Alismatis Rhizoma has been used as diuretics and antiphlogistics in the Chinese oriental medicine. A trypsin inhibitor was isolated from Alismatis Rhizoma using DEAE ion exchange column, trypsin affinity column, and FPLC chromatography, and its activity and characteristics were studied. The purifed Alismatis Rhizoma trypsin inhibitor (ARTI) was estimated to be about 22 kDa. The sequence determination on N-terminal amino acid residues and 84 amino acid residues has been completed, yet no homology has been found with trypsin inhibitors reported at NCBI. ARTI did not show inhibitory activities on chymotrypsin and elastase, however it exhibited a significant inhibitory activity on bovine trypsin, and formed a complex with rat liver 10-formyltetrahydrofolate dehydrogenase.

Disintegration of Mesoporous Structures of MCM-41 and MCM-48 in Water

김지만,류룡,Kim, Ji Man,Ryu, Ryong Korean Chemical Society 1996 Bulletin of the Korean Chemical Society Vol.17 No.1

It has been found that mesoporous structures of MCM-41 and MCM-48 disintegrate readily in distilled water around 370 K, while the structures can be stable in 100%-steam of 1 atmospheric pressure at much higher temperatures around 820 K. Thus, the structure disintegration is thermodynamically more favorable in water than under the steaming condition. X-ray powder diffraction and magic angle spinning 29Si NMR spectroscopy indicate that the disintegration of the mesoporous structures in water occurs due to silicate hydrolysis.

The procedure to estimate the sources of noise and vibrations in a typical drum-type washing machine was presented. The sources should be identified to predict the radiated noise with computational model of structure. Source identification techniques based on singular decomposition were implemented using the measured signals of accelerometers and microphones. The finite element analysis and indirect boundary element analysis were implemented to predict the structural vibrations and the acoustic pressures at the field points. The predicted results by only structural sources were compared with those by both structural and acoustical sources. It was verified that not only the structural-borne source but also air-borne source should be considered to predict the radiated noise with better accuracy. The contribution analysis with respect to the transfer path was also preformed.

고독과 빈곤의 조우, 혹은 환대의 경계

이 연구는 한국 대학생의 해외봉사여행에서 맺어지는 주체와 타자의 문제를 공간성, 주체성, 관계성의 관점에서 분석하고, 그 바탕 위에서 한국 대학생의 해외봉사 활동에 내재한 주체 형성 방식에 대해 논한다. 한국 대학생의 해외봉사 활동이란 현실사회에서 자기를 스스로 이해할 수 없고 해명할 수 없으며, 자신을 설명할 언어를 획득하지 못한 ‘불투명성’에 대한 인식에서 비롯한다. 광포한 한국사회의 탐욕스럽고 비대한 타인들 사이에서, 불우한 자의 고독은 심화되고 언어는 상실된다. 불우한 주체는 자폐와 실어에 갇히게 된다. 그러한 불우한 주체에게 있어 고독을 극복하기 위한 도구이자 탈출구로서 타자가 더욱 절실히 요구되고 열망될 것이다. 이 때 여행이 제시하는 타지의 낯선 이들은 단지 미지와 신비의 대상에 그치는 것은 아니다. 고독과 고통에 매여 있었던 불우한 주체는 빈곤한 타자를 우회함으로써 자기의 존재성을 규명하고 표현할 수 있는 자기-내러티브를 만들고자 하는 것이다. 혐오와 공포와 같은 감각의 정치로부터 완전히 자유로울 수는 없지만, 봉사여행은 참여자들이 속한 사회에서 감각의 과잉과 급진화를 통해 대안적 가치를 상상하고 수행할 수 있는 장소를 만들어준다. 그 장소의 의미는 불안정성과 비고착성에 있다. 봉사활동 여행은 감각 작용을 통해 신체적으로 형성되고 써내려가는 자기-내러티브화 과정이다. 여행에서 불우한 주체는 연결/차단, 대면/회피의 경계선을 위험스럽게 맴돌고 때로는 해체 하면서 타자와의 관계 맺기를 통한 자기 형성의 기획을 조심스럽게 수행해 나간다. This study analyses self-other relations in voluntary service traveling in terms of spatiality, subjectivity and relationality. For Korean university students, their aspiration for traveling abroad, especially volunteering service in Asian developing countries, is rooted from their everyday conflict and struggle against the given neoliberal society. They can hardly fInd their own language which enables them to give account of the self, only to be doomed to autism and loss of self-language. Traveling towards the poor other becomes something, a detour through which one may escape from his/her solitude. The poor other in neibour countries is not a mystified object so much as the support for the unfortunate other to come into being and find language to express his/herself. The traveller cannot entirely free from disgust and fear for the poor other they meet during the travelling. Nevertheless, by means of facing and being mixed with the poor and sick other, s/he is enabled to create his/her own ‘place’. The unfortunate other"s traveling towards to the poor other, hence, is constitutive of the process of self-narrating.

본 논문에서는 400V, 120W 급 LED 구동을 위한 1단 전류 경계모드(Boundary Condition Mode) 제어방식의 역률 개선 제어회로를 설계하였다. 제안하는 제어회로는 역률 개선 및 고조파 발생을 감소시키는 기능을 가지고 있으 며, 또한 PFC(Power Factor Correction)회로 내에서 상대적으로 많은 면적을 차지하는 기존의 바이폴라 트랜지스터 구 조 대신 새로운 CMOS 회로로 설계하였다. 기존대비, 약 30% 정도의 레이아웃 면적을 줄이게 되었고, 상용화 시 칩 의 가격 경쟁력이 클 것으로 사료된다. In this paper, a power factor correction (PFC) control circuit using single stage boundary conduction mode(BCM) for the 400V. 120W LED drive application has been designed. The proposed control circuit is aimed for improvement of the power factor correction and reduction of the total harmonic distortion. In this circuit, a new CMOS multiplier structure is used instead of a conventional BJT(bipolar junction transistor) based multiplier where has a relatively large area. The CMOS multiplier can bring 30 % reduced chip area, competitive die cost in comparison with the conventional BJT multiplier.

In Korea, we have a own personal I.D. And, this personal I.D is able to distinguish one between other people. Especially, in the age of information society, personal information is used for commerce or financial transactions via the internet. Besides, for the using of Internet services, personal information is used as an essential element. But, despite the need for careful management of personal information, the careless management of personal information causes the Personal Information Leak. In other words, companies should manage and protect the collected personal information with the latest care, personal information may be leaked by others in any way or manner due to the failure of companies or the development of IT technology. In the wake of this Internet information age, the damage of personal information leakage is not only a domestic legal problem but also an international problem. So, we must need for comparative legal research for solving the dispute of international regal problems aobut the personal information using. As a first step, this studying examined a personal information protection act in Japan.

Purposes: This study identifies local Chinese consumers' standard for selecting medical care provider and their standard for choosing medical staff, as well as their expectations and concerns regarding Korean medical care providers. Methodology: A survey was conducted in China, to identify Chinese medical care consumers' standards for selecting a medical provider and the factors that influence their use of general hospitals. A total of 1,500 people across three cities, between the ages 18 and 60 participated in the survey. Moreover, a multiple logistic regression analysis was used to analyze the factors that affect Chinese medical care consumers' use of general hospitals. Findings: A total of 75.5 percent respondents chose general hospitals as their most frequently-used medical provider. Those who have health insurance, visit general hospitals as outpatients or are hospitalized more frequently than those who do not have a health insurance. Furthermore, those who have private insurance visit general hospitals as outpatients or are hospitalized more frequently than those who are not signed up for private insurance. Major standards for selecting a hospital included: the doctor's skills, word-of-mouth regarding the hospital, and distance to the hospital from the respondents' home. Standards for choosing medical personnel included word-of-mouth regarding the medical team, recommendations from family members or acquaintances, and medical team's notoriety. Friends and neighbors, family members, television and other media outlets were the channels for acquiring information on a hospital. It was found that Chinese people mostly visit the cardiovascular department of Korean hospitals for treatment. For using Korean hospitals in China, the majority of respondents answered that they were concerned about the cost. Practical Implications: Backed by highly skilled medical experts and cutting-edge technology, Korean medical care providers are attempting to enter China's medical care market. To succeed in China's medical care market, it is vital to conduct a clear and precise analysis.
