A study was conducted to evaluate isolation rate and distribution of mating type of M.gypseum complex Arthroderma(A.) gypsea and A.incurvata. Seventeen(17) strains were isolated from children patients and sixty(60) strains were from elementary school playgrounds, flower beds, and childrens playgrounds in Taegu area. The strains were crossed with test strains of A.gypsea and A. incurvata which were provided by Tokyo university. The results were summarized as follows; Of seventeen(17) strains, thirteen(13) were isolated from male children and ten(10) were A.incurvata and three(3) A.gypsea, and four(4) were from female children and all iou, strains were A.incurvata. Face(Tinea facial) was more frequently affected to compare with other clinical type. Of seventeen(17) strains isolated from patients, six(6) were A.incurvata "+" type and eight (8) were "-" type, and two(2) were A.gypsea "+" type and one(1) was "-" type. Of sixty (60) strains isolated from soil, sixteen (16) were A.gypsea "+" type and fifteen(15) were"-" type. and fifteen(15) were A. incurvata "+" type and fourteen(14) were "-" type.) were A. incurvata "+" type and fourteen(14) were "-" type. &"-&" type.t; type.

This study investigated the effects of spousal intervention in housework on female depression. To achieve this, an empirical 10-day field survey of 119 mothers of children after school age was conducted in Suwon, Incheon, Yeoju and Gwangju, Gyeonggi-do through structured questionnaires. The findings were as follows. Spousal intervention in housework had a significant effect on female depression, but there were different prevalence rates of female depression according to the status of spousal childcare on weekdays and weekends. In other words, there was a difference in the effects of spousal intervention in housework on female depression according to weekday childcare and weekend childcare. These findings indicate that reducing housework burdens by spousal intervention in housework helps to lower and prevent female depression. Consequently, because there is a difference in the effects of spousal intervention in housework on female depression according to the level of simple weekday or weekend childcare and the degree of intervention, spousal intervention and sharing all family management duties, including housework and childcare, can maximize the effect.

This study was carried out to isolate the colonies of dominant fermented bacteria from Kimchi (Korean native fermented foodstuffs) and investigate their inhibitory potentials on mutagenesis and carcinogenesis induced by N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) as direct carcinogen. For this purpose, single cell gel electrophoresis technique (SCGE assay, or comet assay) which is a sensitive and rapid technique for detecting the presence of DNA strand breaks in individual cells was used. DNA damages of Kimchi isolates were compared with that of the positive control, MNNG. Among 3 isolates from Tongbaechu Kimchi, two isolates B-1 and B-2 showed antigenotoxicities (p<0.01). All 4 isolates from Yulmu Kimchi had antigenotoxicities (p<0.05). Also, 3 of 5 isolates from Chonggak Kimchi and 2 of 9 isolates from Kaktugi were antigenotoxic (p<0.05 and p<0.01, respectively).

This study was designed to compare various dietary assessment methods and to determine the appropriate method that would be reliable for monitoring the adherence to a fat-modified diet. Dietary intake data was collected from the twenty-two (12 males, 10 females), type IIa hypercholesterolemic patients by the 24-hour dietary recall and the food records of various durations(9, 7, 4, 3days). Intakes of energy, protein, fat, carbohydrates, cholesterol, polyunsaturated fatty acids, saturated fatty acids, monounsaturated fatty acids, P/S ratio, and alcohol were analyzed by a computer-assisted method using the Natinal Heart, Lungand Blood Institute Nutrition Data System. The nutrient intake data of the 24-hour recall method were consistently higher than tat of the food record method. In all subjects, food record keeping of the 7 consecutive days provided acceptable dietary data (within 5% difference) when compared to that of the 9 consecutive days. Food records of 4 consecutive days however, were found to be adequate for female subjects, showing a sex difference. Except for P/S ratio, nutrient intakes did not vary significantly between weekdays and weekend-days. Among other components, alcohol and P/S ratio were shown to be the two most varied components in this study.

This study aimed to investigate the effects of motive of use, stress and interpersonal satisfaction on smartphone overdependence in dental hygiene undergraduates. A questionnaire survey was conducted on 216 dental hygiene students in colleges in Dajeon and Chungnam regions. The results showed that motive of use(3-4hours/>4hours)(${\beta}=-0.178$), weekday usage (<3hours/3-4hours)(${\beta}=0.163$), and weekday usage (${\beta}=0.196$) had a high impact on smartphone overdependence in dental hygiene students. Weekday usage dummy 1 was the factor with the greatest impact, with an explanatory power of 25.6%. Additional studies on various factors that affect smartphone overdependence as well as education programs for preventing smartphone overdependence in dental hygiene students are needed.

가뭄이 매년 지속됨에 따라 고랭지배추 재배지에서도 관수의 필요성이 인식되면서 관수를 실시하고 있으며, 대부분 스프링클러로 관수하고, 분수호스나 점적호스도 일부 이용하고 있으나 아직 토양수분, 토성이나 작물상태, 재배시기 등 환경요인을 고려한 과학적인 수분관리가 이루어지지 못하고 있어 고품질 안정생산을 위해서는 수분관리의 과학화가 필요한 실정이다. 물을 최소화 하면서 관비가 가능한 점적 호스 재배는 적정한 비료를 필요한 위치에 공급하는 방식으로 비료의 효율을 높이면서 환경오염을 최소화하고, 비료과다 시용에 따른 환경오염 등을 회피할 수 있는 좋은 수단이다. 본 연구는 앞으로 고랭지배추 점적호스 재배시 가뭄 극복과 효율적인 시비를 위한 적정 관비횟수를 구명하고자 하였다. 배추품종은 수호를 이용하였으며 관비횟수는 2회(20일 간격), 3회(15일), 4회(10일), 6회(7일), 관행(추비3회) 등 5처리를 두었으며 기준시비량은 N-P-K=32.0-7.8-19.8kg/10a로 하였으며 관비농도는 EC 1.2 dS/m fh 하였다. 시험은 고령지농업연구소 시험포장에서 6월 하순부터 8월 상순까지 무멀칭 노지재배를 하였다. 관비는 정식후 7일째부터 주었으며 관비량은 1회 구당 20ℓ를 주었다. 시험구배치는 단구제 3반복으로 배치하였다. 생육시기별로 초장, 엽장, 엽폭 모두 관비횟수가 많은 처리에서 생육이 좋았으며 6회 처리가 가장 생육이 좋았다. 주당 외엽수와 내엽수는 관행보다는 관비횟수가 많을수록 많아져 관비 6회에서 주당 69.7매로 가장 많았으며 주중과 구중도 관행에 비해 관수횟수가 많아질수록 높아졌으며 관비 6회에서 주중은 2,439g, 구중은 1,917g 으로 높게 나타나, 고랭지배추 관비횟수는 EC 1.2 dS/m 농도에서 6회를 한 것이 생육이 양호하였다.

The malo-alcoholic fermentation characteristics of Schiozaccharomyces japonicus var. japonicus which was freshly isolated from strawberry were studied. A good assimilation of malic acid by the strain was observed under the following conditions：pH 4.2∼4.8, alcohol content less than 12％, sulfur dioxide concentration less, than 150 ppm, and less than 0.01％ of Mn$\^$2＋/ as MnSO$_4$. The strain could remove 0.3％ of malic acid completely in 6 days under stationary culture at 30$^{\circ}C$. Shaking the culture could promote growth of the strain but did not affect on the malo-alcoholic fermentation.
