Objectives : The 7-zone-diagnostic system is a device for predetermining bodily locations by measuring the energy of the living body. The purpose of this study is to examine correlations between gastroscopy results and zone-5 data from the 7-zone-diagnostic system. Methods : This study was carried out with data from gastroscopy procedures. It involved 115 patients who had been diagnosed with gastritis, esophagitis, or gastric ulcers. These patients were divided into three groups according to the different patterns of zone-5 factors AA, FL2 and FL1. Group A was made up of patients for whom the red bar graph of zone-5 was higher than the normal range for factor AA. Group B was made up of patients for whom the red bar graph of zone-5 was within the normal range for factor AA. Group C was made up of patients for whom the red bar graph of zone-5 was lower than the normal range for factor AA. Group D E and F were made up of same way as group A B and C for factor FL2. Group G H and I were made up of same way as group A B and C for factor FL1. After the collection of gastroscopy results and data on zone-5 from the 7-zone-diagnostic system, the data was analyzed statistically. Results : 1. Group D had a higher ratio of medication than group E, and this result was statistically significant. 2. Group D G had a higher ratio of medication than group E G and group E H, and this result was statistically significant. 3. Group G had a higher ratio of esophagitis than group H, and this result was statistically significant. 4. A Group B H had a higher ratio of esophagitis than group B G, group C G, and group C H, and this result was statistically significant. 5. The medication group had a high score on the function index than the non-medication group, and this result was statistically significant. Conclusions : This study suggests that there is a slight correlation between gastroscopy results and zone-5 data from the 7-zone-diagnostic system. The research resulted in significant data that are helpful for diagnosing digestive system problems through the use of the 7-zone-diagnostic system.

Natural ecosystem is an essential part to connect with the plan for biodiversity conservation in response strategy against climate change. For connecting biodiversity conservation with climate change strategy, Europe, America, Japan, and China are making an effort to discuss protection necessity through national biodiversity valuation but precedent studies lack in Korea. In this study, we made biodiversity maps representing biodiversity distribution range using species richness in National Forest Inventory (NFI) and Forest Description data. Using regression tree algorithm, we divided various classes by decision rule and constructed biodiversity maps, which has accuracy level of over 70%. Therefore, the biodiversity maps produced in this study can be used as base information for decision makers and plan for conservation of biodiversity & continuous management. Furthermore, this study can suggest a strategy for increasing efficiency of forest information in national level.

This study tested the anti-inflammatory and anti-melanogenic effects of an ethanol extract of Orostachys japonicus, a herb used as a folk remedy for cancer for a long time. To assess the anti-inflammatory effect of the O. japonicus ethanol extract (OJE), we treated the RAW 264.7 macrophagocytic cells with the pro-inflammatory mediator lipopolysaccharide (LPS) alone and with LPS and OJE together, then measured NO generation. OJE significantly reduced inflammation in a dosedependent manner. To assess the anti-melanogenic effect of OJE, melanin biosynthesis in B16F10 cells was evaluated. OJE significantly inhibited melanin biosynthesis in a dose-dependent manner. In a clinical experiment, a group of subjects who used a cosmetic product containing OJE (experimental group) for 4 weeks showed a significant reduction in the melanin indices of the forehead, left cheek, and chin compared to those of the control group. The experimental group showed a significant reduction in transepidermal water loss of the left cheek and chin. A statistically significant reduction in the erythema indices of all the regions examined except the right cheek in the experimental group also observed. Base on the results, OJE could be used as a natural cosmetic material.

전후 한국 농촌개발에 대한 미국의 관점 분석

정다정(Da-Jung Jung),변수진(Soojin Byun),김봉관(Bongkwan Kim),유성상(Sung-Sang Yoo) 한국농촌사회학회 2018 農村社會 Vol.28 No.2

이 연구는 1958년부터 1964년까지 미공보원에 의해 간행된 『새힘』에 대한 질적 내용분석을 통해 『새힘』에서 기술된 한국 농업, 농민, 농촌에 대한 인식을 고찰하고, 그 함의를 필립 맥마이클의 ‘개발 프로젝트’의 주요 구성요소를 중심으로 분석하였다. 그 결과, 『새힘』은 미국의 전후 국제전략의 맥락에서 한국 농촌지역을 중심으로 집행된 미국의 대외원조 정책을 홍보하는 기제가 되었으며, 화학비료와 기계화의 장려를 통해 농업의 산업화를 지원하였으며, 한국 농촌사회의 전통적 지식보다 합리성과 과학적 진보에 기반을 둔 개발과 생활 수준의 향상을 부각하였음을 파악하였다. 또한 『새힘』의 내용은 한국 농촌사회를 중심으로 이루어졌던 개발이 젠더 불평등을 강화하고 있음을 보여주었다. 마을 주민들의 자조적 노력과 지역개발의 주체로서 농촌 청년들의 역할 또한 강조하고 있으나, 이들이 이루어야 하는 것으로 가정하는 발전도 현대화와 합리성에 기반을 두고 있는 것으로 볼 때 『새힘』의 관점은 국제전략으로서 개발 프로젝트를 설명한 맥마이클의 주요 논지와 연계성을 가진다. This paper examines the perception of Korean agriculture, farmers, and rural areas described in New Strength, the monthly magazine published by USIS from 1958 to 1964. It draws its implications from Philip McMichael"s "Development Project" through the qualitative content analysis of New Strength. The results show that New Strength became a mechanism to promote U.S. foreign policies implemented in Korean rural areas in the context of the U.S."s postwar international strategy. Besides, its content supported the industrialization of agriculture through the promotion of chemical fertilizer and mechanization. New Strength also emphasized the development of living standards based on rationality and scientific progress rather than the traditional knowledge of Korean rural society. In addition, the contents of New Strength show that rural development in Korea led to reinforcement of gender inequality. Although it emphasized self-motivated efforts of the villagers and the role of rural youth as a subject of rural development, the development they tried to achieve is based on modernization and rationality. In these regards, the perspective of New Strength is closely linked to the main arguments of McMichael"s development project described as an international strategy.
