The purpose of this study was to compare selected kinematic variables between male medalists and a Korean male javelin thrower at the IAAF World Championships, Daegu 2011. The three medalists and one Korean javelin thrower that participated in the Championships were videotaped using three high-speed cameras (300 frames/s, EX-F1 Exilim, Casio, Japan). The results showed that the release and attitude angles of the Korean male javelin thrower (KMJT) were greater than that of the medalists, whereas the attack angle of the KMJT was smaller than that of the medalists. This study also found that the KMJT clearly had a lower release height than the medalists. As a possible adaptation of his physique to the skill, the KMJT used a small trunk inclination angle and produced greater inclination angles at his upper extremities. These results may be linked to an increase in the release angle of the KMJT. There were some difference between the KMJT and the medalists in terms of the length and duration of the delivery phase. In harmony with the shorter length of the delivery phase, its duration was shorter for the KMJT in comparison to the medalists. Because the delivery stride is considered to be a primary generator of endpoint speed, this decrease in the delivery phase time would decrease the javelin velocity at release. The amount of time taken in the delivery phase may be a critical factor to enhance a javelin thrower's performance. Thus, rhythmic movement training specifically designed for the KMJT will help him attain an optimal throwing position.

Now it is not useful the theory about civil-military relationship that have been analysed for power games between military and civilians Korean society is going on governance society managed by cooperating network of government, civilian society and business market These social change require for new context about civil-Military relationship. Military leadership must contribute desirable civil-military relationship This study will suggest the direction about military leadership for desirable civil-military relationship. Now political issues about military intervention to the government are almost settled, but the worry about complications between military and civilians exist in the part of low issues like policy-making. Another important issues is military leadership about the style of social-being. In recent years, social change is very complex and speedy like global networking and diversity, leadership environment also, changed like leadership paradigm shift. Military leadership must be examined from the principle to the context of social integration At the present age, individual soldier is citizen in uniformed. Also military leadership must to seek the principle in the citizen mind like citizenship. Another charactristics of present day military is influence of high technogy. For the high-tech war military need the transition about science and technology from the whole society. In the context of above the development of military leadership are suggested as follows. First, the development of military control leadership must besought to the context of cooperation between government and military. Government must provide the system to strengthen military professionals in the process of policy-making about national security Second, military leadership must embody the important social values through the advanced military making, Third, military leadership must provide the adaptability to the society through the military education of their soldiers Forth, military leadership must be contributed to the social integration and to the growing up individual soldiers like their socialization and their achievement. Five, an important subject of military leadership is the creation of desirable military culture through the harmony of social culture and military culture.

Fashion is very superficial. However, it is expressed through the culture that is a cause of internal change and therefore its contents are defined by the cultural features. In this study, to study the aesthetic properties of the French fashion, the internal fashion contents are defined according to the cultural characteristics of France and based on the definition, the external features are investigated. The cultural characteristic was analyzed based on the reference literatures on the French culture. Based on the cultural characteristics of France, the aesthetical properties of the contemporary French fashion can be analyzed as follows: ${\cdot}$Dualism is the internal contents of the French culture with multiple sources, and it implies that opposing values such as female and male, traditionalism and modernism, simplicity and decoration are coexisting. Simplicity is pursued but decorative elements are in harmony and new phase of time is reflected while certain style has lasted for a long period of time to become a tradition. Furthermore, a rational trend combining masculinity and femininity, simultaneously exist with a trend that emphasizes feminine image. ${\cdot}$Multiculturism is a mysterious feature that has adapted the oriental or other cultural factors into the forms, patterns, colors and material of costumes. It has also been reconstructed with the French and the modern tastes. ${\cdot}$Avant-gardism is pursuing a novel aesthetic value against the former value system. It recognizes the human body as an object of figurative arts therefore emphasizes the body with geometric shapes to deny the fixed-idea, or engraft new materials and technologies to express the futuristic aspects.

This study comprehends that the landscape of Ipsan Village is the accumulated output of the landscape management and social behavior by the historic personages through the reference research and field surveys. And the study sorted out the over-layered landscape characteristics of Ipsan Village by analyzing the dispersed landscape elements as follows. First, right before the start of Japanese invasions to Korea(1592-98), Tamjin(耽津) An(安) Family moved into Ipsan and started establishing the a single clan village. At a site with mountain background and facing the water(背山臨水), the village used to be a typical farming one with an organically planned road-system and housing area following the traditional order. However, the landscape has changed drastically since the 20th century with the construction of banks, roads and readjustment of arable land etc. Second, the original landscape, which can be figured out through the 'Gosanjaesibyukgyeong(高山齋十六景)' in the 18th century, shows its harmony with natural landscape: mountain & valley, stream & field, traditional trees, etc, cultural landscape: village, well, spring, etc, and momentary landscape: seasons, time, weather phenomena, sound, behavior, etc. Third, based on the second, 16 natural landscape elements: mountain & stream, planting, etc. and 25 cultural landscape elements: housing spaces, self-cultivation & ceremony spaces, community spaces and modern education & enlightenment spaces were selected and interpreted as landscaping meanings. Fourth, the over-layered landscape which stems from the compositive functions and inter-connectivity of landscape elements which consists Ipsan Village is regarded as 'Natural geographical and Fungsu landscape', 'Rural production and livelihood landscape', 'Confucian ceremony and symbolic landscape' and 'Modern education and enlightenment landscape.'

Purpose: This study aims to develop menu for tofu, which will satisfy a variety of needs of people by harmonizing tofu and other ingredients. Methods: In the present study, the standard recipes were made for tofu menu development by improving the existing recipes like Dubu-seon, Dubu-kimchi, Dubu-jeongol, and Sundubu-jjigae (soft tofu stew). Based on newly developed recipes, the nutritional analysis was conducted using the analyzing program of the Korean Nutrition Society (CAN-Pro 4.0). Food styling was devised considering the shape and color of plates, layout, and color harmony. Table design was devised empirically employing tablecloth, napkin, dinnerware, glasses, cutlery, centerpiece, and figures. Results: Food styling of Dubu-seon was devised by improving the visual aspect, using Korean traditional five cardinal colors. It turns out that the improvised version of Dubu-seon (prepared following the new recipe) can satisfy 15.1% of amount of recommended dietary fiber intake per day for both male and female adults. In case of Dubu-kimchi, the dish was developed as a one-dish meal by supplementing protein and improving food styling. Beef was added in a form of a meatballs which is especially preferred by children. However, the amount of salt was reduced due to the strong and spicy taste of kimchi itself, resulting in 32% of daily intake of sodium. Dubu-jeongol was also improvised by reducing protein content, and more vegetables were added. Food styling was also improved. Concerning Sundubu-jjigae, protein was supplemented by addition of mushrooms rather than the existing way of adding shellfish. The sodium content was 133.88 mg, which is merely 10% of daily intake. Conclusion: With the new developments in tofu menus, new food styling, and table design, this study aims to contribute towards the rise in sales in the food service industry in terms of being used as basic and critical data.

The design of cluster-based routing protocols is necessary for Wireless Sensor Networks (WSN). But, due to the lack of features, the traditional methods face issues, especially on unbalanced energy consumption of routing protocol. This work focuses on enhancing the security and energy efficiency of the system by proposing Energy Efficient Based Secure Routing Protocol (EESRP) which integrates trust management, optimization algorithm and key management. Initially, the locations of the deployed nodes are calculated along with their trust values. Here, packet transfer is maintained securely by compiling a Digital Signature Algorithm (DSA) and Elliptic Curve Cryptography (ECC) approach. Finally, trust, key, location and energy parameters are incorporated in Particle Swarm Optimization (PSO) and meta-heuristic based Harmony Search (HS) method to find the secure shortest path. Our results show that the energy consumption of the proposed approach is 1.06mJ during the transmission mode, and 8.69 mJ during the receive mode which is lower than the existing approaches. The average throughput and the average PDR for the attacks are also high with 72 and 62.5 respectively. The significance of the research is its ability to improve the performance metrics of existing work by combining the advantages of different approaches. After simulating the model, the results have been validated with conventional methods with respect to the number of live nodes, energy efficiency, network lifetime, packet loss rate, scalability, and energy consumption of routing protocol.

Mt. Umyeon is a low-altitude mountain near a residential area, and the actual forest area is not large due to the fact that development for use as a living green space is being completed and in progress across the mountain, so the buffering action for landslides was weak. The unit was located at the top of Mt. Umyeon, and there were reports of contents related to the military unit in some accident areas. Some experts suggested that the landslide that started on the cut side of the unit could be one of the causes of the landslide at Mt. Umyeon. It is presumed that there was a sudden collapse of trees that had fallen due to erosion inside the valley. In the case of the Umyeon landslide, localized torrential rain is the biggest cause, but the fact that it suffered a lot of damage is the result of no preemptive measures. In particular, it can be said that the damage was caused by the concentration of residential and commercial facilities due to the unplanned urban expansion without prior review of the feng shui geography of settlement areas. The important lesson we have learned is that we should recognize nature as living things and live in harmony and coexistence between humans and nature through understanding and cooperation. Adapting to changes in the environment can survive, but if it doesn't, it will be slaughtered. As such, geography influences changes in feng shui. Changes in feng shui have a profound effect on not only humans but also the natural ecosystem.

본 연구는 호흡마사지법으로 생체에너지(기) 순환을 고찰하고자 하였다. 수 천 년 전부터 자연과의 조화를 통해 깨달음을 얻은 선조들은 자연호흡법으로 기에너지의 생성과 승강운동조절을 통하여 무병장수 하였으며, 춥고 배고픈 시절에 복부의 소중함을 체험한 할머니는 부드러운 약손으로 생명의 바다인 복부를 통해 질병을 치유해 주셨다. 이처럼 자연호흡과 할머니의 부드러운 약손의 감성인식 및 동양의학의 핵심내용인 기일원론(氣一元論)의 바탕으로 배꼽호흡테라피가 형성되었다. 자연호흡과 약손 마사지로 기에너지의 생성과 승강운동을 통하여 복부를 다스려 자연계와 인체내 외의 동태적 평형상태를 유지시킴으로써 몸과 마음의 변화를 가져와 자연스럽게 질병을 치유하여 신체의 항상성을 유지시켜주는 자연치유법이라 할 수 있다. 배꼽호흡테라피를 적극 활용될 수 있는 실무 확산의 계기를 마련하고, 이를 통해 과학적인 임상연구 실무적용에 널리 활용될 것으로 기대한다.
