There is a vessel which shall not impede the passage of any other vessel in the COLREGS 1972. But the issue was raised that the words of "not to impede" were vague. Therefore, IMO adopted new paragraph (f) to be added to Rule 8 that a vessel which is required not to impede the passage of another vessel is not relieved of this obligation if approaching the vessel so as to involve risk of collision. It means that the ship which is obliged not to impede should contributes to avoid collision and to the safe passage of the other vessel. Also it results that the application of Collision Rules should be changed. But until now, it seems that the mariners are not familiar with this subject. This paper, therefore, aims to define the meaning of "not to impede" and clarify it's legal concept so as to adequate application of the Collision Rules for the collision avoidance at sea.on avoidance at sea.

해상교통법에서는 다른 선박을 피하여야 하는 의무를 가지는 서로 다른 두가지 그룹의 선박이 있다. 하나는 다른 선박의 진로를 피하여야 할 선박이고, 다른 하나는 통항을 방해하지 아니할 선박이다. 통항불방해의 무선박의 개념은 1972년 국제해상충돌방지규칙의 1987년 개정에서 제8조 (f)항을 채택함으로써 분명하여졌다. 그러나, 한국정부는 이러한 규정을 한국의 국내법에 현재까지 수용하지 아니하였다. 그리하여 통항불방해의무선박의 정의와 적용에 대하여는 학계에서조차도 크게 논의되지 않고 있다. 최근 대법원은 통항불방해의무선박이 관련된 충돌사건에 대한 판결을 내렸다. 필자는 외국 학자들의 논문과 국제해사기구의 문서를 참조하면서, 통항불방해의무선박에 대한 자신의 견해를 밝히면서 대법원의 판결을 비판하고 있다.

The purpose of this study is to investigate the reasons of Object Attachment Occurrence in infant and the meanings of it in his early development. For this purpose, the following hypotheses were supposed. 1. Infant's object Attachment will be a substitutional for mother attachment when he has opportunities to his mother during his first years. 2. Infant's Object Attachment will not impede the infant's normal development. In order to test this hypotheses 28 mothers whose infants show or have shown this phenomenon and 28 mothers whose infants show or have shown this phenomenon and 28 mothers whose infants do not show this one were interviewed about their child rearing practice and attitude. They were selected by the random sampling method from 310 household wives living at a delux Apt. in Seoul. The results obtained in this study are as follow ; 1. The less opportunities infant has for 1) his mother's breast feeding 2) having physical contact with his mother 3) spending time with his mother 4) receiving prompt response from his mother to his crying, the more he is apt to show this phenomenon. And infant whose first main attachment figure is not his mother also shows the same apt. 2. There was no difference between two groups in intelligence and personality. So it can be concluded that infant's Object Attachment is a substitutional phenomenon for mother attachment in the mother during his first years, and it does not impede infant's normal development.

본 연구의 목적은 질적 메타요약 방법론을 활용하여 국내 게이, 레즈비언, 바이섹슈얼 성소수자의 성정체성 형성 과정에 영향을 미치는 요인들을 살펴본 질적 연구들을 체계적으로 종합함으로써 이질적인 질적 연구 결과를 통합적으로 이해하는 것이다. 국내 질적 연구들을 통해 보고된 성소수자의 성정체성 형성에 영향을 미치는 요인들을 종합하여 이러한 요인들의 보편성과 특수성을 파악하는 것은 그들의 내적 경험을 이해하고, 심리적 적응을 돕는데 중요하다. 본 연구는 질적 메타요약을 통해 국내 질적 연구들이 제시한 게이, 레즈비언, 바이섹슈얼 성소수자들의 성정체성 수용과 통합, 더 나아가 긍정적 정체성 형성에 관여하는 심리적 요인과 사회적 요인을 확인하고 체계적으로 요약하고자 하였다. 먼저 학술DB 검색을 통하여 국내에서 2021년까지 발표된 총 9편의 관련 연구물을 확보하였다. 9편의 연구물의 질은 Critical Appraisal Screening Programme을 통해 평가되었다. 분석 결과, 총 179개의 진술문이 추출되었고 관련 진술문들을 축약시킨 결과 34개의 축약진술문이 산출되었다. 34개의 축약 진술문은 성정체성 발달을 저해하는 요인과 촉진하는 요인, 심리적 요인과 사회적 요인의 두 가지 축을 기준으로 크게 성정체성 발달을 촉진하는 심리적 요인과 사회적 요인, 성정체성 발달을 저해하는 심리적 요인과 사회적 요인의 네 영역으로 나눌 수 있었다 논의에서는 영역별 주요 요인을 설명하였으며, 본 연구 결과의 함의와 제한점을 제시하였다.

As the business environment is rapidly changing with globalization and complexity of information flows, the uncertainty is also very increased for project environment. Although many studies have been conducted to find out the critical factors for project success, there still exist different views to define project success. Furthermore, implementing success formula for one project does not necessarily guarantee a success for another project since there are other elements that impede the success of project. In this regards, it is imperative to examine what are the barriers to project success. This study aims to examine the barriers that impede the success of project. Past literature was thoroughly reviewed to collect and develop a preliminary list of elements that affected project performance negatively. Experts were interviewed to refine the list and the final list of the measurement items were developed. A survey questionnaire was developed with the final list of measurement items, and a survey was conducted on the practitioners with project experience. After the survey, an exploratory factor analysis was conducted on the final list to extract the component dimensions which in turn formed the group of project barriers. The exploratory factor analysis provided ten factors, which are difficulty of process management, failure of project feasibility analysis, cost overruns and lack of cost benefits, unclarity project plan, strategic consistency error, stakeholder conflict, inaccuracy of requirement definition, disturbance of communication, technical environment change, negative attitude of top management.

High frequency induction welding is widely employed for longitudinal seam welding of small scale tubes and pipes because of its relatively high processing speed and efficiency. This research is aimed at understanding the variables that affect the quality of the high frequency induction welding. The welding variables include the welding frequency, weld speed, V-angle and tube thickness. Temperature distribution of the tube is calculated through three dimensional coupled electromagnetic and thermal FE analysis. The skin and proximity effects are considered in the electromagnetic analysis. The influence of the impeder is also analyzed. The effects of the operating welding variables on the temperature distribution are investigated quantitatively by exhibiting the heat affected zone (HAZ). The results explain the mechanism of significant enhancement of welding efficiency when the impeder is used. The proper welding conditions without the overheated edge are obtained through FE analysis.

Due to high corrosion resistance, Zinc has been widely used in the automobile, shipping or construction industries as a galvanizing material. Zinc is popular as a coating element, but its low mechanical strength impede the expansion of applications as a load-bearing structure. The mechanical strength of Zinc can be increased through zinc based alloy process, but the ductility is significantly reduced. In this study, the mechanical strength and ductility of Zinc-Magnesium alloys with respect to heat treatment hold time was investigated. In order to enhance the mechanical strength of Zinc, a Zinc-Magnesium alloy was fabricated by a melting process. The heat treatment process was performed to improve the ductility of Zinc-Magnesium alloy. The microstructure of the heat-treated alloy specimen was analyzed using SEM. The hardness and compressive strength of the specimen were measured by a micro-hardness tester and a nano-indenter, respectively.

Direct current (DC) applied to cotyledons during a 16 h inductive dark period inhibited the flowering in the short-day plant, Pharbitis nil Choisy cv. Violet. The inhibitory effect of DC was more profound when the current flowed from roots to cotyledons, showing its polarity-dependent action. The second half on the inductive dark period was more sensitive to DC stimulus. The flowering was significantly depressed only when DC stimuli were applied to the translocation path of the floral stimulus from the induced cotyledon to the apex, suggesting that the transport of floral stimulus was damaged by the DC treatment. The vegetative apex culture bioassay system showed that a significant level of the floral stimulus activity existed in the phloem exudate from the cotyledons which would fail to form their own floral buds. These results strongly support the hypothesis that DC partially impede, at least temporarily, the transmission path of the floral stimulus from florally-induced cotyledon to the apex, rather than depressing in situ synthesis of the floral stimulus.

A ventriculo-peritoneal shunt is a standard surgical management for hydrocephalus, but complications may impede the management of this disease. Obstruction of the catheter is one of the most common complications and manifests clinically in various ways. Intraparenchymal cyst development after shunt malfunction has been reported by several authors, but the underlying mechanism and optimal treatment methods are debatable. The authors report a case of intraparenchymal cyst formation around a proximal catheter in a premature infant after a ventriculo-peritoneal shunt and discuss its pathogenesis and management.
