The long-term mooring performed at a KOGA station, located at about $30^{\circ}20^{\prime}N$, $126^{\circ}12^{\prime}E$ in the East China Sea shelf, shows some different behaviors between "semi-diurnal" and "diurnal currents" defined as the currents with periods around, respectively, a half day and a day. They appear to be predominantly tidal having significant coherences with sea level changes around the semi-diurnal and diurnal frequencies. The "semi-diurnal current" is strongly barotropic all year round. However, contrastingly, it is largely baroclinic in summer in the area about 70 km nearer to the continental slope, referred to as the "slope-area", as was found in previous current observations. The "diurnal current" of tidal origin is strongly barotropic in winter. In spring and summer, however, it becomes more baroclinic although it still remains largely barotropic, also showing more of its barotropic nature than in the "slope-area". The inertial oscillation contributing to the "diurnal current" appears to be more prominent when the current is baroclinic, indicating the important role played by stratification in generation of inertial oscillations. Downward energy propagation of inertial oscillation is not observed, suggesting that it is not created at the surface by wind. Considering that the study area is both near a critical latitude and proximity to the continental slope, it is suggested that parametric subharmonic instability (PSI) plays a significant role in creating the baroclinic inertial oscillation.

The purpose of this study is to find out the temporal and spatial characteristics of the diurnal wind variation between coastal and inland areas using the hourly wind data of 58 AWS-stations in the South Korea which are collected during the 10 years from 1980. Diurnal variation is investigated by using the Fast Fourier Transform(FFT), and the wind direction in investigated by comparing C(sub)r with C(sub)v represented the constancy of wind. For the scalar wind speed, the maximum wind speed occurs in the daytime 14h to 16h. The maximum diurnal amplitude at coastal areas occurs from 12h to 16h, and is about 2 hours faster than that at inland areas. Vector mean wind speed is strong at coastal areas and Chupungnyong, Kumi, Taegu of inland areas. The diurnal variation ellipses make a right angle with coastline show that the land and sea breezes are prevailing. The constancy of wind is strong at all observations in January. In the relationship between $C_r and C_v, C_v is higher than C_r$.

This is an analysis of 32 patients who received long continuous corticosteroid drug due to some diseases. Patients were collected from June 1976 to March 1980. Blood cortisol level, variation of diurnal rhythm and side effects were studied. The Result as follows: 1. Side effects were observed in 24 patients(75%) and most common complaint was obesity. 2. Diurnal rhythm analysed by Doe's method shows abnormal diurnal rhythm is 21 out of 32(66%). 3. Mean durations or therapy of abnormal diurnal rhythm and normal diurnal rhythm were $55.7{\pm}4.4$ months and $43.9{\pm}7.0$ months respectively which shows statistically significant difference. 4. Mean cortisol value of steroid treated patients were lower than normal. 5. Reverse diurnal rhythm was 4 out of 21 patients. 6. 8 A.M. cortisol value is lower than 2 times of 8 P.M. in all patients who showed abnormal diurnal rhythm except one.

The hourly precipitation data from 1973 to 2007 observed at 60 weather stations over Korea are used to characterize the diurnal and semidiurnal cycles of total precipitation amount, intensity and frequency and examine their spatial patterns and interannual variations. The results show that the diurnal cycle peaks in the morning (03-09LST) and the semidiurnal cycle peaks in the late afternoon (16-20LST). It is found that the spatial variations of the peak phase of diurnal or semidiurnal cycle relative to their corresponding seasonal mean cycle are considerably small (large) for total precipitation amount and intensity (frequency, respectively) in both winter and summer seasons. Also, the diurnal phase variations for individual years relative to the seasonal mean precipitation show the significant interannual variability with dominant periods of 2-5 years for all three elements of precipitation and the slightly decreasing trend in total precipitation amount and intensity. To compare the relative contributions of frequency and intensity to the diurnal and semidiurnal cycles (and their sum) of total precipitation amount, the percentage variance of each cycle of precipitation amount explained by frequency is estimated. The fractional variance accounted for by precipitation intensity is greater than that of frequency for these three cycles. All above analyses suggest that intensity plays a more important role than frequency in the diurnal variations of total precipitation amount.

Purpose: Diabetic foot ulcers are closely related to body surface heat, which can be affected easily by temperature differences. This study examined the correlation between the healing process of diabetic wounds and abnormal diurnal temperature through an animal study. Materials and Methods: Rats in the abnormal diurnal temperature group and control group were given a 10 mm sized full-thickness skin ulcer. Wound size progression was observed in both groups. H&E and Masson's trichrome staining was performed at 14 days after wound formation, and the number of vessels per unit area and histology analysis were performed. The changes in the ulcer were measured through three dimensional cross-section area using INSIGHT^® devices. Results: The wound recovery period (granulation ingrowing) was 24 days in the abnormal diurnal temperature model and 20 days in the control group. The thickness of scar tissue was 402±23.19 ㎛ in the control group and 424.5±36.94 ㎛ in the diurnal temperature model. Neovascular formation was counted as 5.1±0.97 for the control group and 4.16±0.94 for the diurnal temperature model group. Conclusion: Delayed and inferior diabetic wound healing was observed in the abnormal diurnal temperature group, which was characterized by greater diurnal variations than the typical growth environment.

배 경 : 주간기분변동은 주요 우울장애, 멜랑콜리아 형의 세부진단으로 포함되어 있다. 그러나 현재까지의 연구를 종합해 보면 주간기분변동은 우울증의 고유한 증상인지 수면 양상의 변화와 관련된 현상인지, 혹은 별개의 다른 기전을 갖는 현상인지에 대해서 서로 모순되는 주장들이 혼재되어 있다. 이에 본 연구에서는 우울증의 세부 진단에 따른 주간 기분변동의 유무를 조사하고, 주간기분변동의 유무에 따른 수면 양상의 차이를 비교함으로써 주간기분변동과 수면 양상 사이의 관계를 찾아 보고자 하였다. 방 법 : 입원 혹은 의뢰된 우울장애 환자 62명을 대상으로 하여 주간기분변동은 Visual Analogue Mood Scale로, 수면 양상은 Pittsburgh Sleep Quality Index, 우울증의 심각도는 Hamilton Depression Rating Scale을 이용하여 측정하였다. 주간기분변동이 있는 군과 없는 군으로 나누고 HDRS 총점과 소항목, 그리고 PSQI 총점과 소항목을 변수로 하여 통계적 분석을 시행하였다. 결 과 : 주간기분변동의 빈도는 각각의 진단별로 차이가 없었으며, 주간기분변동이 있는 군과 없는 군으로 나누었을 때 중기 불면증과 수면 시간에 있어서 유의한 차이가 있었다(p<0.05). 또한 멜랑콜리아 형만을 대상으로 주간기분변동이 있는 군과 없는 군을 비교하였을 때 중기 불면증, 수면 시간뿐만 아니라 PSQI 총점, 수면 잠복기, 수면 장애, 주간의 기능 면에서 유의한 차이를 보였다(p<0.05). 결 론 : 주간기분변동은 멜랑콜리아 형의 우울장애 뿐만 아니라, 다른 우울장애에서도 존재하기 때문에 주간기분변동이 멜랑콜리아 형 우울장애의 특유한 증상으로 보기는 어려웠다. 주간기분변동이 있는 군에서 수면의 질이 더 좋은 것으로 나타났는데 이는 수면과 관련될 가능성이 높으며 향후 심도있는 연구가 필요할 것이다. 주간 기분변동은 외부 환경의 영향을 받기 쉬움으로 신뢰성을 높이기 위해서는 측정 기간과 횟수 등의 방법론적 연구도 필요할 것으로 생각된다.

Purpose: The purpose of this exploratory study was to find a specific time of day with a stable cortisol level and to investigate the relationship between salivary cortisol and sleep. Methods: A total of 36 Korean female college students participated in the study. Salivary specimens were collected 6 times a day for 2 days in different stressful situations. Sleep characteristics were measured using an actigraph while salivary specimens were collected. Perceived stress was evaluated using the Global Assessment of Recent Stress. Results: Depending on whether there were morning peak and/or afternoon elevations in the cortisol levels, the type of diurnal cortisol pattern was classified into 4 types. None of the cortisol levels in different times of the day showed significant relationships to perceived stress levels. Cortisol levels in the morning, levels of peak cortisol and diurnal differences of cortisol were significantly correlated with sleep duration. The time with most stable cortisol level was 9-10 pm. Conclusion: It is recommended that measurements of salivary cortisol are taken from 9-10 pm since it showed a stable value regardless of diurnal cortisol rhythm and sleep. Sleep duration should be considered as an important confounding factor in measuring cortisol levels in the morning and the diurnal differences of cortisol.

A simple but effective method has been developed for estimating diurnal and semi-diurnal tidal currents from trajectories of satellite-tracked drifters. The estimation method consists of separation of tidal current signals contained in the drifter trajectories, computation of undulations by diurnal and semi-diurnal currents, and correction of dominant diurnal and semi-diurnal tidal constituents. M$_2$ tidal currents estimated from drifter trajectories in the Yellow Sea are well consistent with those observed by moored current meters and this supports the validity of this method. We have constructed M$_2$ tidal current chart in the Yellow Sea by applying this method to available drifter trajectories collected during 1994-1998. According to this chart, M$_2$ current in the Yellow Sea rotates in the clockwise direction south of 35$^{\circ}$ 30'N but in the counterclockwise one to the north. Also it is found that the M$_2$ current is strong in the bank area northeast of the Changjiang River mouth and in the Korean coastal area, while it is weak in the deep central trough.
