This study was conducted to develop functional muffin in which grape seed extract(GSE) was added at 0, 0.5, 1 or 2% levels and to evaluate the quality characteristics. The volume of muffin decreased with the increasing GSE content, but no significant differences were observed. The weight and height of muffins increased with the increasing GSE content. The incorporation of GSE in the product lowered lightness(L value) and increased redness(a value). The mechanical texture parameters including hardness, springiness, gumminess and brittleness increased with the increasing GSE levels. Sensory analysis showed that muffin prepared with 0.5% GSE was considered to be as acceptable as control, based on hedonic scale ratings given by untrained taste panel.

최혜민(Hai Min Choi),명기범(Ki Bum Myung),국홍일(Hong Il Kook) 대한피부과학회 1983 대한피부과학회지 Vol.21 No.2

Cutaneous leishmaniasis (oriental sore) is usually a self-limited infection of the skin caused by the protozoan Leishmania tropica. The disease is endemic to the Mediterranean, Asia, Africa, and the Middle East. It has been seen in this country among many Korean technical experts and labourers working in the endemic areas of the disease. Our patient had acquired cutaneous leishmaniasis in Saudi Arabia and it had remained active for six months. He had been treated with antimony and metronidazole but failed because of severe side effects. And then we treated the patient witb cryosurgery and the skin lesions were followed by resolution with cosmetically acceptable scar in 4 months. The brief review of literature on the treatment of cutaneous leishmaniasis was undertaken.

Aplasia cutis congenita is an anomaly characterized by absence of localized areas of the integument. The most common type of aplasia cutis congenita is a circular or oval, sharply outlined ulcer 1 to 3cm in diameter on the vertex of the scalp at the level of the posterior fontanel. Two cases of aplasia cutis congenita are presented. The first case was in a male newborn infant with a localized defect on his scalp. The second case was also in a male newborn infant who had extensive symmetrical involvement of his heels. No similar conditions and associating other congenital anomalies were found in the family members of reported cases.

Effects of Addition of Herbs on Pork Patties during Storage

( Min Hee Choi ),( Hai Jung Chung ) 한국식생활문화학회 2009 Food Quality and Culture Vol.3 No.2

This study was conducted to investigate the effects of herbs (dill weed, fennel seed and rosemary) on color stability and lipid oxidation of ground pork patties during storage at 2oC and -20oC. Lipid oxidation was determined by the thiobarbituric acid reactive substances (TBARS) method. Fennel seed was identified as being the most effective ingredient in terms of meat redness (Hunter a-values) during storage at 2oC (p<0.05). Patties treated with rosemary had lower Hunter a-values than control, and dill weed was the least beneficial in influencing meat redness, having significantly lower a-values than control patties. During frozen storage at -20oC, no significant differences in a-values were observed between the control patties and those treated with fennel seed. Patties treated with rosemary had lower a-values than control and patties with dill weed had negative a-values throughout storage. The cooking process increased Hunter L-values and decreased a-values in all patty samples. TBARS values increased during storage. Rosemary displayed excellent antioxidative activity as evidenced by the completely inhibition of TBARS formation of cooked pork patties. Dill weed and fennel seed also exerted an intermediate but significant antioxidant effect during storage (p<0.05).

Hai Xia Su,김진민(Jin Min Kim),김영대(Young Dae Kim),최성용(Sung Yong Choi) 중앙대학교 한국전자무역연구소 2017 전자무역연구 Vol.15 No.2

연구목적: 본 연구는 중국 소비자들을 대상으로 O2O 서비스에서 Kano 모형을 이용해 서비스 품질을 분류하고, 고객만족계수와 불만족계수를 각각 산출하였다. 이후 순차적으로 잠재적 고객만족개선지수(PCSI Index)를 산출하였다. 그 결과 O2O 서비스 제공 시 우선적으로 고려하여 관리 및 개선해야 할 서비스 품질속성을 판단하고, 최종적으로 중국 소비자들의 고객만족을 높일 수 있는 우선적인 개선사항들을 제시하고자 한다. 논문구성/논리: 본 논문은 전체 5절로 구성되어 있다. 1절에서는 연구의 배경 및 방향에 대하여 제시한다. 이 후 2절에서는 관련 문헌에 대하여 검토한다. 3절에서는 연구모형과 연구방법을 제시하고, 4절에서는 연구방법을 통해 도출된 결과를 분석하였다. 최종적으로 5절에서는 결론을 도출하고, 연구의 시사점 및 한계점을 설명한다. 결과: 첫째로 중국 소비자들을 대상으로 하는 기업에서는 본 연구에서 확인된 당연적 품질요소나 일원적 품질요소 이외에도 이러한 매력적 품질요소에 투자를 하고 꾸준한 관리를 해야 한다. 둘째로 PCSI 지수 값이 높을수록 고객의 만족도를 증가시킬 수 있는 요인들이다. 따라서 지수 값이 높게 나온 요인들을 중점적으로 개선한다면 고객들의 만족도가 크게 증가할 것이다. 마지막으로 PCSI지수의 상위에 위치한 항목들은 개선이 가장 시급하고 고객만족이 가장 크게 증가될 수 있다. 따라서 이와 같은 항목에 투자하여 소비자들을 끌 수 있도록 해야 할 것이다. 독창성/가치: 본 연구는 중국 소비자들을 대상으로 O2O 서비스 품질을 Kano 모형에 따라 매력적 품질, 일원적 품질, 당연적 품질, 무관심 품질, 역 품질로 분류하였다. 이 후 고객만족계수를 이용하여 품질 요인들 중 고객의 만족도의 상승가능여부 또는 하락가능여부를 파악하고 잠재적 고객만족 개선지수(PCSI index)를 산출하였다. 이로써 고객만족을 높이기 위해 우선적으로 개선되어야 하는 품질 요인들이 결정되었다. 따라서 본 연구에서는 Kano 모형과 PCSI 지수를 기반으로 O2O 서비스 품질에 관한 고객만족을 높일 수 있는 우선적인 개선사항들이 효과적으로 제시되었다. Purpose: In our study, we classify the quality factors involved in the online to offline (O2O) service to Chinese consumers by using the Kano model and calculate the customer satisfaction and dissatisfaction coefficients. Next, we calculate the PCSI (Potential Customer Satisfaction Improvement) index. As a result, we determine the service quality attributes in O2O service that should be managed and improved first, and finally present some preemptive improvements that will enhance customer satisfaction among Chinese customers. Composition/Logic: This paper has five sections. In section 1, we present the objectives and overview of the study. We review related literature in section 2. We describe our research model and methodology in section 3 and analyze the results in section 4. In section 5, we draw conclusions from the study, and explain both the implications and limitations of the study. Findings: First, in the companies targeting Chinese consumers, the attractive quality factors, which are identified in this study, should be invested in and maintained at a constant level, along with the must-be and one-dimensional quality factors. Second, the higher the value of PCSI index, the more likely is the increase in the satisfaction of the customer. Thus, customer satisfaction will increase significantly if we focus on the factors that have high PCSI index values. Third, the top ranked items in the PCSI index are the quality factors that not only need the most urgent improvement but can also increase customer satisfaction the most. Therefore, consumers should be attracted by investing in these items. Originality/Value: This study categorizes O2O service quality into attractive quality, one-dimensional quality, must-be quality, indifferent quality and reverse quality by applying the Kano model to Chinese consumers. We then use the customer satisfaction coefficient to determine whether the customer s satisfaction level could increase or decrease and calculate the Potential Customer Satisfaction Improvement index (PCSI index). This has led to the identification of quality factors that should be improved first to improve customer satisfaction. Therefore, in this study, based on the Kano model and the PCSI index, the priority improvements that can improve customer satisfaction on O2O service quality are presented effectively.

Over-exposure to sunlight may result in sunburn, pigmented skin lesions, solar keratosis, premature aging of skin, or cancer in human skin. Sunscreens protect the structure and function of the human integument from the actinic damage. This protective effect is afforded by active ingredients of sunscreens through absorption, reflection, and/or scattering of the solar radiation impinging on the skin. There are oral and topical sunscreens. Para-aminobenzoic acid(PABA), PABA esters, benzophenones(BZ), cinnamates, salicylates and anthranilates are the topical sunscreens absorbing solar radiation. Most of them absorb UVB, but BZ absorb both UVB and UVA. These investgators observed the effect of the sunscreens by calculating sun protection factor(SPF) before and after application of the sunscreens in human skin. To my knowledge, there are no papers which evaluate morphological changes in the epidermal melanocytes after UVB or UVA irradiation following application of the sunscreens. In this experiment, a total of 150 adult male black mice(C57BL) was used. The animals were divided into one control (application of hydrophilic ointment base) and four experimental(application of PABA, Cinnamate, BZ or homomenthylsalicylate (HMS)) groups. Each group was irradiated by UVB and UVA, respectively. Each of the 5 groups were divided into 5 subgroups according to the days of UV light irradiation ; subgroup A for 2 days, B for 4 days, C for 6 days, D for 8days and E for 10 days. The daily doses of UVB and UVA were 50mJ/cm^2 and 5J/cm^2 respectively. YS UVB-400 and Waldmann UV 800 were used as a light source of UVB and UVA. Skin specimens were taken from both ears of the animals 24h after the last irradiation. The split-DOPA preparation was carried out for observation of the numbers and morphological changes of the epidermal melanocytes. The results are summarized as follows; 1. Changes in the numbers of the epidermal melanocytes : The numbers of the epidermal melanocytes markedly decreased in the experimental groups, especially in the group of PABA application(p<0.01), compared in the control group under UVB irradiation (p<0.01). However, only the group of BZ application showed a significant decrease in the numbers compared to the control group under UVA irradiation(p<0.01, p<0.05). 2. Changes in the size of the epidermal melanocytes ; Each experimental group, especially the group of PABA application (p<0.01), showed a significant decrease in the sizes of the epidermal melanocytes under UVB irradiation(p<0.01, p<0.05). On the other hand, only the group of BZ application showed a significant decrease in the sizes compared to the control group under UVA irradiation(p<0.05) From the results, it seems to be sure that PABA, Cinnamate, BZ, HMS can protect UVB from sunlight in the skin of black mice. Furthermore, BZ was effective for protection of UVB and UVA together.
