Background/Aims: Rectal carcinoid tumors can be resected with endoscopy, and it is important to assess their prognostic factors. We evaluated the potential of Ki-67 expression as a prognostic factor in rectal carcinoid tumors. Methods: We retrospectively reviewed the medical records of 37 patients with rectal carcinoid tumors who got endoscopic resection from January 2001 to January 2011 at Inje University Seoul Paik Hospital. We analyzed their endoscopic and histologic findings, Ki-67 expression, clinical outcome, and prognosis. Results: The mean age (±SD) of the patients was 56.3±10.7 years, and the male : female ratio was 3.6:1. The mean tumor size was 0.5±0.4 cm, 33 patients showed grade 1 tumors (89.2%) and the average Ki-67 expression was 0.7±1.2%. Thirty five patients underwent endoscopic mucosal resection, and two required endoscopic submucosal dissection. Eight patients had positive margins after resection, but no cases of lymphovascular invasion were identified. The median follow-up duration was 21.4±25.4 months, and no recurrences were observed. Conclusions: In low grade rectal carcinoid tumors which are lack of central depression on colonoscopy, the expression of a molecular marker of malignant potential, Ki-67, was low. Therefore, endoscopic resection seemed to be a safe and effective treatment for these tumors.

Primer 155(GCTGGCGCTG) was the most useful primer with distinctive polymorphic DNA pattern to distinguish between KI races and KJ races. Primer 173(CAGGCGGCGT) showed polymorphic DNA pattern to distinguish isolates of KI-100 race. The specific DNA fragment of 0.6Kb, generated from 88-62 of KJ-201 race by RAPD with primer 412)TGCGCCGCTG), was promising as a molecular marker to identify the isolate.

본 연구는 기존의 순위만 고려하는 집중도를 보완하여 기대빈도를 이용한 새로운 상대집중지수 NOHI(Nam-Oh-Hong Index)를 제안하고, 이를 지역별 직업별 종사자 수에 적용함으로써 지역별 특화 직종 분포에 활용하는데 있다. 지역 간 특화정도를 보여주기 위해 개발된 입지계수(LQ)의 경우, 해당산업의 지역 내 비중을 상대적으로 고려하지 못함에 따라 지역 내 특성화를 반영하지 못하는 한계를 내포하고 있다. 본 연구에서 제안하는 NOHI는 이러한 단점을 보완하여 산업 및 직종의 지역간 지역내 특화도를 동시에 나타낼 수 있다. 본 연구에서 제안하는 NOHI를 활용하여 분석한 결과 서울은 경영 회계 사무관련직의 특화도가 높은 것으로 나타났으며, 부산은 기계 재료관련직의 특화도가 높은 것으로 나타났다. The purpose of this study is to introduce a relative specialization index, the Nam-Oh-Hong Index(NOHI) and to investigate regional distribution of occupational specialization using the newly developed index. Compared with Location Quotient(LQ), the advantages of the index is that the NOHI enables comparison between inter-regional and intra-regional concentration of employment possible at the same time. The results of the specialization analyses show that Seoul is specialized in management, book-keeping and office related occupations, whereas Busan in machine and material related occupations.

This study is designed to grasp the elements and situations of stage fright in order to propose a part of ways to cope with it. We make 511 top-class high school players, male and female, in the central districts (Seoul, Inchon, Kyungki, Chungbuk, and Kangweon Province) on object of questionnaire, and get the following results. Through players generally have all-round characters they show weakness in the superiority and emotional stability while showing strength in the sonformity. This fact comes to be related to the elements which cause stage fright. Physiological changes also have many effects on the symptom of stage fright. Especially, stage fright increases when players show sensitive reaction to the self-consciousness of final consequence which comes from the tension or uneasiness of sympathetic nerve, Thus, it turns out that players make use of reducing psychological burden by physical exercise or adjusting the level of demanded result in order to release the stage fright.

A gas sensor of PdCl₂ materials has been prepared by ceramic technology. The soaking temperature and time was 600-900℃ and 1 hour respectively. The characteristics of gas concentration versus electrical conductivity as a parameter of soaking temperature were measured. The semiconductor gas sensors prepared have shown the high sensitivity to the combustible gas e.g. propane gas. So they could be used as elements of propane gas sensing equipments.

In this study, structural analysis of worn tire to current forces is performed to investigate its behavior charateristics. For the behavior analysis of worn tire, finite element model representing orthotropic material of tire, SAP, and ANSYS are applied. In case of finite element model used in this study, the material and geometric nonlinearities are not considered. And also, the analysis of large deformation and the contact element of three dimensional structure is not given in SAP. Two dimensional link element may be used in stead of contact element. Mean while, ANSYS provides three dimensional contact elements in order to do contact analysis and give the supplementary results which SAP doesn't cover.
해고제한의 법리로서 불법행위이론 : 미국의 공공정책 불법행위 이론을 중심으로 mainly on the public policy torts theories U.S.A

Courts in most states recognize a private right of action for dismissals that jeopardize specific public policy interests of the state. This category of tort liability is called the public policy tort. The public policy tort, is a specific application of the prima facie tort. The public policy tort permits recovery by a dismissed employee only when the dismissal violates a clear public policy of the state. The prima facie tort allows recovery if the employer dismissed the employee with malice and without justification. Malice is a legal term of art that means little more than the mental state that motivates harmful conduct in the absence of justification. Intentional tort principles applicable to these categories permit a plaintiff to recover only by showing that a legally protected right of the plaintiff was harmed by an act of the defendant and that the defendant lacked justification for his act. The public policy tort theory expands the range of circumstances in which an employee may recover without having to establish the employer's conduct or state of mind sufficiently to satisfy traditional tort categories such as intentional interference with contractual relations, intentional infliction of emotional distress, fraudulent misrepresentation, defamation, or invasion of privacy. None of these traditional theories permitted the employee to recover for the dismissal itself. The newer public plicy tort theory permits a dismissed employee to recover for the dismissal itself. Public policy tort cases require courts to balance the interests of the employee, employer, and society under formula presented in § 870 of the Restatement(Second) of Torts.

??? gas Sensors were fabricated by firing the mixture of SnO₂and Th(NO₃)₄, Their electrical properties sensitivity characteristics to gases have been investigated. The mixture of 95 wt.% SnO₂and 5 wt.% Th(NO₃)₄fired at 600℃ for 1 hour showed the highest sensitivity to ??? gas. It is suggested that they could be used as the elements of ??? gas detecting apparatus.
