이 연구는 공간영상정보의 대표적인 포맷으로 GeoTIFF, SDTS, HDF, BIIF를 크게 두부분으로 나누어 비교·분석하였다. 첫 번째는 각 포맷의 명세를 살펴보고 4가지 기준-확장성, 호환성, 범용성, 장기적인 안정성-에 기초하여 비교하였다. 두 번째는 실제적인 활용현황 및 호환성 평가로써 현재 많이 사용되는 상용 소프트웨어 5가지를 이용하여 각 포맷의 입출력 가능성과 서로간의 호환성을 조사하였다. 그 결과 4가지 포맷 중 현재로서는 GeoTIFF가 공간영상정보를 다루는데 있어 비교우위에 있음을 알 수 있었다. 그러나 앞으로 공간영상정보가 다양해지고 대용량화해짐에 따라 수많은 포맷이 개발되고 갱신될 것이므로 표준으로 하나의 포맷만을 계속 고집해서는 안 된다고 보여진다. 지속적인 연구를 통해 적절한 표준포맷을 제시함이 바람직하며, 또한 지속적인 정책지원이 따라야 할 것이다. This study has analyzed GeoTIFF, SDTS, HDF, and BIIF as the representative formats of spatial imagery information with two parts. First is to compare 4 formats with each other based on 4 comparison criteria (extensibility, interchangeability, current widespread use, long-term stability) by analyzing specification of each format. Second is to estimate current use and interchangeability of 4 formats between 5 commercial softwares used commonly. The result shows that GeoTIFF is currently better than three other formats. However, the more various spatial imagery information are and the larger capacity they have, the more formats are developed and updated, which means that only one format should not be considered as a standard format continuously. It is better to provide a standard format proper to the time through continuous research and sustainable policy support should be followed.

Purpose This study analyzed the outcomes of patients with resected extrahepatic bile duct cancer (EHBDC) in order to clarify the role of adjuvant treatments in these patients. Materials and Methods A total of 336 patients with EHBDC who underwent curative resection between 2001 and 2010 were analyzed retrospectively. The treatment types were as follows: surgery alone (n=168), surgery with chemotherapy (CTx, n=90), surgery with radiotherapy (RT) alone (n=29), and surgery with chemoradiotherapy (CRT, n=49). Results The median follow-up period was 63 months. The 5-year rates of locoregional failure-free survival (LRFFS), distant metastasis-free survival (DMFS), progression-free survival (PFS), and overall survival (OS) for all patients were 56.5%, 59.7%, 36.6%, and 42.0%, respectively. In multivariate analysis, surgery with RT and CRT was a significant prognostic factor for LRFFS, and surgery with CTx was a significant prognostic factor for DMFS, and surgery with CTx, RT, and CRT was a significant prognostic factor for PFS (p < 0.05). Surgery with CTx and CRT showed association with superior OS (p < 0.05), and surgery with RT had marginal significance (p=0.078). In multivariate analysis of the R1 resection patients, surgery with CRT showed significant association with OS (p < 0.05). Conclusion Adjuvant RT and CTx may be helpful in improving clinical outcomes of patients with resected EHBDC who have a high risk of disease recurrence, particularly R1 resection patients. Conduct of additional prospective, larger-scale studies will be required in order to confirm the benefit of adjuvant RT and CTx in these patients.

This study deals with the thickness irregularity of the sliver delivered from a drawing process based on a theoretical model. The thickness variation was expressed as CV(%) of the linear density of the drawn sliver in a steady state. Under the given simulation conditions the simulation results illustrate that the sliver linear density shows two types of behavior: a constant linear density and a periodically changing linear density with traveling peaks. For uniform staple-length slivers the linear density has multi-modal fluctuations, whereas the slivers with a distributed staple length show no fluctuation in the linear density at low sliver viscosity. The irregularity of uniform staple-length slivers is higher than that of the staple length distributed one. As the sliver viscosity increases, the irregularity of the drawn slivers increases.

Frictional bundling of fibers is accompanied by twists that compel the bundle cohesion force to generate bundle strength. Twists generated by friction occur in two forms; one by fiber arrangement on the bundle layer and the other by torque due to the thickness distribution of the bundle on the friction surface. This study investigates the twists of a friction bundle that occur on the friction surface, and theoretical models of twists are applied to develop total twist and the twist characteristics by simulation. Results showed that the fiber arrangement twists are directionally opposite to the torque twists; fiber arrangement twists occur as S-twists and torque twists as Z-twists. In the steady state the bundle exiting the friction zone had S-twists finally and the twists per length was uniform along the bundle radius. The steady state twists of the bundle at the exit of the friction zone were determined by two model constants and a process variable. The two model constants were composed of model parameters such as slippage ratio, minimum thickness of the fleece for bundling, the density ratio of the bundle to the input fleece, and also of process variables such as friction ratio, the speed ratio of the fleece feeding to bundle takeup, and the thickness of the input fleece. The process variable acting directly on the bundle twist was the fleece feeding width. Thus, the twist angle of the bundle in the friction zone varied with the radial position inside the bundle. The twist angle was the lowest in the vicinity of the bundle axis. As the fiber layer approaches the bundle surface, the twist angle increases.

This study reports on the output linear density that was attained by simulation for various levels of draft roller gauge and draft ratio, based on the dynamic model with approximated sinusoidal velocity variance model to specific fiber length distributions to test the model feasibility, while a random variation for the input bundle linear density was provided. Results from model simulation showed that a process resonance could take place, when the draft roller gauge or draft ratio reached the critical values, because there were fundamental frequencies which spread in the irregularity of the bundle linear density, giving rise to some resonance. Thus, the irregularity of the output linear density began increasing steeply. From the view point of the output linear density as a whole, the irregularity decreased, as the draft roller gauge increased. A process resonance occurred in the range of draft roller gauge between 1.25 and 1.5 multitudes of the (maximal) fiber length. Length distribution led to a lower fundamental frequency (longer fundamental wavelength) than the uniform fiber length. High draft ratio yielded high irregularity in the output bundle. Especially, the process resonance occurred between the draft ratio 20 and 30. In the draft ratio range higher than 30, the output included wide-ranged regularly oscillatory components of irregularity that corresponded to the integer-multiple of the fundamental frequency, which shifted to a higher value, when the fiber length was distributed. In addition, the approximated sinusoidal velocity variance model turned out to be adequate to estimate the irregularity of the bundle linear density with both the uniform and the quadratic fiber length distribution.

유사강간죄에 관한 재검토― 입법방식의 문제점을 중심으로 ―

Since 2010, the Korean Penal Code has been revised for three times including 2010, 2012 and 2013. Especially, the Korean Penal Code of 2012 revised and amended several elements of the Crimes of Rape and other Sex Offenses. The victim of Rape was changed from any Female to any Person. The Korean Penal Code of 2012 also adopted the Crime of Deviate Sexual Intercourse. The Crime of Deviate Sexual Intercourse refers to sexual conduct between the sex organs of one person and the mouth or anus of another. It also includes penetration of the genitals or anus of another person with a foreign object or the part of body (other than sex organs) of one person. Therefore, the Crimes of Rape and other Sex Offenses now have 3 categories: (1) Rape, (2) Deviate Sexual Intercourse, and (3) Forcible Sexual Contact. Even though Deviate Sexual Intercourse is more precise than that of German and others’ Penal Code, the Crime of Deviate Sexual Intercourse has several problems of legislation. First, the Crime was also adopted by other codes. Second, it is not reasonable to differentiate the victim of Rape from that of Deviate Sexual Intercourse because the benefit and protection of the code concerning the Crimes of Rape and other Sex Offenses is on the Rights to Self-Determination. 2012년 형법일부개정으로 유사강간죄가 신설되었다. 본 연구는 신설된 유사강간죄가 갖는 지위와 의미, 구성요건요소에 대한 기본적 파악을 하고, 외국의 입법례와의 비교를 통하여 본 죄의 신설에 있어서 문제점은 없는지, 있다면 향후 어떠한 개선이 필요한지를 검토한다. 이를 위하여 특히 입법방식의 문제점에 집중하도록 한다. 열거주의적 방식으로 유사강간죄의 행위 태양을 규정한 개정형법은 행위 태양의 불법성 정도에 따라 강간죄-유사강간죄-강제추행죄를 분류하고, 각각 별개의 법정형을 규정하고 있다. 즉, 열거주의적 규정방식과 차별적 법정형을 채택하고 있는 것이다. 이에 따른다면 성기 간 삽입을 요건으로 하는 강간죄가 가장 중한 불법성을 갖는다. 그러나 강간죄나 유사강간죄는 모두 피해자의 성적 자기결정권을 침해한다는 공통점을 갖고 있다. 또한 성기 간 삽입행위나 성기에 대한 그 밖의 신체 혹은 도구의 삽입은 모두 성적 자기결정권을 침해함에 있어 불법의 경중을 구별하기 힘들다. 여기에 더하여 형법전과 형사특별법이 동일한 유사강간죄에 대한 규정을 두고 있는 점 역시 중복적 입법으로 그 필요성에 의문이 든다. 따라서 본 연구는 이를 바탕으로 적어도 유사강간죄에 대한 형사특별법에 산재하는 복수의 규정들을 형법전에 통일적으로 규정해야 할 필요성을 제기한다. 더 나아가 유사강간행위를 기존의 강간행위와 함께 같은 법정형으로 규율할 필요성을 제기한다.
