The main purpose of this study is to test empirically that used theories of retailer equity and tool of retailer equity about the two of major distribution channels - discount store and on-line shopping. We used indices from Arnett, Laverie and Meiers (2003) and those factors are retailer loyalty, name awareness, service quality, retailer associations, and perceived value. For this study, we collected data from major discount stores and on-line shopping sites in South Korea. As a result, only retailer loyalty influences on retailer equity in discount store and retailer loyalty and product quality influence retailer equity. Our paper is organized as follows. First, we discussed about retailer equity and the underlying dimensions of retailer equity. Second, based on the research of Arnett, Laverie and Meiers (2003), we demonstrate a indexes of retailer equity using regression analysis for comparing discount store and on-line shopping. Third, we discuss some managerial implications of this research for retail practitioners and suggest for future research.

Background: The population of individuals classified as oldest-old (aged ≥85 years) has increased rapidly in recent years. The rates of morbidity from chronic diseases and physical dependence tend to be higher in the oldest-old compared with individuals classified as young-to-middle-old (aged 65-84 years). Therefore, the classification and evaluation of traumatic injuries in the oldest-old group are necessary. Herein we focused on the risk of traumatic intracranial hemorrhage from low-energy falls in older patients. Methods: Patient medical records from the Emergency Department after low-energy falls that occurred between November 2014 and April 2016 were retrospectively analyzed. Patients were divided into an older group (aged ≥65 years) and an adult group (aged 18-64 years); the older group was subdivided into the oldest-old group (aged ≥85 years) and a young-to-middle-old group (aged 65-84 years). The rate of intracranial hemorrhage and related factors were also investigated. Results: The older group had a greater risk of traumatic intracranial hemorrhage than the adult group (20% vs. 12.6%, p=0.019). Furthermore, more cases of traumatic intracranial hemorrhage were found in the oldest-old group than in the young-to-middle-old group (37.5% vs. 18.0%, p=0.024). Similarly, the risk of traumatic intracranial hemorrhage in the oldest-old was higher than in the young-to-middle-old group (p=0.032). Conclusion: The risk of traumatic intracranial hemorrhage from low-energy falls in the oldest-old patients was higher than in the young-to-middleold patients. Therefore, physicians need to pay particular attention to oldest-old patients, even to those with mental integrity and without neurological deficits.

Objective : The purpose of this study is to evaluate the clinical effect of the non-pharmacological anti-hypertension method, acupuncture, for hypertensive patients. Methods : 26 patients diagnosed with hypertension were each treated by one of three methods: an anti-hypertension drug(adalat soft capsule), venepuncture, and acupuncture. In cases of rising blood pressure, patients were treated by their one of the three methods, and blood pressure was measured at regular intervals. Result : As for the group of acupuncture treated patients on Young-gol(ling-gu) and Gang-ap-hyul(jiang-ya-xue), readings dropped 18.0mmHg in systolic blood pressure and 6.50mmHg in diastolic blood pressure. This was a greater effect than that seen in the venepuncture treated patients. Blood pressure checked one hour after acupuncture treatment showed a greater difference than blood pressure checked after thirty minutes. Conclusion : Safe reductions in blood pressure were observed through the non-pharmacological method of acupuncture on Young-gol(ling-gu) and Gang-ap-hyul(Jiang-ya-xue).

In the refrigerator, the two-phase refrigerant-induced noise of the capillary tube in an evaporator-inlet pipe has been a great concern. The capillary tube is usually covered with insulation-foam packed in the space between inner and outer cabinets without any vibration isolation. Therefore, the refrigerant-induced vibration of the capillary tube can be easily transferred to the outer cabinet, which may increase the radiated noise. In this paper, the characteristics of transferred vibration through the insulation-foam are investigated experimentally by using the refrigerantsupplying equipment. The frequency characteristics, such as dynamic Young's modulus and loss factor, of the insulation-foam are also discussed.

This work reports the theoretical and experimental investigations of capillary bust valves to regulate liquid flow in microchannels. The theoretical analysis uses the Young-Laplace equation and geometrical considerations to predict the pressure at the edge of the valve opening. Numerical simulations are employed to calculate the meniscus shape evolution while the interface is pinned at the valve edge. Microchannels and valves are fabricated using soft lithography. A wafer-rotating system, which can adjust the driving pressure by rotational speed, induces a liquid flow. Experimentally measured valve-bursting pressure agrees with theoretical predictions.

Background: Pityriasis versicolor(PV) is a superficial mycosis, theoretically unusual in children. Epidemiologic and clinical data for children with PV under 14 years were collected. Objective . The purpose of this study was to evaluate the clinical features of PV in the young. Method: We included all cases of PV in patients under 14 years of age observed in our department from 1981 to 1995. All cases were diagnosed on the basis of clinical criteria and were confirmed by microscopic examination. Results : From 1981 to 1995 we encountered 32 cases of PV in children, compared with 637 cases in adults; thus children represented 4.7% of all cases. The ratio of male to female was l. 7:1. Among the age groups, the incidence was the highest in the 10-14 years(43%). The monthly prevalence was the highest in August. Distribution of the lesions were the face(40.9%), neck (25%), chest(13.6%), back(11.3%), extremities(6.8%) and abdomen(2.2%). The incidence of hypopigmented lesions was 70.4% and that of hyperpigmented lesions was 29.6%. Conclusion : This study confirms that the face is a predilectionl site for PV in children and all facial lesions are hypopigmented. Other clinical features are variable and similar to those of adults. (Kor J .Dermatol 1997;35(3): 431-434)

OBJECTIVES: Recurrent respiratory papillomatosis (RRP) is caused by human papillomavirus (HPV) types 6 and 11 and is potentially preventable through vaccination. This study estimated the incidence of juvenile-onset RRP before the implementation of the national HPV vaccination program in Korea. METHODS: We conducted a cohort study using claims data provided by a mandatory insurance program to estimate the incidence of RRP and associated healthcare use. Patients with juvenile RRP were defined as those aged ≤12 years with ≥2 admissions or ≥2 outpatient visits during which they received the International Classification of Diseases, 10th revision code for benign neoplasms of the larynx (D14.1). RESULTS: During 2002-2014, 123 children (74 boys and 49 girls) were diagnosed with RRP. The patients had a mean of 6.5 person-years of follow-up. The incidence was estimated at 0.30/100,000 person-years. The median age at diagnosis was 4.0 years (mean, 4.3). Thirty-six (29.3%) patients underwent surgery, including 23 patients (18.7%) who underwent 2 or more surgical procedures. Severe disease, measured by more frequent surgical procedures and shorter time intervals between consecutive operations, was associated with a younger age at diagnosis. CONCLUSIONS: The estimated incidence of juvenile-onset RRP in Korea was similar to that reported in other countries. The RRP burden should continue to be monitored using National Health Insurance Service claims data.

Hee Jin Kim1,Hae Young Park1,Jeonga Kim1,Il Hyun Kang2,Tae Sung Kim2,Soon Young Han2,Tae Seok Kang2,Kui Lea Park2,Hyung Sik Kim1 한국독성학회 2006 Toxicological Research Vol.22 No.4
The development of in vitro assays has been recommended to screening and test-ing the potential endocrine disruptors (EDs). These assay systems focus only on identifying thethe thyroid hormone (TH) disruptors. The aim of this study was to evaluate a test system to detectTH disruptors using rat pituitary tumor GH3 cells. The test system is based on the TH-dependentincrease in growth rate. As expected, L-3,5,3-triiodothyronine (T3) markedly induced a morphologicalchange in GH 3 cells from flattened fibroblastic types to rounded or spindle-shaped types. T3 stimu-lated GH3 cell growth in a dose-dependent manner with the maximum growth-stimulating effect9 M. In addition, T3 increased the release of growth hor-mone and prolactin into the medium of the GH3 cells culture. Using this assay system, the TH-dis-rupting activities of bisphenol A (BPA) and its related compounds were examined. BPA,dimethylbisphenol A (DMBPA), and TCI-EP significantly enhanced the growth of GH3 cells in therange of 1 × 10-5M to 1 × 10-6M concentrations. In conclusion, this in vitro assay system might bestandardization before it can be used as a broad-based screening tool.
