Objective : The purpose of this report is to use more Shin Jong Gyuk of Ohaeng Acupuncture acupunture treatment clinically by comparing the Improvement of Back pain and Sciatica between Common Acupuncture treatment Group and Common Acupuncture with Shin Jong Gyuk of Ohaeng Acupuncture treatment Group. Methods : This study was carried out on 40 patients with Back pain and Sciatica who were hospitalized in Dongshin Univ. Oriental Hospital from 1st, April, 2001 to Tenth, November, 2001. Group A of 20 patients were taken both common acupunture treatment and Shin Jong Gyuk of Ohaeng Acupuncture treatment. And Group B of 20 patients were only taken common acupunture treatment. And after 10 days of admission, we checked and compared VAS(Visual Analogue Scale) and improvement index out of these two groups. SPSS(Statistical Program for Sdcial Science) for Window was used for a statistical analysis and the independent T-test was performed to gauge the improvement of VAS(Visual Analogue Scale) and improvement index out of these two groups, in which case, value of P below 0.05 is considered as useful. Results : The result of the VAS(Visual Analogue Scale) and improvement index of comparision analysis between two groups after 10 days, shows that the improvement of Back pain and Sciatica in Common Acupuncture treatment with Shin Tong Gyuk of Ohaeng Acupuncture treatment Group is more effective than that in Common Acupuncture treatment Group. (independent T-test improvement index P=0.21, VAS P=0.00)

Since Kanda's paper on Korean scale insects in 1942, no work on scale insects has been done in Korea. The author has collected 8 species of scale insects in 5 green houses in Seoul and Suwon, of which 4 species, i.e., Chionaspis kentiae, Chrysomphalus aonidum, Planococcus kraunhiae and Aspidiotus hederae are new to Korea. Dominant species were Planococcus citri and Coccus hesperidum and common species to 4 green houses were Planococcus citri, Coccus hesperidum and Saissitia coffeae.

This paper describes an optimal configuration for multi-central inverters in a medium-voltage (MV) grid, which is suitable for large-scale photovoltaic (PV) power plants. We theoretically analyze a proposed common-mode equivalent model for problems associated with multi-central transformerless-type three-phase full bridge(3-FB) PV inverters employing two-winding MV transformers. We propose a synchronized PWM control strategy to effectively reduce the common-mode voltages that may simultaneously occur. In addition, we propose that the existing 3-FB topology may also have the configuration of a multi-central inverter with a two-winding MV transformer by making a simple circuit modification. Simulation and experimental results of three 350kW PV inverters in a multi-central configuration verify the effectiveness of the proposed synchronization control strategy. The modified transformerless-type 3-FB topology for a multi-central PV inverter configuration is verified using an experimental prototype of a 100kW PV inverter.

Objective: The purpose of this study is to evaluate the effect of auricular acupuncture therapy by using different techniques combined with common acupuncture treatment on lumbago patients. Methods: 30 patients with lumbago who were hospitalized in Semyung Univ. Oriental Medical Hospital were devided into three groups. Group A of 10 patients were treated by common acupuncture treatment and auricular acupuncture therapy by methods of burying needles. Group B of 10 patients were treatedd by common acupuncture treatment and auricular acupuncture therapy by methods of pricking needles. Group C of 10 patients were treated only by common acupuncture treatment. The pain scale and improvement index of these three groups were evaluated after 10 days of admission. Results: 1. On the score of pain scale, group A and B were both superior to group C, but had no specific difference(p=0.15). 2. On the score of improvement index, group B was superior to group A, and group A was superior to group C(p=0.04). Conclusions: The combination of auricular acupuncture therapy and common acupuncture treatment was more effective than only to use common acupuncture treatment to lumbago patients. Especially, using the auricular acupuncture therapy by pricking methods, was the most effective methods in increasing improvement index.

This The purpose of this study is to evaluate user satisfaction with village bathhouses, selected from a two-year pilot project of common facilities for senior in rural areas from 2014 to 2015. A survey was conducted using a questionnaire to evaluate user satisfaction, and 135 questionnaires were collected from 18 common meal facilities. User satisfaction was evaluated in five categories with a five-point scale: location and spatial composition; emotions and intimacy; safety; nutrition; and maintenance and management. The results are as follows. First, when overall user satisfaction was evaluated on a five-point scale, the average score stood at 4.24 out of five points and 90.03 out of 100 points. These findings suggest that users were generally satisfied with the common meal facilities. Among five categories, scores except safety stood at four points or higher, indicating higher user satisfaction. Second, communal meal in rural areas have been carried out already but the environment for communal meal like cooking equipment, wastewater disposal, and space have been poor. However, the environment is improved through this pilot project, which has a positive effect to user satisfaction. Third, space planning for barrier-free or sanitary in storage of food containers are not adequate, which is necessary to detailed planning and concrete guideline.

In Thoman and Bain and Schafer and Sheffield, procedures for testing the equality of the scale parameters of two Weibull populations with a common shape parameter and procedures for selecting the Weibull population with the largest scale parameter are given. We give, in this paper, a modified procedure for the above testing and selection problems, which is more powerful than those previoulsy given.

Common DNA fragments of the ${\beta}$-globin gene were observed from six races of the adult common carp: Hybrid-Yamato, Japanese wild type, Mirror, Suwa-Yamato, Scale German, and Saku-Yamato. Chromosomal DNAs isolated from the above six races were digested with restriction endonucleased EcoRI and PstI. The digested fragments were transferred onto nitrocellulose filter and hybridized with a probe of carp ${\beta}$-globin cDNA. Molecular sizes of the hybridized DNA fragments digested with EcoRI were 3.6Kb(Kilo base), 4.3Kb and 15Kb in Hybrid-Yamato, Japanese wild type, Mirror, Scale German and Saku-Yamato carp DNAs. In Scale German and Saku-Yamato carp DNAs, two and one more hybridized DNA fragments were observed, respectively. Molecular sizes of the hybridized DNA fragments digested with PstI were 2.2Kb, 6.5Kb, 7.8Kb and 9.2Kb in Hybrid-Yamato, 2.2Kb, 6.5Kb and 9.2Kb in Japanese wild type, 2.2Kb, 6.5Kb, 7.8Kb, and 13Kb in Mirror, 2,2Kb, 5,5Kb, 6.5Kb, 7.8Kb, 9.2Kb and13Kb in Scale German, and 2.2Kb, 5.5Kb, 6.5Kb, 9.2Kb and Saku-Yamato carp DNA. Therefore, depending on carps, three to six DNA fragments were hybridized with ${\beta}$-globin gene probe. Thus it indicated polymorphysm in the globin gene family of carp.
