Earthworms have been employed in traditional oriental medicine for the treatment of neurological disorders, as anticonvulsants, analgesics, and sedatives. In fact, earthworms are currently used as a medicinal agent in China, South Korea, Japan, Taiwan and North Korea. However, both the species and the genus of the earthworms registered in the pharmacopoeia of each country are different. Neural injury is induced by oxidative stress, inflammation, and apoptosis. The role of various synthetic chemicals of earthworms as antioxidant and anti-inflammatory agents have been studied and earthworm extract and its components have been shown to protect nerve cells and restore nerve function in various preclinical neuronal damage models. We employed earthworm extracts to provide prevention and treatment strategies for many neurodegenerative disorders including Parkinson's disease, mild cognitive impairment, cerebral infarction, and peripheral nerve damage. In this study, we investigated the effects of earthworm extracts and its components to explore their prophylactic and therapeutic effects in various neuropathic models. We used earthworm resources to provide prevention and treatment strategies for many neurodegenerative disorders including Parkinson's disease, mild cognitive impairment, cerebral infarction, and peripheral nerve damage. We summarized the protective effects of both earthworms and their extracts on neuropathies. The current study identified some earthworm components to be used in treatment and prevention strategies for nerve disorders and could be helpful for the development of new therapies for intractable diseases.

Background: Despite muscle latency times and patterns were used as broad examination tools to diagnose disease and recovery, previous studies have not compared the dominant arm to the non-dominant arm in muscle latency time and muscle recruitment patterns during reaching and reach-to-grasp movements. Objects: The present study aimed to investigate dominant and non-dominant hand differences in muscle latency time and recruitment pattern during reaching and reach-to-grasp movements. In addition, by manipulating the speed of movement, we examined the effect of movement speed on neuromuscular control of both right and left hands. Methods: A total of 28 right-handed (measured by Edinburgh Handedness Inventory) healthy subjects were recruited. We recorded surface electromyography muscle latency time and muscle recruitment patterns of four upper extremity muscles (i.e., anterior deltoid, triceps brachii, flexor digitorum superficialis, and extensor digitorum) from each left and right arm. Mixed-effect linear regression was used to detect differences between hands, reaching and reach-to-grasp, and the fast and preferred speed conditions. Results: There were no significant differences in muscle latency time between dominant and non-dominant hands or reaching and reach-to-grasp tasks (p>.05). However, there was a significantly longer muscle latency time in the preferred speed condition than the fast speed condition on both reaching and reach-to-grasp tasks (p<.05). Conclusion: These findings showed similar muscle latency time and muscle activation patterns with respect to movement speeds and tasks. Our findings hope to provide normative muscle physiology data for both right and left hands, thus aiding the understanding of the abnormal movements from patients and to develop appropriate rehabilitation strategies specific to dominant and non-dominant hands.

The use of Project Management Information System (PMIS) is increasing in project management industries such as construction, defense, manufacturing, software development, telecommunication, etc. It is generally known that PMIS helps to improve the quality of decision making in project management, and consequently improves the project performance. However, how much and which parts of project management performance are affected by PMIS still need to be studied further. The purpose of this study is to investigate the impact of PMIS quality on project management performance. We collected data from various project based industries such as construction, defense, manufacturing, software development and telecommunication by using survey questionnaire. PMIS quality was measured in three dimensions. They are system quality, information quality and service quality. Project management performance was measured in nine variables such as time reduction, work accuracy, cost management, etc. Statistical analyses such as multiple regression were used to analyze the data. The results showed that PMIS quality had significant impacts on the project management performance and user satisfaction. It was notable that only two dimensions out of the three PMIS quality dimensions, system quality and information quality, affected the project management performance. Also, it was found that PM performance played a mediating role between PMIS and user satisfaction, and between PMIS and reuse intention. The contribution of this research is that it helps to clarify what aspects of PMIS affect the project management performance and user satisfaction.

최근에는 게임을 플레이어가 직접 즐기는 것 뿐만 아닌 인터넷 방송을 통해 시청하는 경우도 늘어났다. 따라서 예전처럼 기술력을 바탕으로 한 화려한 그래픽뿐만 아니라 플레이어 또는 시청자에게 인상 깊은 스토리를 전달해주는 것 또한 중요해졌다. 본 논문은 게임에서 스토리를 전달하는 방법 중 퀘스트를 인터랙티브 스토리텔링을 고려하여 레벨디자인 할 수 있는 저작도구를 설계하고 구현하였다. 구현된 퀘스트 레벨디자인 저작도구는 NPC, 필드(몬스터), 아이템과 같은 배경 설정을 한 뒤 이들을 연결해주는 인터랙션 설정을 마치면 여러 유형의 퀘스트가 설정해준 내용을 바탕으로 생성된다. 이러한 방식으로 생성된 퀘스트는 인과 관계가 명확하여 플레이어로 하여금 퀘스트의 내용을 쉽게 납득할 수 있도록 도와준다. 또 퀘스트 레벨디자인 저작도구는 프로그래밍을 모르는 기획자도 쉽게 사용할 수 있고 이를 이용하면 시간과 비용이 많이 드는 퀘스트 기획, 제작에 사용할 수 있을 것이다.

With the increasing interest among modern people in the environment and leisure activities, the social demand for parks and green spaces is increasing. Thus, with the increase in park consumers, it is necessary to systematically investigate and analyze user characteristics and demands and continuously reflect them in park management to increase user satisfaction. Therefore, this study focused on Central Park in Dongtan 1 New Town, Hwaseong City, to analyze and evaluate what variables affect users’ behavior and satisfaction and suggested ways to construct future neighborhood parks. After theoretical considerations, the site was investigated and analyzed, and user behavior and satisfaction were studied through surveys and in-depth interviews. The results showed that user satisfaction with the Central Park was generally high, and the park had a large positive effect on the satisfaction with the residential environment among residents. It seems that the psychological and mental satisfaction provided by the park, which relieves mental and physical stress in modern people’s busy lives and supports static and dynamic recreational activities, will be high. It was judged that if user demands are more actively reflected upon, user satisfaction can be increased, and parks can be vitalized.

Background: High string instrument (violin, viola) players are at high risk for developing musculoskeletal problems. In particular, a higher prevalence of shoulder problems has been reported. However, evidence of the effectiveness of therapeutic exercise for musicians with this condition is lacking until now. Objects: This case series study investigated the effect of a specific exercise program on shoulder pain, dysfunction, and posture of professional orchestral high string musicians.

The shoulder pain and disability Index and the performing arts module-quick disability of the arm, shoulder and hand scale decreased by 71.72% and 51.61% respectively. The exercise program improved function and posture. Conclusion: A specific exercise program for high string players was effective in managing shoulder pain. This case series is intended to provide empirical data on the effectiveness of an exercise program aimed at assessing the effect of exercise on pain, dysfunction, and posture of professional orchestra musicians associated with specific instrument groups.

게임에서의 스토리는 상호작용 할 수 있는 인터렉티브 스토리텔링이라는 점에서 사용자의 몰입을 유도한다. 이러한 인터렉티브 스토리텔링은 기존의 이야기의 선형 구조와 달리 비선형 구조를 띄고 있기 때문에 기존의 서술구조와는 다른 서술구조가 연구되어왔다. 크게 사건 중심인 트리 기반 서술구조, 제약 기반 서술구조, 캐릭터 중심인 캐릭터 기반 서술구조가 있다. 트리 기반 서술구조는 HTN, HSP등 여러 알고리즘으로 발전되었고, 분기가 많을수록 트리의 크기가 커진다는 단점과 이야기의 자유도가 떨어진다는 단점이 존재하였고, 캐릭터 기반 서술구조의 경우 사건이 아닌 캐릭터를 설계한 다음 캐릭터가 자유롭게 행동하게 하여 이야기를 진행하는 방식으로 사용자가 몰입하는 대상이 캐릭터라는 점에서 게임에 더 적합할 수는 있지만, 캐릭터의 행동을 세밀하게 설계하기 힘들다는 단점이 존재한다. 본 연구는 이 중 제약 기반 서술구조를 전체 이야기의 흐름 파악과 다양한 사건전개가 용이하도록 새로운 태그들을 제시하여 재설계하였다. 새롭게 제시된 <event>라는 태그는 이야기의 흐름 파악을 쉽게 할 수 있게 하고, <plot>이라는 태그는 다양한 사건전개가 용이하도록 설계되었다. 제안하는 서술구조를 이용하여 예시로 이솝우화 중 토끼와 거북이에 적용하였다.

The cooperative relationship between Employer and Contractor in the construction industry is the most important factor to achieve the project success. Employer shall draw the Contractor’s cooperative behavior during executing the project. A study on the impact of the Owner’s power on the contractor’s cooperative behavior is rare in the construction industry in Korea even though the negative impact of the high-power distance between the Employer and the Contractor has been a hot issue in Korea. In this empirical study, it is shown that the Employer’s power can address the contractor’s cooperative behavior. The respondents were mostly employees in the domestic construction companies who have experienced in the construction projects. The total number of respondents was 317 effectively. The multiple regression analysis using SPSS 21.0 were conducted to verify the hypotheses. In conclusion, the Mediated Power is positively associated with the In-Role Behavior and with the Extra-Role Behavior. Some of Non-Mediated Power is positively associated with the In-Role Behavior and with the Extra-Role Behavior. It seems that the Contract underestimate the Employer’s Expert Power. It was known that the cooperative power caused by Non-Mediated Power is good for long term relationship of the business to business transaction. So it is highly recommended that the Employer shall foster its expertise.

The purpose of this study is to investigate the effects of no planning and online planning on complexity, accuracy, and fluency (CAF) in L2 spoken and written tasks. The study was designed into 2x2 with two independent variables: planning conditions (no planning and online planning) and task modality (speaking and writing). First, 80 Korean EFL undergraduates performed two tasks in a laboratory setting: a proficiencyassigning narrative spoken task and a randomly assigned main task. The main task had four different conditions: no planning in speaking, online planning in speaking, no planning in writing, and online planning in writing. The participants’ spoken and written performances were measured and analyzed for syntactic complexity, accuracy, and fluency. The findings demonstrated that the no planning (NP) group improved accuracy and fluency significantly more than the online planning (OP) group in the spoken task and that the NP group improved their fluency more than the OP group in the written task. Additionally, in both planning conditions, the written task increased accuracy more than the spoken task, whereas the spoken task increased fluency more than the written task. It is hoped that these findings will facilitate understanding of the supportive role of planning in task manipulation in terms of L2 learners’ limited attentional resources and its relationship with linguistic performance.

The purpose of this study is to improve effectiveness of Korea’s Official Development Assistance (ODA) provided to developing countries. To do this, we analyze the efficiency of ODA provided to 38 recipient countries by Korea through data envelope analysis method. The effects of four factors including population, GDP, economic decline and poverty, and external intervention on efficiency are also investigated by utilizing tobit regression analysis. As a result of the DEA efficiency analysis, it is found that the average efficiency score of the total is about 59%. By region, the average efficiency score of Asia, Africa, Central and South America, and the East and CIS (Commonwealth of Independent States) are about 42%, 68%, 70%, and 74%, respectively. It indicates that the Asian countries are inefficient compared to countries of the other regions. It is also found that factors of population, GDP, economic decline and poverty, and external intervention have statistically significant effects on efficiency at 0.01 significance level. In the case of the population, the higher the population of the recipient country, the more negative (-) effect is on the efficiency. The other factors such as GDP, economic decline and poverty, and external intervention have positive effects on the efficiency.

This study aims to contribute to the development of sports wearables. It was conducted by a convergence team of professionals in the fashion industry, kinesiology and sports studies, and computer science and engineering. The purpose of the current study was to design and develop a fabric-type fitness band for a sensor to measure acceleration during jump rope exercises. Computer science and engineering professionals developed the Arduino board and sensor, kinesiology and sports studies provided the necessary exercise protocol, and the fashion industry professionals developed the band. First, a fitness band preference survey was completed by men and women between the ages of 20 and 50. Typical uses of the band included tracking exercise amount as measured by the number of steps taken and calories burned. Strap watch closure, a single color and achromatic color, and soft and smooth touch materials were preferred as band design. Second, two fabric-type fitness bands were designed and developed. Design 1 had a 3-dimensional pocket for the sensor, bright blue color, and stretch binding around the edges and for a loop. Design 2 had a flat pocket for the sensor, achromatic color, mesh binding around the edges and two metal loops. Both designs had Velcro as a closure. Third, wear testing of both bands with the sensor were conducted of 15 women in their 20s. They wore the bands during jump rope exercises. Both bands generally satisfied the participants. The Design 2 band was slightly more satisfying than the Design 1 band.

The purpose of this study is to comparatively examine techniques and expressive characteristics of batik by focusing on the work of DanZhai and that of ZhenNing Buyi. We collected 50 pieces of batik each from Miao and Buyi in Chinese GuiZhouSheng and then analyzed their colors and patterns. The findings show that most of Miao’s batik had deep and soft tones, while that of Buyi most often had blackish tone since the number of dyes in the latter is higher than that in the former. Miao often used patterns expressing animals or animals and plants, while Buyi frequently used geometric ones. An examination of specific motifs demonstrated that butterflies, fish, and flowers were most often used by Miao, while dots, vortexes, lines, and lozenges were frequently utilized by Buyi. For expressive techniques, both Miao and Buyi commonly used simple stylized expression or complex expression combining stylized and geometric techniques. Maio’s motifs were often decoratively expressed with delicate curves, while Buyi’s motifs had simple structures, so pictures were neatly expressed with thick lines and wide and simple planes. For the composition of the motifs, incomplete symmetry between top and bottom and between left and right often appeared in Maio, while in Buyi complete symmetry was frequently shown.

Nail-care services are growing rapidly. If causes for the increase in nail-care service consumption is diversion or self-satisfaction, we can speculate that consumers perform self-care through nail-care services. Nail-care-service consumption should be allowed to increase because of the positive psychological effects such as improving mood or alleviating depressed emotions. Moreover, the psychological effects of nail-care services differ according to consumers’ tendencies. Therefore, this study divides the types of consumers, to investigate whether there is a difference in the psychological effects of nail-care services depending on the types. This study used the questionnaire survey method. Results of the study revealed that the sub-factors of self-esteem, extracted as two factors, were “personal self-esteem” and “social self-esteem”. Consumers were classified according to the sub-factors of self-esteem into four groups. There were differences in the psychological effects of nail-care services according to these four groups. It was found that all groups had psychological effects above the average value. This result indicates that only the degrees of psychological effects differ in accordance with the types of self-esteem, and that psychological effects generally play a large role in all types. Since psychological effects were positive for everyone regardless of their self-esteem, utilizing nail-care services considerably reduces the depression and anxiety of modern people. Nail-care services expected to become the basis of the nail therapy field.

An effective cleaning method for Ni removal in Ni-induced lateral crystallization(Ni-MILC) poly-Si TFTs and their electrical properties are investigated. The HCN cleaning method is effective for removal of Ni on the crystallized Si surface, while the nitric acid treatment results decrease by almost two orders of magnitude in the Ni concentration due to effective removal of diffused Ni mainly in the poly-Si grain boundary regions. Using the HCN cleaning method after the nitric acid treatment, re-adsorbed Ni on the Si surfaces is effectively removed by the formation of Ni-cyanide complexions. After the cleaning process, important electrical properties are improved, e.g., the leakage current density from 9.43 × 10−12 to 3.43 × 10−12 A and the subthreshold swing values from 1.37 to 0.67 mV/dec.

Surfactant-wrapped separation methods of metallic and semiconducting single-walled carbon nanotubes (SWCNTs) can result in large changes in intrinsic physical and chemical properties due to electronic interactions between a nanotube and a surfactant. Our approach to synthesize SWCNTs with an electronic feature relied on utilizing carbon nanorings, [n] cycloparaphenylenes ([n]CPPs), which are the fundamental unit of armchair type SWCNTs (a-SWCNTs) that possess a metallic feature without any surfactants. To obtain long tubular structures from [n]CPPs, the host-guest complexes formed with well-aligned [n]CPP hosts and various fullerene guests on a silicon substrate were pyrolyzed under an ethanol gas flow at a high temperature with focused-ultraviolet laser irradiation. The pyrolyzed [n]CPPs were observed to transform from nanorings to tubular structures with 1.5–1.7 nm diameters corresponding to the employed diameter of [n]CPPs. Our approach suggests that [n]CPPs are useful for structure-controlled synthesis of SWCNTs.

A simple, but effective means of tailoring the physical and chemical properties of carbon materials should be secured. In this sense, chemical doping by incorporating boron or nitrogen into carbon materials has been examined as a powerful tool which provides distinctive advantages over exohedral doping. In this paper, we review recent results pertaining methods by which to introduce boron atoms into the sp2 carbon lattice by means of high-temperature thermal diffusion, the properties induced by boron doping, and promising applications of this type of doping. We envisage that intrinsic boron doping will accelerate both scientific and industrial developments in the area of carbon science and technology in the future.
