Pacific oysters Crassostrea gigas (Thunberg) were collected on April, 1999 and March­September, 2000 from Goseung Bay along the southern coast of Korea. The oysters tested cp;;ected from a depth of 0.5-2 m in which they cultured by a long line hanging method. The oxygen consumption rates (OCR) of oysters held under constant temperature and darkness (CC), were determined using an automatic intermittent-flow-respirometer (AIFR). Depending on holding periods after oyster collection, the experiments were divided into two groups: Group 7-d (held to ambient temperature for ca. 7 days) and Group 2l-d (held to ambient temperature for ca. 21 days). The OCR for Group 7-d single oyster displayed two peaks every day under CC, while Group 2l-d single oyster showed one peak every day. It is likely that the rhythmic patterns 02.6-12.8 hours) of the OCR in the Group 7-d single oyster may have been influenced by tidal currents at the sampling site. The rhythmic patterns (24.3-24.7 hours) in the Group 2l-d single oyster may have been shifted from two peaks to one peak each day under CC. The present study concludes that the OCR rhythm of wild oysters in nature is governed by two lunar-day clocks (24.8 hours); one driving one peak and the other driving the second peak. When oysters are subjected to the long-term CC conditions, one of the two-clock systems is depressed or only intermittently becomes active. Jpwever. the OCR rhythms by two to three oysters occurred arrhythmic patterns during the experiments and exhibited some evidence of weak rhythmicity of compared to those of a single oyster. It could be partly due to differences group effects.

To understand the factors influencing Atrial fibrillation and embolism in mitral valve surgery and prevent their risk, we have reviewed our 324 patients who underwent mitral valve surgery from Fev. 1982 to May 1992. Age, disease duration, lesion type, left ventricular function and left atrial dimension were chosen as preoperative factors influencing the incidence of atrial fibrillation and embolism and their postoperative course, The number and type of replaced valve, site of atriotmy, LA obliteration, ACT and use of Defibrillator were chaser. as operative factors influencing postoperative rhythm change and postop emb-olization. The results of analyses were as follows 1. The incidence of preoperative atrial fibrillation, systemic embolism and LA throbmus was 63. 6%, 10.56% and 19.8% relatively. 2. The preoperative factors of atrial fibrillation onset was old age, prolonged symptom duration, stenotic lesion, lager LAD and lower ejection fraction. In the preoperative systemic embolism preoperative factors were old age, female, stenotic lesion. The left atrial thrombus found more commonly in patients with atrial fibrillation, old age, prolonged symptom duration, stenotic lesion and low ejection fraction. 3. The preoperative atrial fibriation persisted postoperatively in 165[50.9%] and converted to normal sinus rhythm in 50[15.4%]. The preoperative normal sinus rhythm per-eisted in 100[31%] and atrial fibrillation was occured postoperatively in 9[2.7%]. The prolonged symptom duration was the preoperative factor of persist atrial fibrillation. 4. Among 95 long term follow-up patients, atiral fibrillation was continued in 59[60%]. Conversion to normal sinus rhythm was more common significantly in left atriotomy and bileaflet valve replacement. 5. There were 12 patients who had postoperative embolism. Female, persist atrial fibrillation, no LA olbiteration and tilting disc monocusp valve were considered as possible factors influencing postoperative embolism but was impossible to analyse their statistical significance due to small sample size. So we have concluded that the patients with above risk factors need anticoagulant and early surgical intervention. Left atriotomy with minimal atrial injury, left auricular obliteration and bileaflet valve replacement may be needed to reduce postoperative atrial fibrillation persist and embolism.

Six healthy female volunteers twice undertook an experiment with different types of clothing leaving the arms and legs covered or uncovered at $24{\pm}0.5^{\circ}C$ and $50{\pm}5%$ RH to study how different thermal stimulation to the distal extremities during the afternoon could modulate circadian parameters of body temperature rhythm. One type of clothing consisted of long-sleeved shirts and full-length trousers (Type I, 989 g, 0.991 clo); the other type consisted of half-sleeved shirts and knee-length trousers (Type II, 750 g, 0.747 clo). Subjects wore Type I or Type II clothing during the afternoon (14:00 h - 19:00 h), and Type I clothing during the evening (19:00 h - 22:30 h) and the night sleep (22:30 h - 06:00 h). Rectal temperature and skin temperatures at the arm and leg were measured continuously. Results were as follows: 1) The circadian amplitude of rectal temperature tended to be greater, and the acrophase was significantly earlier when wearing Type II rather than Type I clothing. 2) The circadian nadirs of skin temperatures of the arm and leg were significantly lower and the amplitudes were significantly greater with Type II clothing. In addition, the acrophase and bathyphase of the circadian rhythm of arm skin temperature were significantly earlier with Type II than Type I clothing. 3) The amplitude of rectal temperature was related closely with that of arm and leg skin temperature. These results suggest that a slightly cool thermal stress during the afternoon to the arms and legs exerted by wearing half-sleeved shirts and knee-length trousers induces a greater amplitude and a phase advance of the overt circadian rhythm of body temperature.

본 연구는 전문대학생의 우울 정도를 측정하고 대학생활 스트레스 요인들과 일주기성이 우울에 미치는 영향을 분석하였다. 광주지역에 소재한 전문대학교 학생 720명을 대상으로 2016년 10월 10일부터 10월 31일까지 설문조사를 실시하였으며 회수된 설문지 중 687부를 분석하였다. 연구결과 첫째, 학생들의 34.5%가 우울증 치료가 필요하며, 71.6%가 가벼운 우울증이 있는 것으로 나타났다. 둘째, 우울감은 여학생이 남학생보다 높았으며 부모와 별거시, 학년이 높을수록 높게 나타났다. 셋째, 일주기성과 우울과의 관계는 저녁활동형 일수록 우울감이 높았다. 넷째, 회귀분석 결과, 가치관으로 인한 스트레스, 일주기성, 학업스트레스, 취업스트레스 순으로 우울감에 미치는 영향이 크게 나타났다. 이러한 연구결과는 학생들의 우울증을 조기 발견하고 우울증 과 관련이 많은 스트레스 요인들을 감소시킬 수 있는 정신건강 프로그램이 필요함을 시사한다. 그러나 본 연구는 일부 지역 전문대학생에게 한정되어 있어 일반화시키기에는 무리가 있으며 향후 4년제 대학생과 전문대학생의 비교 연구가 필요하다.

One of the most widely recognized problems in patients with TGA [transposition of the great arteries] after the Senning operation is the occurrence of arrhythmias. From June 1982 through October 1984, 22 patients, 11 with "simple" and 11 with "complex" TGA, underwent correction of TGA by a modification of the Senning operation designed to avoid dysrhythmias. 16 were males and 6 females, with ages ranging from 3 months to 27 months. [mean age 10.8 months] 7 patients [31.8%], 1 with simple TCA and 6 with complex TGA, died in the early post-operative period. The operative mortality was 9.1% in "simple" TGA, and 54.9% in "complex" TGA. There were 4 late deaths but only one of these patients died of a dysrhythmia as a possible factor. The standard ECG [Electrocardiography] checked preoperatively showed sinus rhythm in 17 [77.3%], 1 AV block in 5 [22.7%]. In 22 patients studied postoperative 1st day, the incidence of arrhythmias was 63.6%, with significant incidence compared with preoperative study. [P<0.05]. But, in 15 patients studied postoperatively at intervals from 1 month to 26 months, the incidence of arrhythmias was 26.7%, with no significant incidence compared with preoperative study [P>0.1]. Our results indicate that a modified Senning operation may reduce the frequency of surgically induced arrhythmias. The mean frontal plane P-wave axis also revealed significant deviation to the right side [P<0.05], compared with preoperative study. These findings raise the possibility that what has been called sinus rhythm postoperatively may have a different origin and conduction sequence from normal. But the rhythm seems to be functionally similar.rhythm seems to be functionally similar.
