Objectives: This study aimed to survey the characteristics of air quality and meteorological conditions in a greenway park. Methods: We measured meteorological and health related factors, including noise, particulate matter ($PM_{10}$) and selected gaseous air pollutants at three locations in a greenway park and on a general roadside as comparison. The measurements were repeated four times from April to October 2014. Results: The average air temperature in the greenway park was $20.7^{\circ}C$ which was $1-2^{\circ}C$ lower than on the general roadside. The average $PM_{10}$ concentration in the greenway park was $85.0{\mu}g/m^3$, a level 2-3 times lower than that at the roadside. The noise level at the greenway site was 4.4 dB(A)- 23.0 dB(A) lower than at the roadside. The average CO, $CO_2$, $SO_2$ and NOx concentrations in the greenway park were lower than at the roadside. The average phytoncide and anions concentrations in the greenway park were higher than at the roadside. Conclusions: The urban forest of the greenway park may have some impact on air quality and meteorological conditions.

Anisylidene nitromethane에 대한 n-butylmercaptan의 친핵성 첨가 반응의 반응기구

朴玉鉉,朴鐘玉 梨花女子大學校 韓國生活科學硏究院 1974 韓國生活科學硏究院 論叢 Vol.12 No.-

The rate-constants for the nucleophilic addition reactions of n-butyl mercaptan to anisylidene nitromethane (ANM) over wide pH range were determined by spectrophotometry and the rate equations which can fully explain the addition mechanism were also obtained. From this rate equation, the addition reaction in acid media is started by addition of n-butyl mercaptan molecule but in basic media is started by addition of n-butyl mercaptide ion. However it is not involved in Michael reaction which would be commonly expected in basic media, because ANM in strong basic media behaves as a weak acid and acid dissociation constant of ANM should be considered at the rate-equation.

Park,Eun Ok,Shin,Gun Hoon 한국무역상무학회 2012 貿易商務硏究 Vol.56 No.-

China draws lots of attention from many multinational corporations all over the world as one of the biggest market in the world. Due to the huge territory and explosive population, it is considered that China has endless potentiality. Moreover, since China joined the WTO, China opens its market, developing the policies for opening of its market. Based on the enormous purchasing power, China gets another attention in industry of electronic commerce. With the development and expansion of information technologies, China's electronic commerce has rapidly developed. Since the market of electronic commerce in China is in the developing stage, there is still a big market for electronic commerce and also Chinese government has made much effort in order to develop the industry of electronic commerce. However, in spite of these circumstances, the Chinese electronic commerce industry is far behind the developed countries. There could be many reasons for slow development in industry of electronic commerce and the main purpose of this paper is to discuss these reasons. First of all, the current status of electronic commerce industry in China will be analysed, and then, main problems of electronic commerce industry will be discussed in order to find out the reasons why the industry of electronic commerce cannot develop as much as it is anticipated. It is expected that this paper can contribute to understanding electronic commerce industry in China, and it will be helpful for companies which have a plan to extend their businesses in China.

This study was conducted to examine aspects of middle and high school students' drinking and smoking with analysis of related factors. The subjects of this study was 540 students in Kyungbuk Province. Data were collected from July, 2002 to September, 2002. The results of this study can be summarized as follows. 1. 43.6% of the boy students experienced smoking, while 12.2% of the girl students experienced it. 5.3% of the students at academy schools experienced smoking, while 44.7% of the students at vocational schools experienced it. 11.4% of the middle school students experienced smoking, while 33.9% of the high school students experienced it. 15.5% of them who lived in towns or villages experienced smoking and 38.3% of them who lived in small or medium sized cities experienced it.37.5% of the students who belonged to the lower economic class experienced smoking and 20.7% of the students who belonged to the upper economic class experienced it. 24.0% of the students who belonged to the middle economic class experienced it. It appears that the respondents showed significantly different smoking experience rates by gender, school types, grades, the number of family members, residences, and economic classes. 2. 14.5% of the respondents who lived with grandparents and parents experienced smoking and 26.5% of them who lived with parents experienced it. The smoking rate was significantly high in the groups of having one-parent, being unsatisfied with family life, making poor grades in studies, and having the father or the mother working as a salesperson. 3. 45.3% of the respondents who were unsatisfied with family life experienced smoking. The smoking rate of the respondents who were unsatisfied with it was significantly higher than that of the other groups. On the other hand, the smoking rates were not significantly different by daily life, schoolmate relation, health condition, and feeling stress. 4. According to smoking rate by frequency of drinking, 16.4% of the respondents who drank less than once a month smoked and 54.8% of them who drank more than twice a month smoked. The more frequently they drank, the higher their smoking rate was. Those who did exercise displayed significantly higher smoking rate than those who did not do exercise. Among the rates of the respondents' agonies, family disharmony was 50.5% and love problem was 39.2%. Economic condition preblem was 34.6%. It appeared that smoking was most influenced by the family disharmony. 5. The factors significantly influencing smoking experience were gender, school grade, schoolmate relation, score in studies, and exercise. From above results, it can be concluded that the students' smoking is a serious problems which can be resolved by simple approaches because it is interrelated complicatedly with gender, grade, family, school, etc. Schools, related organizations, and the government must closely work together to maximize the effectiveness of policy implementation concerning the smoking and drinking problem of the middle and high school students.

유아 그림책 「강아지 똥」에 나타난 주인공의 자아형성 과정 분석

박찬옥(Park Chan-Ok),신혜선(Shin hye-sun) 한국열린유아교육학회 2005 열린유아교육연구 Vol.10 No.3

본 연구는 Berne의 교류 분석(Transactional Analysis)의 주요개념인 구조분석(Structural Analysis) 교류패턴(Transactional pattern), 게임(game), 각본(script)의 네 가지 측면에서 「강아지 똥」을 분석함으로써 주인공의 자아형성 과정을 알아보았다. 연구 결과 주인공 ‘강아지 똥’은 주변 등장인물과 교차교류(Crossed Transaction) 이면교류(Ulterior Transaction)를 통해 자신은 아무 짝에도 쓸모없다는 자아정체감을 형성한다. 자신이 무가치하다고 생각한 ‘강아지 똥’은 타인에게 도움을 주지 못해 착하게 살수 없다는 패자 각본(Script)을 형성한다. 그러나 ‘자신도 옳고 타인도 옳다’는 심리적 자세를 가진 민들레와의 교류를 통해 긍정적인 자아정체감을 형성하게 되고 자신도 타인에게 도움을 줄 수 있다는 승자의 각본을 가지게 된다. 이것은 주인공의 긍정적인 자아정체감 형성에 상보적 교류(Complementary Transaction)가 중요함을 시시한다. This research for "Gang-A-Ji, Dong" is basically analyzed with the 4 major notions of Berne's Transactional Analysis that are 'Structural Analysis', 'Transactional Pattern', 'Game' and 'Script'. The main character of "Gang-A-Ji, Dong" is explored through these Berne's concept. As a result of study, it is noticeable that the experiences of crossed and ulterior Transaction with others affect Dong to form himself as a dirty and needless dog. He thinks himself as a worthless existence and is not capable to help others. This idea builds up a vanquished-script for Dong's life. After the Transaction with Min-Dle-Le, Dong and Min-Dle-Le exchange many thoughts. Min-Dle-Le is the character whose mental behaviour is influenced by the idea of 'I am OK. You are OK'. Their Transaction provokes Dong to have positive mind and encourage helping others. Dong's life becomes to have a victor-script. The Complementary Transaction with Min-Dle-Le is the most important part of his life for Dong, the main character to mold himself positively.

한국의 국방환경과 통일지향 국방발전 과제

박용옥(朴庸玉, PARK Yong-Ok) 신아시아연구소 2009 신아세아 Vol.16 No.4

이 글은 한반도 주변 안보·군사환경의 변화추세를 면밀히 평가하여, 그 변화의 특성을 규명하고, 이를 바탕으로 한국의 바람직한 중장기 국방발전 방향을 모색하기 위한 것이다. 한국은 세계 및 지역안보정세 변화에 맞춰 한국적 변환전략을 적극 추진하지 않으면 안된다. 첫째, 가장 절박한 당면과제는 우선 전작권전환 및 한미연합사 해체와 관련한 중장기 방위역량 보강대책을 발전시키는 일과 북한 핵을 완전히 제거하는 일이다. 현 시점에서는 전작권 전환계획의 재검토 여부와 관계없이 우리의 독자적 국방역량 강화에 전력을 기울여야 한다. 둘째, 북핵문제와 관련하여 미국의 핵우산 또는 확장억제에만 의존해서는 안 될 것이다.우리 자신의 대북핵억제수단도 확보해야 한다. 셋째, 우리 국방개혁은 첨단 high-tech 기술분야 뿐만 아니라 low-tech 비대칭위협에도 대비해야 한다. 특히 한국의 대북 비대칭위협 수단을 강구해야 한다. 넷째, 동맹관계는 전시는 물론 평시에도 중요하다. 따라서 평소부터 한미동맹관계를 잘 관리하고 유지해 나갈 필요가 있다. 앞으로 장기적인 안목에서 국제 안보/평화 이슈들에 대한 국제공조활동에도 적극 참여해야 할 것이다. 끝으로, 우리의 중장기 국방발전계획은 또한 통일에 대비한 계획이어야 할 것이다. 통일한국의 군사정책이 결코 주변국 어느 누구에게도 위해가 되지 않을 것임을 충분히 인식시키기 위한 전략대화를 적극 전개할 필요가 있다. This paper has a three-fold purpose: making an overall assessment of changing military trends in and around the Korean Peninsula, discerning some of its unique characteristics evolving in the recent past, and constructing a Republic of Korea s mid- and long-term defense development policy, particularly looking into unification. At this critical juncture, Korea s defense development policy should stand on its own transformation strategy, realistic, well-balanced, forward looking and carefully designed to reflect the current dynamics of Northeast Asian security and inter-Korean relations. First of all, most urgent and essential for South Korean security is to realize complete denuclearization of North Korea, meanwhile maintaining the solid ROKUS combined defense posture, which will supposedly be substantially loosened in the aftermath of the deactivation of the CFC in 2012. South Korean defense authority should take every measure to acquire its independent military deterrence vis-?-vis the North at the earliest possible time. Second, with respect to the North Korean nuclear problem, South Korea may well be advised not to rely solely on US s nuclear umbrella or extended deterrence, and instead move to strengthen its independent deterrence by such means as of extending its missile ranges to reach every corners of the North. Third, South Korea s defense reform should take into account not only its own subtle, high-tech capabilities but also the North s asymmetric threats largely capitalizing on crude, low-tech means. The South also needs to develop its own version of asymmetric threats to the North. Fourth, alliance relationship will continue to remain critical and essential for South Korean security and prosperity in the years ahead, not only in wartime but at peace. Thus, the ROK-US alliance needs to be well managed and maintained. South Korea also would have to more actively participate in international peace and security cooperation activities. Lastly, our mid-and long-term defense development plan should be designed and framed to prepare for a unified Korea. South Korea needs to actively engage in a wide variety of strategic communication with its neighboring countries, most particularly, China and Russia in order to enable them to understand and recognize that a future unified Korea s military posture would certainly not to be inimical to their national security interests.

박미옥,구본학,Park, Mi-Ok,Koo, Bon-Hak 한국조경학회 2012 韓國造景學會誌 Vol.40 No.4

본 연구는 어린이 활동공간이 조경공간의 하나라는 시각에서 법령 분석을 통해 어린이 활동공간 및 놀이시설과 관련된 법령 적용의 상충적 요소를 도출하고, 계획적 수단을 통해 관리할 수 있는 합리적인 대안을 제안하기 위해 수행되었다. 연구결과, 현행 제도의 문제점과 개선방안은 다음과 같다. 1. 어린이활동공간과 관련된 법령으로는 환경보건법에서 어린이 활동공간의 위해성관리, 노출평가, 환경안전관리기준 등 어린이 활동공간을 공간적 관점에서 환경안전성을 관리하며, 행안부는 어린이 놀이시설 안전관리법에서 어린이 놀이시설 설치, 검사, 안전점검 및 진단 등을 관리하고 있고, 지경부는 품질경영 및 공산품 안전관리법에서 안전인증, 자율안전확인, 안전품질표시, 어린이보호포장 등의 기준을 관리하고 있다. 2. 현행 법령에서 정한 활동공간 외에 추가 관리할 필요가 있는 공간으로 도출된 대상은 아동복지법에 의한 아동복지시설 중 '거실' 등의 실내공간, 도시공원 및 녹지 등에 관한 법률에 의한 도시공원 중 '어린이공원', 학원의 설립 운영 및 과외교습에 관한 법률에 의한 어린이를 대상으로 하는 학교 교과 교습학원 및 교습소 등의 '강의실' 등이며, 그 외에도 실내공기질과 관련하여 '$430m^2$ 미만의 어린이집 보육실'도 추가 관리가 필요한 것으로 나타났다. 3. 법령의 중복 및 지나친 규제로 인한 놀이시설의 제작, 설치, 운영과 관련된 산업계에 미치는 부담을 저감하고, 불필요한 행정력 낭비와 예산 낭비를 최소화하며, 항목간 중복되거나 상이한 기준을 일원화할 필요가 있다. 본 연구를 통해 그동안 조경분야에서는 주로 놀이기구의 제작, 수입, 설치 및 놀이시설 운영관리 등에 국한되었던 영역이 활동공간 전체를 대상으로 기구, 재료, 시설 등을 포함하는 종합적인 영역으로 확대될 수 있는 계기가 될 수 있으며, 조경 전문 분야와 관련된 엔지니어링 산업, 학술, 유지관리 산업 등의 시장확대가 가능할 것이다. This study was carried out to find contradiction factors on laws for children's activity spaces and facilities and to suggest the rational options to control and manage those spaces and facilities by environmental and landscape planning methods. The results of this study are as follows: 1. The major laws related to the environmental safety for children's activity spaces are "Environmental Health Act (ERA)" for managing the environmental safety of children's activity spaces; "Safety Supervision Law of Children's Play Facilities(SSLCPF)" for the inspection and management for safety of children's play facilities; "Quality Management and Industrial Products Safety Management Law(QMIPSML)" for managing safety certification on children's play equipments. 2. The interior space such as "living room" by the Children's Welfare Law(CWL), "Children Park" by the Act on Urban Parks and Green Spaces(AUPGS), "classroom" on private educational institutes by the Act on Establishment and Operation Private Lesson and Training(AEOPLT) and "nursing room" of child care center smaller than $430m^2$ are needed to be managed as an activity space. 3. In order to reduce industrial burden in the production, establishment, construction, and operation and to minimize unwilling extra burden in the administration effort due to legally double regulate, it is necessary to mitigate the inspections on the equipment certificate from QMIPSML and overlapped or different factors and standards must be unified. With this study, the landscape domain could he enlarged from producing, import of play equipment and establishment, construction and operation of play facilities for a comprehensive range of activity spaces, and the landscape industry such as engineering industry, academic research, management, etc.

박윤옥,박종원,Park, Youn-Ok,Park, Jong-Won 한국인터넷방송통신학회 2010 한국인터넷방송통신학회 논문지 Vol.10 No.5

2차원 그래픽을 3차원 그래픽으로 변환하기 위한 삼차원 그래픽 알고리즘들은 복잡하고 다양한 기법의 사용으로 인하여 대규모의 반복 연산이 요구되고, 이로 인하여 실시간 삼차원 그래픽의 처리가 어려운 경우가 많다. 본 논문은 삼차원 그래픽 처리와 관련된 여러 가지 알고리즘 중에서 Phong Shading 알고리즘의 병렬처리 방법과 고속 하드웨어 처리를 위한 삼차원 그래픽 가속기에 관한 것으로, Park's 다중접근 기억장치와 다수의 연산기로 구성된 SIMD처리기를 사용한 삼차원 그래픽 가속기 구조를 제안하고 있으며, 제안된 가속기 구조를 HDL을 사용한 시뮬레이션을 통해 본 논문에서 제안된 삼차원 그래픽 가속기에 의해 복잡한 알고리즘을 갖은 어떠한 삼차원 그래픽 알고리즘도 병렬 처리 알고리즘을 적용하여 SIMD 가속기에 의한 실시간 처리가 가능함을 보였다. There are many algorithms for 2D to 3D graphic conversion technology which have the high complexity and large scale of iterative computation. So in this paper propose parallel algorithm and high speed graphics accelerator architecture using Park's MAMS(Multiple Access Memory System) for Phong Shading, one of many 3D algorithms. The Proposed SIMD processor architecture is simulated by HDL and simulated and got 30 times faster result. It means any kinds of 3D algorithm can make parallel algorithm and accelerated by SIMD processor with Park's MAMS for real time processing.
