In this paper, a new measuring system is :proposed which can measure the fine 6-DOF displacement of rigid bodies. Its measurement principle is based on detection of laser beam reflected from a specially fabricated mirror that looks like a triangular pyramid having an equilateral cross-sectional shape. The mirror has three lateral reflective surfaces inclined 45$^{\circ}$ to its bottom surface. We call this mirror 3-facet mirror. The 3-facet mirror is mounted on the object whose 6-DOF displacement is to be measured. The measurement is operated by a laser-based optical system composed of a 3-facet mirror, a laser source, three position-sensitive detectors(PSD). In the sensor system, three PSDs are located at three corner points of a triangular formation, which is an equilateral triangular formation tying parallel to the reference plane. The sensitive areas of three PSDs are oriented toward the center point of the triangular formation. The object whose 6-DOF displacement is to be measured is situated at the center with the 3-facet mirror on its top surface. A laser beam is emitted from the laser source located at the upright position and vertically incident on the top of the 3-fatcet mirror. Since each reflective facet faces toward each PSD, the laser beam is reflected at the 3-facet mirror and splits into three sub-beams, each of which is reflected from the three facets and finally arrives at three PSDs, respectively. Since each PSD is a 2-dimensional sensor, we can acquire the information on the 6-DOF displacement of the 3-facet mirror. From this principle, we can get 6-DOF displacement of any object simply by mounting the 3-facet mirror on the object. In this paper, we model the relationship between the 6-DOF displacement of the object and the outputs of three PSDs. And, a series of simulations are performed to demonstrate the effectiveness of the proposed method. The simulation results show that the proposed sensing system can be an effective means of obtaining 3-dimensional position and orientation of arbitrary objects.

Early predictions of crop yields call provide information to producers to take advantages of opportunities into market places, to assess national food security, and to provide early food shortage warning. The objectives of this study were to identify the most useful parameters for estimating yields and to compare two model selection methods for finding the 'best' model developed by multiple linear regression. This research was conducted in two 65ha corn/soybean rotation fields located in east central South Dakota. Data used to develop models were small temporal variability information (STVI: elevation, apparent electrical conductivity $(EC_a)$, slope), large temporal variability information (LTVI : inorganic N, Olsen P, soil moisture), and remote sensing information (green, red, and NIR bands and normalized difference vegetation index (NDVI), green normalized difference vegetation index (GDVI)). Second order Akaike's Information Criterion (AICc) and Stepwise multiple regression were used to develop the best-fitting equations in each system (information groups). The models with $\Delta_i\leq2$ were selected and 22 and 37 models were selected at Moody and Brookings, respectively. Based on the results, the most useful variables to estimate corn yield were different in each field. Elevation and $EC_a$ were consistently the most useful variables in both fields and most of the systems. Model selection was different in each field. Different number of variables were selected in different fields. These results might be contributed to different landscapes and management histories of the study fields. The most common variables selected by AICc and Stepwise were different. In validation, Stepwise was slightly better than AICc at Moody and at Brookings AICc was slightly better than Stepwise. Results suggest that the Alec approach can be used to identify the most useful information and select the 'best' yield models for production fields.

본 연구의 목적은 차별적 경찰대응전략의 품질을 평가하는 것이다. 새로운 경찰대응시스템이 도입된 지 약 3년이 지났지만, 이를 실증적으로 평가한 연구는 미비한 실정이다. 2가지 종류의 통계적 품질관리 기법을 활용하여, 2012년 한해동안 익산경찰서에 신고된 약 3,000건의 경찰데이터를 분석하였다. "Xbar-R 관리도"의 분석결과, 경찰은 긴급출동신고전화 (Code 1)에 지속적으로 신속히(3분 이내) 대응하지 못하는 것으로 나타났다. 더불어 "P 관리도"의 분석결과, 경찰은 비긴급출동신고전화 (Code 2)에 5분이내로 대응하지 못한 출동건수의 월별 상이성이 큰 것으로 나타났다. 본 연구에서 알 수 있듯이 경찰이 추구하는 "신속한" 수준의 대응전략에 있어 코드별 목표대응시간에 대하여 재검토 할 필요성이 제기된다.

The bony notch on the inferior border of the mandible, anterior to the attachment of the masseter muscle, where the facial vessels commonly pass, has been called different names in the literature, e.g., premasseteric notch, antegonial notch, and notch for the facial vessels. Interestingly, various disciplines have leaned toward different names for this notch. Therefore, to aid in consistent communication among professionals, the present study aimed to analyze usage of these varied terms and make recommendations for the best terminology. Based on the adjacent anatomical structures used to name this notch, three groups were analyzed in this study, a group using masseter in the term, a group using gonion in the term, and a group using facial vessels in the term. A literature search found that the group using gonion in the term was found most in the literature. The orthodontics field used gonion in the term the most (29.0%: 31/107) followed by the oral and maxillofacial surgery field (14.0%: 15/107), the plastic surgery field (4.7%: 5/107), and the anatomy field (3.7%: 4/107). The dental field used gonion in this term the most (43.9%: 47/107) and the medical field used facial vessels in the term the most (33.3%: 6/18). Based on these results, the use of gonial terms for this notch seems to be preferred.

Many States such as Arizona, Texas, New Mexico, Colorado, California, New Mexico, Florida were obtained either from Spanish Empire or from Mexico. In 1848 due to the Guadalupe-Hidalgo treaty America could obtain half of the original territory of Mexico. American identity cannot be understood without the history of American expansionism further consolidated by the Spanish-American War in 1898, which brought other ex-Spanish colonies such as Guam, Puerto Rico, the Philippines to the US. The US's interest in these territories dates back to the Monroe doctrine in 1823 when Monroe "declared the Americas off-limits to any new European colonization." America justifies their expansion based on the notion of Manifest Destiny which was created by O'Sullivan at the hight of American fever to annex Texas to US. The intent of this paper is to study how Anglo-Saxon and Latin Culture clashed against each other especially right before and after the Spanish-American War. In this study the American hero, Theodore Roosevelt and Latin American hero, $Jos{\acute{e}}$ Martí will be compared, though they did not meet each other during the Spanish-American war due to Marti's early death in 1895 at the battle for the Cuba Libre. Their comparison is significant in that the former represents the American expansionist spirit and the latter the spirit of Anti-imperialism and Anti-Anglocentrism. Along with the concept of Manifest Destiny of America, 'American exceptionalism' is also mentioned which motivates U.S. to expand further even after the Spanish-American war in the form of 'informal imperialism' characterized by 'gunboat politics'of the US. These discussions will draw attention to how recent theorists such as Bryce Traister criticizes the Border Theory represented by $Jos{\acute{e}}$ David Saldívar. Here the Border Theory is criticized to repeat the discourse of the globalized capitalism which prefers the weak state and the transnational aspects by focusing on the in-betweenness of the border. In the end the paper will focus on how the Border theory as represented by Saldivar is political enough and sets up a resistant example against American expansionism of today in its focus on the call for pan-American and pluri-versal subjectivity of the borderlands. This point will be supported by a discussion of how Saldivar's view is confirmed by Walter Mignolo who advocates the "bottom up" resistance of the indigenous people of Chiapas and other social forums such as World Social Forum and the Social Forum of the Americas derived from the Zapatistas' movement whose motto is "A World in which many world co-exist."

Purpose - The Northeast Asian Logistic Hub strategy was established to create a national competitive advantage in northeast Asia. Countries in this region are competing fiercely to become the central base distribution port as the volume of container shipping continues to increase due to the northeast Asian (especially Chinese) economic growth. The primary method by which shippers are improving their customer service and distribution is enhancing profits by minimizing call ports on the key route through strategic affiliations and the use of large vessels. Each nation is planning large-scale investments in the construction of sea ports that can accommodate large vessels. This paper proposes ways by which the logistical strategies of domestic corporations can keep pace with changes in government policy concerning the Northeast Asian Business Hub policy. It examines the logistics system in the Northeast Asian region, analyzes the government's Northeast Asian Business Hub policy, and suggests logistical strategies for domestic corporations through an analysis based on a questionnaire designed to grasp domestic firms' needs and goals. Research design, data and methodology - The purpose of this study is to determine how shipping companies establish partnerships with third-party logistics providers and draws out the implications of the results. The survey methods used were personal interviews and questionnaires distributed to a sample population through e-mail, fax, mail, and telephone. A total of 600 questionnaires were distributed, of which 165 were returned. Among these, ten were excluded due to insufficient content; ultimately, 155 were used for the sample. The statistical data collection process was analyzed through data coating and a statistical package program. Results - This study argues that greater flexibility in policies, administration, and systems will be needed to significantly improve established business practices. In this dissertation, we primarily identify that in order to become a center of northeast Asian logistics, Korea must adopt a new paradigm and abandon the existing systems that are based on the economic and social systems that have stemmed from bureaucracy, inflexibility, chauvinism, and equalitarianism. Flexible policies, administration, and systems will be necessary to improve business practices. Domestic corporations must establish a strategic logistics hub and related network while simultaneously pursuing value-added logistics businesses by increasing their manpower and building a logistics information system. This will strengthen their competitive edge and lead to system improvements. Conclusions - Domestic corporations must adopt a new paradigm and use more reasonable business laws, systems, and policies that are based on market-driven flexibility and transparency. Moreover, social norms and regulations should be established to help ensure political and social security. Korea must also develop a culture of tolerance for foreign companies. Finally, the paradigm defining the policy governing the development of the capital city and its satellite cities in this context must be changed.

Purpose: This study was a predicative survey to provide home care clients with indwelling urinary catheters for furnishing basic educational material to their families by analyzing the family members' knowledge, educational needs and educational experience about indwelling catheter management. Method : The subjects consisted of 108 family members who cared for home care clients with indwelling catheters. Data were collected by home care nurses in nine hospitals in Pusan, who directly interviewed with them through questionnaires from Sep. 6th to 30th in 2004. The questionnaires for data collection were developed through pre-survey and reference review. The collected data was analyzed by using frequency, percentile, mean, variation, t-test, ANOVA on SPSS 10.1 package. Results : There were characters of home care clients with indwelling catheters: women(67.6%) were more than men; the average age of them was $69.60{\pm}14.99$ years old; neurogenic and cerebrovascular diseases(80.0%) were the most common disease group; 81.5% of them were totally dependent on others in terms of level of activity. Home care clients' families had these characters: women(76.9%) were more than men; the average age was $54.5{\pm}13.70$ years old; 46.3% of them were parents or sons or daughters in terms of relation with patient; tl1e average care period was $39.8{pm}34.20$ months. Level of knowledge about indwelling catheter management of the family members were 69.8% and its mean were $20.24{\pm}4.53$. Educational needs were 90.9% and its mean were $14.55{\pm}3.56$. Educational experience were 53.3% and its mean were $8.53{\pm}4.30$. 'Complications in using an indwelling catheter', 'Symptoms to call for a home care nurse' and 'Method to attach an indwelling catheter' were high ranked in both educational needs and educational experience. 'Anatomy of urinary tract', 'Functions of urinary tract' and 'Catheter placement' were low ranked in both educational needs and educational experience Level of knowledge about indwelling catheter management of the families showed a significant difference according to their age(F=5.35, p=0.01). Educational needs showed a significant difference according to care period(F=3.06, p=0.04). Conclusion: the family members' level of knowledge and educational experience about indwelling catheter management and their educational were not sufficient while their educational needs were high. In other words although the family members were acknowledged education needs, but the care for the patients with indwelling catheter weren't performed well because of their lack of related knowledge. Therefore systematic educational programs about indwelling catheter management for home care clients and their families should be made on the base of this study.

Sarcopenia, a common clinical syndrome in older adults, is defined as decreased muscle mass, strength, and physical performance. Since sarcopenia is associated with the incidence of functional decline, falls, and even mortality in older adults, researchers and health care providers have been keen to accumulate clinical evidence to advocate the screening and prevention of sarcopenia progression in older adults. The factors that may accelerate the loss of muscle mass and function include chronic diseases, inactivity, and deficiency in appropriate nutritional support. Among these, nutritional support is considered an initial step to delay the progression of muscle wasting and improve physical performance in community-dwelling older adults. However, a nationwide study suggested that most Korean older adults do not consume sufficient dietary protein to maintain their muscle mass. Furthermore, considering age-associated anabolic resistance to dietary protein, higher protein intake should be emphasized in older adults than in younger people. To develop a dietary protein recommendation for older adults in Korea, we reviewed the relevant literature, including interventional studies from Korea. From these, we recommend that older adults consume at least 1.2 g of protein per kg of body weight per day (g/kg/day) to delay the progression of muscle wasting. The amount we recommend (1.2 g/kg/day) is 31.4% higher than the previously suggested recommended daily allowance (i.e., 0.91 g/kg/day) for the general population of Korea. Also, evidence to date suggests that the combination of exercise and nutritional support may enhance the beneficial effects of protein intake in older adults in Korea. We found that the current studies are insufficient to build population-based guidelines for older adults, and we call for further researches in Korea.
