  • We identified the benthos collected from intertidal zone in Sacho, Naedong, Oran and Kusong of Haenam peninsula in October, 1990 and May, 1991 and examined the distribution pattern on the bases of the analysis of community structure and the physicochemical analysis of sediment including the grain component. The identified benthos consisted of 141 species and 4,641 individuals. The number of species and individuals of Mollusca, Arthropoda and Annelida occupy more than $85\%$ of the total number. When the intertidal zone were divided into soft area and rocky area the species found in rocky area(114 species) were present in a more diverse way than that in soft area(69 species). The composition of species found in 4 localities turned out to be very similar in soft area while in rocky area the most diverse species were found in Kusong. The seasonal appearance frequency of species and individuals showed that the number collected in the spring(106 species, 3,002 individuals) was higher than that in the fall(85 species, 1,639 individuals). The most dominant species was Cerithideopsilla djadjariensis belonging to Gastropoda, Mollusca(412 individuals) and the species collected more than 200 individuals were 5 species of Mollusca and 1 species of Arthropoda. The species diversity index of 4 localities was in the order of Kusong, Oran, Naedong and Sacho revealed no significant differences among regions. The dominance index was low in Kusong and was high in Sacho. The index of interstational species similarity in soft sediment was very similar with $0.44{\sim}0.53$ value and the index was quite high in Kusong and Oran. This agrees very well with the similarity of the grain component of sediment. In case of rocky area the index was quite low with 0.27 for Kusong and Sacho situated far away from each other. Thus the present study suggests that the distribution of the species was subjected to the physicochemical environmental factor such as the grain component of sediment and the content of organic materials including the geographical factor.

  • Objective: To evaluate whether diagnostic laparoscopy before transcervical fallopian tube catheterization (TFTC) would improve tubal recanalization rate and pregnancy rate in patients with bilateral proximal tubal blockage in hysterosalpingogram (HSG). Methods: The retrospective study was performed in those underwent TFTC from January 1998 to December 2001. A total of 50 patients with bilateral proximal tubal blockage in HSG were subjected to TFTC sequentially using repeated HSG (rHSG), selective salpingography (SS) followed by tubal catheterization (TFTC). Each procedure was terminated once patency had been achieved without proceding to the next technique. In Group A patients (n=35, 64 tubes), diagnostic laparoscopy was performed before TFTC was taken to exclude the tube combined with peritubal adhesion or distal tubal pathology. In Group B, patients (n=15, 26 tubes) were performed TFTC without diagnostic laparoscopy. Results: There were significant difference in clinical pregnancy rate (45.7% vs 15.4%, p=0.034) but no differences were found in recanalization rate (75.0% vs 73.1%) and complication rate (8.6% vs 13.3%). Although there is no signficant difference, more tubes were canalized by SS, which means tubal obstruction rather than occlusion, in Group A (25.0% vs 5.3%, p=0.069). Conclusion: Diagnostic laparoscopy would be effective in the selection of tube for the relatively inexpensive and less invasive TFTC or patients in need of assisted reproductive technologies. With the tubes without combined peritubal adhesion or distal tubal pathology, pregnancy rate was significantly increased.

The level of nursing needs of overall nursing care(3.93) and the levels of satisfaction(3.86) was relatively high. The nursing needs by category of nursing care, the highest need was in the emotional and psychological care(4.09), and the lowest need was in physical need(3.73). The satisfactions by category of nursing care, the highest satisfaction was in emotional and psychological care(4.11) and the lowest satisfaction was in education in self care(3.64). The significant differences between nursing needs and satisfactions were found on education in infant care(p=.005), and education in self care(p=.020). 3. Among items of physical care, 'accurate medication and treatment(4.21)', 'control of postpartum hemorrhage(4.13)', 'pain control and care of episiotomy wound (4.12)' and 'regular observation of postpartum conditions(4.09)' showed high nursing needs. 'Accurate medication and treatment(4.31)', 'regular observation of postpartum condition(4.24)', 'control of postpartum hemorrhage(4.22)' and 'pain control and care of episiotomy wound(4.12)' showed high satisfaction levels. 4. Among items of emotional and psychological care, 'personal treatment(4.32)', kind and faithful care(4.30)', 'detailed explanation on the treatment or nursing care(4.25)', 'adequate draping during the care and treatment(4.23)' and detailed explanation on a doubt(4.13)', showed high nursing needs, 'personal treatment(4.52)', 'kind and faithful care(4.45)', 'detailed explanation on a doubt(4.24)', 'detailed explanation on the treatment or nursing care(4.21)' and 'adequate draping during the care and treatment(4.18)' showed high satisfaction of nursing care. Difference between the level of nursing needs and satisfaction was significant except item of 'early contacts with their baby and breast feeding'. 5. Among items of environmental care, the highest level of need and satisfaction were on the items of 'neat bedding and clothes(4.05, 4.21)' and 'room cleansing or care of room(4.01, 4.28)'. Differences between the level of nursing care and satisfaction were 'room cleansing of care of room'. 6. Among items of educational needs on self care, 'sitz bath method(4.22)', 'high risk symptoms to immediate clinic visits(4.13)', 'the timing of tub bath(4.05)' and 'good secretion of breast milk(4.03)', showed high nursing needs, 'sitz bath method(4.22)' showed high satisfaction of nursing care. Differences between the level of nursing care and satisfaction were 'the timing of hair shampoo', 'the timing of tub bath', ' the method of pad change', 'postpartum exercise', 'good secretion of breast milk', 'maintenance of breast figure', 'contraindicated drugs in postpartum women', 'kegel exercise' and 'breast self examination'. 7. Among items of educational needs on infant care, 'immunization of infants(4.36)', 'symptoms of sickness to immediate clinic visits(4.28)'. 'safety and emergency care(4.28)', 'umbilical care(4.26)', 'feeding times and intervals(4.24)', 'normal growth and development of infant(4.24)' and 'infection control(4.22)', showed high level of nursing care, 'immunization of infants(4.21)', 'feeding times and intervals(4.17)', were high satisfaction items showed significant differences between the level of nursing care and satisfaction. 8. Relationship between nursing needs and levels of satisfaction among postpartum women were as follows : 1) Physical area : There were no significant differences in the level of nursing needs, but satisfaction levels were significantly different among 'working mothers', 'baby's weights', 'baby's sex', 'planning of feeding' and 'routes of receiving postpartum informations'. 2) Emotional and psychological area : The level of nursing needs were significantly different in the area of 'confidence in self care'. Satisfaction levels were significantly different among 'baby's sex', 'baby's weights', 'the confidence of infant care' and 'working mother'. 3) Environment area : There were on significant differences in the level of nursing needs, but satisfaction levels were significantly different among 'maternal age' and 'baby's weights'. 4) Education in self care : The level of nursing needs were significantly different among 'parity history' and 'type of family formation'. Satisfaction levels were significantly different among 'working mother', 'baby's sex', 'antenatal care', 'postpartum education', 'planning of feeding', 'routes of receiving postpartum informations'. 5) Education in infant care area : The level of nursing needs were significantly different among 'parity history'. Satisfaction levels were significantly different among 'baby's sex', 'receiving postpartum education or not' and 'working mother'.

  • The purpose of this study was to examine the effect of exercise and diet control program on blood pattern in obese children. The subjects of this study were five obese boys aged from 8 to 12 participating in the control period(C) for 3 days, exercise period(E) for one week, and exercise+energy restriction period(EER) for another one week, consecutively. The intensity of the exercise was 60~70% of HRmax and the energy was restricted at 493kcal/day. Daily mean total energy intake was 2,152${\pm}$138kcal. 1,861${\pm}$138kca1, and 1,368${\pm}$87kcal for the period C, E and EER, respectively. Body weight of after the program was significantly decreased from 48.94$\pm$5.11kg to 45.94${\pm}$4.74kg(P<0.01). And skinfold thickness. %fat. lean body mass, body mass index were significantly decreased(p<0.01). Blood sugar concentration was not significantly affected by weight loss, but alkaline phosphatase activity was significantly decreased. Concentrations of total lipid, LDL-cholesterol, triglyceride, phospholipid were not significantly decreased. But concentrations of HDL-cholesterol, %HDL-cholesterol, free fatty acid were significantly increased and concentration of VLDL-cholesterol, atherogenic index were significantly decreased. The results of this study showed that the obese children had a tendency to decrease coronary heart disease risk in the respect of plasma HDL-cholesterol and VLDL-cholesterol concentration by the exercise plus energy restriction program. Thus if we apply the lower intensity or duration of exercise for them this program might be more effective on the obese children.

  • Purpose: To analyze the outcome of radiation therapy for patients with a metastatic carcinoma of cervical lymph nodes from an unknown primary (MUO), and identify the prognostic factors for these patients. Materials and Methods: Between July 1981 and June 1999, 39 patients with MUO underwent radiation therapy with curative intent. Twelve patients were treated with radiation therapy alone (Group 1), 8 with neoadjuvant chemotherapy followed by radiation therapy (Group 2), and 19 with either an excision or neck dissection and postoperative radiation therapy (Group 3). There were 31 males and 8 females, with a median age of 55 years, ranging from 25 to 77 ears. The median duration of follow-up was 38 months, ranging from 3 to 249 months. Results: The 5-year overall survival rate was $55\%$. According to the treatment modality, the 5-year disease-free survival rates of Groups 1, 2 and 3 were 48, 19 and $75\%$, respectively (p=0.0324). In addition to the treatment modality, the appearance of the primary site was a significant prognostic factor for disease-free survival (p=0.0085). Conclusion: Surgical resection and radiation therapy achieves a superior disease-free survival compared to radiation therapy alone, either with or without chemotherapy Further investigation Is needed to evaluate the role of chemotherapy in the treatment of MUO.

  • From July 1983 to June 1995, 95 consecutive patients with mitral stenosis were treated surgically in the Department of Thoracic and Cardiovascular Surgery, Chonbuk national University Hospital, mitral valve replacement(MVR) in 62 patients and open mitral commissurotomy(OMC) in 33 patients. Mitral stenosis combined with coronary artery disease, with aortic valve disease, or wish mitral valvular Insufficiency, were excluded from this study. Surgical procedures for mitral stenosis were evaluated, according to complication, reoperation, mor- tality, nd functional change at mid- and long-term postoperative period. Cardiothoracic ratio in the MVR group was greater than the OMC group(0.59 $\pm$0.07 in MVR, 0.53 $\pm$0. 07 in OMC, p<0.05), but other variables(age, sex, MYHA functional classification, EKG finding, echocardiographic finding) did not show significant difference between two groups in the preoperative periods. Even though pathologic valvular lesion(Sellor's pathologic type m: 35 in MVR, 13 in OMC) and valvular calcification(35 in MVR, 11 in OMC) were severe in the MVR group(p=0.001) at intraoperative observation, OMC was possible in 11 patients(23.9%) among 46 patients with valvular calcification and in 13 patients(27.1 %) among 61 patients with Sellor's pathologic type IH . There was no significant difference in early and late mortality, actuarial survival(75% in MVR, 87.6% in OMC at 12 year), but early and late hemorrhagic, thromboembolic complications in the MVR group were greater than in the OMC. Functional changes in NYHA functional classification, EKG lEnding, cardiothoraclc ratio, and echocardiographic finding(EF, LVIDS, LWDd, LAD) did not differ between two groups in mid- and long-term postoperative periods. We conclude that our efforts for preservation of the native valve would be continued, because hemorrhagic and thromboembolic complications in the MVR were greater than in the OMC, and OMC was possible even in patients with severely stenotic and calcified mitral valve, although there was no sis-nificant difference in the functional change, mortality, and survival between the M VR and OMC.

  • As a part of investigation for utilizing anchovy more effectively as a food source, this work was undertaken the changes in keeping quality and taste compounds in the extracts from rapid fermented anchovy sauce during storage at room temperature. Rapid fermented products was made of chopped anchovy, water, koji and soybean protein isolate (20:10:2:1, w/w) thorough hydroxazine for 6 hours at $50^{\circ}C$. The liquified anchovy sauce extracts, contained 15% salt(w/w), were stored for 60 days at room temperature. The changes in pH, acidity, amino nitrogen and contents of taste compounds of the products were negligible during storage. The viable cell counts and histamines of the products were less than 30(colony/e extracts), 7.2-21.8(mg/100g extracts) during storage predominant free amino acids showed in the extracts from products were alanine, glutamic acid, histidine, lysine, leucine, valine and the total contents of those free amino acids were 60.4-64.3% of total free amino acids at final stage of storage. The major nucleotides and their related compounds of the products were revealed hypoxanthine, which were 69% over the total nucleotides and their related compounds. Using the omission test, the major taste compounds in the products were revealed free amino acids, nucleotides and their related compounds. The non-volatile organic acids, total creatinine, betaine, and TMAO were seemed to act an auxiliary role in taste of the extracts from rapid fermented anchovy sauce.

  • The purpose of this study was to determine the effect of a pulsed Nd:YAG laser irradiation on human gingival tissues. The patients, who were planned to be treated by clinical crown lengthening procedure and gingivectomy, were selected. All the patients received oral hygiene instruction, scaling and root planing at preoperation. The crest of gingival tissue on upper and lower anterior teeth was irradiated by a pulsed Nd:YAG laser(El. EN. EN060, Italy) with a fiber optic of 300 m in contact mode for 20 seconds. Gingival tissues were divided into 4 groups according to the laser power of 1.0W(10Hz, 100mJ), 2.0W(20Hz, 100mJ), 3.0W(30Hz, 100mJ) and 4.0W(40Hz, 100mJ). Immediately after the laser irradiation, the specimens were excised, fixed 10% neutral formalin, sectioned $4-6{\mu}m$ thick, stained by Hematoxylin-Eosin and Periodic Acid Schiff stain and observed under light microscope. The removed tissue depth and the coagulated layer depth due to a laser irradiation by a laser irradiation were measured on the microphotographs. The difference of measurements according to the different laser power was statistical1y analyzed by Kruskal Wallis Test with SAS program. The results were as follows : 1. In histologic findings of irradiated gingival tissues; a. In the irradiated gingival specimen with 1.0W laser power, some vesicles were observed in limited superficial layer of gingival epithelium. b. In the irradiated gingival specimen with 2.0W and 3.0W laser power, the epithelium was almost removed except for the traces of viable basal cell remnants at ret peg, and coagulation necrosis related with the thermal effect of laser was noted. c. In the irradiated gingival specimen with 4.0W laser power, complete removal of epithelium, partial removal of underlying connective tissue, and the coagulation necrosis of subjacent gingival tissue were shown. 2. The removed tissue depth was deeper in the irradiated specimens with higher power. There was a statistical significance in the difference of removed tissue depth between 1.0W group ($44.54{\pm}6.99um$) and 3.0W group ($99.75{\pm}6.64{\mu}m$), and between 1.0W group($44.54{\pm}6.99{\mu}m$) and 4.0W group($111.36{\pm}4.50{\mu}m$), and between 2.0W group($98.01{\pm}4.53{\mu}m$) and 4.0W group($111.36{\pm}4.50{\mu}m$)(P<0.05). 3. The coagulated layer depth was deeper in the irradiated specimens with higher power. There was a statistical significance in the difference of coagulated layer depth between 1.0W group($31.82{\pm}8.99{\mu}m$) and 3.0W group($55.99{\pm}20.94{\mu}m$), and between 1.0W group($31.82{\pm}8.99{\mu}m$) and 4.0W group($83.68{\pm}10.34{\mu}m$)(P<0.05). From this study, the results demonstrated that the effects of a pulsed Nd:YAG laser irradiation on gingival tissues seemed to depend on the laser power and that the irradiation with high power could be harmful to adjacent healthy tissue.

  • For the effective use of salmon processing by-products, the food components of muscle around pectoral fin (MAPF) were investigated and compared with those of salmon fillet muscle (SFM). The proximate composition of MAPF was 64.4% for the moisture, 17.2% for the crude protein, 16.2% for the crude lipid and 1.4% for the ash. The pH, volatile basic nitrogen (VBN) content and yield of MAPF were 6.73, 7.8 mg/100 g and 7.4 (g/100 g SFM), respectively. The trichloroacetic acid (TCA) soluble-N content of MAPF was 479 mg/100 g, which was lower than that (612 mg/100 g) of SFM. The Hunter value of MAPF was 54.86 for L value, 22.08 for a value, 22.41 for b value and 52.35 for ${\Delta}$E value, which were similar to those of SFM. The total content in amino acids of MAPF was 17.1 g/100 g, its major amino acids were aspartic acid, glutamic acid, leucine and lysine. The major fatty acids of MAPF were 16:0, 18:1n-9 and 18:2n-6, 20:5n-3 and 22:6n-3. No differences were found in the major fatty acids and the major amino acids between MAPF and SFM. The calcium and phosphorus contents of MAPF were 19.1 mg/100 g and 211.7 g/100 g, respectively. These results suggested that MAPF could be used as seafood resources.

  • This study investigated the biological activities and effects of Korean Zingiber mioga R. (flower buds and rhizome) on memory. The general composition, minerals, anti-oxidative activities, and AChE inhibitory effects were analyzed, and NORT (Novel object recognition test) and Y-Maze test in vivo were performed. The general contents (moisture, crude fat, crude protein, and crude ash; wet basis) of ZB (flower buds) were 91.96%, 0.15%, 1.99%, and 11.90%, respectively. The general contents (moisture, crude fat, crude protein, and crude ash; wet basis) of ZR (rhizome) were 75.21%, 0.53%, 2.20%, and 9.50%, respectively. The macro mineral contents (Ca, P, Na, and K) of ZB were 31.70 mg%, 15.20 mg%, 8.20 mg%, and 258.60 mg%, respectively. Inhibitory effects (IC50 value) of DPPH and ABTS radicals were higher with ZBD (flower buds water extract) than with ZBE (flower buds EtOH extract), ZRD (rhizome water extract) or ZRE (rhizome EtOH extract). AChE inhibitory effect of ZBD was higher and that of ZRD. NORT and Y-Maze test were performed with scopolamine-induced mice treated with ZBD and ZBE. In NORT, effects of ZBD and ZBE were similar to that of donepezil. In the Y-maze test, performances of ZBD and ZBE-treated mice were similar to that of the normal group. These results suggest that Korean Zingiber mioga R. has potential to be developed into a new functional food for cognition enhancement in the global food market.
