The purpose of this study was to investigate service quality of department stores located in Daegu and to examine the effects of service quality on customer satisfaction and store patronage. Data(N=285) were analyzed, using factor analysis, 1-test, ANOVA and regression analysis. The results suggest that service quality was divided into 3 dimensions (reliability, tangibles, empathy) and that service quality enhanced customer satisfaction and store patronage. Specifically, tangibles had a positive effect on customer satisfaction, and reliability had a positive effect on store patronage. Also, personal characteristics were related to service quality, customer satisfaction and store patronage. For instance, male customers evaluated tangibles of service quality more positively than female customers. The married evaluated service quality, customer satisfaction and store patronage more positively than the single. While people aged above 36 yews evaluated reliability and empathy of service quality more positively than people aged below 35 years, people in their 20s evaluated tangibles more positively than people in their 30s. People in a higher income bracket (i. e., \301,000,000- \400,000,000) evaluated reliability and empathy of service quality and store patronage most positively, while people in a lower bracket (i. e., below \200,000,000) evaluated most negatively.

The purpose of this research was to investigate the effect of the desired sportswear benefits on the sportswear image preferences and store patronage according to store type. The subjects were 773 male and female consumers who were residents in Seoul. The data were analyzed by factor analysis, multiple regression, and t-test. The results showed that there were five desired sportswear benefits: figure compensation, status ostentation, comfort, individuality, and youth-orientation. Sportswear image preferences consisted of four factors: innovative, luxurious, simple, and active. Store patronage encompassed department store, franchise store, discount store, wholesale store, internet, TV home shopping, and catalogue. Statistical analysis showed that there were significant effects of desired sportswear benefits on sportswear image preferences and store patronage. For example, the more consumers desired figure compensation/sex appeal benefits from sportswear, the more they preferred innovative, luxurious, and active sportswear images and the stronger was their patronage of department stores. The study also showed differences between male and female consumers in regard to sportwear benefits sought and store image preferences. The implications of the research were discussed.

In this study, we produced iron-fortified yeast (Saccharomyces cerevisiae) producing Sus scrofa ferritin heavy-chain to provide iron supplementation in anemic piglets. We determined whether iron-ferritin accumulated in recombinant yeasts could improve iron deficiency in mice. C57BL/6 male mice exposed to Fe-deficient diet for 2 weeks were given a single dose of ferrous ammonium sulfate (FAS), ferritin-producing recombinant yeast (APO), or APO reacted with iron ($Fe^{2+}$) (FER). The bioavailability of recombinant yeasts was examined by measuring body weight gain, hemoglobin concentration and hematocrit value 1 week later. In addition, ferritin protein levels were evaluated by western blot analysis and iron stores in tissues were measured by inductively coupled plasma spectrometer. We found that anemic mice treated with FER exhibited increased levels of ferritin heavy-chain in spleen and liver. Consistently, this treatment restored the iron concentration in these tissues. In addition, this treatment significantly increased hemoglobin value and the hematocrit ratio. Furthermore, FER treatment significantly enhanced body weight gain. These results suggest that the iron-fortified recombinant yeast strain is bioavailable.

안경원은 소매점포의 특성들을 가지고 있다. 시장에서 이러한 안경원들간의 경쟁 또는 갈등의 야기는 경쟁 당사자들에는 물론 원재료 공급업자들이나 궁극적으로는 소비자 모두에게 손실을 가져다주게 된다. 따라서 이러한 비효율적 경쟁은 바람직하지 못하다. 이러한 문제점들을 어느 정도 해결해 줄 수 있는 개념으로서 전략적 제휴의 개념을 들 수 있는데, 모든 안경원들은 이러한 개념들의 도입 및 적용을 적극적으로 고려하여야 할 것이다. 물론 지금까지의 전략적 제휴에 관계된 내용들은 주로 일반 기업들에 적용되는 개념들로서 소매점포의 형태를 띠고 있는 안경원에는 다소 적용상 문제점이 있을 수 있다. 그러나 그 기초적인 개념의 적용은 현실적으로 가능하고 이 개념을 안경원에 적용 발전시킬 경우 매우 큰 효과가 기대된다.

Two components of the neuroendocrine-hormonal response to long-term treatment of acarbose, adipose tissue-derived leptin and central neuropeptide Y (NPY), were investigated in the ICR mice on a high- carbohydrate diet. Acarbose, administered 5 or 50 mg per 100 g diet for four weeks, dose dependently suppressed body weight gain. The body weight gain was reduced along with the amount of daily food intake in 50 mg acarbose-treated group at $7^{th}\;and\;28^{th}$ day. 5 or 50 mg acarbose treatment administered for four weeks reduced leptin mRNA levels to 62% and 77% of the control group, demonstrating that the amount of leptin mRNA in adipocytes correlates with body weight. As dose of acarbose increased, leptin mRNA level also increased, suggesting that potent inhibition of ${\alpha}-glycosidase$ by a higher dose of acarbose furthers the enzyme activity and leptin gene consequently. On the other hand, central expression level of NPY gene was increased significantly compared with the control group at the same amount of acarbose administered, reflecting that leptin and NPY operate in a negative-feedback circuit to regulate body fat stores.

Purpose - This study aims to develop and empirically test a multi-dimensional service convenience scale with the dimensions and measurement items of service convenience perceived by Korean consumers in retail contexts. Research design, data, and methodology - The study adopts the framework suggested by Berry et al. (2002) and conceptualizes service convenience as a second-order reflective construct comprising 31 items. Three department store chains (Hyundai, Lotte, and Shinsegae) and three discount store chains (E-mart, Homeplus, and Lotte Mart) were involved 510 valid responses were used for the empirical testing. Results - The measurement model is acceptable for internal consistency, convergent validity, and discriminant validity. Further, the structural model results show that service convenience is positively related to satisfaction. Results of the rival model comparison indicate that the proposed second-order factor model provides a better fit to the data than both the five-factor and the one-factor model. Conclusions - The multi-dimensional, second-order conceptualization of service convenience is robustly supported. This study provides psychometrically valid scales to measure service convenience in retail contexts as conceptualized by Berry et al. (2002).

The role of phospholipase ($A_2\;PLA_2$) in tumor cell growth was investigated using SK-N-MC human neuroblastoma cells. 4-Bromophenacyl bromide (BPB) and mepacrine (Mep), known $PLA_2$ inhibitors, suppressed growth of the tumor cells in a dose-dependent manner without a significant cytotoxicity. Melittin (Mel), a $PLA_2$ activator, enhanced the cell growth in a concentration-dependent fashion. The growth-enhancing effects of Mel were significantly reversed by the co-treatment with $PLA_2$ inhibitors. In addition, Mel induced intracellular $Ca^{2+}$ release from internal stores like as did serum, a known intracellular $Ca^{2+}$ agonist in the tumor cells. Intracellular $Ca^{2+}$ release induced by these agonists was significantly blocked by $PLA_2$ inhibitors at growth-inhibitory concentrations. Arachidonic acid (AA), a product of the $PLA_2-catalyzed$ reaction, induced cell growth enhancement and intracellular $Ca^{2+}$ release. These effects of AA were significantly blocked by BAPTA/AM, an intracellular $Ca^{2+}$ chelator. Taken together, these results suggest that the modulation of $PLA_2$ activity may be one of the regulatory mechanisms of cell growth in human neuroblastoma cells. Intracellular $Ca^{2+}$ may act as a key mediator in the $PLA_2-induced$ growth regulation.

Supplying clean and safe water to people is facing both quantitative and qualitative challenges. Due to climate change, access to freshwater becomes increasingly difficult, while pollution from various sources decreases the public trust in water quality. Managed aquifer recharge (MAR) which stores and uses surface water in aquifer is receiving attention as a new technology to secure freshwater. Recently, there is a global expansion in the attempt to combine general purification plants and hazard analysis and critical control point (HACCP) which manages all the process from raw material to consumer for food safety. This research is about an attempt to apply HACCP to the drinking water supply process using MAR to secure both quantity and quality of drinking water. The study site is a MAR plant being constructed in the downstream area of the Nakdong River Basin, South Korea. The incorporation of HACCP with MAR-based water supply system is expected to enhance the safety and reliability of drinking water.

This paper investigates the reaction rates of $CO_2$ that stores carbonation through comparing the carbonation behavior between $Ca(OH)_2$ and fly ash with circulating fluidized bed combustion (CFBC) containing a large amount of free CaO. Because fly ash with CFBC contains abundant free CaO, it cannot be used as a raw material for concrete admixtures; hence, its usage is limited. Thus, it has been buried until now. In order to consider its reuse, we conduct carbonation reactions and investigate its rates. X-ray diffraction (XRD), thermogravimetric/differential thermal analysis (TG/DTA), and X-ray fluorescence (XRF) are conducted for the physical and chemical analyses of the raw materials. Furthermore, we use a PH meter and thermometer to verify the carbonization rates. We set the content of the fly ash of CFBC, $Ca(OH)_2$, $CO_2$ flow rate, and water to 100 ~ 400 g, 30 ~ 120 g, 700 cc/min, and 300 ~ 1200 g, respectively, based on the content of the free CaO determined through the TG/DTA analyses. As a result, the carbonization rate of the fly ash with CFBC is the same as that of $Ca(OH)_2$, and it tends to increase linearly. Based on these results, we investigate the carbonization behavior as a function of the free CaO content contained in the raw material.
