This study was conducted to develop effective production system in greenhouse for leaves and stems of Angelica acutiloba by using connect pots in 2003 and 2004. Seed germination rate and plant biomass of Angelica acutiloba collected in 2004 were higher than those harvested in 2003. Germination rate of Angelica acutiloba seeds collected in 2003 was 10%, while germination rate of seeds collected in 2004 was above 90%. Especially, plant growth and yield of Angelica acutiloba grown in connect pots sized with 4×4×5cm(length×width×height) were the highest. These results indicate that leaf and stem production of Angelica acutiloba can be improved by using connect pots and optimizing seed collecting time in greenhouse.

Objectives : Major depressive disorder (MDD) causes patients' distress and makes socioeconomic burden, both directly and indirectly. We used the concept of lost productive time (LPT) to estimate the indirect costs and calculated both absenteeism and presenteeism among workers with MDD. Mcthods : Depression group was recruited from workers visiting psychiatric outpatient clinic who had MDD without major physical or mental disorders (N= 106). Age and sex matched healthy control group was also recruited through advertisement (M=100). All participants completed a interview using WHO Health and Work Performance Questionnaire (HPQ), Job Stress Measurement Scale for Korean Employees, and Hamilton Rating Scale for Depression. Statistical analysis was performed with independent t-test or χ² test as characteristics of values (p=0.05). Results : The number of absence (0.94-day/month vs. 0.10-day/month, P=0.015) andthe numberofearly leaving (2.56-day/month vs. 0.24-day/month, P<0.001) were significantly higher in the depression group. Depression group evaluated their Perfor-mance level much lower than controls with significant value (5.16 vs. 7.62, P<0.001). In addition, depression group estimated their performance level during the last 4 weeks lower compared to the level of past 1-year (5.16 vs 6.63, P<0.001). The estimated costs of absenteeism in depression group were higher than controls by 2,520,000 Korean Won per year, and those of presenteeism were also higher by 4,880,000 Korean Won per year. The total costs of LPT in depression group were higher than controls by 7,400,000 Korean Won, which corresponds to 26% ofmean annual salary. In addition, the level of occupational stress, such as high demand and interpersonal conflict, was higher in the depression group. Conclusion : Major depressive disorder costs substantial productivity loss to workers and their company. Presenteeism imposes more time cost than absenteeism. Effectiveness trials are needed to devise cost-effective programs for the early detection and treatment of depression at the workplace.

Laparoendoscopic single-site surgery (LESS) is helpful if not an evidence of suspicious malignancy in huge adnexa tumors. This approach might be reasonable alternative to conventional laparoscopic surgery. We report two cases with LESS for huge cystic adnexal tumors in whole abdomen. A 58 years old multigravida woman in menopause underwent removal of a huge cystic adnexal mass that occupied her entire abdomen by LESS.(ca.5200ml aspiration) A 15 years old single nulligravida woman had a huge cystic adnexal tumor in whole abdomen reaching to the level of the xyphoid process. A needle through the transumbilical single port was inserted directly under the mass. Subsequently, 8000 ml of cystic fluid was aspirated without spillage.

본 연구에서는 데이터 마이닝 기법을 활용하여 한국 프로야구의 승패예측모형을 구축하는 실험을 진행하였다. 이를 위해, 2017년에 실시된 한국 프로야구 10개 구단의 전체 경기 중 무승부 경기를 제외한 1,418경기에 대한 자료를 사용하였다. 승패예측모형에는 의사결정나무, 베이즈넷, 인공신경망 알고리즘과 앙상블 기법인 배깅과 부스팅이 사용되었으며, 그 결과 배깅 기법에 인공신경망을 적용한 예측모형에서 가장 높은 예측률인 85.18%를 기록하였다. 다음으로 의사결정나무 기반 예측모형을 활용하여 한국 프로야구 전체 구단에 관한 8개의 승패규칙을 도출하였다. 여기에서 승패규칙은 승패예측에 영향을 미치는 주요 요인들인 팀출루율, 팀타율, 피안타, 안타, 타석, 타수로 표현되며, 도출된 규칙을 바탕으로 구단의 승률 향상에 도움을 주는 전략을 제안하였다. 또한 플레이오프 진출 구단과 미진출 구단에 관한 승리규칙을 각각 4개씩 도출하였고 이를 바탕으로 두 집단에 맞춤화된 승률 향상 전략을 제시하였으며, 실제 구단에서 선수를 영입한 방향과의 비교를 통해 제시된 전략의 활용 가능성을 확인하였다. This study conducted an experiment to develop win-loss prediction models for the Korean professional baseball league using data mining techniques. To this end, we used data on 1,418 games from all games played by the ten Korean professional baseball teams in 2017, except draw games. We developed win-loss prediction models using not only a decision tree, Bayse net, and artificial neural network algorithms, but also ensemble methods, such as bagging and boosting. As a result, first, we found that the artificial neural network-based prediction model using the bagging method reported the best accuracy (85.18%). Second, we derived eight win-loss rules for entire teams from the decision tree-based prediction model. These rules consist of six influential factors: team on base average, team batting average, hit by opponent, hit, plate appearances, and at bat. Using the derived rules, we proposed helpful strategies for improving the winning rate. Third, we derived four winning rules for both playoff teams and non-playoff teams; using the rules we proposed customized strategies for improving the winning rate of the two different groups. Finally, we confirmed the feasibility of the proposed strategies by comparing non-playoff teams’ actual player recruitment strategies.

Schwann cells(SCs), an important component of the peripheral nervous system, intract with nerous to mutually support growth and replication for the peripheral nerve regentation. Recently, ading SCs to the lumen of guidance channel is widely tried to improve regeneration or to make regeneration possible over otherwise irreparable gaps. however, it is not easy to isolate and multiplicate SCs as much as enough to help the axonal regeneration. For the allogeneic SCs source for tubular nerve guidance, we developed a little bit improved technique of harvesting and multiplicating SCs. by culturing dispersed dorsal root ganglia in specially designed medium with growth factors and serial processing, we repeatedlly generate relatively homogenous SC cultures. Our technique was compared with other methods of literature using immunostaining methods such as GFAP, S100, BDNF and the total SC count assessment at different time interval after primary culture.

The primary surgical objective in treatment of burn wound is to eliminate the damaged tissue and close the wound promptly so that the septic, metabolic, and functional effects that accompany an open colonized wounds will be avoided. It is difficult to apply this principle to deep and extensive burns, however, because of delays imposed by a physiologic-limit to the area of eschar that can be safely excised at one operation and because of lack of sufficient unburned donor sites to provide closure of the wounds with autograft. The mesh grafts in which skin could be stretched from 1½times to 9 times its original size have been made to obtain maximum coverage from minimal donor sites, but the pain and oozing can not be controlled until the epithelization covers the raw surfaces of the meshed graft. These problems have stimmulated the search for the biological dressings with amniotic membrane on mesh graft that simulate partial thickness burn, which provide comparable beneficial local and general physiologic effects. In our personal experience of eight cases, this form of treatment of deep and extensive burns has proved the more effective and practical method.

This study aims to investigate educational uses through smart education and SNS and seek ways to incorporate them into physical education (PE) classes. Modern society has brought changes regarding communication, formation of relationships, and life styles due to information technology development and the wide spread of smartphones. In the center, there is Social Network Service (SNS) through which the uses and values are gradually increasing around the world. This social changes also brought about smart education in school education for the needs of diverse educational demand. Smart education redefined educational systems in terms of contents, methods, evaluation, environment, etc. by effectively utilizing it into school education because it overcomes the environmental and physical limitations using network resources based on information technology. It is changing educational paradigms in the 21st century which seeks to develop and foster students' abilities so that every student is able to study according to their level and become a global leader. The results of the study on ways to activate PE classes through smart education and SNS showed the following. First, smart education in PE classes is the challenge that needs to be applied in future educational methods. Second, smart education and SNS-based instructions introduced a new learning environment and broadened PE classes. Third, smart education and SNS-based instructions show some educational effects of developing social skills through students' academic achievement, satisfaction in classes, interest, self-esteem, and cooperative learning. Fourth, it is essential to develop a variety of contents to apply to PE classes. Fifth, it is necessary to educate teachers about smart education and the uses of SNS.
