Objectives: People with tension-type headache generally take pain relievers, but long term dependency causes problems as well as side effects. The present study aimed to provide clinical evidence of herbal medicine for tension-type headache by systematic review of randomized controlled trials on the effect of herbal medicine for tension-type headache. Methods: Randomized or quasi-randomized controlled trials that verified effects of herbal medicine intervention on patients with tension-type headache were included in the study. A literature search of English, Japanese, Chinese, Korean databases was performed. The selected literature were assessed by Jadad scale and Risk of Bias. Results: Herein, 40 reports were selected from a total of 157. Meta-analyses of 2 trials indicated that the effective rate was significantly higher in the herbal medicine treatment group, as compared to the placebo control (risk ratio: 1.49, 95% confidence interval (CI): 1.23 to 1.80, p<0.0001, I²=0%). Four trials that compared herbal medicine with routine care with routine care only group showed a significantly higher effective rate of benefits for herbal medicine with routine care, as compared to routine care only (RR: 1.57, 95% CI: 1.18 to 2.10, p=0.002, I²=0%). Conclusions: The effective rate was significantly higher than control and adverse events were less in the treatment group. Pattern analysis (辨證) indicated that the studies on wind-fire pattern (風火證) were highest. Yougeun-bang (柔筋方) in prescription and Paeoniae Radix Alba (白芍藥) in medicinal herbs were most used. This finding could be widely utilized in future clinical practice and form the basis for the development of clinical practice guidelines in advance.

Recently, attackers using malicious code in cyber security have been increased by attaching malicious code to a mail and inducing the user to execute it. Especially, it is dangerous because it is easy to execute by attaching a document type file. The author analysis is a research area that is being studied in NLP (Neutral Language Process) and text mining, and it studies methods of analyzing authors by analyzing text sentences, texts, and documents in a specific language. In case of attack mail, it is created by the attacker. Therefore, by analyzing the contents of the mail and the attached document file and identifying the corresponding author, it is possible to discover more distinctive features from the normal mail and improve the detection accuracy. In this pager, we proposed IADA2(Intelligent Attack mail Detection based on Authorship Analysis) model for attack mail detection. The feature vector that can classify and detect attack mail from the features used in the existing machine learning based spam detection model and the features used in the author analysis of the document and the IADA2 detection model. We have improved the detection models of attack mails by simply detecting term features and extracted features that reflect the sequence characteristics of words by applying n-grams. Result of experiment show that the proposed method improves performance according to feature combinations, feature selection techniques, and appropriate models.

Cyworld has created a new social phenomenon that relationship between people and communities could be built by committing to digital writing. It has altered the way of people's writing attitudes from self-confessed to self-describing and self-broadcasting ways in which one regards oneself as the center of the cyber world. The purpose of this paper is to identify the shift in one's writing attitudes and how he/she develops technologies of the self in the Cyworld space. Quantitative and qualitative methods support the result; The analysis of 100 Cyworld users' mini-homepages show how the visual images in Cyworld affects their way of digital writing and the analysis of the change of writing habit due to sharing data how virtual 'family' that has been created by Cyworld. I categorize the characteristics of digital writing into three; 1)Visualization of technologies of the self 2)Networked technologies of the self 3)Sharing secretes. The aim of writing in Cyworld is not to keep the secrete but to share and, eventually, texts are circulated in the networked society where one is participated(Cyworld family). Therefore, the usage of images plays a significant role in Cyworld communities because the opened secretes are usually prepared to be presented on the basis of trustworthy toward other members.

This study identified the substitution of /u/ for /o/ (e.g., pyəllo [pyəllu]) in Korean based on the speech corpus as a function of grammar items. Korean /o/ and /u/ share the vowel feature [+rounded], but are distinguished in terms of tongue height. However, researchers have reported that the merger of Korean /o/ and /u/ is in progress, making them indistinguishable. Thus, in this study, the frequency of the phonetic manifestation /u/ of the underlying form of /o/ for each grammar item was calculated in The Korean Corpus of Spontaneous Speech (Seoul Corpus 2015) which is a large corpus from a total of 40 speakers from Seoul or Gyeonggi-do. It was then confirmed that linking endings, particles, and adverbs ending with /o/ in the word-final position were substituted for /u/ approximately 50% of the stimuli, whereas, in nominal items, they were replaced at a frequency of less than 5%. The high rates of substitution were the special particle "-do[du]" (59.6%) and the linking ending "-go[gu]" (43.5%) among high-frequency items. Observing Korean pronunciation in real life provides deep insight into its theoretical implications in terms of speech recognition.

The purpose of this study was to verify the validity and reliability of the computerized general neurocognitive test using intuitive evaluation techniques to reflect the needs of the elderly and to validate neurocognitive function appropriately. The subjects were 100 elderly people who were over 60 healthy people. To evaluate the comprehensive neurocognitive function of the elderly, Computerized Neuro-cognitive Function Test (CNT, cybermedic. Co., Korea) developed by CyberMedic was used. The test consist of attention test, memory test and the problem solving ability test. As a result of correlation analysis of CNT test items, it was possible to confirm the characteristics of measuring single domain of attention and memory test. The problem-solving ability test also showed a high level of significant correlation, although the purpose of measurement was different, but a comprehensive cognitive function test for problem solving was possible. In the reliability analysis, the half reliability and internal consistency of test - retest were significantly higher. As a result of the above study, we conclude that the comprehensive neurocognitive test items constituted in this study have achieved reproducibility and effectiveness.

Tipping takes significant part in hospitality industry, especially in hotels and restaurants. According to the recent studies, over US$26.4B were given to the service personnel in the restaurant industry from the customers as tips in 2003 in the US alone. As a result of these developments, tipping has been a legitimate area of academic inquiry in many foreign countries but here in Korea this custom has not drawn much attention due to service charge being placed by the government since 1979. The purpose of this study is to analyse the perception and attitude of tip recipients and compare it with the results of previous studies carried out by Shamir and Parrett. Statistical analyses were carried out to compare the differences of perception between tip recipients and non recipients on the staff role conflict, job satisfaction, pay satisfaction and attitude toward the guests. It is suggested from the finding that the current service charge system needs to be taken into consideration for possible revision or alteration as the management environment and customer needs in the hospitality industry in Korea are changing at an enormous pace. As this study focused on the perception of employees, further study on the perception of customers to tipping is highly recommended.

Application field of third dimension graphic is becoming diversification by the fast development of hardware recently. Various theory of details technology necessary to design game such as 3D MMORPG (Massive Multi-play Online Role Flaying Game) that do with third dimension. Cyber city should be absorbed. It is the detection speed that this treatise is necessary in game engine design. 3D MMORPG game engine has much factor that influence to speed as well as rendering processing because it express huge third dimension city´s grate many building and individual fast effectively by real time. This treatise nay get concept about the collision in 3D MMORPG and detection speed elevation of game engine through improved detection method. Space division is need to process fast dynamically wide outside that is 3D MMORPG´s main detection target. 3D is constructed with tree construct individual that need collision using processing geometry dataset that is given through new graph. We may search individual that need in collision detection and improve the collision detection speed as using hierarchical bounding box that use it with detection volume. Octree that will use by division octree is used mainly to express rightly static object but this paper use limited OSP by limited space division structure to use this in dynamic environment. Limited OSP space use limited space with method that divide square to classify typically complicated 3D space´s object. Through this detection, this paper propose follow contents, first, this detection may judge collision detection at early time without doing all polygon´s collision examination. Second, this paper may improve detection efficiency of game engine through and then reduce detection time because detection time of bounding box´s collision detection.

The purpose of this study is to define the relationship between ethical management, organizational culture, and management performance in long-term care institutes for the elderly while identifying the level of ethical management, organizational culture, and management performance of caregivers and the impact and mediation of the relationships between them based on the hypothesis. The results show that caregivers in the Gyeonggi region scored 2.929 out of 5 in ethical management, 3.393 in organizational culture, 2.925 in organizational transparency and 3.185 in management performance. The levels of ethical management, organizational culture and management performance in caregivers are lower than those of welfare workers, social workers, and nursing assistants. This is due to their relatively low level of education, wages and working environment. This study determined that there is a significant relationship between variables in terms of correlation between ethical management, management performance, organization transparency, and organizational culture. Second, the authors adopted hypotheses that ethical management has a statistical effect on organizational transparency, management performance, and organization culture. Third, the authors concluded that organizational culture has a direct impact on organization transparency and there is a significant mediation effect between ethical management, organizational transparency, and management performance. Based on these results, we propose the following: First, ethical leadership at the core of ethical management. Second, awareness in organizational transparency. Third, balanced management performance. Fourth, a flexible organizational culture that can respond to ethical management environment must be established.

The purpose of this study was to identify characteristics related to self assertiveness in teenage girls, and to identify the relationship between the self assertiveness and sexual experiences in teenage girls in Korea. The subjects for this study were 12,733 girls from an accessible population of 19,000 girls who were a multi-stage cluster sample from a population of 1,988,902 girls attending to 4,684 schools in the seven large cities and nine provinces of Korea. The response rate was 68.9%. Data were collected by mail from October 2 to October 28, 2000. A structured questionnaire of 125 items which included measurement of general characteristics, sexual experiences, and self-assertiveness was used. The sexual experiences were defined as dating, holding hands, putting arms on the shoulders, light kissing, French kissing, touching breasts, touching genitalia, and coitus. The self assertiveness measurement was developed by S. B. Chang et al.(2000) and has a Cronbach's alpha of .6031. Data was analyzed with SPSS 10.0 Program using descriptive statistics, reliability, and t-test. The results of this study are as follows; 1. The subjects were from 9th to 11th graders and 42.7% answered that they followed their partner's request. The range for the self assertiveness score was 7-21 out of a possible range of 7-21. The group of girls who were in vocational schools, lived away from family or in rural areas, attended night school, took part in drinking, smoking, and glue inhalation, who had cyber sex or phone sex or were exposed to pornography, and who had run away from home showed significantly lower self assertiveness scores than those without these characteristics (P<.05). 2. The group which had experience in dating(t=2.379, P=.017), French kissing (t=5.425, P=.000), touching breasts (t=8.637, P=.000), touching genitalia (t=6.057, P=.000), and coitus(t=6.057, P=.000) showed significantly lower self assertiveness scores than the group which had not had these sexual experiences. But there was no difference in the self assertiveness scores between the group which had experience of holding hands, light kissing, and using contraceptives compared to the group which did not. It can be concluded that the group which had delinquent behavior showed lower self assertiveness, and the lower self assertiveness led to unwanted sexual experiences. It is suggested that self assertiveness training be provided for the group with delinquent behavior as a first priority, and then analyze of the process of self assertiveness in relation to sexual experiences.
