Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

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.

Objective To evaluate the long-term outcomes, including the pregnancy outcome and recurrence rate after single-port laparoscopic myomectomy (LM) using a modified suture technique with a Hem-o-lok clip (Choi’s LM) and conventional 4-port LM. Methods A retrospective study of patients who underwent Choi’s LM (n=55) and 4-port LM (n=102) in a single institutional hospital was conducted. Patients with <3 symptomatic myomas sized <10 cm each and operated on by a single surgeon were included. Recurrence was confirmed when a myoma measuring ≥3 cm was detected. Results The patients in both groups had similar demographic characteristics. Single (76.4% vs. 62.7%) and intramural (52.7% vs. 56.9%) tumors were commonly detected in both groups in the mean diameter (6.8±1.5 cm vs. 7.0±1.6 cm; P=0.40). In Choi’s LM, 16 patients (29.1%) needed an additional port; those who were nulliparous and/or had a large leiomyoma more frequently required an additional port (P=0.023 and 0.04, respectively). During a median follow-up period of 69 months, 17 patients (7.1% vs. 14.6%) had recurrence. The size of dominant myomas at recurrence was significantly smaller in patients who underwent Choi’s LM (3.4±0.7 cm vs. 5.7±2.4 cm; P=0.004). All 13 patients in both groups who successfully conceived had a full-term delivery. No major complications occurred during pregnancy. Conclusion Although an additional port was frequently used, the long-term outcomes of patients who experienced recurrence and pregnancy after Choi’s LM were acceptable. Considering its usability, Choi’s LM is feasible for the treatment of uterine leiomyoma.

본 연구는 온실의 난방 에너지 절감을 목적으로 온실 내부에 알루미늄 온수배관을 설치하여 난방효과에 대한 기초자료를 구축하고자 수행되었다. 그 연구결과를 요약하면 다음과 같다. 전체 실험을 포함하여 온실내의 높이별 온도편차는 4.0~7.0℃ 정도의 범위로서 그 차이가 크게 나타났다. 팬코일유니트(FCU)를 작동시킨 경우가 작동시키지 않은 경우에 비해 유출입수의 온도차가 3.3℃ 정도 크고, 소비전력량은 36.2~40.1% 정도 증가하였으며, 시간당 방열량은 44.6~52.0% 정도 증가하는 것으로 나타났다. 실험기간동안 순환유량은 0.48~0.49L · s<SUP>?1</SUP> 정도의 범위에 있었고, 평균유속은 1.53~1.56m · s<SUP>?1</SUP> 정도였다. 유출입수의 평균 온도차는 6.24~11.50℃이었다. 최저 외기온 ?14.0~?0.6℃ 범위에서 설정온도별 방열량은 135,930~307,150㎉ 정도의 범위로서 시간당 9,610~19,630㎉ · h<SUP>?1</SUP> 정도의 범위에 있었다. 이것은 최대난방부하의 약 23~53% 정도의 난방에너지를 공급할 수 있을 것으로 나타났다. 전체 방열량과 소비전력량은 각각 2,548,306㎉ 및 3,075.7㎾h이다. 화석연료인 경유로 난방할 경우, 소요되는 경유의 총 소비량은 281.6L 정도이고 비용은 321,000won인 것으로 나타났다. 농가용 전력요금을 적용하면 전력사용에 대한 총비용은 110,730won 정도로서 경유 소비 비용의 33.5% 정도로 나타났다. 실험구의 온도가 대조구보다 약 8.3~14.6℃ 정도 높게 나타났다. This research was conducted to obtain basic data with regard to the heating performance that would be produced by installing an aluminum hot water pipe inside the greenhouse with the goal of reducing the heating energy in greenhouse. The research results are summarized as follows. The degree of difference in relation to the temperature by height within the greenhouse during the entire experiment was significant - within the range of 4.0~7.0℃. The temperature difference between incoming and outgoing water was about 3.3℃ greater when FCU was activated compared to when it was not activated. Meanwhile, the amount of energy consumed increased about 36.2~40.1%. The amount of pyrexia per hour also increased by 44.6~52.0%. During the experiment period, circulated flux was within the range of 0.48~0.49 L · s<SUP>?1</SUP> while average fluid speed was 1.53~1.56 m · s<SUP>?1</SUP>. The average temperature difference between incoming and outgoing water was 6.24~11.50℃. The amount of heating value by each set temperature within the minimum outdoor temperature range of ?14.0~?0.6℃ was 135,930~307,150 ㎉, and the range was within the 9,610~19,630 ㎉ · h<SUP>?1</SUP> per hour. This demonstrated that about 23~53% heating energy of the maximum heating load could be supplied. Total radiating value and amount of energy consumed were 2,548,306 ㎉ and 3,075.7 ㎾h, respectively. When heating takes place using oil, which is a fossil fuel, the total amount of light oil consumed was 281.6 L while the cost was 321,000 won. When the electricity cost for farms is applied, the total cost was about 110,730 won, which is about 33.5% of the cost required compared to oil consumption. The temperature at in the experiment area was about 8.3~14.6℃ higher compared to that of the control area.

최교원,김태균 東新大學校 2002 論文集 Vol.12 No.-

The purpose of this study is to find the situations and problems of performance appraisal system in korean corporations, and to improve the problems of system. The study method was used by method of literature review. The references of study were included the survey data and eight corporation's performance appraisal data (4 cases were those of Korean corporations, and others were those of American/Japanese corporations). The finding problems of performance appraisal system in Korean corporations are as follows: 1) Application limitation of performance appraisal results, it could not be useful tools for developing the employee's performance ability and improving the achievements in their company. 2) Current performance appraisal system was turned out as low incentive system, incurring low productivity and weakness of international competitiveness. 3) The system was majorly used as only control tools of employees. 4) The system was founded not effective tools for employee's accurate performance ability or achievements, but was used as forced assignment method. 5) The results did not open for employees. Thus, the employees couldn't be reliable the objectivity and accuracy of the results. 6) Training for appraisors or development of appraisal skills was not executed. It's problem was liable to be lack of objective or accurate appraisal ability or skills. 7) The performance appraisal tools are considerably abstract or extremely comprehensive. To improve the above problems of performance appraisals, the following recommendations should be accomplished in Korean corporations. 1) Understanding of performance appraisals should turn around toward application of essential informations to decide the employees wages. 2) The results of appraisals should be opened. 3) Appraisals by the purposes should be implemented, not by the uniformity. 4) Absolute appraisals, not relative appraisals by forced assignment method, should be employed to evaluate the accurate job performance ability or output. 5) Opportunity for participating by employees should be enlarged. 6) Training or skill education for appraisors should be strengthened to gurantee the objective and accurate appraisals.

要約표고폐골목의 재활용을 목적으로 폐골목과 정상재의 칩을 일정비율로 혼합하여 얻은 목질보드의 성질을 조사, 검토하였다. 그 결과 폐골목의 목섬유는 정상재보다 다소 짧고 표 면이 거칠었으며 폐골목 변재부의 밀도는 정상재에 비해 상당히 낮았다. 파티클보드의 두께 팽윤율 및 파괴계수의 시험결과 폐골목을 25~50% 정도 혼합한 경우는 정상재와 비슷한 값 을 나타냈다.결론적으로 폐골목은 파티클보드의 재료로 사용될 수 있고 정상재와의 혼합비율은 25~50% 범위에서 조정되어야 할 것으로 생각되었다.ABSTRACTTo provide further information for reutilization of the bed-logs decayed by oak mushroomfLentinus edodes), the properties of wood-based board prepared with mixed materials of normal wood and bed-logs were examined.Wood fibers in bed-logs showed different morphology from normal wood fibers, that is, shorter length and rough surface. Thickness swelling increased with increasing mixing ratio of bed-log. On the other hand, modulus of rupture(MOR) in bending strength decreased. In products, the visual surface of board prepared from higher mixing rate of bed-log chips was smooth.Consquently, it is considered that the optimum mixing rate of bed-log to normal wood is the range of 25-50% and the bed-log can be used for raw material of board instead of normal wood.

Background : The advances in surgical techniques and stabilizing devices have made the off-pump coronary artery bypass (OPCAB) popular, and good results have been published. We analyzed the early results of OPCAB performed in our hospital. Materials and Methods : Between January 2004 and December 2004, 23 patients underwent OPCAB. There were 14males and 9 females with mean age of 62.6± 10.3years. Preoperative diagnoses were unstable angina in 13(57%), acute myocardial infarction in 9(39%), and stable angina in 1(4%). Preoperative angiographic diagnoses were three-vessel disease in 12 (52%), two-vessel disease in 8(35%), one-vessel disease in 1(4%), and left main disease in 2(9%). Results : The mean number of grafts was 2.6 ±0.9 per patient. Vessels accessed were left anterior descending artery in 23, diagonal branch in 14, obtuse marginal branch in 9, right coronary artery in 12, and posterior descending artery in 1. Left internal mammary artery were used in 22 patients and bilateral internal mammary arteries were used in 1 patient. There was no operative mortality. Postoperative complications were cerebral vascular accident in 1, postoperative bleeding which required operative management in 2, arrhythmia including atrial fibrillation in 5, and minor operative wound problem in 1. Pre-discharge graft patency was evaluated in 11 patients. One internal mammary artery graft was occluded in 11 internal mammary artery graft evaluated. The patency rate was 91%. Seventeen saphenous vein grafts were patent in 19 saphenous vein grafts and the patency rate was 89%. Conclusion : Our result of OPCAB is promising and OPCAB is suggested to be the ideal technique with less morbidity and mortality.
