Objectives : The aim of this study was to investigate the characteristics of Hwa-Byung(HB) patients, draw the clinical key issue of HB, and provide the data as the basis for development of Clinical Guideline of HB. Methods : The study participants included 151 subjects who thought they have HB in 9 site. For all patients, we used HB epidemiologic study protocol, which include the Korean version of the Structured Clinical Interview for the DSM-IV Diagnosis (SCID-1), diagnostic criteria of HB, symptoms check list, pattern identification tool, psychiastric psychological questionaires, and Framingham coronary risk score(FRS). Results : 1. For all participants, 62 % of subjects were diagnosed with HB. These patients had comorbid DSM-IV diagnoses with depression (65%) and anxiety (27%). But 22% of these patients had only HB. 2. HB patients had various physical symptoms when visiting, were diagnosed as various disease, and undergone medical treatments in the past. Among the diagonsed illness, Gastronitestinal diseases (51.6%), psychiatric disorders(40.9%), endocrine diseases(39.8%) were being the most frequent. The frequent physical symptoms of HB patients reported were chest discomfort, head ache, pallpitation, frequent sigh, amnesia, shoulder pain, dry mouth, eye fatigue etc. 3. HB patients had high scores in psychologic questionares, CES-D, STAI, and STAXI. It means that HB patients might be low-level emotional stability. 4. Participant had negative opinion about the treatment of HB that it would be difficult or impossible (65.7%), but they neglect the need of medical treatment. Conclusions : This result shows that HB is comorbid with various psychiatric disease, but it has different physio-psychological symptoms from others and there were only HB patients. so we identify HB is independent disease. Moreover, there were the wrong perception of HB which blocking treatments. These problems support that the neccesity of development of Clinical Guideline of HB.

In this study, the energy conversion equipment from the radiation energy to mechanical energy by using n­pentane as the operating fluid was constructed and the performance to pump the water was tested for the utilization of solar powered water pump. The equipment was designed optimally, after the theoretical analyses of the water pumping head and water quantity per cycle were done. The pentane vapour temperature in the condenser and the temperature of the outlet water from the condenser became lowered and the heat transfer rate became higher with decreasing the water inlet level to the condenser. The temperature difference between the condenser and the water tank was significant. Therefore, the distance between the water tank and condenser was recommended to be shorten and the diameter of their connecting pipe was recommended to be narrow in order to reduce the resistance of the fluid passage and improve the heat transfer rate. The amount of water pumped was 1.6­2.4 liters. Mass flow rate of the cooling water became lowered when the cooling water pipe was prolonged from the condenser to improve the heat transfer rate.

Major objectives were to evaluate effects of three schemes of bST-supplementation of Holstein cows (142.8 mg/14 d, POSILAC) during the prepartum and/or postpartum periods through 63 d (${\pm}3d$) of lactation. Measures evaluated the potential of treatments to improve body weight (BW) and body condition score (BCS), provoke changes in plasma concentrations of somatotropin (ST) and IGF-I, and improve milk yield, milk composition (percentages of protein and fat, and somatic cell counts), and several calving variables. Multiparous Holstein cows were randomly assigned to a $2{\times}2$ factorial arrangement of treatments (TRT) to give four groups (I = no bST, n = 26; II = bST postpartum, n = 25; III = bST prepartum, n = 27; IV = bST prepartum and postpartum, n = 25). During the prepartum period, cows in groups I and II were not supplemented but those in groups III and IV were supplemented every 2-wk beginning 21 d before expected calving date through calving. During the first 63 DIM only cows in groups II and IV were supplemented with bST. From 64 DIM through the end of lactation cows in all groups were supplemented with the full lactation dose of bST (500 mg/14 d). The BW and BCS were recorded weekly throughout the prepartum and postpartum periods and every 2-wk beyond 70 DIM. Blood samples were collected 3-times a week for analyses of ST and IGF-I. Milk yields were recorded daily though 150 DIM. Prepartum supplementation of bST did not affect BW or BCS, but mean concentrations of ST were increased 12.2% and were 15.5% greater at calving. Overall, mean concentration of IGF-I was not affected by treatment but concentrations were greater at 1 and 2 wk before calving in bST-supplemented cows. During the first 63 DIM the BW and BCS were not affected by treatment. Significant effects of bST-supplementation were detected on concentrations of ST, IGF-I and on milk yield compared to non-supplemented cows in group I. Postpartum concentrations of ST were greater in bST-supplemented cows (TRT II and IV; +41.9 and 54.6%). However, concentrations of IGF-I were greater only in cows in group IV (+25.9%) during the postpartum period. Overall, the three bST-supplemented groups had greater actual milk yield than the control group (I) during the first 63 and 150 DIM. The actual milk yields during 63 and 150 DIM were 6.5 and 4.6 kg/d greater for cows in group IV than cows in group I and the 305-d ME milk yield also was 15.6% greater. No adverse effects of TRT were observed on calf birth weight, colostrum immunoglobulins, ease of calving or other measures evaluated.

This study was carried out to identify the effects of seaweed extracts(GA14) on growth of two rice cultivars, Junambyo and Donganbyo. Seedling qualities of two cultivars were better in all items including heading dates at early stage treated at seedling plus 2-3 leaf stages than at single treatment of seedling. Ripening ratio of Junambyo in paddy field was increased 0.3% by seaweed extracts(GA14) treatment, but that of Donganbyo decreased 0.5%. 1,000 grain weight of Junambyo and Donanbyo by seaweed extracts(GA14) treatment was two to four grams higher and the yield of two cultivars was also higher by three to four percent. Appearance characters of two rice cultivars was high in head, while damaged, chalky and crack rate were low at seaweed extracts(GA14) treatment. Protein, moisture and amylose characteristics related to table quality of Junambyo were not different by seaweed extracts treatment, but table values was high in only treatment. Donganbyo was also similar to Junambyo, but table quality was slightly high at non-treatment.

Organic matter is very important and essential factor to maintain productivity of paddy field. But as meat consumption and the demand of grain increase, the demand of forage also increased gradually in Korea. So the amount of organic matter in paddy field have been declined gradually by the reduction of return of rice straw for the forage use for cattle. There is not enough alternative resources for forage, we guess this trend of organic matter decline in paddy field would continue for the time being in Korea. So this study was performed to confirm the variation of organic matter and change of rice yield to select suitable rice cultivars which yield reduction is small in condition of organic matter decrease in paddy field. To confirm the change of rice growth and yield in condition of organic matter decrease in paddy field, we transplanted 10 rice cultivars which yield reduction are small in low fertilizer condition. We transplanted it Buan where double cropping of winter barley continues several years on June 10. Planting density were $70plants/3.3m^2$ Fertilizer amount was $N-P_2O_5-K_2O=9-4.5-5.7kg/10a$ and fertilizer split application of nitrogen was basal-tillering stage-panicle initiation = 50-20-30%. And in the other cultivation management, we observed rice standard culture of NICS. In paddy field where withdraw straws of barley and rice, the organic matter content showed tendency to decrease as the years go on. During rice cultivation season, organic matter decreased little by little, but it increased again after rice harvest season. Rice yield was more in order of Sodami, Chunghaejinmi and Saenuri. We judge that there is an advantage in rice yield of rice cultivars which have later heading date because of suitable ripening temperature. Although Sobibyeo and Shindongjinbyeo showed high yield, head rice yield decreased severely owing to chalky and cracked rice.

The spermiogenesis of a Korean octopus, Octopus minor, inhabiting western of Korea Sea was observed by electron microscopy . The obtained results are as follows: The spermiogenesis of Octopus miner proceeds through four stages; early- , mid- , and late-spermatid, and mature sperm. An early spermatid is a spherical cell looking light due to the low electron density. The acrosome formed from Golgi complex of the upper nucleus looks dark due to the high electron density. The extra-nuclear rod (enr) stemming from proximal centriole is transformed from round shape into oval shape, elongating to the upper nucleus. In our observation, the axoneme was being formed from distal centriole, and the manchette composed of a number of microtubules is also found around nuclear membrane. In a mid-spermatid, chromatins in the nucleus contract shaping fine threads, and the manchette is also observed around nuclear membrane. Especially, the spherical acrosome is transformed into long oval one which is tinged with a number of horizontal stripes and has the middle electron density. In a late-spermatid, chromatins in the nucleus contract thick and short. Furthermore, the mitochondrial sleeve, in which the axoneme is surrounded with mitochondria, is observed at middle piece. The axoneme has a typical structure of 9+2 and around it, 9 coarse fibers are observed. Also in the acrosome cavity of mature sperm, horizontal striation is found. However, regularly spaced processes are peculiarly observed in there. A sperm is about 390 fm long, whose head is bent a little like a banana while the acrosome region is helical. In the middle piece of sperm, $11\sim12$ mitochondria are surrounding coarse fibers that reach the main piece of tail, while nothing but 9+2 structured axoneme is found in the end piece.

Purpose: Basal cell carcinoma is one of the most common cancers in the western population and the annual incidence rate is still on an increasing course. In Asian countries such as Korea, the incidence of basal cell carcinoma is reported to be remarkably low but is estimated to be in a steep increase nowadays. This study was to analyze the recent clinical trends of basal cell carcinoma in Korea by reviewing a single institution's experience. Methods: Throughout an 11-year period, the surgical excision of 143 cases of basal cell carcinoma was performed in our department. General data of these cases such as the primary site of cancer, age and sex of the patient, operative methods, recurrence rate were reviewed retrospectively. Results: Among the 143 patients included in this study, 82 patients were men and 61 patients were women. The ages ranged from 27 to 89 years with a mean age of 64.0 years. The head and neck region was the most frequently involved primary site for the cancer as 95.1% of the total cases occurred in this area. Especially the nose and perinasal area were the most frequent region, which was followed by the periorbital area, cheek, and perioral area. During this study period, 9 cases showed recurrence of the cancer as the overall recurrence rate was 6.3%. Conclusion: Gradual increase in the incidence of basal cell carcinoma was demonstrated in this study. Basal cell carcinoma showed high incidence in the old-age population as 68.5% of the total patients were more than 60 years of age. High recurrence rate was noted in the nasal region especially after local flap reconstruction. A more cautious approach is to be required when handing such high risk lesions. Multiple factors such as extended life span, increased outdoor leisure activity and exposure to sunlight, higher accessibility to medical services and increased understanding of the public about skin cancer are assumed to be the main reasons for this increase of basal cell carcinoma.

Purpose: The committee on trauma of the american college of surgeons, in its manual resources for optimal care of the injured patients involved in falls from less than 20 feet need not be taken to trauma centers. Because triage criteria dictate less urgency for low-level falls, this classification scheme has demerits for early detection and treatment of serious problems in the emergency room. Methods: A prospective analysis was conducted of 182 patients treated for fall-related trauma from June 2003 to March 2004. Falls were classified as group A (<3 m), group B (${\geq}3m$, <6 m), and group C (${\geq}6m$). Collected data included the patient's age, gender, site and height of fall, surface fallen upon, body area of first impact, body regions of injuries, Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), and Injury Severity Score (ISS). Results: The 182 patients were classified as group A (105) 57.7%, group B (61) 33.5%, and group C (16) 8.8%. There was a weak positive correlation between the height of fall and the patients' ISS in the three groups (p<0.001). There were significant differences in GCS (p=0.017), RTS (p=0.034), and ISS (p=0.007) between group A and B. In cases that the head was the initial impact area of the body, the GCS (p<0.001) and the RTS (p=0.002) were lower, but the ISS (p<0.001) was higher than it was for other type of injuries. Hard surfaces as an impact surface type, had an influence on the GCS (p<0.001) and the ISS (p=0.025). Conclusion: To simply categorize patients who fall over 6 meters as severely injured patients doesn't have much meaning, and though patients may have fallen less than 6 meters, they should be categorized by using the dynamics (impact surface type, initial body - impact area) of their fall.

A 3-year-old, 43kg, pregnant Great Pyrenese was examined for clinical signs of acute weakness and anorexia for 4 days. The dog was in lateral recumbency at referral. The rectal temperature was within reference range, and the respiratory and heart rates were 36 breaths/min and 58 beats/min, respectively. The abdomen was distended, and several puppies were palpated. The mean fetal head diameter was 2.8cm in the ultrasonographic examination. The initial complete blood count and serum biochemical examinations revealed mild dehydration, mud hyperglycemia, hypochloremia, hyperkalemia, hyponatremia, and low sodium-potassium ratio. Serum BUN and total cholesterol values were slightly high. Hypoadrenocortical crisis was suspected on the basis of signs of acute collapse, hyponatremia and hyperkalemia. Adrenal gland function was evaluated by an ACTH stimulation test. The baseline cortisol concentration was $18.6{\mu}g/dl$ and the concentration at 1 hour after administration of tetracosactrin (ACTH, Synacthen) was $8{\mu}g/dl$. The dog was treated for the correction of assumed hypoadrenocortical crisis and substantial hyperkalemia. In addition to rapid infusion with saline solution, other medications administered intravenously included sodium bicarbonate and cimetidine hydrochloride. The dog was monitored with repeated serum electrolyte examination. After clinical stabilization, cesarean section was performed. All of 13 puppies were delivered, and the dog recovered from anesthesia without complications. The values of postpartum blood tests returned to normal or within reference range. The dog remained healthily.

Surface charge characteristics of Ultisol(Luisiana soil from Philippines), Alfisol(Maahas soil from Philippines), and Inceptisol(Yongii soil from Korea) were studied by way of potentiometric titration, backtitration technique, and ion adsorption method(or CEC - AEC method). The PZNC(point of zero net charge) values determined by ion adsorption method were much lower than the natural pHs in all soils, indicating that all soil samples bore net negative surface charge. The PZSE (point of zero salt effect) values determined by potentiometric titration and backtitration technique were identical in Luisiana and Yongii soils but not in Maaghas soil. All soils showed higher PZSE values than PZNC values probably due to the influence of permanent negative charge. The permanent charge calculated by the theory of Uehara and Gillman (1980) occupied quite low portion of the CEC measured at pH 7 in all soils. Backtitration technique corrected errors of potentiometric titration at extreme pH. However, it still overestimate the surface charge compared with ion adsorption method. Therefore, the ion adsorption method was recommanded for the surface charge measurement of the usual soils which have high negative charge components.
