The environmental changes in the Korean cosmetic medical service industry in the 21st century are forming intense competition among medical institutions due to the quantitative expansion of its market. For stable growth of the cosmetic medical service industry, continuous quality improvement is necessary based on empirical research on the quality of cosmetic medical services rather than external expansion. The purpose of this study is to classify the quality attributes of cosmetic medical service using Kano model and to derive the degree of satisfaction and dissatisfaction of each quality attributes through Customer Satisfaction Coefficient (CSC). Through this, the study identified strategic priorities and suggested specific step-by-step approaches and quality improvement priorities that can increase customer satisfaction using the Potential Customer Satisfaction Improvement Index (PCSI Index). Based on SERVPERF, this study used measurement tools consisting of five dimensions : tangibles, reliability, responsiveness, assurance, and empathy. In addition, it was used of measurement items reconstructed into positive, negative, and satisfaction questions for Kano model analysis, CSC analysis, and PCSI Index analysis. A total of 300 medical consumers who experienced cosmetic medical services for the past one year in medical institutions such as plastic surgery and dermatology were collected with convenient sampling. As a result, urgent items for improving the quality of service using the PCSI Index, ‘Consideration for customer benefits’ in empathy category was followed by ‘Immediate help’ and ‘Sincere response’ in responsiveness category, and ‘Understanding customer needs’ in empathy category, respectively. That is, it is required to improve human service quality attributes such as empathy and responsiveness rather than physical service quality attributes. This study contributes practically in that it provides specific and discriminatory approaches to improve customer satisfaction on cosmetic medical service quality and suggests improvement priorities.

Salicylic acid (SA) is an essential plant growth regulator that functions as a signaling molecule in plants. The purpose of this study was to clarify how the exogenous application of SA counteracts aluminum stress-induced growth and biomass yield reduction in alfalfa exposed to aluminum (Al) stress. Two-week-old alfalfa seedlings were exposed to a combination of AlCl3 (0 μM, 50 μM and 100 μM, respectively) and SA (0.1 mM) for 72 hours. We observed, Al stress-induced plant growth inhibition and forage yield reduction are Al stress-dependent manner. A significant reduction of plant height (42.0-52.9%), leaf relative water content (13.0-21.4%), root length (35.4-48.7%), shoot fresh weight (31.2-25.9%), root fresh weight (15.4-23.3%), shoot dry weight (12.7-22.2%), roots dry weight (47.3 -53.5%), were observed in alfalfa. In contrast, SA alleviated the Al-stress and enhanced growth and biomass yield in alfalfa. This study provides useful information concerning the role of SA that counteracts aluminum stress-induced growth and yield reduction in alfalfa.

Soil acidity or alkalinity are serious limitations for crop production. The purpose of this study was to clarify the negative effects of extreme pH stress (low and high) on alfalfa vegetative growth (VG) and biomass accumulation (BA). Two-week-old alfalfa seedlings were exposed to different pH (4.0, 4.5, 7.0, 8.0 and 8.5, respectively) levels for 72 hours. Alfalfa grown at pH 4.0 and 8.5 significantly reduced VG and BA, wherein as neutral pH (7.0) comparably exhibited better growth and biomass yield. These results indicate that extreme acidic or alkaline level are critical limiting factors for growth and biomass yield in alfalfa.

An 8-year-old castrated male Maltese dog (patient) was referred to our institute with refractory canine babesiosis. The patient had previously responded to conventional treatment with atovaquone and azithromycin; however, anemia had recurred at six weeks after treatment withdrawal. No effect was observed on the administration of the same medication along with diminazene aceturate. On blood analysis, mild anemia was identified, with the absolute reticulocyte count indicating a markedly regenerative state. On Diff-Quik-stained peripheral blood film examination, the parasitic protozoan Babesia gibsoni was observed, and based on further laboratory examinations, a relapse of babesiosis was confirmed. Based on a previous study of drug-resistant variants of B. gibsoni and therapeutic trials, the treatment was then changed to a combination therapy of clindamycin, doxycycline, and metronidazole. Subsequently, the patient’s condition improved rapidly — B. gibsoni was not detected in the blood film and the PCR analysis for it was negative. This treatment was discontinued at six weeks after treatment initiation; however, at seven weeks after the treatment withdrawal, another relapse of babesiosis was confirmed and treatment was restarted with the same protocol. This treatment was effective again and lasted for 12 weeks. However, anemia recurred again at five weeks after withdrawal of the previous treatment and was corrected by restarting the same treatment protocol. This third treatment continued for 24 weeks and was finally stopped at the request of the client. The patient has reportedly been doing well with no manifestation of clinical signs and symptoms. This case report demonstrates that the clindamycin- doxycycline-metronidazole combination therapy against atovaquone and azithromycin-resistant B. gibsoni may be effective in improving the clinical manifestation of symptoms of canine babesiosis and this therapy may be an alternative treatment strategy.

This study compares the differences in the gastrointestinal transit time between the conventional capsule endoscope and a minimized capsule endoscope model in normal dogs to verify whether the minimization of capsule endoscope can help relief retention in the gastrointestinal tract, especially in the pyloric passage. Three male beagles were used as the experimental group for which the minimized capsule endoscope model was orally administered and the control group consisted of three beagle dogs for which the conventional capsule endoscope was orally administered. Nine experiments were conducted with three experiments for each dog in each group. The results showed a significant difference in the gastric transit time (GTT) by the minimization of the capsule endoscope between the two groups (control group: 123.3 ± 80 min, experimental group: 63.3 ± 40.9 min, p=0.019). In contrast, the difference in the small bowel transit time (SBTT) by the minimization of the capsule endoscope between the two groups (control group: 86.6 ± 58.9 min, experimental group: 80 ± 33.5 min, p=0.863) was not significant. In this study, the capsule endoscopes reached the large intestine without retention in the small intestine in all subjects. The significant difference in the GTT between the control group using the conventional capsule endoscope and the experimental group using the minimized capsule endoscope model suggests that the smaller size of the capsule endoscope is helpful in resolving retention in the gastrointestinal tract, thus shorting the GTT.

In the Anzunbaengi (Triticum aestivum) whole wheat flour mixture group, some herbs (A [white], B [yellow], C [black], D [blue], and E [red]) were added. The physicochemical properties were compared to the strong flour and whole wheat flour mixture groups. The dry gluten content of the control group (strong flour) was 13.5±0.4%, and the content in the whole wheat flour test group was slightly lower in value than the control group. The final viscosity, breakdown, and setback values of the dough were 248.4±0.8, 104.8±0.9, and 103.1±2.9 RVU, respectively. The breakdown was significantly different in the control and whole wheat flour groups. The setback value of the dough was increased by 30 RVU in the whole wheat flour test group compared to the control group by 103.1±2.9 RVU, but there was no significant difference between the test group samples. The consistency of the control dough was 500±10 FU, and the whole wheat flour test group was significantly increased to 585±10~599±10 FU, respectively. The absorption rate was about 2% higher in the whole flour test group than in the control group (66.2±0.3%). The pH of the control paste gradually decreased with fermentation time, and the results of whole wheat flour test group were similar (5.78±0.12~5.88±0.12). As the fermentation time increased, the volume of dough was increased and the result was slightly lower in the whole wheat flour test group than in the control group.

This study is exploratory research on a relationship between changes in cultivated area of major crops and farm income by regions. We investigated level of income, volatility of income, and migration of suitable region by climate changes as factors influencing changes in cultivated area. Research processes are as follows. First, we classify the regions where cultivated areas are expanded or reduced through the trends of cultivated area by region and crop during recent 10 years. Second, we compare the changes in income related factors between groups during the same periods. Finally, the results from portfolio analysis show changes in stable income-based optimal crops. From these procedures, we found that the changes in cultivated area are not simply explained by income-related factors. In cases of vegetables, however, we also found that high volatility of income could contribute to reduce cultivated area of the crops. The results from portfolio analysis are not always consistent in all of cases. This means that crop selection can be decided by other factors than stable income.

This study aims to investigate the effect of the core capability of products in eco-friendly stores on perceived CSR and consumers’ purchasing behavior. It is also to verify the moderating mediation effect of store type (multi-category store vs. single-category store). The results indicate that generally, in eco-friendly stores, consumers perceive the core competency of the products, which increases perceived CSR and purchasing intention. In the single-category store (i.e., fashion only) compared to the multi-category store (i.e., food and fashion), consumers perceive that the core capability and CSR are higher and thus they have higher purchase intention.

본 실험은 저온처리 기간과 일장이 자생 돌마타리의 휴면타파와 생장 및 개화에 미치는 영향을 구명하기 위해 실시되었다. 노지에서 재배중인 돌마타리의 생물계절현상 반응(phenology) 을 3월부터 10월까지 조사하였다. 또한 저온처리 기간이 돌마타리 휴면타파 및 개화에 미치는 영향을 알아보기 위해 4°C 저온에 0, 3, 6, 9, 12주간 처리한 후 장일환경(16h), 25°C 온도조건에서 재배하면서 생육특성을 관찰하였다. 일장이 돌마타리의 생육 및 개화에 미치는 영향을 알아보기 위해 자연저온 처리된 돌마타리를 단일(9h), 중일(12h), 장일조건(16h)에서 재배하여 생육 특성을 관찰하였다. 야외에서 재배중인 돌마타리는 늦여름인 8월부터 9월까지 개화하는 특성을 보였다. 저온처리 기간에 따른 실험결과 9, 12주 저온처리를 받은 식물이 3, 6주간 저온처리 한 식물에 비해 개화소요일수가 유의하게 단축되었다. 돌마타리는 4°C 온도에서 9주 이상 처리시 33%의 개화율을 보이는 것으로 조사되었다. 일장에 따른 실험결과, 장일환경에서 재배된 돌마타리의 초장은 50.1cm였으나 단일 및 중일환경에서 재배된 식물의 초장은 각각 16.7, 16.1cm로 조사되었다. 돌마타리는 장일환경에서 16주간 재배 시 100% 개화하였으나 단일 및 중일 환경에서 재배 시 전혀 개화하지 않았다. 결론적으로 돌마타리 는 휴면타파 및 개화를 위해 저온을 필수적으로 요구하며 장일 환경조건에서만 개화하는 질적장일식물임을 확인하였다.

Although the use of Grammatical Metaphor (GM) has been regarded as one of the representative features of academic writing in the framework of Systemic Functional Linguistics (SFL), not many studies have explored its role in second or foreign language writers’ writing quality. This study aimed to discover the potential relationship between GM development and argumentative writing quality of advanced Korean EFL learners, while controlling for their overall language proficiency and reading comprehension ability. The findings from this study unveiled significant contribution of the use of both premature and mature GM and also identified transcategorization as the specific GM that has relatively stronger predictability of writing quality. The results from current research yield meaningful pedagogical implications for writing instruction in Korean EFL contexts.
