This study explores communication competence and satisfaction in interpersonal relationship according to MBTI personality patterns. Looking at the distribution of MBTI personality patterns among male cadets, number of ESTJ(16.7%) is the highest, For female cadets, the highest in number is ENFJ(16.7%). There is discrepancy in communication competence depends on personality patterns, in order to verify such disparity, LSD was applied as a post-verification. As a result, there was discrepancy in communication competence between E(extravert) and I(introvert), also in satisfaction in interpersonal relationship between E(extravert) and I(introvert). Correlation between communication competence and satisfaction in interpersonal relationship showed static relation(r=.604(p<.01). In conclusion, this study proves significant relation of communication competence and satisfaction in interpersonal relationship according to cadet's personality patterns statistically. Also this study is significant because it can indicate directions that needs to be taken for discipline of cadets.

This study was designed to investigate the angiotensin convertin enzyme (ACE) inhibitory activity of skipjack/yellowpin tuna cooking broth. The cooking broth was pretreated with membrane filter (MW cut-off 5,000) to obtain the peptide fraction with ACE inhibition. the crude peptides fractionated with Amberlite IR-120 ($H^{+}$ form and followed by Bio-gel P-2, were separated into nine fractions (T-1 to T-9). The maximum inhibitory activity was observed in the fraction T-4 ($IC_{50}$ value, 0.619mg/ml). The abundant amino acids obtained from active fraction T-4 were phenylaanine, leucine and glutamic acid.

Y2K의 computer virus를 우려하면서 새로운 기대와 희망을 걸었떤 새 천년의 시작은 정말로 다사 다난했다고 보겠다. 미국의 대통령 선거체제의 현대화와 전체적인 개혁을 시사했다. 그러나 역사는 일상 생활의 반복으로 이루어진다는 사실을 모든 사람들이 절실하게 감지하도록 했다. ADA의 신임회장단은 대의원 총회의 수임사항으로 마련된 미국 치과의학의 장래에 대한 보고서를 여러 전문분야를 대표하는 특별위원회를 구성하여 빈틈없이 작성하고 있다. 또한 노령 인구의 폭발적인 증가에 대비하여 치과분야에서 정년 퇴직 후, 보람있는 여생을 보낼 수 있도록 미국 치과의사들이 정년퇴직을 위하여 빈틈없는 준비를 할 수 있도록 ADA는 치과인력의 수요와 충족을 비롯한 여러 가지 필요한 정보를 회원들에게 알리고 있다.

The present study was conducted to elucidate the functional property of tea extract obtained from tea extracts, semi-fermented tea(oolong tea) and fermented tea(black tea). Tea extracts exhibited remarkable nitrite-scavenging actions, and the action increased with the increased of the amount of tea extracts. The nitrite-scavenging actionof tea extracts showed pH dependent, highest at pH 1.2 and lowest at pH6.0. The nitrite-scavenging rate in tea extracts/amine/nitrite systems proved to be faster than that in amine/nitrite systems. To screen the nitrite-scavenging factors, tea extracts were fractionated into water-soluble, methanol-soluble, methanol-precipitate and crude catechin fraction. Among these fractions of tea extracts, the crude catechin fraction possessed greater nitrite-scavenging action than the other fractions. The nitrite-scavenging action of tea extracts increased with the contents of total phenols and an absorbance at 280nm, nitrite-scavenging factors were supposed to be and catechins in tea polyphenol compounds.

The purpose of this study is to evaluate for effective eye care service to the aged population of rural community. The results was as follow. 1. The aged who were using aids such as glasesses or had difficulties in everyday life without aids account for 66%. 2. The case of having some difficulties in everyday life and not using glasesses was 68persons(28.8%). 3. as for the reason why not using visual aids, 40.7% responded that they were able to see well without it and 31.4% could not have for burden of cost though in need of it.

Antioxidative effect of tea extracts from green tea(steamed, roasted), oolong tea and black tea was investigated. Antioxidative activities of the crude catechin fraction were the most effective in oolong tea which contained the highest level of (-)-epigallocatechin gallate(EGCg). The water-soluble fraction obtained from oolong tea exhibited binding with more ferrous than copper ions. It showed a synergistic effect when used with an antioxidant such as BHT(0.5mg) and $\alpha$-tocopherol(2mg). Especially, this synergistic effect was exhibited more with BHT than with $\alpha$-tocopherol. Also steamed green tea, roasted green tea and oolong tea showed remarkable free radical scavenging action. The SC50(the concentration of a water-soluble fraction which is required to scavenge 50% of 100$\mu$M 1, 1-diphenyl-2-picryl hydrazyl radicals) of steamed and roasted green tea, oolong tea and black tea extracts were 11.3$\mu\textrm{g}$/ml, 11.4$\mu\textrm{g}$/ml, 12.7 $\mu\textrm{g}$/ml and 14.9$\mu\textrm{g}$/ml, respectively. It is assumed that the antioxidative activity of tea extracts is due to inhibition of peroxidation free radical scavenging and binding action of ferrous ions by mainly tea polyphenol compounds.

Desmutagenicities against 2-amino-1-methyl-6-phenylimidazo[4, 5-b] pyridine(PhIP) and 2-amino-3, 8-dimethylimidazo[4, 5-f]quinoxaline(MelQx) of tea extracts (steamed green tea, roasted green tea, oolong tea and black tea) were investigated. All the fractions obtained from tea extracts showed strong desmutagenic activity against PhIP and MeIQx toward S. typhimurium TA 98 in the presence of the S-9 mix. The crude catechin fraction exhibited the strongest desmutagenic activity. Among these tea extracts, black tea especially exhibited the strongest desmutagenic activity and the activity was 70.9~91.0% against PhIP and 92.2~98.8% against MelQx at a concentration(0.5~1.0mg/plate) for drinking. The activity of authentic catechins of (-)-EGC, (-)-EGCg, (-)-ECg and (-)-EC were 79.5%, 60.2%, 46.1% and 43.5% against PhIP, and were 52.3%, 11.6%, 8.2% and 22.1% against MelQx by addition of 1.0mg/plate, respectively. The desmutagenic activity was supposedly due to the (-)-EGCg, (-)-EGC and (-)-EC in tea polyphenols, and the browning materials. The desmutagenicity was stronger when mutagens were preincubated with S-9 mix after reaciton with black tea extracts than when preincubated with them after reaction with S-9 mix. The desmutagenicity of tea extracts was rather expressed by reacting directly with mutagens than by deactivating the activated forms of mutagens.

Due to the aging population, the proportion of senior citizens is rapidly increasing. Naturally, managing the mental health of seniors has become crucial, and the need for programs to support a happy life for seniors is urgent. The proposed paper suggests ways to improve seniors' autobiographical reminiscence ability as a preventive measure for various mental illnesses, such as depression and dementia, and designs a mental digital healthcare program to support senior mental health counseling. The program is designed to gradually heal by focusing on counseling content that can recall past data.

The present study was designed to investigate effects of the addition of potato homogenates on fermentation control of salted anchovy. With the addition of $8\%$ (w/w) potato homogenates(P), amino-N content and pH were maintained at lower values in the muscle and juice of salted anchovy during all fermentation periods, And high values in external appearance of the salted and fermented anchovy-body during fermentation period were recorded. Consequently, the suppressing effect on the fermentation of salted anchovy of the addition of $8\%$ (w/w) potato homogenates was proved. As for the factors related to the suppressive effects on fermentation, there was no change in amino-N content, and viable cell counts and pH values were maintained.
