This is written to present basic shot information among iron clubs and information of weight shift, because previous study conducted on all clubs was rut enough. This article is about shot analysis of iron club 3,4,5,6,7,8,9 and weight movement, conducted on four skilled golf players and four students who major in golf and are less than three years. The analysis of long and short irons showed statistically meaningful different results for all the participants but iron clubs of 3,4,5 didn't in head speed and ball speed. The skilled group showed better results in head speed, ball speed and direction, Launch angle than the unskilled group. In weight shift movement analysis, the unskilled group moved, on back swing top, their more weight(65.36%) but the skilled group was on their left foot (70.21%)when clubs were on impact moment. It shows that the skilled group put on power more efficiently by moving weight.

A node of mobile IPv6 moving foreign networks needs authentication process to support right services against from security threat. AAA is a trust infrastructure that authenticates, authorizes, and accounts nodes receiving a network service. And Mobile IPv6 Working Group recommends use of AAA infrastructure to authenticate mobile nodes. Event though AAA infrastructure provides strong authentication functions, it should exchange a lot of messages to authenticate mobile nodes every movement. The exchange of lots of messages causes latency and it is interfered with realization of real-time communication. This paper proposes an authentication method of improved speed using hash value of mobile node to reduce authentication latency. Directly after movement, a mobile node applying a Proposed method uses extended existing security authentication for a while and deletes the establishment latency of new security authentication. Performance evaluation of a proposed method verifies the efficiency through the analysis of cost comparison with other methods. The conclusion of performance evaluation is that the proposed method gets more 25% performance improvement than a general method when a mobile node moves another subnet.

In a graph G=(V, E) with n vertices, there is an unique box which is finally laid on each vertex. Thus each vertex and box is both numbered from 1 to n and the box i should be laid on the vertex i. But, the box ${\pi}$(i) is initially located on the vertex i according to a permutation ${\pi}$. In each step, the robot can walk along an edge of G and can carry at most one box at a time. Also when arriving at a vertex, the robot can swap the box placed there with the box it is carrying. The problem is to minimize the total step so that every vertex has its own box, that is, the shuffled boxes are sorted. In this paper, we shall find an upper bound of the minimum number of steps and show that the movement of the robot is found in $O(n^2)$ time when G is a cycle.

Objective : The purpose of this study was to examine foreign literature on the evaluation and interventions for motor functions in children. Methods : Studies in this review were identified by searching the PubMed, Cochrane Library (Embase) databases from those published form January 2010 to March 2020 using the following keywords: "motor function test" or "motor function measure" or "movement assessment" or "motor proficiency test" or "motor scale" or "motor skill" and children. Results : Of the total 37 identified studies, 14 analyzed evaluations, 23 analyzed interventions, all of which were randomized control trials. Studies on evaluations were increasingly more common, in contrast to studies on interventions for motor functions. The most frequent field of research was rehabilitation. The studies on evaluations included the AIMS and MABC-II, and GMFM was the most frequently used intervention. Interventions were most commonly used in task-oriented training (six studies). Conclusion : This study aimed to provide a basis for therapists to choose effective motor function evaluation and interventions for clinical trials by analyzing studies related to interventions for and evaluation of motor function in children.

Purpose: This study summarized architectural planning data for clinical practice spaces for CPX/OSCE and Simulation spaces, through analysis of domestic and foreign literature and a survey of domestic colleges of medicine. Methods: This study analyzed the architectural planning elements of the clinical practice spaces of the college of medicine, through a literature review on the clinical practice space and the survey of four recently established colleges of medicine. Results: ① It is desirable to plan the floor plan type for Simulation and CPX/OSCE spaces as a corridor-separated type that separates the circulations between students and staff (faculty). ② The simulation area arranges their practice rooms around the control space where the circulation of the staff is made. Conversely, it is desirable to arrange the CPX/OSCE rooms around the test waiting room where students enter. ③ It is desirable to separate access to the staff and students to allow student control, and to install various support spaces facing the staff corridor to secure the movement of equipment and the flow of evaluators. ④ In the simulation area, the equipment stored in the storage must be set in each room before the practice according to the setting of delivery or surgery like, and the equipment that has been removed must be back, so the circulation is short and does not intersect with the student circulations. ⑤ Debriefing rooms, seminar rooms, etc. are arranged in the staff area for review and discussion of clinical situations where practice and evaluation have been completed. Implications: It is important to configure an appropriate movement system and spatial zoning for each space for simulation and CPX/OSCE.

This study was to investigate the elasticity in tourism demand of Chinese tourists visiting Malaysia through ARDL models by using Chinese tourists arrivals, GDP, CPI, transportation costs and others. When China was implementing an open-door policy with foreign countries in the early 15th century, the movement of Chinese was very limited, and then communication between China and other countries was very weak. However, the Chinese government persistently and entirely implemented an open-door policy by participating in the World Trade Organization(WTO) in 2001. The Chinese government has opened the economy through foreign direct investment by providing various incentives for foreign investment. As a result, inbound and outbound Chinese movements increased in the early 21st century. China was one of the top five most visited tourist destinations in the world by 2016, and also Chinese tourists traveling abroad increased, so they made Malaysia a popular tourists destination because of increase sharply to around 1.41 million. This study examined the significance of major economic factors affecting the increase in Chinese tourists arriving in Malaysia. Other factors that induced their arrival included income, tourism prices, transportation costs and promotional activities. Short-run shocks from the Asian economic crisis and the outbreak of SARS were included to understand how tourism demand in Malaysia was affected. Finally this study found that the combination of the ARDL and the Error Correction Model were useful to statistically estimate the elasticities of tourism demand.

The purpose of this study was to look into Korean film criticism that started during Japanese occupation. It's specifically attempted to shed light on the development and significance of Joseon film criticism and on film movement theory as part of the history of Korean early modern film criticism. When kino-drama that could be called the start of Joseon movies was popular, enlightenment-based view of movie was rampant due to the inflow of western civilization and modernistic consciousness. Afterwards, the nature of movie itself drew a lot of attention from contemporary people in the silent picture days, and there appeared a critical trend in pursuit of artistry. Diverse criteria of criticism about reality and representation were presented, and a lot of disputes were eventually stirred up. Thus, criticism started to make a progress. A proletarian film movement theory, the so-called KAPF film campaign that was prevalent from the mid-1920s to the mid-1930s, was one of leading contemporary movie theories and took the lead in critic community. That had a great impact on the entire Joseon film circles. That took a proletarian view of movie, which was based on Bolshevik theory of Popularization and dialectic historical materialism. their criticism made a contribution to providing information on foreign movies and theories and to presenting main principles and multiple alternatives toward film organization and playing.

Tic disorder is a childhood neuropsychological disorder characterized by abrupt, involuntary, and repetitive stereotyped muscle movement or vocal sound. Tourette's disorder shows a chronic prognosis, and can last for life if no treatment is applied. Although tic disorder has been known for ages, the underlying cause is still not well known. Non-pharmacological treatments have long been used for the tic disorder, but few clinical studies were conducted. However, the European Society for the Study of Tourette's Syndrome recently issued non-pharmacologic guidelines for treatment of tic disorders based on the research findings obtained so far. In addition, guidelines for non-pharmacologic evidence-based treatment were reported in Canada, North America. By synthesizing the newly reported foreign guidelines for treatment and review articles, the aim of this study is to investigate the non-pharmacologic therapies used for treatment of tic disorder or Tourette's disorder.

Styloid process is a slender pointed bone of variable length, which project downward, forward, and slightly medialward from the posteroinferior portion of the tympanic part of the temporal bone. Embryologically, the styloid process is derived from Reichert's cartilage, a structure of second branchial arch origin. Most patients with elongated styloid process remain asymptomatic, but some patients complain pain and sensation of foreign body in the throat, dysphagia, dysphonia, referred otalgia. Recently, we have experienced a case of elongated styloid process in a fifty-nine year old man. He had been suffered from Rt. side sore throat, headache and pharyngeal discomfort during head movement. Through various X-ray examination, Xeroradiography, and palpation of tonsillar fossa, elongated styloid process on Rt. side was confirmed. Under the general anesthesia, it was successfully removed out via transoral approach technique, described by Eagle. The resected styloid process was 2.5cm in it's length and he was freed from the symptoms without further complication.
