Purpose: The purpose of this study was to identify the association between Sasang constitution and type A/B personality. Method: The subjects for this study were 113 Korean adults living in Kangwon Province, the northeastern part of Korea. The data were collected from March 10 to April 13. 2002 using a structured questionnaire. The instrument for this study were QCSSII (Questionnaire for Sasang Constitution Clsssification II) by Kim et al.(1996), and the Revised Type A/B personality by Eysenck & Fulker(1983). The data were analyzed through the SPSS 10.0 for Windows program using frequency, percentage, $x^2$-test, ANOVA, and Pearson correlation coefficient. Results: The results of the study are as follows : 1. Of 113 Korean adults, the portion who were Taieum-in, Soeum-in, Soyang-in was 39.8%, 34.5%, 25.7% respectively. 2. For type A/B personality, mixed type was most common, 19.4% of the participants were of type B and 8.0%., type A. 3. For type A/B behavior, mixed type was most common at 47.8% and type A was 2.7%. 4. There were statistically significant differences in the Sasang constitutional type according to BMI (F=14.542, P<.001), and alcohol consumption (F=4.256, p<.018). 5. There were significant difference between type A/B Personality and BMI (F=3.592, P<.032). 6. The data shows correlations between BMI and amount smoked per day (r=2.74, P<.004), between BMI and alcohol consumption (r=-.303, p<.008), between BMI and Sasang constitutional type (r= -.592, p<.0001), between BMI and type A/B personality (r=285, p<.011), between amount smoked per day and alcohol consumption (r= .-361, p<.001). between alcohol consumption and Sasang constitutional type (r=-.306, p<.019). between perceived health state and type A/A personality (r= .246, p<.011). Conclusion: According to the above findings, it can be concluded that further research is need to understand the Sasang constitution for the discipline of Nursing and for nurses to prepare nursing protocols relevant to Sasang constitutional care. Also, Sasang constitution has to be considered in research and practice in the health care delivery system.

Objective: Low-dose aspirin have been proposed to improving endometrial receptivity and pregnancy rate in COH-IVF by increasing endometrial perfusion. However, the effect of low-dose aspirin in COH-IVF could be negligible because there have been large quantity of other important factors responsible for changing endometrial perfusion accompanied by COH procedure. In contrast, in frozen-thawed embryo transfer cycles which were not accompanied by COH procedure, the effects of low-dose aspirin in endometrial blood flow seems to be more certain than in COH-IVF cycles. In this study, we analyzed the effect of low-dose aspirin treatment on implantation and pregnancy rates in patients undergoing frozen-thawed embryo transfer Methods: From January 2003 to December 2003, total 264 cycles from 264 patients who attended infertility clinic at Samsung Cheil Hospital were enrolled in this study. All cases included in this study, embryos were frozen and thawed at the pronuclear stage and three days after incubation, at least 2 or more good quality embryos were transferred into uterus. In study group, low dose aspirin (100 mg/day) was administrated from the first or second date of menstrual day to 9 days after embryo transfer. On the other hand, control group did not take any medicine except estradiol valerate for endometrial priming. Several variables including implantation and pregnancy rates were compared in both groups. After then, each groups were stratified by endometrial thickness checked at embryo transfer (ET) day such as (28 mm versus <8 mm) and same variables above described were compared between study and control groups. Results: The mean age, infertility duration, endometrial thickness at embryo transfer day and mean number of transferred embryo were not significantly different in both groups. Also, implantation rates (study group: 15.8%, control group: 20.5%) and pregnancy rate (study group: 45.1%, control group: 43.5%) were not significantly different between two groups. (p>0.05) After we analyzed same variables stratified by endometrial thickness checked at embryo transfer day, we could not found any significant difference between study and control groups. Conclusions: Low-dose aspirin treatment seems to have no advantage of improving implantation and pregnancy rates in patients undergoing frozen-thawed embryo transfer.

Purpose: This study was designed to evaluate the effect of home care nursing intervention with parenteral hydration and IV anti-emetic therapy on distress, nutritional status, anxiety, depression and QOL in gynecologic cancer patients who were undergoing combination chemotherapy. Methods: Quasi-experimental design was used to test the intervention. Changes of result variables were measured to evaluate effects of the intervention. variables consisted of serum lab results(auto analytic equipment for lab), symptom distress Scale(McCorkle & Young, 1978; Song et al., 2000), nutritional status(body weight, circumference of upper arm, serum protein, serum albumin, oral intake per day), anxiety(Spielberger, 1972; Kim & Shin, 1978), depression(Zung, 1965; Kim, 1995) and QOL(Padilla et al., 1983; Lee & Jo, 1996). Subjects were selected among gynecologic cancer patients(EG 15 patients and CG 15 patients) by convenient sampling. Data collection was done from June to Nov. in 2000. Data were analyzed by Chi-test and Mann-whitney U test using SPSS Win 10.0. Result: Hypothesis 1, the EG receiving this intervention equals to lab test(Hb & ANC, GOT & GPT, BUN & Cr) the CG, was supported(u=69.50 p=.074; u=94.50, p= .455; u= 89.50, p= .339; u=106.50, p= .803; u=75.00, p= .119; u=97.50, p= .523). Hypothesis 2, the EG has less symptom distress than the CG, was also supported(u=43.50, p= .004). Hypothesis 3, the EG has higher nutritional status than the CG, was partially supported on daily oral intake (u=59.00, p= .025). Hypothesis 4, the EG has less anxiety than the CG, was rejected(u=86.50, p= .280). Hypothesis 5, the EG has less depression than the CG, was rejected(u=203.50, p= .228). and the last hypothesis 6, the EG has higher QOL than the CG was supported (u=51.50, p= .011). Conclusion: Home care nursing intervention undergone in this study was found to be effective to reduce patients' symptom distress and to improve their oral intake and QOL.

Color and its stability in venison, longissumus dorsi (LD) and quadriceps femoris (QF) muscles, from 8 wild Cervus nippon yesoensis (Japanese Yeso Deer) were investigated by means of the CIE L$^{*}a{*}b{*}$ measurement and autoxidation rate recorded using partially purified myoglobin. It was observed a common feature of the change of three mean values($L^{*}$, $a^{*}$ and $b^{*}$) in both LD and QF that mean value increased at 1 or 2 day post-mortem and then decreased during storage. The differences between 1 and 7 days was the largest in $a^{*}$ value than those in $L^{*}$ and $b^{*}$ values. The mean differences among storage days were only significant in $a^{*}$ except for $b^{*}$ of LD. It was same tendency that the mean difference of CIE $L^{*}$, $a^{*}$ and $b^{*}$ values during refrigerator storage was larger in $a^{*}$ than both in $L^{*}$ and $b^{*}$ reported in beef(Sekikawa et al., 1995) and venison(Stevenson et al., 1989) during storage. The smaller $a^{*}$ value was indicated that bright red of meat changed to dull red, brown red causing met-Mb formation. To compare of color stability with respects to the Mb autoxidation rate, we measured this rate of deer and horse muscles, because horse Mb was considered to have the fastest autoxidation rate among domestic animals, and we used crude Mb and pH 6.0, which might be reflected to the intact meat. Mean value of the autoxidation rate measured in this study in deer was 0.037 and that was 0.026 in horse(sigma). Although there was no significant mean difference and were different Mb purity between deer(A409/A 280 nm = 4.0) and horse(5.6), in generally Mb purity was the higher and the faster autoxidation rate, but this rate in deer was faster than in horse. These results might indicate that venison meat discolors at faster rate compared with beef.

The present study was carried out to evaluate whether the coculture system of human embryos with Vero cells can improve the quality of embryo or overcome the repetitive implantation failures in order to obtain pregnancy. From January to December 1996, a total 202 cases which patients with the problems of repetitive implantation failures (group I) or those with the poor embryonic quality in their previous cycles (group II) was analysed. The quality of cocultured embryo, pregnancy, on-going and implantation rates between coculture and control groups were compared. Of 93 cases in group I, coculture was performed in 34 cases and conventional IVF for the rest. Of 109 cases in group II, 36 for coculture and 73 for conventional IVF. In group I, pregnancy, on-going and implantation rates in coculture group (14/34 (41.2%), 9/34 (26.5%), 16/81 (19.8%), respectively) were higher than those of control (11/59 (18.6%), 8/59 (13.6%), 12/152 (7.9%), respectively). There is significance in the pregnancy and implantation rates (p=0.028 and p=0.015). In group II, pregnancy, on-going and implantation rates in coculture group (8/36 (22.2%), 5/36 (13.9%), 8/87 (9.2%), respectively) were higher than those of control (5/73 (6.8%), 3/73 (4.1%), 3/158 (1.9%), respectively). Like the result of group I, there is significance in the pregnancy and implantation rates (p=0.028 and p=0.022). Coculture system with Vero cells works well in the groups of the two indications. Although the case of 3 day-coculture was small as 15 cases in group II, 3 day-coculture improved pregnancy rate (4/15 (26.7%)). Therefore, 3 day-coculture with assisted hatching is recommended to the patients with poor embryonic quality. In conclusion, coculture system with Vero cells can be suggested as an effective method which improves pregnancy rate in those who have repetitive implantation failures or whose embryonic quality was poor in their previous cycles.

Observation of hydrometeors' behavior in the atmosphere is important to understand weather and climate. By conventional observations, we can get the distribution of water vapor at limited number of points on the earth. In this study, the precipitable water has been estimated from the split window channel data on GMS-5 based upon the technique developed by Chesters et al.(1983). To retrieve the precipitable water, water vapor absorption parameter depending on filter function of sensor has been derived using the regression analysis between the split window channel data and the radiosonde data observed at Osan, Pohang, Kwangiu and Cheju staions for 4 months. The air temperature of 700 hPa from the Global Spectral Model of Korea Meteorological Administration (GSM/KMA) has been used as mean air temperature for single layer radiation model. The retrieved precipitable water for the period from August 1996 through December 1996 are compared to radiosonde data. It is shown that the root mean square differences between radiosonde observations and the GMS-5 retrievals range from 0.65 g/$cm^2$ to 1.09 g/$cm^2$ with correlation coefficient of 0.46 on hourly basis. The monthly distribution of precipitable water from GMS-5 shows almost good representation in large scale. Precipitable water is produced 4 times a day at Korea Meteorological Administration in the form of grid point data with 0.5 degree lat./lon. resolution. The data can be used in the objective analysis for numerical weather prediction and to increase the accuracy of humidity analysis especially under clear sky condition. And also, the data is a useful complement to existing data set for climatological research. But it is necessary to get higher correlation between radiosonde observations and the GMS-5 retrievals for operational applications.

The effects of breed and sex on individual growth performance and feeding behaviour were studied between 45 and 90 kg BW in two replicates of forty group-housed pigs. The first and the second replicates were carried out during the warm season (i.e. between February and April 2003) and during the hot season (i.e. between August and October 2003), respectively. During the warm season, ambient temperature and relative humidity averaged $25.3^{\circ}C$ and 86.0%. The corresponding values for the hot season were $27.9^{\circ}C$ and 83.6%. The pigs were grouped in pens of 10 animals on the basis of breed (Creole or Large White) and sex (gilt or castrated male) and given ad libitum access to a grower diet (9.0 MJ/kg net energy and 158 g/kg crude protein) via feed intake recording equipment (Acema 48). An ear-tag transponder was inserted into each pig and this allowed the time, duration, and size of individual visits to be recorded. The growth performance and feeding pattern were significantly affected by breed, sex, and season. The Creole pigs (CR) had a lower average daily gain (ADG) (642 vs. 861 g/d, p<0.01) and carcass lean content ($LC_{90kg}$) (35.4 vs. 54.5%; p<0.01) and a higher backfat thickness at 90 kg BW ($BT_{90kg}$) (23.4 vs. 10.4 mm; p<0.01) than Large White pigs (LW) whereas the average daily feed intake (ADFI) was not affected by breed (2.34 vs. 2.22 kg/d, respectively for CR and LW pigs; p>0.10). Consequently, the food:gain ratio was higher in CR than in LW (3.65 vs. 2.58; p<0.01). CR had less frequent meals but ate more feed per meal than LW (5.9 vs. 8.8 meals/d and 431 vs. 279 g/meal; p<0.01). The rate of feed intake was lower (27.6 vs. 33.9 g/min; p<0.01) and the ingestion time per day and per meal were higher in CR than in LW (87.1 vs. 69.7 min/d and 15.8 vs. 8.4 min/meal; p<0.01). The ADFI and BT90 kg were higher (2.38 vs. 2.17 kg/d and 18.1 vs. 15.9 mm; p<0.05) and LC90 kg was lower (43.5 vs. 46.4%; p<0.01) in castrated males (CM) than in gilts (G) whereas ADG was not affected by sex (p = 0.12). The difference in lean content between CM and G was greater in CR than in LW. The ADFI and ADG were reduced during the hot season (2.18 vs.2.38 kg/d and 726 vs. 777 g/d, respectively; p<0.05) whereas feed conversion and carcass lean content were not affected by season (p>0.05). Average feeding time per meal and meal size decreased during the hot season (10.9 vs. 13.2 min/meal and 316 vs. 396 g/meal; p<0.01) whereas the rate of feed intake was not affected by season (p = 0.83). On average, 0.69 of total feed intake was consumed during the diurnal period. However, this partition of feed intake was significantly affected by breed, sex, and season. In conclusion, the breed, sex and season significantly affect performance and feeding pattern in growing pigs raised in a tropical climate. Moreover, the results obtained in the present study suggest that differences observed in BW composition between CR and LW are associated with difference in feeding behaviour, in particular, the short-term regulation of feed intake.

Objective: This study was performed to evaluate whether vitrification method could be used for the cryopreservation of human blastocysts derived from IVF program. Methods: Surplus embryos were obtained from consented IVF patients. Controlled ovarian hyperstimulation was done with midluteal GnRH agonist, gonadotropin and hCG. After oocyte retrieval and insemination, fresh embryo transfer was done at $4{\sim}8$ cell stage. The surplus embryos after ET were cultured in blastocyst medium up to 6 days after oocyte retrieval. Obtained blastocysts were cryopreserved with our vitrification method. Blastocysts were exposed to 1.5 Methylene glycol (EG) in phosphate buffered saline (PBS) for 2.5 minutes, followed by 5.5 M EG plus 1 M sucrose for 20 seconds. Then 1 to 3 blastocysts were mounted on electron microscope (EM) grid and the grid was plunged into liquid nitrogen for storage. For thawing, blastocyst-containing EM grids were sequentially transferred in 1.0 M, 0.5 M, 0.25 M, 0.125 M and 0 M sucrose solution at the intervals of2.5 minutes. And blastocysts were cultured for about 6 hours and only re-expanded blastocysts were transferred to uterus of the patients on 4 to 5 days after ovulation in natural cycle or on 18 to 19 day of artificial cycle. Results: From Oct. 1998 to Jul. 1999, 34 patients were agreed to participate in this study. The mean age and duration of infertility of the patients were 31.6 years and 4.1 years, respectively. Among 34 cycles. replacements could be done in 20 cycles (58.8%). A total 93 blastocysts were thawed and 48 (51.6%) of them survived. Thirty-eight blastocysts, mean 1.9 embryos per patient, were transferred, resulting in 5 clinical pregnancies which consisted of 1 triplet, 2 sets of twins and 2 singleton pregnancies. The pregnancy rate per transfer was 25% and implantation rate was 23.6%. Five patients delivered 7 healthy babies including 2 sets of twins at term. Conclusion: Successful pregnancies and deliveries were established after transfer of vitrified human blastocysts. Vitrification using ethylene glycol as cryoprotectant and electron microscope grid is a rapid and simple method that can be effectively applied for the cryopreservation of human blastocysts.

This study was performed to determine the level of soybean meal (SM) or feather meal (FM) that could substitute for fish meal in fat cod(Hexagrammos otakii Jordan et Starks) diet. A control diet with fish meal as protein source was included. The amount of 5, 10, 15 and 20% of SM or FM substituted for fish meal in the control diet, respectively. Amino acids supplementation in the 20% SM diet was compared. In addition, combination of 5% SM, 5% corn gluten meal, 5% meat meal, 5% blood meal and 5% FM was substituted for fish meal in the control diet. Duplicate groups of the 40 fish averaging 21g were fed one of 11 isoproteic (45%) and isolipidic (15%) experimental diets to satiation twice a day for 2 months. No significant differences were found among fish fed the control, substituting up to 20% SM or 10% FM in weight gain, feed efficiency, daily feed intake, and protein efficiency ratio (P>0.05). It is concluded that SM or FM can be used as a partial substitute for fish meal up to 20% or 10% in the control diet, respectively.

We investigated the effects of Acorus gramineus water extract on the blood lipid levels in high fat diet-fed obese male mice. We divided thirty-five C57BL/6 mice into 5 groups: normal group, control group, and groups treated with Acorus gramineus water extract at concentrations of 20, 100, and 500 ㎎/㎏. We inoculated Acorus gramineus water extract per orally once a day for 6 weeks respectively. The results revealed that Acorus gramineus water extracts had positive effects on the total cholesterol, triglyceride, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol levels.
