The paper studied the climbing structure and magnet selection method of exploration platform utilized for large-scale steel structures such as vessel surface. With respect to wall climbing robots, the study proposed a stable operation structure even in rapid incline change of vessel surface. Since the wheel-based operating method is hard to work flexibly in inclination changes, we employed joints and designed the robot to have a rotation joint in the center. The arrangement of wheels is an important aspect of this structure. Viewed from the side, the robot wheels should overlap with each other to have intersection points. The wheels here are ring-type permanent magnets and serve as a tool of attachment on walls. Based on the conditions identified through formula modeling, we proposed the required magnetic force. Important factors needed for magnetic force setup include platform weight, angle between ground and inclined plane, and friction coefficient. We considered only the required magnetic force for the stable adhesion of circular magnet while making not a separate mention about the necessary force for directional locomotion. The analysis results of ANSYS Maxwell are applied to magnetic attachment. Based on the final analysis results, we built a platform and found it did not slip and stayed attached on steel plate.

Background: Therapeutic climbing training, which originated in Germany, is a wall-hanging rock climbing-based therapy to increase the body's coordination through movement of the upper and lower limbs against gravity. However, there are no studies examining the effectiveness of therapeutic climbing training to treat balance and gait ability in patients with chronic stroke. Objectives: To investigate therapeutic climbing training program on balance and gait in patients with chronic stroke. Design: Pretest-posttest control group design. Methods: Fourteen patients with chronic hemiplegic stroke participated. Participants were randomized into the therapeutic climbing training group (TCTG, n=7) and the standard rehabilitation program group (SRPG, n=7) group. All subjects participated in the same standard rehabilitation program consisting of 60 minutes 5 times a week for 6 weeks. TCTG participated additionally in the therapeutic climbing program consisting of 30 minutes sessions 3 times a week for the same 6 weeks. Berg balance scale (BBS), Gaitview Measure, Timed up and go test (TUG) were measured. Results: In the TCTG, revealed a statistical difference in BBS between the groups; in the difference of plantar pressure ratio in the static standing position revealed a statistical difference between the groups after training; the balance ability in the one-leg standing tests increased significantly; the time in TUG decreased significantly after training in both groups; The changes in the difference of dynamic plantar pressure ratio were reduced significantly in the TCTG. Conclusion: Therapeutic climbing training contribute to improve balance and walking function in patients with chronic stroke.

This study aimed to investigate the effect of ladder-climbing exercise training on neurobiological markers in the hippocampus of mice with type 2 diabetes (T2DM). Twenty-one C57BL/6 male mice were randomly assigned to the non-diabetic control (NDC, n = 7), diabetic control (DC, n = 7), and diabetic training (DT, n = 7) groups. The DT group performed ladder-climbing training (LCT) five times a week for eight weeks. We measured the levels of hippocampal neurobiological markers (catalase [CAT], brain-derived neurotrophic factor [BDNF], nerve growth factor [NGF], amyloid-beta [Aβ], tau, and CC motif chemokine ligand 11 [CCL11]). The BDNF levels were significantly higher in the DT group than in the DC group (p < 0.05). The Aβ and CCL11 levels were significantly higher in the DC group than in the NDC and DT groups (p < 0.05). The tau levels were significantly higher in the DC group than in the NDC group (p < 0.05). However, there was no significant difference in CAT and NGF levels among the groups (p > 0.05). These results suggest that while T2DM could induce neurodegeneration, LCT may be effective in alleviating neurodegeneration caused by T2DM.

The purpose of this study was to identify the consumers’ demands on functional design of sports climbing pants. Data were collected through a field survey. 82 male and 70 female amateur sports climbers in Seoul participated. The questionnaires measured aspects of functional design in sports climbing pants, specifically motion adaptability, comfort and aesthetic value of the climbing pants. The results of this study show that comfort during climbing postures was the most important value of the climbing pants. The subjects sought motion adaptability at the hip, crotch, thigh and knee. The preferred style and degree of fit of climbing pants were differed according to gender. Men preferred loose or semi tight fit style climbing pants but women preferred the leggings style of the sport pants. The soft touch seam line and body shaping function were also important for women. The type of pants preferred for sports climbing also differed by the climbing experience period. Men began to wear the outdoor mountaineering style pants when they had experienced sports climbing for 6 months and to wear the climbing expert style pants when they had experienced sports climbing for a year. Most women wore leggings style sports pants from the beginner stage. This study also analyzed Korean market trend in 2016~2017 F/W for sports climbing pants design. The men’s pants were more likely to be designed to improve mobility compared to the women’s pants, even though the aesthetic value of the sports climbing pants was important for women.

PURPOSES: The objective of this study is to analyze factors affecting traffic accident severity for determining countermeasures on freeway climbing lanes. METHODS : In this study, an ordered probit model, which is a widely used discrete choice model for categorizing crash severity, was employed. RESULTS: Results suggest that factors affecting traffic accident severity on climbing lanes include speed, drowsy driving, grade of uphill 3%, gender (male offender and male victim), and cloud weather. CONCLUSIONS : Several countermeasures are proposed for improving traffic safety on freeway climbing lanes based on the analysis of crash severity. More extensive analysis with a larger data set and various modeling techniques are required for generalizing the results.

Three categories of basic consumer needs are functional, symbolic, or experiential (Shimp, 2010). Functional climbing wear is specially designed garment for outdoor activity and climbing movement using optimized textiles and garment making engineering process. Therefore, visible feature such as color and design could not provide sufficient information of products for proper communication between company and consumer. Product information of functional wear can be delivered to the consumers via Hang-Tag or advertising but the contents of Hang-Tag are too difficult for the consumers to understandfunctional performance of the product (Lee, Bang, & Yoo, 2014). As to advertisements of functional clothing, its contents and appeal types do not much differ from those of fashion apparel providing no functional information with celebrity models; percentage of no functional information ads were the highest (Liu & Yoo, 2014). This study stared to answer the question, ‘is functional information essential in the ads of functional clothing?’ and ‘is it successful?’ The aim of this study, therefore, was to examine the effects of functional information in the advertisements of functional climbing wear. The advertising effectiveness was measured by ‘communicability’, ‘reliability’,‘favorability’ of the advertisement and ‘awareness and reliability of product’, and ‘purchasing related influence’. For the stimulus,10 different types of advertisements were prepared by combining of the following factors: functional information (whether or not to include), appeal type (rational/emotional), and model type (celebrity/non-celebrity/no-human). For the survey, 388 adults in their 20-50’s were participated. The results showed that regardless ofappeal type or model type, functional information enhanced ‘communicability’, ‘reliability’, ‘favorability’ of the advertisement and ‘awareness and reliability of product’, and ‘purchasing related influence’. It implied the importance andnecessity of functional information in the functional climbing wear advertisement.When other variables were controlled, emotional appeal with human models,especially celebrity model, enhanced the advertising effects. Meanwhile, advertisement with rationalappeal and functional information resulted in better ‘favorability’ of ads even without celebritymodels.The finding from this study could be useful information for the functional clothing company to planstrategies for effective advertisement of their products.

Luxury industry is one of the fastest growing fields in marketing research in which many studies have examined how consumers' background affects their preference for luxury products and luxury brands. Classical theories focused on the affluent social classes and their tendency to consume luxury products to consciously or unconsciously signal their wealth. Other studies argued that the internalised culture developed during the socialisation years may influence one’s tastes and preferences for luxuries. Whereas, “costly signal theory” and “affirmation resource theory” suggest that luxury consumption extends beyond the traditional symbolic value of luxury brands and the habituated taste consumption drivers. Despite the wealth of current theoretical approaches, there is little research on the context of status rankings of luxuries and luxury brands. Thus, main objective of the present study is to develop and empirically test a conceptual framework that links consumption of at different rungs of the luxury brand ladder to a number of variables that may act as moderators which will be defined below. The key predictors are economic resources, cultural capital, perceived social status and desired status. The dependent variable is consumption of luxury brands at different rungs in the luxury ladder. A number of hypotheses are proposed and empirically tested. The dependent variable was measured by survey data collected from a sample of US consumers. The results confirm that the frequency of luxury brand purchases is significantly and positively related to consumers’ economic resources and desire for status. The hierarchy of luxury brands consumed is driven by consumers’ economic resources, cultural capital and desire for social status. Regardless of economic resources and perceived social status, consumers with high desire for social status are more likely to buy brands which represent high level of luxury. Likewise, people with higher cultural capital would buy higher luxury grading brands regardless of their economic capabilities. Moreover, results showed that perceived social status is negatively correlated with preferences for higher tier luxury brands of cars. In particular, desire for social status seems to moderates the effect of perceived social status on the hierarchy of brand of luxury car preferences. Desire for status combined with high perceived social status leads to higher preference for higher tier luxury products. It can be concluded that economic resources are responsible for the frequency people buy luxury brands, whereas cultural capital is responsible for the luxury hierarchy of the consumed brands. Frequent consumption of luxury brands reflects one’s economic status whereas the grade of luxury brands his/her cultural status. However, desire for status seems to be a key variable as it affects both frequency and the ranks of luxury brands purchased. This is an important variable as desire for status is not related with neither the actual social status (i.e., economic resources and cultural capital) nor perceived social status.

The purpose of this study was to investigate the demand for functional elements of sports climbing shirts. Questionnaire survey data were collected from adult (n=53) and adolescent (n=55) sports climbers. The questionnaire explored respondents' sports climbing activities and need for functional design features of sports climbing shirts. Their design preferences and purchasing value were also investigated. The results showed that respondents regarded ergonomic design and the use of intelligent material as important elements of expert-level sports climbing shirts. Compared to adolescent, adult respondents were more susceptive to functional design elements such as suitability for climbing motions and ease of dressing or undressing. Also, adult sports climbers were more likely than adolescents to prefer shirts that are tightly fit at the chest. Neither adults nor adolescents favored shirts design that is tightly fit at the neck or armpit. The regular shirts length not covering hips and sleeve length ending at the wrist were preferred. The collar stand should not hit the chin. Adult climbers preferred ergonomically designed sleeves on the back shoulder. Adults and adolescents had different preferences for the front neck zipper length. Adults preferred long front zipper length at chest. These findings suggest that sports climbing shirts should have functional features to prevent interference with climbing movements and improve convenience and stability.

The camera embedded wall climbing robot in this paper combines the suction and aerodynamic attraction to achieve good balance between strong adhesion force and high mobility and adopts embedded image processing technique to detect targets on the warehouse inspection. Experimental results showed that the robot can move upward on the wall at the speed of 2.9m/min and carry 5kg payload in addition to 2.5kg self-weight, which record the highest payload capacity among climbing robots of similar size. With two 11.1V lithium-polymer battery, the robot can operate continuously for half hours. A wireless camera system, zigbee protocol module and several sensors was adopted for detecting target objects and dangerous situation on the wall and for sending alarm signals to remote sensor node or manager.

PURPOSES: Climbing lanes on expressways managed by the Korea Expressway Corporation (KEC) have been hot potatoes due to conflicts between slow-moving vehicles such as trucks and other vehicles at the merging section as well as the less popularity with the slow-moving vehicles. In order to resolve such problems, KEC has altered existing climbing lanes to passing-type climbing lanes in 1999. The new type of climbing lanes showed an apparent improvement in mobility. For example, the speeds of vehicles using both climbing lane and other lanes improved a lot. However, there has been no clear evidence about improved safety. METHODS: This research effort was initiated to evaluate the safety of the new passing-type climbing lanes using the comparison-group(CG) method based on three-year-long traffic accident data sets before and after the change, respectively. RESULTS: The passing-type climbing lanes showed twice increased traffic accidents even though the traffic accidents on old type climbing lanes increased 1.1% during the same periods. In addition, in-depth study, the merging area of the passing-type climbing lanes was found out to be the weakest section where 43.8% traffic accidents out of total traffic accidents happened. It is noted that the merging area of the old type climbing showed only 25.0% traffic accidents. CONCLUSIONS : The new passing-type climbing lanes were found to be weak in terms of safety when compared with the old type climbing lanes. Especially, the merging area should be improved to reduce the risk of traffic conflicts between slow-moving vehicles and other vehicles.

오르막차로는 오르막 구간에서 속도 감소가 큰 대형차의 혼입률이 증가하여 교통용량의 감소가 크게 예상되는 경우, 고속 교통류에서 저속 교통류를 분리하기 위해서 설치된다. 오르막차로와 관련된 기존의 연구는 오르막차로의 구간선정, 시종점 위치, 설치방법 등 주로 도로설계기준과 관련된 내용에 집중되어 왔다. 그러나, 교통운영측면에서 오르막차로는 교통량이 증가할 경우 주요한 병목지점이 된다고 알려져 있는 바, 본 연구에서는 교통운영측면에서 교통량(v/c), 중차량비, 종단경사에 따라 오르막차로 일시 폐쇄가 혼잡 감소에 미치는 영향을 파악하고 아울러 적절한 교통운영기준을 수립하고자 하였다. 중부내륙고속도로 낙동분기점 부근의 오르막구간(136.9K~133.3K, 길이 3.6km, 구배 3.7%)을 대상구간으로 선정하여 교통운영변수에 따른 시뮬레이션 분석을 수행한 결과, 교통량과 중차량비가 오르막차로의 주요한 교통운영기준이 되는 것으로 나타났다. 즉, 오르막차로로 인한 혼잡을 막기 위해서는 교통량비가 0.8이고 중차량비 50%일 때 종단경사와 상관없이 폐쇄하는 것이 효과적이며, 교통량비 1.0일 경우에는 중차량비, 종단경사와 상관없이 오르막차로 폐쇄가 효과적으로 나타났다. 특히 일반적인 소통상황에서는 오르막차로 운영효과가 더 큰 것으로 나타나, 교통량 및 중차량비의 변화에 따라 오르막차로의 탄력적 운영이 필요함을 알 수 있었다. 본 연구를 계기로 도로시설의 탄력적 운영기준에 대한 연구가 활성화될 수 있을 것으로 기대된다.

본 연구는 현재 우리나라 도로에 설치되어 있는 오르막차로의 문제점에 대한 인지에서부터 시작되었다. 현재 적용하고 있는 오르막차로 설치기준은 운전자의 통행패턴이 고려되지 않아 이용률이 저조하고 합류부에 교통사고 발생 가능성이 있다. 따라서 오르막 구간의 차선설치 기준, 테이퍼 길이, 표지판 설치기준 등에 대한 연구를 수행하여 개선방안을 도출하였으며 효과검증을 위하여 고속도로에 시험적용을 하여 효과분석을 실시하였다. 그 결과 오르막차로 이용률 및 평균 통행속도가 향상되는 것으로 분석되었으며 경제성분석 결과 저투자 사업으로서 타당성이 매우 높은 것으로 분석되었다. 이러한 연구 결과를 바탕으로 고속도로 전구간 뿐만이 아니라 국도, 지방도에도 확대 적용할 경우 교통흐름 개선에 크게 기여할 것으로 판단된다.

내장산국립공원 백양사지구와 남창지구의 탐방객을 대상으로 설문조사를 통해 산쓰레기 관련 행태와 의식을 비교하였다. 미리 설정한 3개 연구가설에 의해 행락위주의 이용자와 등반위주의 이용자 그룹 간에 이용목적 등 행태의 차이와 ‘자연공원내 쓰레기통 철거’에 대한 호응도 그리고 ‘산쓰레기 처리 등 산행윤리 의식의 차이’를 검증하였다.백양사지구의 이용자특성상 연령과 거주지 및 재탐방율 등의 차별성이 드러났으며 탐방 주목적 역시 ‘자연경관감상’(백양사지구)과 ‘등산’(남창지구)으로 차별화된 결과를 보였다. 남창지구에서는 백양사지구와 달리 요구 탐방정보는 ‘쓰레기 처리정보’의필요성이 상대적으로 크게 나타났으며 등반 위주의 탐방이 이루어지는 남창지구는 도시락 지참율이 높고, 행락 위주의 백양사지구탐방객 보다 긍정적 측면에서 산쓰레기 처리에 능동적인 것으로 나타났다. ‘국립공원 내 쓰레기통 철거’에 대한 인식도 분석결과 백양사지구 탐방객은 남창지구탐방객에 비해 부정적이었으나 인지도나 만족도 그리고 불만족 이유에 대해서는 2개지구 탐방객의 의식 차이는 발견되지 않아 산쓰레기 관련 쓰레기통 철거에 대한 인식은 산행목적과는 관련이 없는 것으로보인다. 이와 함께 ‘자연공원내 쓰레기통 철거 시책’ 관련 인지도는 50% 수준을 밑돌아 “쓰레기통 철거에 따른 지속적인홍보”가 요구된다.한편 백양사지구 탐방객에 비해 남창지구 탐방객의 산행윤리는 상대적으로 강한 것으로 분석되었는데 이는 행락위주의탐방객과 등반위주의 탐방객 차이에 따른 의식의 차이로 확인되었으며 남창지구의 등반위주 탐방객은 산행 중 발생한 ‘쓰레기처리’를 중요한 산행윤리(에티켓)로 인식하고 있다는 점에서 행락위주의 탐방객과는 다른 차원의 산행 윤리의식을 보였다.

This study was conducted to investigate the relationship between the climbing up event of Luciola lateralis larvae and water temperature. In the laboratory condition, the larvae did not come out of water at constant temperature condition of 19.3 ± 0.3℃ and tried to climb up at varying temperature condition of 20~22℃ (mean temperature 20.9 ± 0.9℃) without success. However, they climbed up at constant temperature condition of 20.8 ± 0.6℃. The frequency of the larval climbing up was highest as 63.6% at 20~21℃. The most larvae climbed up at approximately 21℃ of average daily water temperature, In the natural condition, the larvae climbed up at 19.8~21.7℃ and the frequency of the larval climbing up was high as 80.4% at 20~21℃. The larval climbing up was also little observed at 19~20℃ at which no larval climbing up was found in the laboratory experiment. No larvae attempted to climb up when water temperature was below 19℃ and above 22℃. It took 18 days from climbing up of larvae to appearance of adults. In its habitat, the range of water temperature required for larvae to climb up is assumed to be 19.6~21.8℃ and the most suitable water temperature may be 20.4 ± 2.3℃. Therefore, the range of water temperature required for larvae to climb up is assumed to be 19.8~21.7℃, and the suitable water temperature range for larvae may be 20~21℃, and the most suitable temperature is thought to be 21℃.

현재 주목받고 있는 실버 소비자의 등산복 구매 실태와 만족도를 알아보고 노인 연령대에 따른 차이를 분석하였다. 본 연구 대상의 표집은 북한산에서 등산을 하고 계시는 노인 100에 대하여 65세를 기준으로 뉴실버와 실버 소비자로 노인소비자를 구분하였다. 자가응답과 대필방식을 병행하여 설문지를 작성하였으며 수집된 데이터는 SPSS 12.0을 이용하여 t Test와 카이검증을 통하여 분석하였다. 뉴실버 소비자들은 실버소비자보다 스포츠웨어를 자주 구입하였으며 구매비용도 더 많은 것으로 나타났다. 브랜드 인지도도 높았으며 구매장소는 스포츠웨어 전문매장을 선호하였다. 구매기준과 불만족 요인도 연령대에 따라 차이가 있었다. 즉 뉴실버 소비자에게는 등산복의 품질, 디자인/색에 대한 불만족이 높은 반면에, 실버 소비자에게는 품질, 착용감/쾌적감이 불만족이 높았다.
