Recently, FlexRay was developed to replace controller area network (CAN) protocol in chassis networking systems, to remedy the shortage of transmission capacity and unsatisfactory real-time transmission delay of conventional CAN. FlexRay network systems require correct synchronization and complex scheduling parameters. However, because platform configuration register (PCR) setting and message scheduling is complex and bothersome task, FlexRay is more difficult to implement in applications than CAN protocol. To assist a network designer for implementing FlexRay cluster, this paper presents an analysis of FlexRay platform configuration register and automatic generation program of PCR. To demonstrate the feasibility of the automatic generation program, we evaluated its performance using experimental testbed.

『孟子』 〈告子〉편의 構成方式과 主題에 관한 硏究

양재성(Yang Jae sung) 대동한문학회 2016 大東漢文學 Vol.48 No.-

본 논문은 孟子 〈告子〉편의 구성과 주제에 대하여 밝힌 것이다. 기존의 孟子 사상을 논하는 연구물들은 〈告子〉편의 텍스트를 많이 활용하고 있다. 그 내용은 대부분 ‘性’에 대한 철학적 담론이 주가 되고 있으며, 〈告子〉편 전체가 마치 전체가 ‘性善說’을 논한 篇이라는 인식이 자리 잡고있다. 그러나 이러한 연구들은 〈告子〉 章句 上의 일부 텍스트를 위주로 논의되었고, 上, 下를 총체적으로 다루는 연구로 나아가지 못하였다. 따라서 본 논문은 〈告子〉편 전체를 단락별로 나누어 분석해보고자 한다. 본고는 〈告子〉편의 구성을 모두 10개의 단락으로 분절하였다. 단락 분석의 방법은 論語 의 선행연구 방법을 채택하였고, 맥락에 맞게 내용별로 하나 이상의 장을 주제별로 묶어서 하나의 단락으로 본다. 첫 번째 단락은 1~6장으로 ‘본성은 선하며 仁義가 내재되어 있다.’는 것을 밝혔다. 두 번째 단락은 7~10장으로 ‘외부 환경에 따라 不善해진 왕과 신하들이 본성의 선함을 회복해 仁義의 정치에 힘써야한다.’는 것을 밝혔다. 세 번째 단락은 11~15장으로 ‘위정자의 본성인 仁義를 비유를 통해 제시하였다.’는 것을 밝혔다. 네 번째 단락은 16~18장으로 ‘仁義를 닦는 天爵에 힘써야 한다.’는 것을 밝혔다. 다섯 번째 단락은 19~20장으로 ‘성인의 도인 仁義를 법도로 삼아야한다.’는 것을 밝혔다. 이상은 章句 上이며 이론제시 및 전반부에 해당한다. 여섯 번째 단락은 21~24장으로 ‘仁義 政治의 실천덕목인 ‘禮’와 ‘孝’가 제시되었다.’는 것을 밝혔다. 일곱 번째 단락은 25~26장으로 ‘앞 단락의 구체적 사례로 폐백과 실천 방식’에 대하여 밝혔다. 여덟 번째 단락은 27~32장으로 ‘당대 군주와 위정자가 富國强兵이 아닌 仁義 政治를 구현해야한다.’는 것을 밝혔다. 아홉 번째 단락은 33~35장으로 ‘벼슬을 하기 위한 군자의 자질로 好善, 禮, 敬, 行’을 밝혔다. 열 번째 단락은 36장으로 ‘心志를 세우는 것이 仁義 政治의 실현방법이다.’는 것을 밝혔다. 이상은 章句 下이며 上에서 밝힌 이론적 제시를 통하여 이를 실현할 수 있는 실천적 방향으로 결론짓는 방식으로 나아가고 있다. 이로서 〈告子〉편의 주제는 단순히 본성이 선하다는 것을 밝히는 데에 그치지 않고, 선한 본성 곧 仁義의 자질을 회복하여 잘 지켜나가는 사람만이 군자로서 왕도정치를 구현할 수 있음을 밝혔다. This paper presents an investigation into the organization and topics of the Goja book of Mencius. Previous studies that discussed the ideas of Mencius made much use of texts from the Goja book, mostly dealing with philosophical discourses about “sex.” There is a perception that the whole content of Goja addressed “the theory that human nature is fundamentally good.” Those studies, however, focused their discussions on some texts from Janggu Sang in the Goja book, never proceeding to address the entire Sang and Ha. The present study thus set out to analyze the whole Goja book by section. The investigator divided Goja into ten sections by employing the method of section analysis for the Analects of Confucius in previous studies. One or more chapters were put in the same section based on context and content. Section 1 spans from Chapter 1 to Chapter 6, demonstrating that “human nature is fundamentally good and has humanity and justice in it.” Section 2 encompasses Chapters 7~10, stating that “the king and his subjects, that have been evil due to the external environment, should restore the goodness of their nature and devote themselves to the politics of humanity and justice.” Section 3 contains Chapters 11~15, arguing that “humanity and justice, part of a politician s nature, has been proposed through figure of speech.” Section 4 includes Chapters 16~18, maintaining that “they should work on their natural nobility of cultivating humanity and justice.” Section 5 includes Chapters 19 and 20, arguing that “they should take humanity and justice, the morality of saints, as their custom.” Those belong to Janggu Sang, proposing theories in the former half. Section 6 spans from Chapter 21 to Chapter 24, showing that “courtesy and filial duty, the practice of virtues of politics of humanity and justice, have been proposed.” Section 7 includes Chapters 25 and 26, discussing “Pyebaek and methods of practice as the specific cases of the previous section.” Section 8 includes Chapters 27~32, arguing that “the contemporary monarchs and politicians should carry out politics of humanity and justice instead of national prosperity and military power.” Section 9 contains Chapters 33~35, mentioning “Hoseon, courtesy, respect, and action as the qualities of a man of virtue to hold government positions.” The final Section 10 is Chapter 36, stating that “keeping one s will right is to practice the politics of humanity and justice.” Those belong to Janggu Ha, reaching a conclusion toward practicable directions to implement them by proposing the theories addressed in Sang. Those findings indicate that the topics of Goja go beyond the demonstration that human nature is fundamentally good and maintain that only those who restore and practice their good nature or the qualities of humanity and justice can carry out benevolent royal politics as men of virtue.

Orthotropic Plasticity 기법을 이용한 Aluminum Honeycomb 구조물의 수치해석 모델

양재성(Jae Sung Yang) 한국강구조학회 1994 韓國鋼構造學會誌 Vol.6 No.4

In recent days, honeycomb structure is being adopted in various fields of structural engineering due to its peculiar orthotropic strength. Especially, it shows high potential to be used as an energy absorbing media. Typically, aerospace industries and high speed train, i.e. TGV, have fully used the strength of honeycomb-type structure while minimizing the total structure weight. However, it is a challenging task to develop a numerical method for simulating honeycomb-type structures. In the present paper, a finite element method is used to develop a numerical model of a honeycomb structure by using orthotropic plasticity and Tsai-Wu yield function. This method is validated by comparing numerical results with test results generated from honeycomb structures impacting rigid objects and exhibits excellent correlations with the test results.

양재성 ( Jae Seong Yang ),오순복 ( Soon Bok Oh ),임성수 ( Sung Soo Lim ) 한국사회보장학회 2012 사회보장연구 Vol.28 No.3

본 연구에서는 2011년 상반기 신규 산재장해인 취업실태조사 자료를 이용하여 산재장해인의 요양종결 후 직업복귀 형태에 영향을 미치는 결정요인을 분석하였다. 직업복귀의 형태는 원직복귀, 재취업, 자영업으로 구분되며 분석결과를 통하여 직업복귀율 제고에 대한 정책적 시사점을 제공하는 데 목적이 있다. 분석대상은 경제활동 가능 연령인 15세에서 60세까지로 한정하였다. 분석결과 연령이 높을수록, 그리고 요양기간이 길수록 원직복귀 확률이 낮은 것으로 나타났다. 직업복귀에 대한 지역별 차이에 있어서는 부산, 경인지역 관내에서 원직복귀 확률이 높았던 반면, 광주와 대전지역 관내에서는 자영업에 종사할 확률이 높았다. 또한 사례관리대상자의 경우 원직복귀보다는 자영업이나 재취업 형태에 복귀 확률이 높게 제시되었다. 외국인 근로자의 경우 점포지원 등의 제도적 한계로 인하여 자영업으로 복귀할 확률은 낮았으며, 원직복귀보다는 재취업 경향이 뚜렷하였다. 따라서 산재장해인 직업복귀율 제고를 위해서는 재해발생 시점부터 사례관리서비스(내일찾기서비스) 제공으로 원직복귀와 자영업 및 재취업 가능자를 분류하여 집중치료제 등을 통한 요양관리, 의료기관과 연계한 개인별 맞춤형 직업복귀 계획수립과 관리가 필요할 것으로 본다. 또한 연령대별, 지역별, 장해정도, 사례관리대상자별 차등적 정책 접근으로 획일적 재활정책에서 벗어나 산재근로자의 사회복귀 및 직업복귀 촉진을 위한 방향 설정이 요구된다. This study analyzes the factors of return-to-work types & regional charactertics using survey data of new occupationally disabled workers in the first half of 2011. The return-to-work type is are three types, ``job retention``, ``re-employment``, ``Self-employed``, The aim of this study is to target differential vocational rehabilitation and to serve information for setting the policy direction on the basis of the analysis results, The empirical results shows that younger age, shorter treatment duration is quite practicable return to work and foreign is quite practicable reemployment. Case management for participants were presented rather higher the probability of self-employed or re-employment than job retention. We also find that job retention is higher In Busan, Incheon area than in Seoul area. The other hand, Self-employed is higher in Gwangju, Daejeon area. Therefore return to work of occupationally disabled workers policy is required to considering the characteristics, regional, age, case management.

딤플 뒤에 와류 발생기를 가지는 냉각 유로의 유동과 열전달 성능에 관한 수치적 연구

양재성(Jae Sung Yang),정명근(Myunggeun Jeong),박용갑(Yong Gap Park),하만영(Man Yeong Ha) 대한기계학회 2017 대한기계학회 춘추학술대회 Vol.2017 No.11

In the present numerical study, the detailed flow structure and heat transfer characteristics with the newly designed dimple cooling channel were investigated. The surface geometry was proposed in the present study, it was a general dimple structure combining with a vortex generator behind the dimple, which is called dimple with vortex generator. The main purpose of surface geometry was to enhance the flow mixing and heat transfer in the flow-recirculating region that was generated by a dimple cooling channel. Direct numerical simulations (DNS) were carried out with a Reynolds number of 2800 and Prandtl number of 0.71 in the cooling channel. There were four different cases: a general dimple case, dimple with vortex generator cases with three different tip angles. The overall pressure drop and heat tranfer for dimple with vortex generator cases were higher than the general dimple case.

『맹자(孟子)』 양혜왕편(梁惠王篇)의 구성(構成)과 서술방식(敍述方式)에 대한 연구(硏究)

양재성 ( Jae Sung Yang ),송병렬 ( Pyung Nyul Song ) 근역한문학회 2016 한문학논집(漢文學論集) Vol.43 No.-

This study examined the reasons behind the selection of Book of King Hui of Liang of Mencius as a Supyeon, as well as its organization and connection styles. Previous studies on Mencius were mostly restricted to the phrases and chapters with few researches on the overall flows of books, the combinations of phrases and chapters. The present study thus set out to understand the overall flows of Mencius based on Book of King Hui of Liang. The Analects of Confucius, on which Mencius based his ideologies, were compilations of edited words of Confucius, which is why the narration processes were not in the same point of view. It is thus not easy to figure out the ways the books and chapters were organized and composed and the inquires were made. Mencius, on the other hand, contains independent chapters organically connected to each other and thus has a much more typical style of narration than The Analects of Confucius. The organization of Book of Hui of Liang of Mencius mainly follows humanity and justice royal politics qualification of realization reality of royal politics Heaven’s will, encompassing the topic of humanity and justice and its politics, namely royal politics. The organization of Book of Hui of Liang demonstrates that Mencius is not the simple records of his conversations with feudal lords and kings in a sequential manner. The Book employs questioning and answering, quotation, and allegory as its major rhetorics to express its topic. Those rhetorics are concise but very persuasive, thus claiming the significance of huge effects in terms of topic delivery.

출퇴근재해제도의 도입 시나리오에 관한 연구 - 재정부담 설정을 중심으로 -

양재성 ( Jae Seong Yang ),오순복 ( Soon Bok Oh ),임성수 ( Sung Soo Lim ) 한국사회보장학회 2014 社會 保障 硏究 Vol.30 No.2

본 연구는 근로자의 출퇴근재해 도입 시 재정부담 주체 및 요율 설정 방안을 모색하고, 예상되는 요율 수준을 계측하여 제시하는데 목적이 있다. 재정부담 주체 및 요율설정방안은 이론적 배경 및 해외 주요국가 사례를 분석의 틀로 구성하였으며 요율수준은 선행연구의 고찰을 통해 제시하였다. 첫째, 출퇴근재해가 산재보험제도에 포함되거나 유사 제도로 도입될 경우, 업무의 연속성 관점에서 재정부담은 사업주가 될 가능성이 높다. 다 만, 출퇴근 범위는 사업주 지배관리 영역이 아니라는 점에서 재해에 대한 법률적 책임은 업무재해와 차별화되어야 한다는 점을 강조하였다. 별도의 제도로 도입될 경우에는 사업 주, 근로자, 정부 등 사회구성원의 분담 방안 검토가 가능하다. 둘째, 보험료율은 업무재 해 급여총액에 포함하여 사업종류별로 설정하되 개별요율에는 포함하지 않는 독일방식과 별도의 재해부담률을 구성 요소로 설정하여 추가하는 프랑스, 일본 방식의 도입 방안 등을 제시하였다. 셋째, 2013년 예상 소요비용을 중심으로 산재보험료율 산정방법에 따라 부담률을 산정한 결과, 출퇴근재해 도입 시 근로자 보수총액의 0.2~0.24% 수준의 요율이 추가될 것으로 예측되었다. 다만, 제도설계 및 구상권 행사 비중에 따라 변화 가능함을 제시하였다 This paper aims to find the methods of setting financial burden and premium rates by anticipating the level of premium rate, resulting from introducing commuting accident compensation. The methods of financial burden and premium rate are analyzed, based on several foreign cases, and the level of premium rate is measured by reviewing the previous researches. First, if commuting accident is included in the current WCI or is introduced as similar system, all financial burden is attributed to businessmen, considering the present system. However, the legal responsibility is different from the occupation disaster, since commuting is not under the area of employers` management. Besides, if commuting accident compensation is introduced as a separate system, the method of distributing burden among businessmen, labors, the government, etc can be considered. Second, the study suggests the two methods to set the premium rate. One is set with business type as in Germany by adding commuting accident benefits to work-related ones but not including them in the individual premium rate of a workplace. The other is used in France, Japan, and is that the commuting accident benefits are separated with work-related ones but are added to the workplace`s premium rate. Third, by calculating the premium rate based on the expected expenses in 2013, the commuting accident can increase 2~2.5‰ of the premuim rate on average. But this estimation can be changed by the system designing and the extent of exercising the right to indemnity.
