This study aims to promote the necessity for future research from the perspective of the indoor environment by analyzing the trend of domestic COVID-19 confirmed cases and examining previous quantitative research cases. The limitations of the qualitative management plan were identified by analyzing the trend of confirmed cases and deaths in Korea and the trend before and after the implementation of 'social distancing' and 'step-by-step daily recovery', which are actually being applied. The trend of initial and follow-up measures for the outbreak of infectious diseases in Korea is judged to be a case where the importance of qualitative and quantitative management should be confirmed to prepare absolute quarantine measures. The results suggest that examining previous research cases and preparing through advanced research for effective application.

This study was conducted to investigate the effect of Nelumbo nucifera G. (NN) powder on cookie quality characteristics. The cookies were made with various NN powder levels (1, 3, and 5%). Crude fiber, crude ash, and the Mg contents of cookies with added NN powder were higher in concentration than those of the control group. Salinity of NN-powder added groups was not significantly different when it was compared with the control group's salinity. No significant difference among the groups were observed for specific volume, but the width determined by water content in the dough decreased as the amount of added NN powder increased. The L-value of the cookies was significantly larger than that of the control group. The a- and b-values were the highest for the 5% substituted NN flour. According to the sensory evaluation of the cookies, scores for color, flavor, and texture increased with increasing amounts of added NN powder. The overall acceptance of the 3% NN added cookies was greater than that of the 1 and 5% cookies.

This study was conducted to investigate the effects of saltwort, on the quality characteristics of sponge cake. In addition, we examined the commercialization potential of sponge cake containing saltwort. To accomplish this, saltwort was added to sponge cakes at concentrations of 0%, 3%, 5% and 7% and quality and sensory tests were then conducted. The 7% group had the highest water and ash content. There was no difference in the fat content between samples. The control group showed the highest protein content and the lowest specific gravity. As the content of saltwort increased, the specific gravity of the sponge cake increased. Additionally, the dough yield and loss during baking were highest, in the control group, and these values decreased as the saltwort content increased. Similarly, the volume and specific volume were highest in the control group, and these values decreased as the content of saltwort powder increased. Color measurements of the samples, revealed that the L-value decreased as the content of saltwort powder increased. Furthermore, the a-value of the saltwort powder groups was higher than that of the control group and the b-value was highest in the 7% group. There were no differences in elasticity and cohesion between samples, but chewiness and brittleness increased the content of saltwort powder increased. The results of the sensory test revealed that the color, flavor and taste scores were the highest in the 5% group. The pore size was greatest in the control group, while hardness was greatest in the 7% group, chewiness was highest in the 5% group and moistness was highest in the 5% group. Finally, the overall preference was for the 5% group.

The aim of this study was to better understand the factors of the mentoring function in the foodservice industry that improve the organizational commitment of subordinates, and to asses the roles that trust towards supervisors play in the relationship between the mentoring and organizational commitment. A survey was of subordinates who were conducting the mentoring in foodservice companies (hotels, family restaurants) located in Seoul and Gyeonggi area was conducted from May 1 to May 30, 2008. The questionnaires were distributed to 400 employees in 50 restaurants and, 341 of them were received and a total of 320 were finally analyzed. The results were as follows. First, the effect of mentoring functions on the organizational commitment of subordinates indicated that the career developing function and psychosocial function had a significant positive effect on the emotional commitment and normative commitment (p<.01), and the career developing function, psychosocial function and role modeling function had a significant positive effect on the enduring commitment (p<.01). Second, the mediating roles of supervisory trust in the relationship between mentoring functions and organizational commitment of subordinates indicated that supervisory trust mediated the relationship between the career developing function of the mentoring functions, and enduring commitment and normative commitment in addition, it met the mediating requirements in terms of the relationship between the role modeling function, and the emotional commitment, enduring commitment and normative commitment. Consequently, the high career developing function, psychosocial function and role modeling function in mentoring raised the level of organizational commitment;thus, the mentoring system should used as on of the mentoring functions in the foodservice industry and mentoring functions should be also established.

In order to cope with risk issues of overseas on 4,4'-diaminodiphenylmethane (4,4'-MDA) known to used in the production of polyamide resins, we investigated on 4,4'-MDA migration from plastic cooking utensils. 93 samples of plastic cooking utensils were collected from the retail markets in 7 major cities of Korea during March to June, 2007 and 4,4'-MDA levels migrated to food simulants, water, 4% acetic acid, 20% ethanol and n-heptane, on plastic cooking utensils was quantified by liquid chromatography with tandem mass spectrometry (LC-MS/MS). 4,4'- MDA was detected in 14 samples, and the levels of 4,4'-MDA migrated to food simulants were in the range of 0.001 ~ 0.026 ppm. Among them, the 4,4'-MDA migration amounts of 2 samples were above 0.01 ppm defined by the EU.

부산시민의 외식실태를 조사하기 위하여 부산직할시에 거주하거나 직장을 가진 국민학교 4학년 이상의 남녀 464명을 대상으로 외식성향(때, 동기, 자주 가는 음식점의 종류, 비용, 선호도 등)을 설문지를 통하여 조사한 결과 다음과 같은 결과를 얻었다. 외식은 점심 때보다 저녁에 더 많이 하며, 외식을 하는 동기는 가족끼리 외출을 하였을 때가 가장 많고 다음으로 모임이 있을 때와 친구를 만났을 때 순이었다. 점심 때 자주 가는 음식점으는 분식집이 가장 많고 다음으로 중국집과 한식집 순이였으며, 저녁 때는 한식집이 가장 많고 다음으로 갈비집과 중국집 순으로 점심 때와는 차이가 있었다. 외식비로 지출하는 1인당 비용은 점심 때는 전체의 71.88%의 사람들이 4, 000원 이하의 음식을 먹는데 비해 저녁에는 54%이상이 5천윈 이상을 지출하여 점심 때보다 저녁 때의 외식비가 많은 것을 볼 수 있다. 한번 갔던 음식점에 다시 가는 이유로는 음식맛이 좋기 때문이 가장 많았으며 다음으로 위생적이기 때문과 음식가격이 싸기 때문 순이였으며, 다시 가지 않는 이유로는 역시 음식 맛이 없기 때문이 가장 높고 다음으로 비위생적과 가격이 비싸기 때문인 것으로 나타났다. 이상과 같은 결과는 연령과 성별 뿐만 아니라 직업에 따라 차이가 있는 것을 볼 수 있었다.

This study investigated the quality characteristics between spring cultivars of Kimchi cabbage(Brassica rapa L. ssp. pekinesis). We measured the weight, length, width, formation index, midrib thickness and moisture contents of fresh Kimchi cabbage for characteristics of growth. And we analyzed the free sugar, amino acid, organic acid, mineral, pectin and cellulose contents of fresh Kimchi cabbage. The hardness and firmness were measured for texture of fresh Kimchi cabbage. The weight of 'K-power' cultivar was the highest than other cultivars. The ‘Jeongsang’ cultivars was the thinnest midrib thickness in cultivars, but it was not significantly different. The free sugar levels of spring cultivars was the highest in ‘Chunkwang’. Malic acid content of ‘Jeongsang’ was significantly different among spring cultivars. Also amino acid content of ‘K-power’ and ‘Chunkwang’ were significantly different among spring cultivars Mineral content in ‘K-power’ and ‘Bomaknorang’ were greater than that of other cultivars. Especially Na, Ca and Mg contents of ‘K-power’ and ‘Bomaknorang’ were higher four times than that of other cultivars. Pectin content of ‘Jeongsang’ was higher than that of other cultivars, but it was not significantly different. Hardness and Firmness were not significantly different among spring cultivars.

이 연구는 초등학교 교감의 장학에 대한 인식에 관한 조사연구이다. 교감의 직무역할은 학교경영, 인사관리, 재정 및 사무관리, 교육계획 수립, 장학 및 교원연수, 교장ㆍ교사ㆍ행정직원간 조정자, 학생생활지도, 지역사회와 유대, 외부와 의사소통 등으로 나누어볼 수 있다. 이 중 장학 및 교원연수 역할에 대해서 응답자들은 그 중요도에 비해서 실제 수행정도는 낮은 것으로 평가하였다. 교감들의 장학에 대한 인식에 대해 분석한 결과 인식유형에 따른 2개의 하위집단이 존재함을 밝혀내었다. 이 두 집단 사이에는 교사들의 장학활동에 대한 부정적인 태도에 대한 인식의 정도와 교실운영에 있어서 교사의 자율성을 존중하는 정도에 차이가 있었다. 또한, 두 집단은 직무역할에 대해서도 학교경영과 장학활동 사이에 각기 다른 우선순위를 두는 차이가 발견되었다. 이 연구는 교감들이 학교현장에서 교육전문성을 발휘하기 위해서는 장학에 대한 인식이 비지시적이고 협동적인 접근으로 전환될 필요가 있음을 시사하고 있다.
