Objective: To date, only a few studies have investigated the relationships between genetic polymorphisms and external apical root resorption (EARR). Hence, the aim of this systematic review was to explore the relationship between different gene polymorphisms and their association with EARR. Methods: A complete literature search was conducted by two independent reviewers. The PubMed, Science Direct, and Scopus databases were searched. In addition, the bibliographies of all textbooks and relevant articles were searched manually. A meta-analysis was performed using data entered into the electronic databases until February 28, 2017. Results: On the basis of the search, we identified 17 and 7 publications for the systematic review and meta-analysis, respectively. Odds ratio (OR) was used to evaluate the association of the interleukin 1B (+3954) polymorphism and the risk of EARR. The overall OR from the studies was used to estimate the risk of EARR. However, no association was found and no publication bias was apparent for the risk of EARR in patients receiving orthodontic treatment. Conclusions: More research on the relationship between gene polymorphism and EARR is necessary to determine better specificity of possible interactions.

Pogostemonis and Agastachis Herba are the whole of Pogostemon cablin (BLANCO) BENTH or Agastache rugosa (FISCHER et MEYER) O. KUNTZE (family Labiatae) which is produced in all part of Korea and China. This drug is used for removing dampness by means of aromatics in oriental medicine. The standard formula of this drug is important from the viewpoint of the quality control. A characteristic discrimination of internal and external morphological standard in original plants and herbal states of Pogostemonis and Agastachis Herba are as follows. 1. The external characteristics: Pogostemon cablin has hairs and brown-like in stem, elliptical fruit. In the other hand, Agastache rugosa has no hairs and red-like in stem, obovatic trigone fruit. 2. The physical characteristics: Pogostemon cablin is gray in whole, has hairs in stem and numerous hairs of ash in leaf. In the other hand, Agastache rugosa is yellow-green in whole, has no hairs in stem. Specially the latter has deep-green colour and numerous hairs presenting mostly at lower epidermis in leaf. 3. The physical characteristics in currents: Pogostemon cablin is brown, has hairs and round-like stem. In the other hand, Agastache rugosa is green or yellow-green, has no hairs and tetragon in stem. 4. The internal characteristics: Pogostemon cablin has progressed spongy tissue in epidermal cell of leaf and many rank of epidermal cell in stem. In other hand, Agastache rugosa has 1 rank palisade tissue in leaf and few rank of epidermal cell in stem. In the external shape, it was possible that herbs were distinguished according to artificial classification and that same genus-degree of relatedness among herbs could be distinguished by more precise and active observation. In the shape of real herbs, I compared current herbs in market with original herbs which were just collected or were on the course of drying. In addition, it was possible that the internal shape could be identified by using microscope after butanol series. Though it was impossible to make distinction of herbs which are not current in my search contents, this search contents will be a standard for applying herbs in the future. An Additional standard establishment including physiochemical reaction and gene research is required in order to supplement the fault of this search.

This paper mainly presents a secure and efficient e-Medical Record System via searchable encryption scheme from asymmetric pairings, which could provide privacy data search and encrypt function for patients and doctors in public platform. The core technique of this system is an extension public key encryption system with keyword search, which the server could test whether or not the files stored in platform contain the keyword without leaking the information about the encrypted file. Compared with former e-medical record systems, the system proposed here has several superior features: (1)Users could search the data stored in cloud server contains some keywords without leaking anything about the origin data. (2) We apply asymmetric pairings to achieve shorter key size scheme in the standard model, and adopt the dual system encryption technique to reduce the scheme's secure problem to the hard Symmetric External Diffie-Hellman assumption, which could against the variety of attacks in the future complex network environment. (3) In the last of paper, we analyze the scheme's efficiency and point out that our scheme is more efficient and secure than some other classical searchable encryption models.

This study proposes a multi-robot system, using multiple autonomous robots, to explore concrete structures and assist in their maintenance by sealing any cracks present in the structure. The proposed system employed a new self-localization method that is essential for autonomous robots, along with a visualization system to recognize the external environment and to detect and explore cracks efficiently. Moreover, more efficient crack search in an unknown environment became possible by arranging the robots into search areas divided depending on the surrounding situations. Operations with increased efficiency were also realized by overcoming the disadvantages of the infeasible logical behavioral model design with only six basic behavioral strategies based on distributed control-one of the methods to control swarm robots. Finally, this study investigated the efficiency of the proposed multi-robot system via basic sensor testing and simulation.

Objectives : We conducted a literature search to identify trends with respect to miniscalpel acupuncture points (MAPs) of the cervical region with the aim of providing guidance regarding miniscalpel acupuncture (MA) in the cervical region. Methods : We searched 2 overseas sites (PubMed and Google Scholar) and 5 domestic sites (NDSL, RISS, KISS, OASIS and Korean Traditional Knowledge Portal) for clinical trials of MA of the cervical region. The search terms used were "acupotomy or miniscalpel acupuncture or miniscalpel" and "cervical." Of 73 studies found, 11 were included in this review, 6 of which presented exact MAPs. Owing to the lack of data, we refer to 1 Korean and 4 Chinese articles to analyze the exact location and meaning of the MAPs used in the published studies and to propose other clinically applicable MAPs. Results : We identified 10 of the most commonly used MAPs in the published studies, including those located below the external occipital protuberance, 2-2.5 cm both side down of the external occipital protuberance, 4.5-5 cm both side down of the external occipital protuberance and C3-7 spinous process. Furthermore, we proposed 13 additional MAPs that can be used clinically. Conclusion : We hope that this study will form a basis for the development of MA and hope to improve the safety and reproducibility in future MA studies of the cervical region.

The purpose of this study is to identify the relationship among injury prevention practices, health locus of control, and response patterns to HLOC of the elderly. Subjects were 121 healthy elderly. The data had been collected from November 5 to 18 in 2001 and analyzed with descriptive statistics, t-test, ANOVA, Pearson's correlation and stepwise multiple regression. Health locus of control and injury prevention practices were measured by using MHLC scale and an instrument created by the researcher on the basis of the results of literature review respectively. The results of this study were as follows: The mean score of injury prevention practices was 2.80 and the mean scores for the health locus of control were internal health locus of control : 17.25, external health locus of control : 16.09, and chance health locus of control : 14.26. The response patterns of the HLOC identified were six types; pure internal, pure powerful others, pure chance, double external, believers in control, and complex control. The 'pure internal' was the largest group(35.5%), and the 'believers in control' was the next(31.4%). The relationship between internal health locus of control and the injury prevention practices of the elderly revealed a significant correlation(r=.215, p=.018). The relationship between external health locus of control and the injury prevention practices of the elderly revealed a significant correlation (r= .208, p=.022). There was significant difference between response patterns of the health locus of control and injury prevention practices(F=2.393, p=.042). There were significant differences between injury prevention practices and general characteristic factors, which were education, family type, administration of medication, injury experience, ADL, and self-directed search for health information. Self-directed search for health information, injury experience, and education explained 16.7% of the variance for injury prevention practices. The above results may be used as the basic data for seeking more efficient way of improving safety of the elderly.

Objective : The aim of this study was to search and analyze the herbal combinations in formulas used to treat atopic dermatitis in Korean medicine. Methods : Articles on the atopy were searched for from among those registered on the OASIS up to December, 2015. After the articles were reviewed, information on both internal and external formulas for atopy was constructed. Then, the herbal combination in the formulas was analyzed by using frequency distribution, network analysis, and data mining. Results : The combination of 'Saposhnikovia Radix - Schizonepetae Spica' and 'Scutellariae Radix - Phellodendri Cortex ' was mostly used in both internal and external formulas to treat atopy in articles. By using the network analysis and data mining, twelve combinations including ' (Saposhnikovia Radix, Ponciri Fructus Pericarpium) - (Platycodi Radix, Schizonepetae Spica) ' were discovered. Five effective combinations were also searched for external formulas.Conclusions : This study could help researchers to analyze the formulas in various ways. Moreover, the herbal combination in atopy formulas could be used to search for atopy formulas in other databases or make a new prescription.

The purpose of this research is to investigate the effects of the product display type on the consumers' purchase intention, attitude toward store, and revisit intention in the various mobile shopping situations. To test the hypothesis, between-subjects experiment with 3 mobile shopping situations (outdoor place, public transportation, commercial facilities) by 3 product display types (search, category, product) was conducted, and analyzed with ANCOVA (analysis of covariance). The result of the experiment shows there are no main effects of the mobile shopping situations and the product display types, but the interaction effects of the product display type and the mobile shopping situation on the purchase intention and the revisit intention are statistically significant. However the attitude toward the store is not affected by the treatments. Experiment results suggest that the positive consumer responses in terms of the purchase and revisit intention can be achieved when the product display is matched with the situation in the mobile shopping setting. Controlling consumers' evaluation on the product information and their experience of online shopping, we can take these effect as the results of match-up between the product display type and the situational factors surrounding mobile shopping. The result provides strong support for the location-based service in mobile shopping. Most of the mobile device can utilize the consumers' location which can be easily interpreted as the situational factors. With regard of the level of the external stimulation, the shopping service providers can offer the main interface with the right match with the consumers' situations. When the external stimulation level is high, they should provide the category display or product display in the target promotion in their mobile shopping apps. However if the target is on the way with the low external stimulation level, they should provide the search format as the main interface in their apps. More interestingly, this kind of manipulation does not affect the consumers' attitude toward the store according to our research result. Future research direction is discussed.

검색가능 암호시스템(searchable encryption system)은 암호화된 자료의 기밀성이 보장된 상태로 원하는 자료의 검색을 가능하게 해주는 기술이다. 클라우드 서비스의 대중화로 데이터 아웃소싱에 대한 관심이 높아지면서 외부 서버의 신뢰 문제를 해결하는 방법으로 최근에 많은 연구가 진행되고 있다. 하지만 대부분의 검색가능 암호시스템에 대한 연구는 하나의 키워드를 이용한 부울 검색만 제안되었고, 다중 키워드 검색에 대한 연구결과는 상대적으로 적을 뿐만 아니라 이 연구들은 대부분 고정 필드 환경을 가정하는 제한적 기법들이다. 이 논문에서는 고정 필드를 사용하지 않으며, 랭킹 정보까지 제공할 수 있는 새로운 다중 키워드 검색가능 암호시스템을 제안한다. 이 시스템은 키워드와 소수를 매핑한 소수테이블과 검색 연산으로 최대공약수 연산을 사용하기 때문에 기존 시스템보다 상대적으로 효율적이며, 복잡한 암호모듈이 필요 없어 비교적 쉽게 구현이 가능하다.
