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.

이 연구는 국내 남자프로배구경기에서 나타난 서브리시브에 따른 팀간 공격 차이를 서브리시브의 유효성, 세터/비세터에 의한 세트, 세터의 위치, 공격형태, 공격결과를 기반으로 어떠한 차이가 있는지를 알아보기 위하여 NH농협 2009~2010 V리그 남자프로배구경기 126경기를 대상으로 하였다. 분석된 요인들을 기반으로 팀간 공격형태별 빈도, 대전팀간 교차분석, 공격형태별 성공 비율 차이를 분석하여 다음과 같이 나타났다. 첫째, 요인에 따른 공격형태별 빈도를 분석한 결과, 서브리시브가 성공하였을 경우 7개팀 중 5개팀이 속공공격, 실패하였을 경우 7개팀 모두가 오픈공격의 빈도가 높게 나타났다. 둘째, 요인에 따른 대전팀 교차분석의 차이를 검증해 본 결과 차이가 나타났다. 시즌 1위팀인 S팀은 7위팀인 A팀보다 서브리시브 성공률에서 10%이상의 차이가 나타났으며, 서브리시브의 성공·실패와 상관없이 7개팀 모두 96%이상의 세트가 세터에 의해 이루어지는 것으로 나타났다. 또한, 공격결과 성공률 평균에서는 상위팀인 S팀·H팀(56.9%), 중위팀인 D팀·L팀(54.7%), 하위팀인 W팀·K팀·A팀(47.7%)로 나타나 상위팀일수록 더 높은 공격결과 성공률 평균이 나타났다. 셋째, 공격형태별 성공 비율 차이를 분석한 결과, 이동공격을 제외한 모든 공격형태에서 차이가 나타났다. 오픈공격에서는 S팀이 D팀은 제외한 모든 팀보다 높은 오픈공격 성공 비율의 차이가 나타났으며, A팀은 W팀을 제외한 모든 팀에게 높은 오픈공격 성공 비율의 차이를 나타내주는 특징을 보였다. 시간차공격에서는 K팀이 A팀을 제외한 모든 팀에게 높은 시간차공격 성공 비율의 차이를 나타내주었으며, 속공공격에서는 H팀이 D팀을 제외한 모든 팀에게 높은 속공공격 성공 비율의 차이가 나타났다. 후위공격에서는 하위팀인 W팀·K팀·A팀에서 상위팀들에게 높은 후위공격의 성공 비율의 차이를 나타내주는 특징을 보였다. 퀵오픈공격에서는 A팀이 K팀은 제외한 모든 팀에게 높은 퀵오픈공격 성공 비율을 나타내주는 특징을 보였다. 서브리시브에 따른 팀 간 공격에서 서브리시브의 유효성, 세터/비세터에 의한 세트, 세터의 위치, 공격형태, 공격결과에 따라 팀 간 차이가 나타났다. 안정된 서브리시브와 세트는 여러 공격형태와 높은 공격성공률과의 관계가 매우 높다고 볼 수 있다. 대부분의 기록에서 승리한 팀이 패배한 팀보다, 시즌 순위 기록으로 상위팀이 하위팀보다 우위를 나타내 여러 요인들의 안정 및 높은 성공률을 위하여 꾸준한 연습과 대전팀의 경기기록에 대한 연구가 필요하다. The study was to compare the differences of attacking patterns related to serve receives basing on effectiveness of serve receives, setter/non-setter, location of setter, type of attacks and outcomes of attacks. The subjects were 126 games in 2009~2010 Korean NH Nonghyub V-league men`s championships. The analysed factors were considered on frequencies of type of attacks by each team, cross comparisons between teams played and a ratio of successful outcome by the type of attacks. The results were found as following belows; Firstly, in the comparisons of frequencies on the type of attacks, 5 teams among 7 teams shown greater frequencies on counter-attacks while the teams were winning. Secondly, there were significant differences of types of attacks between teams. The championships` winner, team S was greater than other teams about 10 % of successful serve-receives and 96% of sets were done by setter without the relationships of successful or unsuccessful serve-receives. Also, the successful percentage of attacking outcomes were ordered by ranks such as superior team S and H (56.9%), mid-ranks team D and L (54.7%) and inferior team W, K and A (47.7%). Thirdly, in the comparisons of successful ratio of type of attacks, there were significant differences between the type of attacks except moving-attacks. In the open-attacks, the ratio by team S was greater than team D. In addition, there was significant difference on the ratio by team A excepted the comparing with team W. In the time difference attacks, the ratio by team K was different comparing to other teams excepting team A. In the counter-attacks, team H were greater ratio excepting to team D. In the backward-attacks, the inferior teams (W, K and A) made greater successful ratio of attacks against the superior teams. In the quick-attacks, there was grater ratio by team A against others excepted to team K. There were differences of the effectiveness of serve-receives, sets by setter/ non-setter, location of setter, type of attacks and outcome of attacks depending on the teams. The stable serve-receives and sets were highly relevant to the various types of attacks and greater ratio of successful attacks. The continuous practice and study on oppositional data are required in order to enhance their performances because the winning and superior teams were stable ratio of successful attacks rather than the losing and inferior teams.

We carried out a study on phytoplankton community at Owon stream, Jeollabukdo, Korea. The author have examined 83 taxa of the phytoplankton from researched area. These were composed of 5 classes, 11 orders, 21 families, 44 genera, 79 species, and 9 varieties. The composition of occurrence species were as follows: green algae are 48.2%, diatoms are 33.7%, blue green algae are 10.8% and etc(7.3%). Dominant species were Chlamydomonas angulosa, Pandorina morum, Coelastrum microporum, Scenedesmus quadricauda, Staurastrum gracile, Melosira varians, Me. italica, Synedra ulna, Sy. acus, Cocconeis placentula, and Cymbella tumida. The standing crops varied from 1,650cells/ℓ to 47,000cells/ℓ. Phytoplankton density of Owon stream were lower about 8.6 times to a 1,531 times than those of other lakes and rivers in Korea. So, to preserve the water quality in Owon stream we have to manage continuously on the nitrogen and phosphorus.

Background and Objectives : Palindromic rheumatism (PR) is known to be triggered without any obviously inciting events in most patients, although, in a few cases, attacks have been noted to relate to another events such as weather change, childbirth, ingestion of certain foods, or over-exercise. The aim of this study was to characterize the triggering factors on palindromic attacks. Materials and Methods : We evaluated sixty-four patients with PR for the presence of triggering factors and the relationship between attacks and triggering factors by interview of patients. We considered that there was an probable association between episodes and PR, if episodes within 24 hours prior to PR had triggered at least 50% of all attacks and a definite association between episodes and PR, if episodes within 24 hours prior to PR had triggered 100% of all attacks. Results : In 15 patients (35.9%), there was a possible association between episodes of PR and initiating events. In 8 patients (12.5%), there was a definite association between episodes of PR and initiating events. The triggering factors were physical over-activity including exercise (19/64: 29.7%), foods, such as rawfish, crab, and chicken, including alcohol (19/96: 19.8%). However, there were no difference between the groups with and without the triggering factor in sex ratio, duration and onset of PR, the positive rate of rheumatoid factor and involved sites. Conclusion : Our observations showed that PR was triggered by physical over-activity more than in previous reports and hypersensitivity to foods was a causative factor in some patients with PR. However, patients with triggering factors had a similiar clinical profile to patients without triggering factors.

On filtrated and autoclaved water samples from Lake Jinyang, algal growth potential(AGP) test using Selenastrum capricornutum Printz were performed from February, 1999 to October, 1999 in order to assess fertility potential of the lake and to identify possible limiting nutrients. Algal growth potentials of the filtrated and filtrated after autoclaved samples were 0.018 ㎎/ℓ ~9.965 ㎎/ℓ and 0.018 ㎎/ℓ ~28.788㎎/ℓ respectively during surveyed period. AGP of the filtrated after autoclaved were higher than those of the filtrated only except some specific stations. The points of maximum growth were measured after addition of N, P and unenriched samples (control). The limiting factor was nitrogen only at site 5 in spring and phosphate appeared to be the major limiting nutrients in spike test throughout the year, especially during spring and autumn. Accoding to trophic level by Sudo(1980), the water quality of lake Jinyang were estimated mesotrophic at site 2, 4, 5, 6 in spring, at site 3, 6 in summer and at site 6 in autumn but all other sites were oligotrophic. But it is suggested that if we have not manigement of lake Jinyang, the water quality is possible to convert eutrophic.

In the study we measured and evaluated the acoustical property of a domestic spark gap type extracorporeal shock wave lithotripsy (ESWL). Altering the discharging medium between the electrodes of the shock wave generator (water, 1% an 10% NaCl electrolyte), we measured shock waveforms and sound pressure level (SPL). For the shock waves produced using the discharging medium, water, it was seen that the shock wave peak pressure went up to 70 MPa, and the SPL was in the range of 90 - 100 dB. As the concentration of NaCl increased in the electrolyte. the SPL did not change much and was shown to increase correlation with the discharging voltage. In the case of the discharging medium. 10% NaCl electrolyte, it was found that the shock amplitudes varied in a narrow range when being high in the concentration of NaCl and were large when being high in discharging voltages. While the stone fragmentation was in process, we measured the acoustic emission and compared their spectral properties.
