본 연구의 목적은 연령집단에 따른 허약의 예측요인을 분석하는 것이다. 연구의 목적을 위해 2014년 노인실태조사를 사용하여 총 4,123명을 분석의 대상으로 설정하였다. 허약을 예측하는데 있어 연령의 중요성을 고려하여, 본 연구는 대상자를 75세 이상 85세 미만의 중 고령노인집단(n=3,373명)과 85세 이상의 초 고령노인집단(n=750명)으로 분류하여 연구모형을 검증하였다. 중 고령노인집단에서 전 허약노인과 허약노인은 각각 1453명(약 43%), 1,268명(약 37%)으로 나타났으며, 초 고령노인 집단에서 전 허약과 허약노인은 304명(약 40%), 396명(약 52%)으로 나타났다. 회귀분석의 결과 건강단계에서 허약전 단계로 진입하는 예측요인은 중 고령노인집단에서는 여성, 낮은 교육수준, 많은 만성질환, 낙상 유경험자, 높은 우울, 낮은 인지기능이 허약 전 단계를 예측하는 유의한 변인으로 밝혀졌으며 초 고령노인집단은 여성, 높은 우울, 낮은 사회활동이 유의한 예측요인으로 밝혀졌다. 허약 전 단계에서 허약 단계로의 진입을 예측하는 요인으로는 중 고령노인집단은 여성, 높은 연령, 미취업, 많은 만성질환, 낙상 유경험자, 높은 우울, 낮은 인지기능이 유의한 변인이었으며, 초 고령노인 집단은 높은 연령, 많은 만성질환, 높은 우울, 낮은 인지기능이 유의한 예측요인으로 밝혀졌다. 본 연구는 연령의 세분화와 다각적인 요인의 접근으로 허약의 예측요인을 밝히고자 하였다. 연구를 통해 밝혀진 예측요인은 추후 허약에 대한 다각적 연구의 기초자료로서 활용되리라 기대한다. This study aims to investigate the predictors of frailty in different age groups. To address this purpose, this study used the 2014 Survey of the Living Conditions of the Elderly (SLCE). In the research model, 4,123 older adults aged 75 and older were included from the SLCE. All participants were subdivided into two age groups based on their age; the young old group (75-85) and the old-old group (85+). The young old group consisted of 1,453 (43%) pre-frail older adults and 1,268 (37%) frail older adults; the old-old group consisted of 304 (40%) pre-frail older adults and 396 (52%) frail older adults. Our regression analysis showed that in the young-old, being female, lower levels of education, having more chronic diseases, having fall experience, higher depression, lower cognitive functioning significantly predicted transition to pre-frailty from non-frail status. In the old-old, being female, higher depression, lower level of social activity were significant predictors. On the other hand, predictors of transition to frailty from pre-frail status in the young-old were being female, higher age, being unemployed, having more chronic diseases, having fall experience, higher depression, lower cognitive functioning. In the old-old, predictors of transition to frailty from pre-frail status were only higher age, having more chronic disease, higher depression, and lower cognitive functioning. The research findings can be used as a reference point in the making of strategies for preventing frailty.

Oxidation of Titanium Matrix Composites Reinforced with (TiB + TiC) Particulates

Young‑Jig Kim,Poonam Yadav,Junhee Hahn,Xiao Xiao,Dong Bok Lee 대한금속·재료학회 2019 METALS AND MATERIALS International Vol.25 No.3

Titanium matrix composites reinforced with (5, 10, 20) vol% (TiB + TiC) particulates were in situ synthesized using melting-investment casting method by reacting Ti with B4Cpowder. Their oxidation behavior was studied at 800–1000 °C inair. Formed scales consisted of transient TiO3and stable rutile-TiO2. More dispersed (TiB + TiC) particulates had higheroxidation resistance due to strong Ti–B and Ti–C bonding which required higher activation energy for oxidation comparedto Ti–Ti bonding in the matrix. However, such increment in oxidation resistance was limited by the formation of semiprotectivetitanium oxides, volatile B2O3,and CO2gas. With increment of (TiB + TiC), scales progressively became thinner,thus improving scale adherence.

항진균 세균의 특성 및 기능변화 가능성을 조사하기 위하여 버섯폐배지, 온천수, 해조류 및 삼림토양으로부터 식물병원성 진균에 대한 8 종의 항진균 활성 균주를 분리하였고 감마선(^60Co)을 이용하여 LD_95 에 돌연변이체를 유도하였다. Bactllus circulans K1, Burkholderia gladioli K4와 Bacillussubtilis YSl은 12 종의 식물병원성 진균에 대go 항진균 활성을 보였다. 이들 균주의 방사선감수성 조사결과 B. gladioliK4는 감마선에 대한 높은 감수성을 보였으며, D_10 값은 0.11kGy 였다. 감마선에 의해 유도된 Kl-1004와 YSl-1009는Botryosphaeria dothidea에 대해 항진균 활성이 증가되었다. B.subtilis YS1의 돌연변이체인 YSl-1006과 YS1-1009는 tebuconazol과 copper hydroxide에 대해 농약 저항성을 나타냈다. SAR535, SAR5108 과 SAR5l18 돌연변이체는 야생형 균주인 Streptomyces sp. SAR01에 비해 5 종의 식물병원성 진균에 대해 항진균 활성이 없었다. 연구결과, 방사선을 이용하여 다양한 기능의 돌연변이체 유도가 가능하였다. 이를 이용하여 항진균 활성 관련 유전자 연구 및 균주개량이 가능할 것으로 사료된다. In order to evaluate the antifungal activity of bacteria against plant pathogenic fungi, 8 bacteria were isolated from mushroom compost, hot spring, seaweed, and forest soil and mutants from them were induced by LD_(95) gamma radiadon(^(60)Co). Bacillus circuluns K1, Burkholderia gladioli K4 and Bacillus subtilis YS1 showed wide antifungal spectrum against 12 kinds of plant pathogenic fungi. From the radiation sensitivity test, R gladioli K4 was very sensitive to gamma radiation and its D_(10) value was 0.11 kGy. Antifungal activities of B. circulans K1-1004 and B. subtilis YS1-1009, which were induced by the radiation of ^(60)Co increased against Botryosphaeria dothidea. The mutant strains, B. subtilis YS1-1006 and B. subtilis YS1-1009 were resistant to tebuconazole and copper hydroxide. SAR535, SAR5108, and SAR5118 mutated from Streptomyces sp. SAR01 were antifungal activity deficient mutants against 5 kinds of plant pathogenic fungi compared to wild strain, so that they could be supposed to be model strains for studying antifungal mechanism. It is suggested that various functional types of mutants could be induced by gamma radiation and applied usefully.

The purpose of this study is to investigate the effects of the value system and material environment on consumers' brand orientation of clothes, and to understand how brand orientation, value system at home, and the motive for selecting a brand name are interrelated. As research method, questionnaire surveys were conducted on 498 high school and college girls in Seoul. Variables for home environment included status aspiration, materialism and traditionalism. Brand orientation was assessed based on brand involvement and brand loyalty. Variables for brand-selection motive included the place of a store, impulsive buying, and eight clothing attributes. Consumer groups were classified into four groups based on brand orientation, using brand involvement and brand loyalty median values: highly involved and loyal, highly involved and disloyal, less involved and loyal, and uninterested. The highly involved and loyal group showed a high level of status aspiration and traditionalism, belonged to a higher social class and had higher-educated parents. They took brand fame into much consideration when buying clothes. Additionally, this group paid much attention to the quality, fashion trends and comfort of the clothes, had a high level of expenditure on clothing and shopped for clothes mostly at department stores. The uninterested group showed a low level of status aspiration and traditionalism, belonged to the middle social class, and had lower-educated parents. Also, they took less consideration of clothing attributes, spent less money on clothing and did their clothes shopping at traditional markets and wholesale stores. The variables with the most amount of influence on brand involvement were in the order of social class, age, traditionalism and status aspiration (R²=.083). The variables with the most amount of influence on brand loyalty were found to be in the order of social class, age, traditionalism and materialism (R²=.090). Therefore, the most important variables for the clothing brand orientation of young females were social class, age and traditionalism at home.

The purpose of this study is to review and analyze the effects of sports massage treatments by kinds on the function of cardiac and lung system, on the maximum performance capacity during the stable period. In order to confirm the effects of sports massage on the function of cardiac and lung system. The objects of the test were 18 male students enrolled at W university, divided in 3 groups ; guoup A(effleurage), group B(petrissage), and group C(friction), each assigned with 6 students. The outcomes of this test are as follows. First, during the stable period, the function of cardiac and lung system was improved by the treatment of sports massage by kind. Among the groups, friction showed mere signficant(p< .05) improvement than effleurage and petrissage Second, the treatment of sports massage by kind enhanced the maximum performance capacity. The friction increased significantly(p<.05) in the maximum performance capacity of all groups. Form the outcomes summed up as above, it may be concluded that the treatment of sports massage is expected to bring warming up effect to increasing the function of cardiac and lung system as well as the maximum performance capacity during the stable period. As to the types of sports massage, friction may be most effective among other groups. It is, therefore, thought desirable to employ much more diverse and systematic approaches than before to detect thoroughly the effects of the sports massage treatment.

A self-microemulsifying drug delivery system (SMEDDS) was developed to increase the dissolution rate, solubility, and ultimately bioavailability of a poorly water soluble drug, lovastatin. SMEDDS was the mixtures of oils, surfactants, and cosurfactants, which emulsify under conditions of gentle agitation, similar to those which would be encountered in the gastro-intestinal (GI) tract. Various types of self-emulsifying formulations were prepared using four types of oil (Capryol 90, Lauroglycol 90, Labrafil M 1944 CS and Labrafil M 2125), two surfactants (Cremophor EL and Tween 80), and three cosurfactants (Carbitol, PEG 400 and propylene glycol). The efficiency of emulsification was studied using a laser diffraction size analyzer to determine particle size distributions of the resultant emulsions. Optimized formulations selected for bioavailability assessment were Carpryol 90 (40%), Cremophor EL (30%) and Carbitol (30%). SMEDDS containing lovastatin (20 mg and 5 mg) were compared to a conventional lovastatin tablet (Mevacor^? , 20 mg/tab) by the oral administration as prefilled hard gelatin capsules to fasted beagle dogs for in vivo study. The area under the serum concentration-time curve from time zero to the last measured time in serum, AUC_0→24h, was significantly greater in SMEDDS, suggesting that bioavailability increase 130% and 192% by the SMEDDS, respectively. The self-emulsifying formulations of lovastatin afforded the improvement in absolute oral bioavailability relative to previous data of lovastatin tablet formulation. These data indicate the utility of dispersed self-emulsifying formulations for the oral delivery of lovastatin and potentially other poorly absorbed drugs.

This study was conducted to investigate the differences in psychopathology and coping strategies among internet addictors, over users and non addictors in high school students. Subjects were 273 high school students in Seoul city. Self rating questionnaires included demographic data, Young’s Internet Addiction Scale, SCL-90-R, Beck Depression Inventory, Spielberger State-Trait Anxiety Inventory, and The Way of Coping Strategy. Subjects were classified into 3 groups (addiction, over use, non addiction) by Internet Addiction Scale score. Prevalence of internet addiction was 4.3% and male adolescents were more addictive than female. Students who were mainly involved with internet chatting or game showed higher internet addiction score. The addiction group and over use group showed higher level of somatization, obsession, interpersonal sensitivity, depression, anxiety, hostility, and paranoia than non-addicted group. Addiction group and over use group used passive coping strategies more frequently in the stressful situation than nonaddicted group. Also, the regression analysis for finding out causal factors that predicts internet addiction showed that emotion relieving strategy were important variable which predict internet addiction. Interpersonal sensitivity and emotion relieving coping strategy was important to predict addiction. This study showed that problematic internet use was closely associated with psychopathology and psychiatric comorbidity. And high interpersonal sensitivity and emotion relieving coping strategy were related with internet addiction in adolescence.
