  • 산림의 지형적 위치에 따라 수종 구성에 차이가 있을 것이라는 가정 하에, 점봉산 일대 천연활엽수림의 세가지 지형적 위치(계곡, 산복, 능선)에 대한 천이 경향을 비교 분석하였다. 계곡, 산복, 능선에서 각각 20개씩 총 60개의 $20m{\times}20m$ 표본구를 설정하여 현재 상층 임관을 형성하는 상층목들의 수종, 수고. DBH를 조사하고 상층목 밑에서 자라는 하층목의 수종을 조사했다. 시간이 지나면서 상층목이 그 밑에서 자라는 하층목에 의해서 대치되는 천이 경향을 Markov chain의 통계학적 이론을 응용한 추이행렬 모델을 사용하여 예측했다. 연구 결과, 계곡에서는 현재 우점 수종인 신갈나무와 물푸레나무가 각각 약 23%와 약 21%의 구성 비율에서 약 200년 후에 이르게될 안정상태에 가면 두 수종 모두 약 4% 정도로 현저히 감소할 것으로 추정되었다. 반면에, 전나무, 고로쇠나무, 피나무, 난티나무 동은 안정상태에서 증가할 것으로 예측되었다. 산복에서는 약 250년 후에 이르게될 안정상태가 되면, 현재 우점 수종인 가래나무, 음나무, 피나무가 현재의 구성 비율인 15%, 8%. 15%에서 각각 2%, 1%, 5%로 현저히 감소할 것이 괄목할 만한 결과였다. 능선에서는 현재의 절대 우점 수종인 신갈나무가 58%의 구성 비율에서 약 200년 후에 이르게될 안정상태에서는 8%로 상당히 감소하고, 고로쇠나무와 피나무가 현재의 4%와 3% 의 구성 비율이 각각 20%와 40%로 증가할 것으로 예측되었다. 전반적으로 연구대상 산림은 극상 군집이 아닌 천이가 진행 중인 상태이며, 입지 조건과 식생 발달 상황에서 여러 가지의 변수가 작용하겠지만, 상층 임관의 수종 구성 상 안정상태에 도달하려면 약 200년 이상의 기간이 소요될 것으로 추정되었다.

  • While China's military rise is an issue of growing importance to regional security, it is worthwhile to note that it is not China's military modernization per se, but its capacity to project and sustain power along and beyond its borders--in particular, the possibility to resolve forcefully its outstanding maritime disputes and various contingencies. This essay argues that China's "anti-access capability"--a U.S.-coined term originally developed for a Taiwan contingency--is equally applicable to other major regional cases such as the Spratly disputes and a North Korean contingency. Furthermore, notwithstanding China's continuos efforts to develop and deploy various types and classes of weapons/platforms, it is the Russian systems and technologies that are most capable and thus likely assigned to the highest mission-critical areas. In assessing China's current and likely future military capability as well as their implications for the region, it is necessary to take note of the following: • There exists asymmetry of military capability between China and its weaker neighbors. While the PLAN is weak in several important aspects, for instance, many of its neighbors' navies are weaker still. • Some have argued that China's foreign policy behavior apparently became more "assertive" in 2009-2013, but it is wiser to keep in mind that China has almost always been assertive and aggressive when it comes to what China defines as "sovereignty and territorial issues" as well as its newest "core interests." • On the South China Sea disputes it is the function of U.S. presence in the theater--in the form of overseas bases and the freedom of navigation--and the PLA's own limitations to project and sustain power for an extended period of time that have largely prevented armed. • While Taiwan remains the idee fixe of China's diplomacy and military, it is and will be a tough nut to crack. China's recent creeping attempts for economic integration with Taiwan should be seen in this context. • China and Japan, the two regional heavyweights and traditional rivals, will likely have a bilateral relationship that is replete with difficulties and tension. China's unilateral announcement of its ADIZ in November 2013 as well as the occasional yet persistent disputes with Japan over the Senkaku/Diaoyudao/Diaoyutai islands are only the latest manifestation of this deeper and difficult relationship. • For Korean security it is imperative to take into account the geostrategic and historical factors. On top of the existing military threats from North Korea, the ROK should be able to employ a) hedging strategy, b) "limited defense sufficiency" strategy, and c) rock-solid relations with the United States.

  • 현재 기존 동상방지층 설계법에 따르면, 동상방지층은 도로 노상토의 동상특성이 아닌 온도에 따른 동결깊이에 근거해 일률적으로 결정되어 포장설계의 부실 또는 과다설계 우려가 있다. 도로는 다양한 재료와 단면으로 구성된 구조물이기 때문에 환경성과 재료 물성 뿐만 아니라 포장체 각 층의 구조적 적정성 또는 지지력을 파악하는 것이 무엇보다 중요하다. 따라서 본 논문에서는 대형 냉동고내에 실내모형토조를 구성하여 포장하부구조재료(노상층, 쇄석골재층)의 시간에 따른 온도와 동상량 변화, 동결융해에 따른 지반의 지지력 변화를 통하여 포장하부구조체의 역학적 관계를 분석하였다.

  • Background: Lung carcinoma is the leading cause of cancer mortality worldwide. Although the 5-year survival rate nearly tripled from 5-15% over the last 25 years, the estimated number of deaths still exceeds 1.3 million annually. The overall 5-year survival of lung cancer is only 10% in Europe and 15% in the United States. The aim of the current study was to determine the long-term survival and the effect of certain prognostic factors on survival of patients with lung cancer in Yazd city, Iran. Methods: In this cross-sectional descriptive study, we retrospectively reviewed hospital records and follow-up data of 148 patients with histological proven lung cancer using the cancer data registered between 1998 and 2005 in the pathology department of Shahid Sadoughi educational hospital, Yazd, Iran. Data were extracted from patient documents that included sex, age, clinical manifestations, histopathological report of the tumor and type of treatment given. Results: Overall survival time in all patients was 8.5 months after diagnosis and there was no significant difference in survival according to sex (p=0.958). Histological analysis revealed that squamous cell carcinoma was the most common histologic type (35%). Kaplan-Meier statistical methods estimated the average survival time for SCC to be better (22.6 months) in comparison with the other types of histology (all of them below 10 months). There was a trend towards significance between type of histology and duration of survival (p=0.08). Conclusion: It is reasonable to expect that early lung cancer detection, and appropriated treatment, may improve surgical morbidity and mortality. Low survival of lung cancer in our center patients show our shortages in screening programs for early diagnosis. Designing studies with larger sample size that take some other variables like staging of patients is now necessary.

  • With the current of the end of a century and social, economic, political, and cultural turbulence, people take advantage of the various ways to express their stagnation. This study introduces the term representativity and it will explain the men's fashion of the end of a century. On a theoretical basis, the concept of the representativity, image, symbol and imitation which are used as a tool for expression will be examined, and together with this, inner representation and outer representation will be categorized. The inner representation of the men's fashion in the end of a century can be taken for the purpose of connecting the image of masculinity. The image of masculinity is widely spread owing to the mass communication of a consumption-oriented society, so its hard to define that image as one thing specific. Hence, in order to discuss the male gender and mens fashion, New Man phenomenon should be noticed of. 1980's New Man influence has lasted till now. New Man images were largely categorized into two images like New Lad and Iron John after the mid 1990's. Therefore, the image of masculinity is largely classified New lad, who desires success and pursues the hedonistic life style and Iron John, who enjoys thrill and follows economical life style. The image of masculinity has influence on the outer representation how it is imitated and symbolized via many designer's works and street fashion. Two masculinity images are dominant over the men's fashion of the end of a century. One is inhumane and rational corporate power look that stems from symbolization and imitation of New Lad. The other is outdoor casual that originated from the symbolization and imitation of Iron John.

  • While the corporate practice of sponsoring major events has existed since the turn of the century, it has only recently become one of the fastest growing areas of advertising and promotion. Despite its long history and recent growth, however, event sponsorship has yet to receive the same kinds of rigorous theoretical and methodological attention that marketing researchers have devoted to other areas of advertising and promotion. Also, the recent Olympic Games in Sydney serve as excellent showcase of the sponsorship phenomenon. On the hand it becomes very clear that an event of such magnitude cannot take place without the commercial support of the sponsors. At the same time, there is a growing concern that the Olympic Games are losing their spirit and are over-commercialized because of the excessive sponsorship-linked marketing activities. At the centre of the debate is the impact and the reaction of the consumers to the growing use of sponsorship to stage major events. While the Olympic Games might be an extreme example of the growth and impact of sponsorship, the proliferation of the phenomenon is widespread across other sports events as well as other cultural and community based events. But a comprehensive model of sponsorship is not currently available in the literature. This research is the aim of the current research to investigate consumer attitude constructs towards sponsorship such as sport involvement, attitude towards the event, attitude towards commercialization. The results still have potentially significant applied and theoretical implication. First, This investigation is the first known effort, grounded in consumer behavior theory, to model antecedent variables believed to influence consumer response to event sponsorship in Korea. Second, these findings are in line with previous research, as sports involvement attitude towards the event, and attitude towards commercialization are found to be significant influences on respondents' ability, motivation and opportunity to process sponsorship information, as well as directly and indirectly impacting emotional response.

  • Many gravitational wave detectors are now being built or under operation throughout the world. In particular, LIGO has taken scientific data several times, although current sensitivity is not sufficient to detect the weak signals routinely. However, the sensitivities have been improving steadily over past years so that the real detection will take place in the near future. Data analysis is another important area in detecting the gravitational wave signal. We have carried out the basic research in order to implement data analysis software in Korea@home environment. We first studied the LIGO Science Collaboration Algorithm Library(LAL) software package, and extracted the module that can generate the virtual data of gravitational wave detector. Since burst sources such as merging binaries of neutron stars and black holes are likely to be detected first, we have concentrated on the simulation of such signals. This module can generate pure gravitational wave forms, noise suitable for LIGO, and combination of the signal and noise. In order to detect the gravitational signal embedded in the noisy data, we have written a simple program that employs 'matched filtering' method which is very effective in detecting the signal with known waveform. We found that this method works extremely well.

  • Deep sea water exists at depths of over 200m under the sea. As no sunlight reaches it, photosynthesis does not take place within it, and it contains no organic matter. In addition, its temperature is maintained at a stable low level throughout the year, so it does not get mixed with the sea water on the surface. It contains a large amount of nutritious salts, whose cleanness is maintained. It is a marine resource that has matured for a long period of time. Research into deep sea water, which started in the 1970s, has been made around the whole world, including the USA and Japan. In Korea, research has been active in this area since 2000. As there has been a good amount of research into industrial applications for deep sea water, since 1993, patents for the relevant technologies have been applied. This paper intends to provide a resource to researchers of deep sea water, by summarizing of all domestic deep sea water-related patents applied with Korean Intellectual Property Office from 1993 to 2008. This research was conducted using a computer and KIPRIS Database owned by the Korea Institute of Patent Information. 'Deep sea water' was used as the search keyword. A total of 222 Korean patents relating to deep sea water have been registered on the basis of IPC. Of these, 126 patents relate to the manufacturing and the treatment of foods, foodstuffs, or non-alcoholic beverages(A23L), while 50 patents relate to the production for medical, dental, or cosmetic purposes(A61K). 38 patents relate to water purification, treatment of wastewater, sewage and sludge (C02F), while 8 patents relate to fishery and farming(A01K). In summary, it was found that studies for the practical use of deep sea water have been conducted in relation to the manufacturing and the treatment of foods, foodstuffs, beverages, and cosmetics.

  • The concept of the true house' is based on the balance of a person's life and nature and represents the life in which lies an organic harmony between environment and ecology. However, humans have always been in a position of dominance over nature and with their developments have brought on much destruction and corruption to the ecosystem. With this, the position of the true house has intensified and the ecological approach of architecture has started to come into consideration as its alternative plan. Accordingly, it is essential to reconstruct and take on a new perspective of nature. The conversion to a more Oriental approach, which dwells in the adaptation and harmony of nature, is especially sufficient to the ecological aspect of architecture. From this we can realize that the ecological approach is none other than a modern interpretation of what our ancestors have lived by. In other words, an architectural concept deriving from the adaptation of climate, season, and nature-the coexistence of man and nature. From an ecological point of view, the idea of favoring nature in the traditional house can be found in the inclination of being one with nature by adapting to its geographical and preferable climate conditions. This results in the use of natural energy, the use of natural resources, the organic connection between the inner and outer natural space, and the application of nature itself. By approaching these elements from a modern point of view and applying it to the current time, we can open up the door to a more lasting human-environment based ecological position of architecture where our own climatic characteristics and traditions can be reflected in the pursuit of harmony between man and nature.

  • This study was from the survey on the items related to the challenges, the activity frequency of the challenged people and the places where these activities take place and the satisfaction and the demands on the facilities for the challenged people from 1,284 challenged people over the age of 20 living in Korea nation wide. From the survey, it was shown that the biggest demand lied in the improvement of the facilities related to the transportation and access for their residence and social activities. They felt they are inconvenient for the perspective of the implementation rate. Additionally, they had high desire for culture and physical educational activities. Improvements to provide convenient environments where the challenged people can access to and use the facilities as conveniently as unchallenged people do by minimizing the physical hindrances are urgently needed. For time being, many facilities for the challenged people was supplied to improve the physical environments for challenged people, however, foreign regulations had to be adopted for these job due to insufficient date on physical conditions of the challenged people in Korea. Moreover, current facilities for the challenged people emphasized more on physical aspect and the facility itself without the considerations on the overall environments, as result the improvement satisfaction and efficiency were low. More flexible and humane design approaches are needed instead of relying on supply rate and try to fully consider the characteristics of the challenged people without any discrimination.
