The purpose of this study was to investigate the attitude difference toward the school uniform, it was supposed that clothing acceptance was differentiated according to subjects. The subjects were grouped by 3 types which were students, teachers(school governors) and parents groups. The results were as follows; 1. Boy students reguired the more freedom of clothing than girls. 2. Teachers and parents groups considered that clothing affected student's behavior and self-esteem. 3. The acceptance of school plain dress was affected by atomosphere of home and school. 4. According to socioeconomic levels, there were differences in clothing acceptance and fashion acceptance.

This study was conducted to determine the stress response [ethological (operculum movement number (OMN)), hematological (hematocrit and hemoglobin), biochemical (glucose, cortisol and glutamic oxaloacetic transaminase (GOT))] in red spotted grouper, Epinephelus akaara during exposure of different water temperature in winter season. This species (Total length, 18.56±0.34 cm) previously maintained in water temperature of 15°C were transferred to 15, 20 and 25°C. During experimental period (7 days), OMN, hematocrit (Ht), glucose and GOT values were significantly high in 15°C when compared to 20 and 25°C. Hemoglobin value was also increased at 15°C, but no significant differences. There was no differences in cortisol levels among the temperature groups. No fish mortality was observed during the experimental period. From these results, 15°C is likely more stressful to red spotted grouper than 20°C and 25°C. These observations confirm that red spotted grouper adapts better to temperatures between 20 and 25°C during the winter season.

Skeletal deformities are significant problems that affect the growth and commercial value of fish reared in hatcheries. However, studies of bone metabolic process related to skeletal deformities are limited. We investigated the potential correlation between bone deformities and plasma calcium, phosphorus, and estradiol-17β levels in reared red spotted grouper (Epinephelus akaara) juveniles. We collected E. akaara frys from private farms at 110, 140, 180 and 300 days after hatching (DAH), and classified the normal and deformed fish by observing their external shape and inner frame by soft X-ray. We also analyzed the calcium, phosphorous, and estradiol-17β levels in their plasma. A comparison between normal and deformed fish, indicated that calcium and estradiol-17β levels were higher in deformed fish than in the normal at 180 and 300 DAH. The level of phosphorus was also higher in deformed individuals than in normal fish, but only at 300 DAH. These results suggest that skeletal deformities are associated with increases in plasma calcium, phosphorus, and estradiol-17β levels.

Purpose: This study set out to identify the association between the intraperitoneal CO2 concentrations and postoperative pain by dividing the participants into a control group and 2 experimental groups receiving irrigation (1 L and 2 L), and directly measuring their intraperitoneal CO2 concentrations with a CO2 gas detector. Methods: A total of 101 patients, American Society of Anesthesiologists physical status classification I and II patients aged 18–65 years were enrolled in the study. Group 1 did not receive irrigation with normal saline, while groups 2 and 3 were administered irrigation with 1 L and 2 L of normal saline, respectively, after laparoscopic cholecystectomy. Intraperitoneal CO2 concentrations were measured with a CO2 gas detector through the port, and postoperative pain was assessed on a visual analogue scale at 6, 12, and 24 hours after surgery. Results: The intraperitoneal CO2 concentrations were 1,016.0 ± 960.3 ppm in group 1, 524.5 ± 383.2 ppm in group 2, and 362.2 ± 293.6 ppm in group 3, showing significantly lower concentrations in groups 2 and 3. Postoperative pain was significantly lower in group 3 at 6 hours after surgery, and in groups 2 and 3 at 12 hours after the surgery. However, there was no significant difference between the 3 groups in postoperative pain 24 hours after the surgery. Conclusion: This study found a causal relationship between the amount of normal saline used for irrigation and the intraperitoneal CO2 concentrations in that irrigation with normal saline reduces pain on the day of the surgery.

We report the case of a 68-year-old man with a stromal tumor of uncertain malignant potential (STUMP), which had metastasized to the lung. The patient complained of an enlarged mass in the anterior chest. Chest computed tomography (CT) showed a sternal abscess with multiple nodules in both lungs. A thoracoscopic lung biopsy of the nodules and incision/drainage of the sternal mass were performed simultaneously. CT of the pelvis revealed an enlarged prostate with irregular cystic lesions in the pelvis. Prostate biopsy was done and demonstrated hypercellular stroma with minimal cytological atypia, a distinct pattern of STUMP. The sternal abscess proved to be tuberculosis and the lung lesion was consistent with STUMP, which had spread from the prostate. However, to our knowledge, the tuberculous abscess might not be assoicated with STUMP in the lung. The patient refused surgical prostatectomy and was discharged with anti-tuberculosis medication. On one-year follow up, the patient had no evidence of disease progression.

To evaluate the effects of benzo[a]pyrene (B[a]P), one of polycyclic aromatic hydrocarbons (PAHs), on in vitro oocyte maturation (GVBD) and sex steroid hormone production, maturing oocytes (oocyte diameters=0.74, 0.88 and 0.93 mm) of the longchin goby, Chasmichthys dolichognathus were incubated with B[a]P (1, 10 and 100 ng/mL) for 24 hours. After incubation, the oocytes were fixed with clearing solution (ethanol:formalin:glacial acrtic acid=6:3:1). The location of the germinal vesicle was observed under low-power magnification using a dissecting microscope. Steroids in aliquots of the incubation media were extracted twice using five volumes of ethylacetate:cyclohexane (1:1). Then, the T, E2 and 17α20βP levels were measured by RIA. In oocytes 0.74 mm diameter (vitellogenic oocytes), B[a]P had no significant effect on GVBD at the concentrations tested. In oocytes 0.88 mm diameter (fully vitellogenic oocytes), B[a]P inhibited GVBD significantly at 1 and 100 ng/mL. T production was decreased and the ratio of E2/T was increased significantly at 1 and 10 ng/mL compared with control. In 0.93 mm diameter oocytes (germinal vesicle located near the center of oocytes), B[a]P induced GVBD significantly at 10 and 100 ng/mL and decreased the ratio of E2/T significantly at 1 and 10 ng/mL compared with control. These findings suggest that B[a]P has different sensitivity to the oocyte maturation according to the oocyte diameters.

기업은 IT 를 일종의 자산으로 판단하여 IT 센터를 직접 구축하고 온프레미스 형태의 시스템을 운영했다. 그러나 경영 환경의 변화가 빨라지면서 IT 부문의 비용 효율성에 대한 압박도 커지고 있다. 클라우드 컴퓨팅을 도입하면 IT 자원을 효율적으로 활용하고 사용한 만큼 비용을 지불할 수 있어 IT 자원의 효율화가 가능하다. 하지만 무작정 클라우드로 옮기는 방식으로 인해 시스템 복잡성이 오히려 증가하고, 관리포인트 증가로 시스템 안전성을 해치는 상황이 벌어지고 있는 것도 현실이다. 신규 서비스 제공 시 기존 시스템 안전성을 해치지 않으면서 IT 자원의 효율적인 활용도 고려하는 방안으로 서비스 단위별 클라우드 컴퓨팅 도입을 검토하였다. 이 방법은 클라우드의 우수한 시스템을 사용하며, 실시간 오케스트레이션이 가능하고, 보안도 우수하다고 볼 수 있다. 기존 인프라를 유지하면서 클라우드 컴퓨팅을 구현한 하이브리드 방식으로 시스템 구축 결과 중단 없는 시스템 운영이 가능하였으며, 보안도 보다 강화된 결과를 얻었다. 향후 시스템 구축 시 온프레미스의 경우 서비스 단위로 클라우드 서버를 병행 운영한다면 운영효율성 뿐 아니라 기능성까지 만족시킬 수 있을 것으로 기대한다.
