The morphology of plants and scanning electro-microscopical features of fruits were examined to evaluate the taxonomic entities of Korean Adonis L. in sensu lato (Ranunculaceae). The species of Korean Adonis were readily diagnosed by the branching pattern of stem, the number of flowers, the bifurcation of leaf main axis, the number of tepals, the flowering periods in relation to leaf sprouting, and the number of stomata and the texture of fruit surface. This study demonstrates that there are three species, A. amurensis, A. pseudoamurensis, and A. multiflora., found in Korea. However, A. ramosa, which has been often claimed to be distributed in Korea, is not present in Korea.

Saussurea pseudogracilis Kitam. is characterized by its slender leaves, small involucre and small number of involucral bracts compared to Saussurea gracilis Maxim. But some taxonomists insist that it is hard distinguih S. pseudogracilis from S. pseudogracilis. We tried to discern taxonomic identification of S. pseudogracilis by measuring and analyzing 45 qualitative characters and 42 quantitative characters on 165 specimen. S. pseudograilis was not distinguished from S. gracilis not only by qualitative characters but also by quantitative characters even on statistical analysis(PCA). Therefore, S. pseudogracilis is not independent taxonomic species and it is proper to consider S. pseudogracilis as a synonym of S. gracilis.

고체 추진제를 사용하는 추진 시스템을 개발하는데 가장 커다란 문제로 인식되고 있는 것은 추진제의 연소 특성을 이해하는 일이다. 그 중에서도 연소실의 압력 진동과 추진제 벽면으로 흡수되는 복사 열전달에 의한 연소율(burning rate)의 변화로 인하여 발생하는 연소 불안정에 대한 이해는 아직도 완전히 규명되지 않고 있다. 고체 추진제의 연소 불안정에 대한 이론적 해석은 준-정상 1차원 해석(Quasi-Steady Homogeneous One-Dimension) 방법에 의하여 단순화된 지배방정식을 해석하는 것이 일반적으로 잘 알려져 있는 방법이다. 이 가정은 고체 추진제가 연수되는 영역을 두께가 매우 얇은 영역의 표면반응영역(surface reaction layer)과 화학반응이 없는 응축상태영역(condensed phase zone) 그리고 기체상태의 연료와 화염이 존재하는 기체상태영역(gas phase zone) 등의 3영역으로 구분하며, 기체상태영역에서 발생하는 교란에 대한 응축상태영역의 반응시간 크기(response time scale)가 매우 크기 때문에 응축상태영역의 반응은 준 정상적으로 일어난다고 가정하는 것이다.그러나, 연소실의 온도가 $3000^{\circ}K$ 정도의 높은 온도이어서 복사 열전달에 의한 고체 추진제의 가열이 중요한 열전달 방법으로 작용하게 되므로 이를 무시한 이론적 해석은 물리적인 중요성이 약하여질 수밖에 없다. 본 연구에서는 기체영역으로부터 전달되는 복사 열전달은 투명(transparent)한 표면반응영역을 통과하여 응축상태영역에서 모두 흡수되며 추진제 표면에서의 복사열방출(emission)을 고려하였다. 또한 연소불안정 현상을 해석하기 위하여 표면반응영역에서의 경계조건은 선형교란량으로 대치하는 Zn(Zeldovich-Novozhilov) 방법을 사용하였다. 이 방법은 기체상태영역에 대한 구체적인 해석없이도 연소불안정 현상을 해석할 수 있는 장점이 잇다. 즉 응축상태영역에서의 연소율과 표면온도는 각각 기체영역으로부터 전달되는 온도구배와 연소압력, 그리고 복사 열전달의 함수관계이므로 선형교란에 의한 추진제표면에서의 교란경계조건을 얻을 수 잇으며, 응축영역의 교란지배방정식과 함께 사용하여 압력교란과 복사 열전달의 교란에 대한 연소율의 교란 증감 여부를 판단하여 연소 불안정 현상을 해석할 수 있다.

Recently, in the cyberspace, the posts that have only insults and abuses without the fact are getting spread rapidly as a trend, it makes the damage to people also, and the social concerns have been raised about its phenomenon. Meanwhile, because of the insulting actions that performed in cyberspace, the results of infringement of personal rights conditions getting difficult to repair. Also, it is difficult to find who the person who acts as a perpetrator is. So, it is hard to report a crime or sued for damages, also, it is really difficult to deal with a criminal contempt. Also, cause of a lot of deficient areas, the Cyber Insult Crime act is need and strengthened penalties or Mitigation about the crime subject to victim's complaint are need. However, give the criminal penalties to criminal is sufficient. So, to construct a new special criminal law, it is not advisable. Thus, governed by the Criminal Code Section 311 is preferably.

This study presents limitations of the old family supported system for the elderly being surfaced in the face of the changing life style of the people in today's industrialized, urban Korean society. The qualitative data used for this study are collected from the focus group discussions(FGD). The FGD data numbered a total of 43 participants who were divided into 8 different groups, each consisting of 5-6 respondents sorted out by sex and age as well as by their current cohabitation with their parents or having such experience in the past. The study paid special attention focusing on the values and the expectations regarding the elderly support and the family relationship. A critical reexamination of the old family support system for the elderly at this particular juncture is also a step forward necessary for the eventual formulation of policy measures by the state and the society to produce a new viable support system for the elderly in the future.

The plant names Hwangjeong and Wiyu were written in Chinese characters in Hyang-yak-jib-seong-bang during the early Chosen dynasty. However, soon after, Hwangjeong and Wiyu were written in Korean characters as Jukdae and Dung-gul-re, respectively. However, since under the Japanese imperialist period in Korea, the taxonomic identities of these two Korean names have been incorrectly understood, with scientific names incorrectly assigned as well to these two names thus far. The results of the present study prove that Hwangjeong is Polygonatum sibiricum and that its Korean name should be Jukdae, its initial Korean name, and not Cheung-cheung-gal-go-ri-dung-gul-re, as used recently. Meanwhile, during the Japanese imperialist period, Wiyu was termed P. officinale or P. japonicum with the Korean name of Dung-gul-re. However, the correct scientific names were shown to be synonyms of P. odoratum.

This study aims to propose task areas which have to be discussed for reforming of the Public Records and Archives Act in Korea. For drawing the task areas, it analysed the pending issues mainly presented in the policy forums co-hosted by Korean Society of Archival Studies and Korean Association of Records Managers and Archivists, and examined researches providing tasks of revising of the law or rebuilding public records policies related in digital records management. The 4 task areas were identified, which were the exhaustive documentation of the public agencies' activities, the reexamination of the appraisal systems for public records and archives, the transition into the 2nd generation-digital records management, and the redefinition of roles and responsibilities of the records/archival institutions. Then it placed the issues into the 4 areas, and proposed some suggestions for further discussions in each tasks. Reminding that the task areas proposed in this study are not comprehensive, further suggestions and arguments will be expected for reforming the Public Records and Archives Act.

Through excavation on Anapji Pond from March 1975 to December 1976, it was discovered that the whole area around Anapji Pond had been called East Palace (東宮) since 7th century and that the original name of East Palace was Wolji Palace (月池宮) through excavation in 1980. The excavation proved that the original name of Anapji Pond was 'Wolji.' In academic world, there are many scholars who recognize this place as the Crown Prince's palace for being called East Palace. East Palace (which is read Dong Palace with pronunciation in Korean alphabet) actually is another name for Crown Prince's palace. This place, however, cannot have served as Crown Prince's palace as 'independent, exclusive space.' After 7th century, there were detached palaces in Silla including East Palace South Palace North Palace and Yang Palace other than Jeong Palace in Wolseong. East Palace is a palace located in the east. The palace's name is based on bearing and it does not indicate Crown Prince's palace. This article proves that East Palace cannot have been Crown Prince's palace through newly analyzing materials related to Wolji Palace.

IT-related fields are very diverse. As of 2018, the IT revolution from the Fourth Industrial Revolution not only brought out the new fields that were different from the previous ones, but it also made a reexamination of various fields that had already been an issue in the past. Companies and public institutions have a great interest in understanding IT trends in this situation. Therefore, in this paper, IT trends are identified through the analyzation of keywords provided by domestic papers. Moreover, unlike previous industry trend analysis or economic analysis, this paper focuses on analyzing the keyword provided by the doctoral thesis or master's thesis about direct IT-related research, and grasps the more basic and direct IT trend. This analysis predicts and presents the vision based on the data of the analysis from the academic papers that researched in IT technology for IT related students or IT related educators.

Occupational therapist is required for patient-centered approaches to actively seek the perspectives of patients and their families in clinical settings. The purpose of this study was to investigate the current trends and to suggest future-oriented view of examination and assessment used by neurological occupational therapist in clinical settings. Sixty-six occupational therapists who work in persons with neurological disorders participated in this study. The survey was measured from Seoul and GyeongGi by means of E-mail about commonly used assessment tools and selecting considerations. The participants were 66 neurological occupational therapists. The number of patients by one day was from 10 to 14 persons, and the length of time for initial evaluation was 20-40 minutes per one patient, and reexamination periods was every 1 month or as functional changes were detected. The using tool was not limited only neurological tools, and choice consideration was the reliability and validity of clinical measures. The most frequently used tools for adults were: JHFT for motor function in upper extremity, MMSE-K for cognitive perceptual assessment, MBI for daily activity assessment, and COPM for occupational performance. The most frequently used tools for child were: MVPT for cognitive perceptual assessment and Wee-FIM for daily activity assessment. The results of this study suggest that it is necessary to integrate and associate patient-report, care-giver report, and results of performance-based assessment for estimating plan of care more quality.
