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.

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.

폴리(글리시딜 메타크릴레이트)가 그래프트된 다중벽 탄소나노튜브에 다양한 아민 그룹의 도입과 바이오센서 지지체로서의 응용

정다정(Da Jung Chung),김기출(Ki Chul Kim),최성호(Seong Ho Choi) 한국고분자학회 2012 폴리머 Vol.36 No.4

다양한 아민 그룹으로 개질된 다중벽 탄소나노튜브(이하 MWNT) 지지체를 기반으로 하여 페놀 화합물을 검 출하기 위한 티로시나아제가 고정된 바이오센서를 개발하였다. 방사선 중합법을 이용하여 MWNT에 글리시딜메타 크릴레이트를 중합한 후 중합 사슬의 아미노화 반응을 통해 MWNT에 다양한 아민 그룹을 도입시켰다. 이렇게 제조된 물질의 물리적, 화학적 특성은 SEM, XPS 그리고 TGA에 의해 평가되었다. 그리고 제조된 물질을 기반으로 제작된 티로시나아제가 고정화된 바이오센서의 전기화학적 특성도 평가하였다. 본 효소 바이오센서는 0.1-0.9mM의 페놀을 검출할 수 있다. 결합효과, pH, 온도 그리고 다양한 페놀화합물에 대한 반응과 같은 여러 가지 변수에 대하여도 최적화하였고 상용 레드와인에서의 페놀화합물 검출도 연구하였다. A tyrosinase-immobilized biosensor was developed based on various amine-modified multi-walled carbon nanotube (MWNT) supports for the detection of phenolic compounds. MWNTs with various amine groups were prepared by radiation-induced graft polymerization of glycidyl methacrylate (GMA) onto MWNT supports and the subsequent amination of poly (GMA) graft chains. The physical and chemical properties of the poly (GMA)-grafted MWNT supports and the aminated MWNT supports were investigated by SEM, XPS, and TGA. Furthermore, the electrochemical properties of the prepared tyrosinase-modified biosensor based on MWNT supports with amine groups were also investigated. The response of the enzymatic biosensor was in the range of 0.1-0.9mM for the concentration of phenol in a phosphate buffer solution. Various parameters influencing biosensor performance have been optimized: binder effects, pH, temperature, and the response to various phenolic compounds. The biosensor was tested on phenolic compounds contained in two different commercial red wines.
