Control degree and property changes of dissolved organic matter (DOM) were conducted by coagulation of chemical treatment for 2 sewage treatment plants with different technical methods. As the result, SUVA value of the second treated water (supernatant of the second settling pond after biological treatment) was increased and DOC was reduced in comparison with supplied raw water. And, SUVA value and DOC were reduced by coagulation after coagulation treatment of the second treated water. Properties of dissolved organic matter for 2 sewage treatment plants's DOC were divided. As the result, there was lots of hydrophilic component with hydrophilicity in case of plant A. In case of the second treated water, Plant A showed fulvic acid with little molecular weight was reduced among the hydrophobic component with hydrophobicity, but numic acide with lots of molecular weight was increased. However, in case of plant B, both fulvic acid with little molecular weight and humic acid with lots of molecular weight were increased among the hydrophobic components with hydrophilicity. Before the operation of phosphorus facility, properties of dissolved organic matter after biodegradation with effluent water showed hydrophilic components were reduced and hydrophobic components were increased. However, after coagulation treatment of the second treated water, hydrophilic components and hydrophobic components were outstandingly decreased or increased. During the biodegradation after coagulation treatment, hydrophilic components were significantly decreased and hydrophobic components were increased.

온라인 의료광고를 통해 본 성의 의료화 : 여성 및 남성 의원의 성기성형 광고홍보물을 중심으로

본 연구는 의료법 개정 이후 급증해온 여성의원 및 남성의원의 온라인 의료광고에 대한 담론분석을 통해 사회역사적 구성물로서의 성(性)의 의료화와 성별 고정관념을 고찰하였다. 연구자료는 국내 3대 포털사이트에서 ‘여성의원’ 및 ‘남성의원’을 검색하여 우선순위 및 적극성을 고려해 선정된 총 14곳(여성의원 6곳, 남성의원 8곳) 의원 웹사이트의 성기성형 의료광고물이다. 연구방법은 비판적 담론분석과 여성주의 질적 내용분석법을 활용하였다. 연구결과, 의원 웹사이트의 성기성형 광고홍보물은 공통적인 ‘의료광고를 통해 표상되는 성의 의료화’와 성별에 따라 ‘의료광고를 통해 확대 재생산되는 성차별적 고정관념’이라는 두 영역으로 나누어 의료사회학적으로 해석할 수 있었다. 본 연구는 성이의료화되는 양상과 그 과정에서 영속화될 수 있는 성별 규범을 확인하였다는 데에서 의의를 찾을 수 있다. 의과학의 권위는 의료광고를 개인의 건강과 직결시킴은 물론 성적인 몸을 상업적으로 의료화하며 사회의 성차별을 정당화하는 성차를 재생산할 수 있으므로, 이에 대한 사전심의 및 사후관리가 요구된다. Since the revision of Korean Medical Law, online medical advertisements have continued to increase. This paper examines the medicalization of sex and gender stereotypes embedded in such advertisements, focusing on female/male genital cosmetic surgery. Fourteen clinic websites that actively advertise these surgeries were selected for critical discourse and qualitative content analysis from feminist perspective. The first part of this paper looked at the medicalization of sexuality through genital cosmetic procedures in general. The second part examines the gender differences in that medicalization through the advertisements: hymen reconstruction regarding the ideology of virginity, penile enlargement with phallocentrism. Considering advertisements may reflect and perpetuate what society desires, this paper concluded with a few suggestions on medical advertisements system.

재사용성과 확장성있는 HL7 인코딩 / 디코딩 프레임워크의 설계 및 구현

김정선(Jungsun Kim),박승훈(Seung-Hun Park),나연묵(Yunmook Nah) 한국정보과학회 2002 정보과학회 컴퓨팅의 실제 논문지 Vol.8 No.1

HL7 (Health Level 7)은 Healthcare 환경의 이질적 시스템간에 임상 및 관리정보의 교환을 가능하게 하는 국제 표준 프로토콜로서 표준 인코딩 규칙에 따른 다양한 HL7 메시지 양식을 정의하고 있다. 본 논문에서는 메시지 객체 모델(Message Object Model)과 메시지 정의 저장소(Message Definition Repository)를 이용하여 유연성, 재사용성, 확장성이 탁월한 HL7 인코딩/디코딩 프레임워크의 설계 및 구현을 제시한다. 메시지 객체 모델은 HL7 메시지를 구성하는 객체들과 그들 간의 다양한 관계를 나타내는 추상적 HL7 메시지 양식으로서, 세그먼트, 필드, 컴포넌트 등과 같은 HL7 메시지의 표준 구성요소들 간의 논리적 관계를 반영하는 동시에 표준안에 의해 규정된 구조적 제약사항을 만족하도록 하여 준다. 메시지 객체 모델은 플랫폼 종속적인 데이터 양식과 상관 없이 독립적으로 HL7 인코더와 디코더를 구축할 수 있도록 하여 주기 때문에 최소의 노력으로 임의의 이질적 병원 정보 시스템들을 상호 연결할 수 있도록 한다. 한편, HL7 메시지들을 정의하고 있는 외부 데이터베이스인 메시지 정의 저장소는 표준 HL7 메시지 양식이 수정되더라도 인코더와 디코더의 구현이 영향을 받지 않게 하여 준다. 게다가, 메시지 정의 저장소는 인코더와 디코더 각각의 입력(즉, 메시지 객체 모델로 표현된 HL7 메시지 객체와 인코딩된 HL7 메시지 문자열)에 대하여 합법성 여부를 조사하는 데 유용하게 사용된다. 본 논문에서는 프로토타입 HL7 인코더와 디코더의 구현을 위해 JAVA를 이용하였지만, 제시된 인코딩/디코딩 프레임워크는 인코더와 디코더를 ActiveX, JAVABEAN 또는 CORBA 객체 등과 같이 독립된 표준 컴포넌트로서 쉽게 구현될 수 있도록 하여 준다. The Health Level Seven (HL7), an international standard for electronic data exchange in all healthcare environments, enables disparate computer applications to exchange key sets of clinical and administrative information. Above all, it defines the standard HL7 message formats prescribed by the standard encoding rules. In this paper, we propose a flexible, reusable, and extensible HL7 encoding and decoding framework using a Message Object Model (MOM) and Message Definition Repository (MDR). The MOM provides an abstract HL7 message form represented by a group of objects and their relationships. It reflects logical relationships among the standard HL7 message elements such as segments, fields, and components, while enforcing the key structural constraints imposed by the standard. Since the MOM completely eliminates the dependency of the HL7 encoder and decoder on platform-specific data formats, it makes it possible to build the encoder and decoder as reusable standalone software components, enabling the interconnection of arbitrary heterogeneous hospital information systems (HISs) with little effort. Moreover, the MDR, an external database of key definitions for HL7 messages, helps make the encoder and decoder as resilient as possible to future modifications of the standard HL7 message formats. It is also used by the encoder and decoder to perform a wellformedness check for their respective inputs (i.e., HL7 message objects expressed in the MOM and encoded HL7 message strings). Although we implemented a prototype version of the encoder and decoder using JAVA, they can be easily packaged and delivered as standalone components using the standard component frameworks like ActiveX, JAVABEAN, or CORBA component.

Today's modern engines are designed for higher Power and Engine speed, thus optimized concerning the dimensions of engine bearings in terms of low friction and sufficient bearing oil pressure. Oil aeration is the process by which air is circulated through, mixed with or dissolved in a liquid or substance. Oil aeration measuring methods are only capable to determine the share of dissolved (free) gas in the Common-Rail Direct Injection Diesel Engine Oil(Lubricant). The effects of oil Aeration on engine drive causes malfunctions of several components. The high oil aeration can cause hydraulic lash adjuster malfunction and connecting rod bearing failure. A successful optimization of the oil circulation concerning the oil aeration presupposes a safe and reproducible measuring procedure. This paper results of recent research and development work concerning the occurrence of oil aeration within the lubricant system of New Development Engine.

본 연구는 공적 사과문 텍스트의 위기 유형별 구조와 언어 표현을 분석하는 데에 목적이 있다. 위기 유형은 ‘사고, 실수, 위반’으로 구분하여 참여자 구조와 사과 내용 설명, 사과 표현, 문제 해결 방안, 재발 방지 약속 등의 내용 구조를 중심으로 살펴보았다. 분석 결과 참여자 구조 중 발신자는 ‘사고’와 ‘위반’이 기관명, 기관 대표자 등의 이름이 다수였으며, ‘실수’는 개인의 이름이 주를 이루었다. 수신자는 피해자가 개인일지라도 사과문에서는 개인과 집단 모두가 드러나고 있었으며 위기 유형에 따른 차이를 보이지 않았다. 내용 구조에서는 ‘사과 표현’에서 차이를 보였는데 ‘사고’와 ‘위반’에서는 정형화된 사과 표현을 주로 사용하였다면 ‘실수’에서는 다양한 사과 표현을 사용하였다. 사과 내용 설명에서도 ‘사고’와 ‘실수’가 ‘사과 내용 설명 > 사과 내용 추상적 언급 > 생략’의 순이었고, ‘위반’은 ‘사과 내용 추상적 언급 > 사과 내용 설명 > 생략’의 순으로 차이를 보였다. ‘문제 해결 방안’에서는 ‘사고’와 ‘위반’에 비해 ‘실수’에서 많이 생략되는 것으로 나타났다. ‘재발 방지 약속’의 경우도 ‘사고’와 ‘위반’이 비교적 구체적인 방안을 제시하는 데에 비해 ‘실수’는 자신의 노력을 약속하는 수준에서 그치고 있었다. This study aims to analyze the structure and linguistic expression in public apology texts by crisis type. The type of crisis was divided into ‘incident, mistake, and vionlation’ to investigate the structures of the participants and the contents, such as the description of contents of apology, the expression of apology, the solution to problems, and promise for recurrence prevention. As a result of the analysis, as the addressers in the structure of participants, most were institution names and institution representatives’ names for ‘incident’ and ‘violation’ and individuals’ names for ‘mistake.’ As the addressees, even if the victims were individuals, both individuals and groups appeared in written apologies, and there were no differences according to the type of crisis. In the structure of contents, there were differences in ‘the expression of apology,’ and in ‘incident’ and ‘violation,’ mostly, standardized expressions of apology were used, while in ‘mistake,’ various expressions of apology were used. In addition, there were differences as follows: The descriptions of contents of apology were in the following order: ‘Description of contents of apology > Abstract mentioning of contents of apology > Omission’ in ‘incident’ and ‘mistake’ while descriptions of contents of apology were in the following order: ‘Abstract mentioning of contents of apology > Description of contents of apology > Omission’ in ‘violation.’ As for ‘the solution to problems,’ it was omitted more in ‘mistake’ than in ‘incident’ and ‘violation.’ As for ‘the promise of recurrence prevention,’ relatively concrete solutions were presented in ‘incident’ and ‘violation’ while one’s efforts were promised in ‘mistake.’

This paper is Experimental Study on Reduction of Oil Carryover in Diesel Breather system. The Influence of design factor is demonstrated and the understanding of correlation between oil carryover and blow-by. When an engine is running, blow-by gases flow through the unavoidable clearance gaps between the pistons and the cylinder wall into the crankcase. If The Blow-by isn't vented, this case many bad effects such as LOC, corrosion by that and crank case explosion by rising pressure. Current emissions legislation demands that blow by gases are returned to the air intake system. But Oil carryover into blow by gases is pollution of Intake system. So Oil carryover depend on the quantity of Blow by. It is a following experiment to reduce oil carryover method, 1. Oil carryover by Crank case pressure control in rated power, 2. Baffle plate tuning for reduction of oil carryover in Rated power, 3. Baffle plate and PCV system compounding Test, 4. Influence of oil carry over in Max. blow-by, and 5. General Durability Test.
