Acceptance and Commitment Therapy (ACT) is a functional contextual intervention approach based on the behavioral theory on human language, which views human suffering as originating in psychological inflexibility fostered by cognitive fusion and experiential avoidance. Thus, the goal of ACT is to enhance psychological flexibility using six core processes including acceptance, cognitive defusion, self-as-context, contact with present moment, values clarification, and committed action. Recent clinical trials have suggested the efficacy for ACT in the treatment of various mental illness and psychological distress. The aim of this review is to offer more knowledge and better understanding of ACT by presenting its underlying principle and an overview of the research field.

Purpose: In the present study, the actual management state of trial contact lenses and lens care products in local optical shops was surveyed and analyzed to reduce the risk of lens complication possibly induced by neglecting lens care. Methods: The feeling of contact lens wearers during the wear of trial contact lenses was surveyed. Futhermore, the actual management state of trial contact lenses such as cosmetic lens and RGP lens and lens care products was also investigated by surveying opticians who trade contact lenses in local optical shops. Results: It was found that consumers trusted the sanitary conditions of the lens since trial cosmetic contact lens and RGP lens were cleaned before and after trails by over 98% of opticians in local optical shops. For trial cosmetic lens, cleaning with normal saline, multipurpose solution for soft lens and combination of saline and multipurpose solution were 38.5%, 40.5% and 21%, respectively, before trials. After trials, cosmetic lenses were cleaned with normal saline, multipurpose solution for soft lens and a combination of saline and multipurpose solution were 13%, 75%, and 12%, respectively. On the other hand, cleaning with normal saline, multipurpose solution for RGP lens and combination of saline and multipurpose solution were 28.5%, 38.5% and 33%, respectively, before trying trial RGP lens. After trials, RGP lenses were cleaned with normal saline, multipurpose solution for RGP lens and a combination of saline and multipurpose solution were 2.5%, 70%, and 27.5%, respectively, indicating that relatively many opticians followed the lens cleaning regimen. In local optical shops, the cleaning trial cosmetic lens was mainly conducted at every 10 days or a month and the washing cycle of cosmetic lens case was in a month or 2~3 months. The cleaning interval of trial RGP lens was primarily in a month or 2~3 months. For those lens cases, more than 75% of opticians washed them with a surfactant and then rinsed with cold water. The storing periods of lens care products were primarily in a week for saline and in a month and 2~3 months indicating that storing period of lens care products was relatively well-kept in local optical shops. Conclusions: It is thought that the concern about any microbial infection is not that high since trial contact lenses and lens care products were generally well-managed by opticians in local optical shops from the results above. However, better public eye health and better public confidence in opticians may be possible if further strengthen in avoidance of lens cleaning with saline, keep of cleaning cycles within 2 weeks and rinsing of lens cases with hot water happens.

We're living in a world of one global village. The globalization of business is acceleration as more companies cross national borders to find customers, materials and money. Many foreign companies and organizations are doing their business aggressively in Korea and many Korean companies and rushing into foreign market. When people communicate for business with someone from another culture, there could be difficult communication barriers to overcome resulting from differences in their values, beliefs, norms for behavior, expectations, attitudes and so on. To do successfully business, we need to understand culture background and communication style that is different from nation, race, language. Communication barriers stemming from cultural differences may vary. Largely, they can be divided into value system, non-verbal communication, and perception process. Value system can be divided into individualism versus group orientation, avoidance of uncertainty degree, power distance, and high- context culture versus low-context culture. Also non-verbal communication method and perception process may play decisive roles in communication effectiveness. Especially nonverbal communication barriers which sometimes play more important roles than the verbal parts are composed of eye contact, gesture, kinesics, proxemics, chronemics, paralanguage and language of color Cross-cultural communication affect business situation. I expect that if we understand cultural background, and then we overcome cross-cultural communication barriers. To overcome and to adapt inter-cultural business, we need to develope curriculum on the cross-cultural education which I will study in the next paper.

In client-solver environments, clients can execute applications without contact a server by storing data in its cache. To guarantee correction of applications, we need a cache consistency algorithm. Many cache consistency algorithms have been proposed, these were categorized by detection-based and avoidance-based algorithms. In this paper, we propose a new detection-based cache consistency algorithm that can reduce a burden of a client that has poor resource compare with a server Our method controls concurrency of transactions using timestamp ordering and updates a cache dynamically. In addition to we show that our method maintains a one-copy serializability.

Rollover accident is one of the serious traffic accident and rollover accident takes high portion of all accident. The most common type of rollover is a tripped rollover which occupy 95% of all type of single-vehicle rollover. Tripped rollover occurs when a vehicle leaves normal road way and tripped by loose gravel, soil of fixed object such as guard rail, curbs and ditches. And the rest of the type of rollover is un-tripped rollover. An un-tripped rollovers that occurs during high-speed collision avoidance maneuvers. In this paper, presents the explanation of the un-tripped rollover test method and procedure, additionally this paper deals with various occurrence in the un-tripped test such as occurring excessive tire camber in the un-tripped test, tire side-wall contact with road surface and roll oscillation. And this paper analyzes the analysis of the roll rate amplitude in specific frequency through the FFT (Fast Fourier Transform) and the roll angle at the steering reverse timing which is the Fishhook test roll rate feedback time. Finally, this paper analyzes the relations between the estimated steady state roll gain and rollover stability.

5-axis NC machining has a good advantage of the accessibility of tool motion by adding two rotary axes. It offers numerous advantages such as expanding machining fields in parts of turbo machineries like impeller, propeller, turbine blade and rotor, reasonable tool employment and great reduction of the set-up process. However, as adding two rotary axes, it is difficult to choose suitable machining conditions in terms of cutter path and cutter posture at a cutter contact point. Therefore in this paper, it is proposed to decide suitable machining condition through an experimental method such as adopting various cutter paths, cutter postures types. Also, in order to increase the efficiency of 5-axis machining, it is necessary to minimize the cutter posture changes and create a continuous cutter path while avoiding interference. This study, by using an MC-space algorithm for interference avoidance and an MB-spline algorithm for continuous control, is intended to create a 5-axis machining cutter path with excellent surface quality and economic feasibility. finally, this study will verify the effectiveness of the suggested method through verification processing.

The avoidance of the allergen of the house dust mite is one of the challenges to reduce and treat the symptoms of allergic diseases. Accordingly, various acaricidal agents are being used to kill the mite, but just killing it leaves the remains of it, which still act as the allergen. Therefore expelling the mite is thought as best policy to avoid the mite allergen. For this, some materials have been applied to repellent agents against the mite. Among them, a material with natural origin, known as the phytoncide, is being used for its repellent activity, as well as for its benefits for health. In this experiment, essential oils extracted from Korean white pine (Pinus koreaiensis S. et Z.) and hinoki cypress (Chamaecyparis obtusa), which are widely used as the source of phytoncide products, are studied for demonstration of the repellent effect against the house dust mites, Dermatophagoides farinae and D. pteronyssinus. Direct contact method was used to evaluate the repellent effect (%). And the results suggest the oils have a significant effect enough to be used as a source of repellent agent. For the repellent effect, the most effective concentration was $0.5{\mu}l/cm^2$ at 45 minutes both in the white pine and the hinoki oil.

Aids to Navigation is one of the most important facility for safety at sea. However, in terms of position there always exists discrepancy in inventory by media and/or organizational body who maintains the facility which may result in incredibility for navigator's position fixing or hazard avoidance. This paper suggests two major factors as the causes of the position error when they design, install and survey the aids to navigation. One is the function of direction of tide and water depth which makes swinging circle. The other is a variable value by time resulting from multiple coordination of satellites in contact. This paper aims to minimize inaccuracy by verifying its reason through numerical analysis over inherent position error.

This research aims to identify the relationship between visual perception and emotion by the types of fear responses elicited from warning images on cigarette packages as well as the effectiveness of the size of such images through questionnaires and eye-tracking experiments with twenty university students from the colleges based in Busan. The research distinguished and analyzed the warning images as rational appeals and emotional appeals by the degree of fear and disgust and the result concurred with the research conclusions of Maynard that people would naturally avoid eye contact when presented with a warning image on cigarette packages. Also, eye avoidance was highly identified with larger (75%) warning images. While the previous research mostly adopted the self-rated validation method, this research tried to make the methodology more objective by adopting both questionnaires and eye-tracking experiments. Through this research, authors contribute to finding effective warning images on cigarette packages in a way to increase public awareness of the dangers of smoking and discourage smoking. Further research is recommended to explore the effectiveness of using explicit images on cigarette packages by the types of smokers such as heavy smokers, normal smokers, and non-smokers.

Purpose: Purpose: The purpose of this study was to provide basic data to develop sexual abuse prevention educational programs for elementary school students. Method: Ninety three third, fourth, fifth, and sixth grade elementary school students were interviewed for content analysis on sexual abuse. Results: The content recognized by elementary school students about sexual abuse was as follows: 1) The concepts of sexual abuse were 'compulsory contact', 'harassment', 'school violence', 'pornography', 'unpleasant sexual behavior' 'crime', and 'don't know'. 2) The causes of sexual abuse were 'intolerance of impulse', 'play', 'bullying', 'financial needs', 'home education and the environment', 'negligence of the victim', and 'don't know'. 3) The methods how to prevent and deal with sexual abuse were 'sexual education', 'avoidance of danger', 'protection', 'self-assertion', 'treat with kindness', 'strengthening of penalties', 'asking for help and notification', 'report', 'treatment and counselling', 'escaping', and 'don't know' 4) Educational needs for prevention of sexual abuse were 'more detailed sexual abuse prevention education', 'how to recognize sexual abuse', 'how to protect oneself', 'interpersonal relationship', 'practical education', and 'none'. Conclusion: These results suggest that based on elementary school students' recognition of sexual abuse, a sexual abuse prevention educational program and content should be organized.
