Iwata 등은 SPN 구조에 기반한 블록 암호들 중 Serpent에 대한 의사 난수성을 분석하였다. 그들은 Serpent의 구조를 최대한 보존한 상태에서 의사 난수성을 분석하기 위하여 Serpent의 Diffusion layer의 특성을 그대로 보존하여 일반화 한 후 이론을 전개하였다. 본 논문에서는 Serpent가 취한 Diffusion layer 뿐만 아니라 SPN 구조에 기반한 블록 암호들이 취할 수 있는 임의의 Diffusion layer에 대하여 적용 가능한 일반적인 이론을 도출해낼 것이다. 또한 이러한 일반적인 이론을 Serpent, Crypton, Rijndael 등과 같은 블록 암호들에 적용한 결과를 제시할 것이다. Iwata et al. analyzed the pseudorandomness of the block cipher Serpent which is a SPN-type transformation. In this paper, we introduce a generalization of the results, which can be applied to any SPN-type transformation. For the purpose, we give several explicit definitions and prove our main theorems. We will also apply our theorems to several SPN-type transformations including Serpent, Crypton and Rijndael.

In the present paper I described the results of the observations made on the visual characteristics such as the annual ring width and summerwood percentage of Pinus koraiensis Sieb. et Zucc. grown at out university forest. The results of the study are as follows: Characteristics of annual ring width and summerwood percentage 1. The range of dispersion of annual ring width and summerwood percentage are respectively 0.5-6.5㎜ and 5-50% on the normal wood and its arithmetic mean values are each 3.0㎜ and 24% on all sample trees. 2. The values of annual ring width of heart wood are larger than that of sapwood but on the contrary the values of summerwood percentage of heartwood are smaller than that of sapwood. On the other hand variations of these values are distingushed on the heartwood. 3. The values of annual ring width due to the parts of stem with crown. with clear length and at bottom showed that the largest values are given at the parts of stem with crown. But on the contrary the summerwood percentage values are largest at the parts of stem at bottom on all sample trees. 4. The values of annual ring width and summerwood percentage depending on the stand sides are not obvious. Horizontal and vertical variations of annual ring width and summerwood percentage 5. It was recognized that horizontal (radial direction) variations of annual ring width and summerwood percentage indicated two different patterns (the region of large fluctuation and that of small fluctuation) in a tree stem. These boundaries are seemed to appear at the parts of 12-15 annual rings from pith. 6. According to the increase of height in tree the values of annual ring width increase but the values of summerwood percentage gradually decrease. 7. But vertical variations of annual ring width and summerwood percentage on the sapwood are divided into two different parts (region of increased or decreased upwards and that of remained constant in successive height) in a tree stem and these limits are seemed to appear at the 7m of height in trees. Relations between annual ring width and summerwood percentage 8. The modes of summerwood percentage related with annual ring width are seemed to appear almost in the definite range (10-25%). 9. The relations between annual ring width and summerwood percentage show a highly negatine correlation on all sample trees.

This study aims to find alternatives for a success of restaurant management. The demographic differences on restaurant location are investigated for the above objectives. It was found that the restaurant location factors are favored by different demographic profiles. First, restaurant location factors with characteristics including nearby bus and taxi stops, linear bus services and smoothed traffic, downtown area, and finally, economy development potentiality were found to be important for strategic management of restaurant. Second, places having likely to be considered as important attractiveness factors with impacts to the business performances include clustered dining-out business zone, clean area and crowded street. The above factors seem to be very important for the location strategy of dining-out businesses in cities with familiar demographic characteristics with Ulsan. This study has some limitations in the questionnaire survey. The study results may not be generalized to the nation because its research scope was limited to Ulsan City, located in the south-eastern tip of Korean peninsula. Sampling scope will need expansion in the future research as well. However, the data and their analyses are believed to be useful to the venture businessmen about to open his or her restaurant to evaluate the location attractiveness for money-making and in particular to people in cities with familiar demographic characteristics like Ulsan. The study results are hoped to be readable to the interested in the restaurant business.

A study on the wood quality from planted Pinus koraiensis Sieb. et Zucc. has been undertaken by the University Forest in order to gain results of the gross structural features of stem. For this study some groups of trees were felled and several characteristics such as the degree of stem, slenderness, eccentric growth, heartwood diameter, height of butt sweep and butt-swell were analyzed. The results of the study are as follows. 1) The relation between diameter of log and its height in sample trees are nearly parallel to each other. But their degrees of slenderness in logs cut from intermediate and codominant trees are some what gentle as compared with that of logs from dominant tree. 2) The eccentric growth at transverse section of sample trees is generally decreased with the increase of tree height on all sample trees. 3) On the eccentric growth at transverse section of tree, a rather distinct tendency was noticed that all of sample trees showed the direction of eccentric growth in R₂ side. 4) Heartwood diameter appeares to become larger as tree growth decrease under same diameter of logs and log diameter in which heartwood appeares is larger in rapid growth rate trees. 5) The maximum height of butt-sweep generally shows that the larger the breast height diameter of tree is, the smaller its height becomes. On the contrary it was noticed that the larger the breast height diameter of trees, the higher the maximum height of butt-swell became. The direction of butt-sweep and butt-swell were shown in R₁ side in all sample trees.

의료기관의 서비스공정성이 의료서비스 만족과 고객충성도에 관한 연구

이원일(Lee, Won-Il),윤기창(Yoon, Ki-Chang),장광희(Jang, Kwang-Hee) 한국물류학회 2015 물류학회지 Vol.25 No.4

본 연구는 의료서비스 시장에서 의료기관 간 경쟁이 심화되는 시점에, 공정성이 고객만족도에 영향을 줌으로써 충성도를 향상 시켜 경쟁력을 회득할 수 있을 것이라는 가정 하에 이론적 연구와 실증적 연구를 통해 구조적 인과관계를 규명하고자 하였다. 특 히, 고객만족을 본 연구에서 인적서비스와 물적서비스 부문으로 나누었는데, 기존의 연구와 달리 물적서비스만족도는 의료기관의 외형적인 특성이 아닌 의료장비에 초점을 맞추어 변수를 개발하여 실증분석을 하였다는 점에서 차별성이 있다. 본 연구를 위해 리서치기관이 보유하고 있는 패널들로부터 자료를 수집하고, 이론적 연구를 통해 설정한 공분산구조모형에 따 라 AMOS 22로 실증분석을 실시하였다. 본 연구의 실증분석 결과로서 의료서비스의 공정성은 인적서비스만족도와 물적서비스만족 도에 유의한 영향을 미치는 것으로 나타났고, 인적서비스만족도는 재방문의도와 추천의도에 모두 유의한 영향을 미치는 것으로 나 타났다. 물적서비스만족도는 재방문의도에 유의한 영향을 주는 것으로 나타났지만, 추전의도에 미치는 영향은 유의수준 0.05에서 유의하지 않았으나, 유의수준 0.10에서는 유의하게 나타났다. 본 연구의 시사점은 공정성(분배공정성, 절차공정성, 상호작용공정성)을 높이기 위한 노력은 이용고객의 만족도를 높이게 되며, 결국에는 고객충성도가 높아지기 때문에 의료기관의 종사자뿐만 아니라 의료기관이 보유한 의료장비에 대해서도 고객들에서 유용성을 알릴 필요가 있다는 것이다. The research was analyzed through the structural equation model about an effect how the justice of medical service influences on customer satisfaction and customer loyalty. Prior researches separated human factor and physical factor in measuring service satisfaction. Especially, even though the physical factor was used in environmental aspects of service providing institutions, there are distinctions from the view that medical equipments are important as well as human service in the medical institutions. The model of this research classifies the justice from distributive justice, procedural justice, and interactional justice. In addition, the study analyzed the effect of the justice on human social services, and physical service satisfaction, and the effect of the service satisfaction on re-visiting intention and oral traditional intention. Consequently, this study showed that justices positively impact on the human social service, and physical service satisfaction. The human social service beneficially affects the re-visiting intention, and oral traditional intention. In contrast, the physical service satisfaction also influences on the re-visiting intention, but it resulted that the physical service satisfaction has no relationship with the oral traditional intention. Thus, customers who perceive the justices have high customer satisfaction, and customer loyalty in a portion. However, resulting of the little relationship between physical service and oral traditional intention shows that medical institutions need to enhance the communication regarding the effectiveness of medical equipments toward customers.

북핵문제에 대한 중국의 정책

이원봉(Wonbong Lee),이시형(Shihyung Lee) 한국정치정보학회 2004 정치정보연구 Vol.7 No.1

북한의 핵개발이 국제사회의 이슈로 등장한 것은 1993년과 2003년이다. 1993년 북핵문제는 북한과 미국간의 북미 회담으로 합의를 보았다. 그러나 2003년도의 북핵문제는 3자회담, 6자회담과 같은 다자회담의 성격으로 해결해 나가고 있다. 최근의 북핵문제 해결에는 중국이 중재적 역할을 하고 있다는 점이 특징이다. 북핵개발에 가장 큰 우려를 하고 있는 국가는 중국이다. 중국은 북한의 핵개발이 동북아 안보정세를 악화시킬 수 있고 동북아지역 국가들의 핵확산에 영향을 줄 것을 우려하고 있다. 중국의 국가목표는 경제발전을 통해 국력을 증대시키는 데 있다. 이러한 국가목표 하에 한반도 정책의 방향을 설정하고 있다. 즉 한반도의 안정과 평화, 남북한에 대한 균형자적 역할, 한반도에서의 중국의 역할 증대 등이 중국의 대한반도정책 방향이다. 중국과 북한과의 관계는 과거와 같이 이념에 의한 혈맹적 동맹관계에서 벗어나고 있다. 양 국 관계는 전략적 관계, 실용적 관계를 지향하고 있다. 이러한 중국의 국가목표, 한반도정책, 북중관계의 성격은 중구그이 북핵정책을 이해하게 하는 중요한 요인들이다. 중국은 북핵문제 해결에 적극적으로 참여해서 북한의 핵개발을 억제시키고, 이를 통해 주변 지역의 안정을 도모하고자 한다. 더 나아가 미국과의 관계를 개선시키고 한반도와 동아시아지역에서 중국의 영향력을 제고시키고자 한다. 따라서 중국은 6자회담과 같은 다자회담에 중재적 역할을 통해 더욱 적극적으로 참여하고 있다. In 1993 and 2003, North Korea's nuclear bomb has been an issue in an international society. In 1993, the issue was seemed to bring a peaceful settlement by the conference of Unites States and North Korea. In 2003, however, a settlement of the issue was shifted to the multi-nation conference such as three or six nation conference. Recent special feature of the issue is that China has a role of arbitration for the settlement because China is very anxious for North Korea's nuclear bomb development. China has a conclusion that North Korea's nuclear bomb can make worth the north-east area's security circumstances and affect to the nuclear proliferation among the north-east countries. China's national goal is to build up national power with economic development. She is formulating the bearings of Korean peninsular policy based on the national goal. China's Korean peninsular policies are such as Korean peninsular's peace and equilibrium, equivalent role to the South and North Korea, and enlarging China's role in Korea. The relationship between China and North Korea is being changed from the past ideological blood pledge. Both countries are seeking for the strategical and practical relationship. China's national goal, Korean peninsular policy, and relationship with North Korea are important factors to understand her policies to North Korea. China actively involves in suppressing North Korea's developing nuclear bomb for contriving to settle down stabilization of near areas. In further more, China is seeking for improving the relationship with United States and enlarging her power of influence to the Korean peninsular and East-Asian region. Therefore, With an arbitrating role China participates more actively to multi nation talk such as six nation conference.
