This study was performed to investigate the possible effect of garlic produced in Korea on the inhibition/reduction of growth of A. parasiticus, a toxigenic strain. The effect was studied using different concentrations of freeze-dried garlic in potato-dextrose agar (PDA) and/or in yeast-extract sucrose (YES) broth at $25^{\circ}C$ for 15 days. While inhibition of the fungal growth due to increasing the concentration of garlic was observed, the more remarkable effect was observed on the ninth day. Reduction of fungal diameter as a result of addition of garlic on PDA was observed to range between 3.4% to 20.1 % while reduction of mycelial weight in YES broth ranged from 9.9% to 30.5%. The 0.5% and 1.0% concentrations of garlic significantly reduced fungal diameter in PDA on the 9th day, while 0.1 %, 0.5%, and 1.0% concentrations of garlic significantly reduced the mycelial weight in YES broth (p<0.05). Dose-response relationships were observed between the concentration of garlic and inhibition of growth both in solid culture and in liquid culture. This study indicates that garlic could be an effective inhibitor at a human consumption level of the growth of A. parasiticus. More research is needed to study the inhibitory effects of the main active component of garlic.

The previous research for tourism education has focused on the development of curriculums and effective teaching techniques for the students who major in Tourism and the effective educational systems for professionals. But the tourism education for the people should be researched by another approach because tourism is regarded as a right. The purpose of this study is to define 'tourism education', to prove the necessity of the tourism education for the people, and to suggest a new tourism educational system. A lifelong(continuing) education is mentioned for this purpose, which includes tourism education in the elementary, secondary, higher, and adult education. At the elementary and secondary levels, an independent subject would be more effective dealing with when, where, how to enjoy tourism while some contents are now inserted in other subjects dealing with the hosts' mandatory such as how to greet foreign tourists. At the higher level, various cultural subjects of tourism would be open for all students and tourism education courses would be made for the teachers who could give tourism lectures in the elementary and secondary levels. In the adult education, more attention needs for the hosts of tourism destinations and the adults and elderly people.

Background: Fungal agents are commonly transmitted from dogs and cats to humans. Objective: To identify the mycoflora of and association of skin diseases in dogs and cats fed as pets indoors. Methods: A total of 435 animals (355 dogs and 80 cats) with or without skin lesions were included in the study; these animals lived indoors and had been examined in a veterinary hospital between August 2010 and May 2011. Their hair and scales were obtained using Mackenzie's brush technique,and a mycologic study was performed. Results: Of the 435 animals examined, 3.2% had dermatophytes (DM), including 1.5% of the dogs with dermatoses (D-dogs), 0.6% of the dogs with normal skin (N-dogs), 43.8% of the cats with dermatoses (D-cats), and 6.3% of the cats with normal skin (N-cats). All the DMs isolated were identified as Microsporum canis. Nondermatophyte molds were isolated from 24.1% of the animals examined, including 19.3% of the D-dogs, 29.7% of the N-dogs, 18.8% of the D-cats, and 26.6% of the N-cats. Of the 435 samples examined, 49.5% yielded Malassezia pachydermatis (Mz. pachydermatis),including those from 58.4% of the D-dogs, 53.8% of the N-dogs, 31.3% of the D-cats, and 17.2% of the N-cats. The prevalence of Mz. pachydermatis infection in dogs aged 6 years and more was higher than that in the other dogs. Conclusion: In this study, the prevalence of DM in dogs and cats was lower than that reported in previous studies. DMs were found in a significantly higher percentage of D-cats (43.8%) than D-dogs (1.5%) (p < .001) and of N-cats (6.3%) than N-dogs (0.6%) (p=0.022). The prevalence of nondermatophyte molds did not significantly differ between dogs and cats with dermatoses or normal skin.

본 연구의 목적은 정신질환자 가족의 스트레스 요인과 대처 방법을 파악하고, 사회적 지지의 완충효과를 확인하는데 있다. 1998년 3월 1일부터 3월 28일까지 서울ㆍ부곡ㆍ춘천 나주 등 4개 국립정신병원에 입원중인 정신질환자 가족과 외래를 방문한 가족 206명을 대상으로 설문지를 이용하여. 정신질환자 가족의 스트레스와 대처방법, 사회적 지지도에 관한 자료를 수집 분석하였다. 자료분석을 위한 통계적 유의수준은 α=0.05로 하였다. 정신질환자 가족의 스트레스 요인은 7개 요인으로 분류되었다. 정신질환자 가족들은 스트레스 대처방법으로 정서중심 대처방법보다 문제중심 대처방법을 더 많이 사용하였다. 사회적 지지는 정신질환자 가족이 경험하는 스트레스를 완충하여 주는 역할을 한다고 볼 수 없었다. 이는 이전의 정신질환자들이 겪는 스트레스 연구(불안)의 결과들과 일치하는 것이다. This is a confirmatory study to identify stressors, buffering effect of social supports and coping methods employed by family members of psychiatric patients who had utilized services at National Mental Hospitals(NMH). Data were collected from a convenient sample of 206 family members with a psychiatric patient under treatment at NMH in Seoul, Naju, Chuncheon and Bugok through a self-administrated survey, from March 1 to March 28, 1998. Stressors were measured by a 5-point Likert scale which had been proved to have both reliability and validity in previous studies. A measurement scale, developed by Jalowiec and adapted culture-specifically, was employed to measure the coping method to deal with stress by the family members. Social supports reflect number of persons (relatives or friends) whom the family member could talk to about the patients. A factor analysis identified 7 stressors and the respondents reported to have a substantial pressure derived from them. Most of the respondents had used problem-oriented methods to deal with stress. A buffering effect by social supports was not observed. Some implications were discussed in terms of clinical and public health education to reduce stress among the family members.

The purpose of this study was to determine the detailed customer satisfaction and dissatisfaction factors of family restaurants in Korea, and to then classify the factors into 3 groups, inlcuding core service, quality service, and basic service. ‘Core service’ represents the critical factors that generate both satisfaction and dissatisfaction; ‘quality service’ generates only satisfaction; and ‘basic service’ generates only dissatisfaction. This categorization is based on Herzberg’s motivation-hygiene theory (1976) as well as Cadotte & Turgeon (1988). Based on the characteristics of the three groups, differentiation strategies in managing customer service were suggested to the family restaurant managers. A qualitative research method, termed the critical incident technique (CIT), was used in the study. This method helps researchers find new factors or attributes by grouping key issues from the anecdotes (critical incidents) and then categorizing common factors from the key issues. This research categorized key satisfiers and dissatisfiers into 33 factors, which were from 402 critical incidents described by 261 respondents. Eleven factors (response to service failures, food taste and quality, attention paid to customers, coupon/mileage point/discount card, customer’s ordinary requests, waiting, food diversity, food price, facility sanitation, checking out, customer’s special requests) were classified into core service, which required maximum management not regarding the level of customer satisfaction. Six factors (employee attitude, event, education and explanation, complementary food, customer’s mistakes, attention paid to children) were classified into quality service, which required differentiation strategy management. Finally, nine factors (speed of food service, employee’s mistakes, food sanitation, atmosphere and interior, seating, forcing orders, parking, other customers, reservations) were classified into basic service, which required minimum management at the level of the industry standards.

Purpose: Potential benefits of eversion carotid endarterectomy (eCEA) compared with conventional carotid enderterectomy (cCEA) are more simple and faster reanastomosis with a low risk of restenosis. However, in Korea, eCEA is not popular having only one report of eCEA. This study aimed to investigate the results of eCEA. Methods: From July 2008 to September 2010, authors performed 36 eCEAs for patients with carotid artery stenosis in our hospital. Patients' demographics and clinical data were retrospectively reviewed. Regarding early (<30 days) results including the frequency of postoperative stroke, myocardial infarction, cerebral hyperperfusion syndrome, bleeding, cranial nerve palsy, new brain lesions (NBLs) on diffuse-weighted MRI (DW-MRI) and mortality were examined. Mid-term results such as stroke, death and restenosis after over thirty days were also examined. Results: Mean age was 66.6 years old and 88.9% of the patients were male. Twenty-four patients (66.7%) had a previous neurological event in the preceding 6 months. A carotid shunt was used in 3 cases (8.3%) and mean carotid clamping time was 25.4 minutes. One case (2.8%) of non-disabling ipsilateral stroke, 1 case (2.8%) of wound hematoma and 1 case (2.8%) of cranial nerve palsy developed after operation. DW-MRI was conducted in 27 patients (75.0%) and NBLs were detected in 4 patients (11.1%). One case (2.8%) of restenosis was discovered during the follow-up period (mean, 9.0 months), and there were no strokes or death. Conclusion: Early and mid-term postoperative stroke and complication rates of eCEA were acceptable in our series. However, to assess efficacy of eCEA, further large-volumed and long-term follow-up studies are needed.
