R&D strategies of companies with low and high technological levels are discussed based on the concept of technology convergence and divergence. However, empirically detecting enterprise technology convergence in the distribution of enterprise technology (total productivity increase) over time and identifying key change factors are challenging. This study used a novel statistical indicator that captures the internal technology distribution change with a single number to clearly measure the technology distribution peak as a change in critical bandwidth for enterprise technology convergence and presented it as evidence of each technology convergence or divergence. Furthermore, this study applied the quantitative technology convergence identification method. Technology convergence appeared from the separation of total corporate productivity distribution of 69 IT companies in Korea in 2019-2020 rather than in 2015-2016. Results indicated that when the total technological level was separated from the technology leading and technology catch-up, IT companies were found to be pursuing R&D strategies for technology catch-up.
A study was carried out from October 1977 to September 1978 in order to develope health care delively system which will meet to rural area in Korea. For the study objective a model of health care delivery system of Myun (township) area was developed which is adopted the net-work of village health voluntary worker who will play the role of bridge for communication related with health and illness between families or village people and health subcenter, and :he model health care delivery system net-work was set in the area of Soodong Myun, Yangju Gun. which is the rural health demonstration area of Ewha Womans University since 1972. The activities and attitude of 22 village health voluntary workers were observed and analized. during the study period. The results are as follows; 1. For the field activities of village health voluntary workers. a guide line which is described with specific behavioral objectives was developed and used for not only training of the workers but also evaluation of their field activities. 2. During the study period, the number of 971 village people were served primary health care service by village health voluntary worker and the service was classified largely into symptomatic medications (92%) and preventive measures (8%). 3. Comparative percentage of the number of 894 symptomatic cases cared by village health voluntary workers to 5,695 cases of patient treated by Soodong Health Subcenter during the same period was 15.7%. 4. Annual utility rate of village health voluntary worker by Myun total people was 16.1% but utility rate by Rie was varied from 38.2% to 2.8% which shown there were considerable differences in each Rie. In order to settle the village health care service, the obstructive factors of utility should be detected and their counter measure must be taken. 5. As the health need of village people increases, it is expected that the supplement of drug excluding present sit basic drugs is inevitable, but considering the ability of village health voluntary worker, the selection of additional drugs and education, plan should be carefully studied. 6. It is desirable that a financial resource for supplementary purchase of first aid kit, drugs and materials whould be alloted from village public fund like Saemaeul Women's Club fund, which has already practiced in a few villages in the study area. 7. As pointed out by village health voluntary workers, in order to improve the village health, village leaders should be in the center of it and the cooperation of whole village people is a core of healthful village development, and it is reasonable that the health subcenter backs up these voluntary health activities by village people in techniques. 8. It seems effective that a supplementary education for village health voluntary worker be accomplished by a planned education through regular meetings like worker's monthly meeting and irregular post guide when Myun Health Workers can handle the problems found during the round trip of villages. 9. It is desirable that village health voluntary workers, who are recommended by a civil voluntary organization like Saemael Woman's Club, are charged by natural villagc unit, are given a function of village health care service and used through basic education at health subcenter. 10. It is advisable that the village health voluntary worker's service is compensated not by a form of money, but by other way such as an exemption of medical fee of worker herself or her families in health subcenter can be one method. 11. Daily health activities of each village health voluntary worker should be reported to health subcenter by biweekly or monthly in order to get not only for basic data of the program but also for evaluation the program. It is recomandable that the report form should be simple and clear enough for village health voluntary worker to fill it effectively. 12. Village health care service should be developed into a Saemaeul Movement in which village people actively participate. For this, the appointed function of village health voluntary worker should be absorbed into those of living Environment Betterment Section or Family Planning Section of Saemaeul Women's Club or it is desirable that establish a new section, Village Health Promoting Section and make it involve the appointed functions of those sections mentioned above.
Breast cancer is the most common malignancy and also the second leading cause of cancer death among women and also in women that have a high mortality. Previous studies showed that magnesium (Mg) has cytotoxic effects on malignant cell lines. However, the anti-cancer effects of Mg on MCF-7 breast cancer cells are uncertain. This study was aimed at the comparison of the cytotoxic effect of Mg salt (MgCl2) and cisplatin on MCF-7 cells and fibroblasts (as normal cells). After treatment with various concentrations of MgCl2, and cisplatin as a positive control for 24 and 48 hours (h), cytotoxicity activity was measured by MTT assay. In addition, apoptosis was determined by annexin V/propidium iide assay. Both cisplatin and the MgCl2 exhibited dose-dependent cytotoxic effects in the MCF-7 cell line, although the LD50 of the Mg was significantly higher when compared to cispaltin ($40{\mu}g/ml$ vs. $20{\mu}g/ml$). Regarding annexin V/propidium results, treatment of MCF-7 cells with LD50 concentrations of cisplatin and Mg showed 59% and 44% apoptosis at 24h, respectively. Finally, the results indicated that Mg has cytotoxic effects on MCF-7 cells, but less than cisplatin as a conventional chemotherapeutic agent. However, regarding the side effects of chemotherapy drugs, it seems that Mg can be considered as a supplement for the treatment of breast cancer.
Purpose: This study was conducted to analyze occupational and leisure-time physical activity(LTPA) in male office workers and to examine factors related to LTPA. Method: The subjects for this study were 226 male office workers, from eight work places located in Seoul, who had no physical restrictions. Minnesota LPTA Questionnaire (Taylor et al., 1978) revised by Kim(1997) was used to measure LTPA and revised Tecumseh Occupational Physical Activity Questionnaire (Motoye, 1971) was used to measure occupational physical activity. The data were collected from May 4 to May 19, 2001 using a semi-structured questionnaire with interviews and self reports. The collected data were analyzed using SPSS Windows 10.0 Program. Results: The results of this study are summarized as follows. 1. The mean level of physical activity was 8,716.9kcal/wk. The occupational physical activity was at 6,605kcal/wk(75.8%) and the level of LTPA was 2,111.4kcal/wk (24.2%). 2. Using 2,000kcal/wk as a base for categorizing LTPA as active or inactive, it was found that there were 94 subjects(41.6%) in the active group. 3. Subjects in their thirties had a lower level of LTPA than subjects in other age groups (F=3.484, p<.05). Physical activity, self-efficacy (r=.405, p=.000) and perceived health status (r=.301, p=.000) were positively related to LTPA. 4. Participants in club activities had a higher level of LTPA than those who did not (t=-2.369, p=.020). Support for physical activity(r=.164, p=0.13) was positively related to LTPA. Conclusion: This study suggested that to increase physical activity in male office workers, physical activity promotion programs should be established according to age and sex especially for those who are in their thirties and for women, and should include strategies strengthening support through peer groups and family, developing club activities and increasing physical activity self-efficacy.

Only 1.1% of patients considered it as having hereditary components. 13) 51% of patients were slow in caring for their own illnesses. They started to reat epilepsy after spending 5 years of time from the initial seizure. Only 5.4% of patients had received the modern anti-epileptic therapy right after the nitial seizure. 14) 62.1% of patients had no therapy or irregular or incomplete treatment before registration at the Rose Club Clinic. 15) Before registration at the Rose Club, 42.4% of patients received medical care. On the other hand, 25.6% went to herb doctors and 12.5% used to go to the drugstore in order to get anti-epileptic drugs. 16) 41. 6% of patients who took anti-epileptic drugs had more or less side-effects. Indigestion was the most common. 17) For continuation of treatment, 30.3% have received treatment for more than 5 years and the evident showed that epilepsy took a longer time to be cured. 18) Regarding the medical care received 44.2% of patients were very satisfied with effective care and 26.5% felt as good. 19) For attitudes toward epilepsy. 27.0% of patients and 68.2% of patients family were pessimistic. 20) 65.9% of patients had optimistic attitudes toward effectiveness of medical care of epilepsy. 21) 64.8% of wives and husbands had better understanding and cooperative for their spouses who had epilepsy. 22) 33.3% of patients were under-treated at the place of work. 23) 70.2% of patients wished to marry when they reach childbearing age and 63% wished to have children. Through the above results it is recommended for nation-wide epilepsy control that the sound and correct health education not only from health aspect but also from welfare aspect should be planned and implemented as soon as possible.
Purpose: The purpose of this study was to identify factors affecting health promotion behavior among workers with high risk of metabolic syndrome. This study was based on the planned behavior theory. Methods: The participants were 167 workers at high risk of metabolic syndrome. Data were collected using a structured questionnaire. Surveyed variables were attitude, subjective norm, perceived behavioral control, intention, and health promotion behavior. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and hierarchical regression analysis with SPSS/WIN 22.0. Results: Perceived behavioral control affected the intention of health promotion behavior among the workers with high risk of metabolic syndrome. It explained 62% of variance in the intention of health promotion behavior (F=40.09, p<.001). Perceived behavioral control and occupation affected health promotion behavior among the risk workers with high risk of metabolic syndrome. The two factors explained 16% of variance in health promotion behavior (F=4.95, p<.001). Conclusion: The findings of this study suggest that perceived behavioral control is the only factor affecting health promotion behavior when the theory of planned behavior was applied. Therefore, intervention programs for improving health promotion behavior should be focused on strengthening perceived behavioral control.
