedure significantly decreased, but the amounts of opioids consumed before and 1 week after the procedure were not statistically significant. Side effects occurred after the procedure including temporary localized pain in 24 patients (47.0%), hypotension in 12 (23.5%), and diarrhea in 6 (11.8%). Conclusion: CPN is an effective and safe procedure for reducing upper abdominal pain caused by cancer, and it is necessary to perform CPN within the appropriate time by establishing a system of interdepartmental cooperation.

Recently, NAND flash memories are used for storage devices because of fast access speed and low-power. However, applications of FTL on low power computing devices lead to heavy workloads which result in a memory requirement and an implementation overhead. Consequently, studies of B+-Tree on embedded devices without the FTL have been proposed. The studies of B+-Tree are optimized for performance of inserting and updating records, considering to disadvantages of the NAND flash memory that it can not support in-place update. However, if a general garbage collection method is applied to the previous studies of B+-Tree, a performance of the B+-Tree is reduced, because it generates a rearrangement of the B+-Tree by changing of page positions on the NAND flash memory. Therefor, we propose a novel garbage collection method which can apply to the B+-Tree based on the NAND flash memory without the FTL. The proposed garbage collection method does not generate a rearrangement of the B+-Tree by using a block information table and a proxy block. We implemented the B+-Tree and ${\mu}$-Tree with the proposed garbage collection on physical devices with the NAND flash memory. In experiment results, the proposed garbage collection scheme compared to greedy algorithm garbage collection scheme increased the number of inserted keys by up to about 73% on B+-Tree and decreased elapsed time of garbage collection by up to about 39% on ${\mu}$-Tree.

Background: To elucidate the relationship between seven occupational dermatoses (ODs) and 20 types of work in Greece. Methods: This was a prevalence epidemiologic study of certain ODs among 4,000 workers employed in 20 types of enterprise, in 104 companies, in 2006-2012, using data from company medical records, questionnaires, occupational medical, and special examinations. The ${\chi}^2$ test was applied to reveal statistically significant relationships between types of enterprises and occurrence of ODs. Results: A high percentage (39.9%) of employees included in the study population suffered from ODs. The highest prevalence rates were noted among hairdressers (of contact dermatitis: 30%), cooks (of contact dermatitis: 29.5%), bitumen workers (of acne: 23.5%), car industry workers (of mechanical injury: 15%), construction workers (of contact urticaria: 29.5%), industrial cleaning workers (of chemical burns: 13%), and farmers (of malignant tumors: 5.5%).We observed several statistical significant correlations between ODs (acute and chronic contact dermatitis, urticaria, mechanical injury, acne, burns, skin cancer) and certain types of enterprises. There was no statistically significant correlation between gender and prevalence of ODs, except for dermatoses caused by mechanical injuries afflicting mainly men [${\chi}^2(1)=13.40$, p < 0.001] and for chronic contact dermatitis [${\chi}^2(1)=5.53$, p=0.019] afflicting mainly women. Conclusion: Prevalence of ODs is high in Greece, contrary to all official reports by the Greek National Institute of Health. There is a need to introduce a nationwide voluntary surveillance system for reporting ODs and to enhance skin protection measures at work.

First, during Jin and Sui dynasty, It is possible that the theory of the contraindications of needling according to whereabouts of the self-guarding energy and demon, affected considerably to the practise of acupuncture and moxibustion, but the detailed situations are unknown. Only, there are some records of the process about circulation of the self-guarding energy and demon by a periodicity of 30 days in the "The prescriptions of Fan-Wang" by Fan-Wang in Jin dynasty and "Hua Tuo Fa" by a nameless person. But the theory differs form the theory of "Huang Di Xia Mo Jing" in some respect. Also, there is the contraindications of needling to abscesses according to whereabouts of the self-guarding energy and demon by every year in the "Liu Juan Zi Gui Yi Fang". but the book has no specific rule in use. Second, during Tang dynasty there were a vasty development on the contraindications of needling according to whereabouts of the self-guarding energy and demon. In the medical works in Tang dynasty, the contents of the contraindications of needling are included in various periodicities and directions such as 12 regions according to the year, 9 regions according to the year, 9 palaces in the body according to the year, whereabouts of the self-guarding energy and demon according the four seasons, every 10 days, every 12 days, every 30 days, and every dozen hours. Also, during Tang dynasty period, the contraindications of needling according to whereabouts of the self-guarding energy and demon were formulated through several adjustments and modifications by many medical scholars. Third, the period between Jin and Tang dynasty, because of historical situations, the documentary data are insufficient in the study of the recommendations and contraindications on the acupuncture, moxibution, and herb medicine according to the specific days and times. And the detailed informations are unknown. Only but once in Tang dynasty the considerable and theoretical adjustments were performed in the "Qian Jin Yao Fang". In Song dynasty, there were also much theoretical fluctuations in the study of the choice of the favorable or the injurious days and times or directions in the acupuncture, moxibustion and the prescription and processing of herbs. Fourth, contraindications on the acupuncture, moxibution, and herb medicine did not include acute and serious disease among the effect province, only include chronic and not serious disease. If the doctors had treated a surgical patients and abscess patients with deeply attached contraindications on the acupuncture, moxibution, and herb medicine, the patients would have became more serious. So the theory was not used for treatment by doctor.

The purpose of this study was to identify the service encounter blueprint by types of restaurants in order to manage moment of truth when customers who visit a restaurant encounter services. The service encounter blueprint gives an overall picture of the service provision to visualize an entire service process and its integrated structure. The blueprint is used for service process analysis technique. The random samples of 15 customers were observed by types of restaurants and the records were collected for three-days' observation. Interviews were performed by 3 managers, 3 service encounter employees, 3 cashiers, 3 cooks and 10 customers by types of restaurants. After drawing the first service blueprint, it was revised by the interview with the 3 managers and 6 service encounter employees. In this paper, restaurant service processes are reviewed and analyzed. By use of service blueprint, the processes are analyzed to find a fail point, customer wait, employee decision. As a result of making a blueprint of service encounter by types of restaurant, blueprints of fine-dining restaurants and family restaurants were similar, while fast-food restaurants showed a little difference. In particular, difference was indicated in a point where interaction of service encounter occurred. Difference was indicated depending on types of restaurants. Therefore, the efforts to improve this problem were needed. The blueprint is a map or flowchart (called a process chart in manufacturing) of all transactions constituting the service delivery process. The results showed that service encounter blueprint can be used to improve the service process in the restaurant's encounter.

Although the 1997 Raw Data of the National Wealth Statistical Survey (South Korea) is timely 20-year-old data, it is meaningful as a benchmarking in the capital stock estimations of Korea, which is estimated by PIM (permanent inventory method). In the case of machinery/equipment, it is the data that can analyze in depth the changes in the industrial structure of Korea. In the case of ASL (average service life) which has economic concept, since the change of ASL is not so large, ASL yielded by the Raw Data of the 1997 National Wealth Statistical Survey is meaningful as reference value for the ASL estimated by the Bank of Korea and the National Statistical Office. As you know Japan has changed its service life due to changes in its industrial structure. However, many of its assets are still used for the years indicated in Showa (before 1989). The same trend with other countries such as Japan. However, the United States is constantly devoted to assessing the useful ASL and value of assets by distinguishing between the Hulten-Wykoff models and those not. Korea has also benchmarked the useful ASL of the United States and Japan when it conducted its own survey every 10 years by due diligence until 1997. In this study, the 'constraint' Iowa curve estimation by the Raw Data of the 1997 National Wealth Statistical Survey is based on the age records of the assets and the maximum age of the assets appropriately derived. And then we made modified Iowa curve by smoothing. From this modified one, we suggested ASL by asset. After 1997, the vintage disposal data directly were collected by the National Statistical Office with Oh Hyun Seung, Cho Jin Hyung, in order to estimate the useful ASL. Since then, the B/S team of the Economic and Statistics Bureau of the Bank of Korea has been working on a new concept of content training.

Malignant ovarian tumors in children are very rare, and consist of about 1 % of all childhood malignant tumors. The purpose of this study is to examine the clinical characteristics, treatment, and prognosis for children with malignant ovarian tumors. We retrospectively reviewed the medical records of children under 15 years of age with malignant ovarian tumors who had been treated surgically at Asan Medical Center between 1989 and March 2009. There were 32 patients, ranged in age at surgery from 2 to 15 years (mean; 10.4 years). The median follow-up period was 64.7 months (from 1 month to 188 months). Pathologic diagnosis were; immature teratoma (n=10), mixed germ cell tumor (n=10), and dysgerminoma (n=6). Tumor stage was classified by the staging system of the International Federation of Gynecology and Obstetrics (FIGO). The number of patients in stage I, II, III, and IV were 24 (75 %), 2 (6.2 %), 4 (12.5 %), and 2 (6.1 %), respectively. The tumor recurred in 4 patients. Seven patients of group 1 did not receive postoperative adjuvant chemotherapy, and in three of them, the tumor recurred. Twenty-five patients (group 2) underwent postoperative adjuvant chemotherapy, and there was only one recurrence. One patient who did not receive postoperative adjuvant chemotherapy and expired 10 months after operation because of tumor recurrence and distant metastasis. The overall 5-year event free survival (EFS) was 84.2 %: group 1 in 44.4 %, and group 2 in 95.7 %. Tumor recurrence was related to the postoperative adjuvant chemotherapy (p=0.004). In conclusion, proper surgical procedures with relevant postoperative adjuvant chemotherapy might improve clinical results in children with malignant ovarian tumors.

The Buma Uprising, which took place in Busan and Masan from 16 to 20 October 1979, was a challenge against the contradictions of the Yushin Regime. Only after 6 days from the insurrection, the 10 26 Accident transpired, in which the then president Park Chung-hee was assassinated, and the Buma Uprising, which acted as the fuse to the shooting, remained as an 'incomplete uprising'. To commensurate with the subject of the paper 'The Truth about Buma Uprising and Historical Reflection', the purpose of this study is to explore how the uprising began, unfolded, and oppressed by comparing it with Busan Uprising and Masan Uprising. It also focuses to discuss, in detail, the effect of the demonstration by college students and the general public and suppression by the forces of the police and military on President Park and his government. This year, we celebrate the 39th anniversary of Buma Uprising, and with all the issues of discovering the truth, restoration of reputation and more, there are decisions and resolves to make including amendment of the legal system. However, there are certain groups of people who act as they led the uprising and mislead and exploit the facts of the events through illegitimate records and testimony, making it impossible to determine the truth. Discovering the truth will require acquisition of objective materials, testimony of those involved in the event and field research as well as imposition of legal and social punishment on those who distorted the truth about the event.
