A conservative treatment approach to temporomandibular disorder (TMD) is recommended as the first line of management, usually with a stabilization splint. Recently, computer-aided design/computer-aided manufacturing and three-dimensional printer has been widely used in the dentistry since several years ago. The authors apply digital dentistry in oral medicine fields to make stabilization splint for TMD treatment.

The selection of keywords for bidding is a critical component of paid search advertising. When the number of possible keywords is enormous, it becomes difficult to choose the best keywords for advertising and then subsequently to assess their effect. To this end, we propose an ultrahigh dimensional keyword selection approach that not only reduces the dimension for selections, but also generates the top listed keywords for profits. An empirical analysis using a unique panel dataset from a large online clothes retailer that advertises on the largest search engine in China (i.e., Baidu) is presented to illustrate the usefulness of our approach.

Although the information related to health and nutrition continues to increase at an ever-increasing rate, systematic database which is necessary for self-management of woman health over the life cycle has been rarely found. The purpose of this study was to offer valuable information on woman health and nutrition through the computer, and, therefore, to enable Korean women to manage their health by themselves according to their life cycle, Prior to constructing the information system, a survey was conducted to verify the use and usefulness of the health information currently available through the PC communication and internet, and to identify the specific topics of the health and nutrition information Korean women need. A self-administered questionnaire was distributed through PC communication. The responses of 1,117 women were analyzed. Most of the subjects(72.8%) were at the age of twenties, and 14.6% at tens, 10.7% at thirties, and only 1.9% were over forties. The educational level of the subjects was high ; 44.8% were college graduates or above, 31.4% were college students. The greatest obstacles to the use of health information appeared to be the lack of expertise of the information on the PC communication and taking too much time to get information on the internet. The extent of the interest of the specific topic was determined by a 5-point scale. Out of the 22 topics of the health and nutrition information given on the questionnaire, stress management was ranked as the top over the whole range of age. The top three topics in which women had interests except stress management varied by age group ; diet for weight control and self-evaluation of the meal at the age of less than twenty-four ; health and nutrition management for preventing cancer and diet for weight control at the age of twenty-five to twenty-nine ; health and nutrition management for infants and children, and for preventing osteoporosis at the age of thirty to thirty-four ; health and nutrition management for preventing osteoporosis, and for preventing cancer at the age of over thirty-five. On the basis of these results an information system necessary to Korean women in order to manage their health by themselves according to the life cycle will be constructed through internet.

지식은 21세기 기업 경영에서 생산성을 향상 시키는 가장 중요한 자산이다. 기업들은 오늘날 급변하는 경영환경에서 지속가능한 경쟁력 확보 및 조직 내 효율적 지식관리를 위해 지식경영을 적극적으로 도입하고 있다. 이러한 지식경영은 기업의 선택이 아닌 필수사항이 되고 있다. 현재 지식경영시스템을 도입하고 있는 많은 기업들은 IT와 관련된 하드웨어적 인프라는 어느 정도 구축하고 있지만, 지식경영을 위한 문화는 아직 만들어 내지 못하고 있다. 따라서 기업들이 지식경영을 도입하기 위해 많은 시간과 비용이 사용하였지만 그 성과는 기대만치 달성하지 못하고 있다. 이러한 문제점을 해결하기 위해서는 단순히 지식경영의 기반강화를 지원하는 하드웨어 중심의 지식경영 전략 보다는 지식경영문화를 강화할 수 있는 교육, 네트웍 연계 등 소프트웨어적 중심의 지식경영 전략이 필요하다. 본 연구에서 제시한 지식경영프레임워크는 비록 탐색적인 수준이지만 본 연구는 성공적인 지식경영의 도입을 위해 기업들이 중요하게 고려해야 할 요인들을 구분하는데 노력하였다.

IPTV(Internet Protocol Television)기술은 통신과 방송의 새로운 융합 기술로 다양한 양방향 TV 서비스를 제공한다. 이러한 서비스를 제공받기 위해서는 TV에 연결된 셋톱박스 (STB, Set-Top Box)와 정당한 가입자의 스마트카드 간의 상호 인증이 이루어져야 한다. 본 논문에서는 한 조직 내에서 직위나 부서 등과 같은 특성(속성) 값들에 따라, IPTV 서비스를 이용할 수 있도록 하는 속성기반 인증 기법을 제안하고, 제안하는 기법이 안전함을 보인다. 제안하는 기법에서 사용자는 자신의 아이디, 패스워드와 스마트카드를 이용하여 인증 메시지를 생성하는데, 이 때 자신에게 속한 다양한 속성을 이용할 수 있기 때문에 가입자는 한 번의 등록으로 속성에 따라 다양한 서비스를 제공받을 수 있다는 장점이 있다. 우리가 아는 한도 내에서는, 본 논문에서 제안하는 기법이 IPTV 환경이 조성된 어떤 조직에도 적용할 수 있는 최초의 속성인증 기법이다.

An estimation of the requirement of minerals based on growth stage and cropping pattern is very important for greenhouse zucchini. This study was performed at farmer's field which was applied with a fertigation system and a semi-forcing cultivation from Feb. to July in 2014, and nitrogen levels were set up with x0.5, x0.75, x1.0 and x1.5 of the NO3-N-based soil-testing recommendation for zucchini cultivation. Top dressing of nitrogen (basal : top = 4 : 6) and potassium (basal : top = 3 : 7) was applied with an interval of every two weeks from two and six weeks after transplanting, respectively, and phosphorus was totally supplied with basal dressing. The nitrogen uptake was the order of x1.0, x0.75, x1.5 and x0.5, phosphorus, x1.0, x0.75, x0.5 and x1.5, and potassium, x0.75, x1.0, x1.5 and x0.5. From these results, it was suggested that highest mineral uptake could be reached between x0.75 and x1.0 of the NO3-N-based soil-testing recommendation. In conclusion, nutrient management based on the growth stage was proven to be better method for favorable growth and yield of zucchini.

Objectives : Korean national health insurance data is a useful real-world data representing whole medical bills submitted to Health Insurance Review Agency. This study aims to understand recent benefit trend of insurance herbal preparations for treating bronchiectasis(disease code J47) utilizing insurance data. Methods : We reviewed national health insurance claims data from 2013 to 2017 which have main diagnosis or sub diagnosis code of J47 and with the record of prescribing insurance herbal medication. Frequency analysis was performed to analyze the most frequently prescribed prescription. Results & Conclusions : Both the number of claims statement(770 to 1,746cases) and patients(266 to 484) of insurance herbal preparations increased considerably from 2013 to 2017. Top 10 preparations based on the number of claims statement were 'Samso-eum', 'Yeonkyopaedok-san', 'Socheongryong-tang', 'Bojungikgi-tang', 'Hyangsapyungwi-san', 'Yijin-tang', 'Saengmaek-san', 'Jaeumganghwa-tang', 'Ojeok-san' and 'Gungha-tang'. Top 10 preparations based on the number of patients were 'Samso-eum', 'Socheongryong-Tang', 'Saengmaek-san', 'Yeonkyopaedok-san', 'Haengso-tang', 'Hyangsapyungwi-san', Yijin-tang', 'Jaeumganghwa-tang', 'Bojungikgi-tang' and 'Hyeonggaeyeongyo-tang' in respectiv order. Claims of top 10 frequent preparations occupied more than 60% of total claims. We hope this finding to be utilized as basic data for future research of evidence-based bronchiectasis treatment utilizing Korean traditional medicine.

Metal waste generated from the pyroprocessing of 10 MtU of spent fuel was classified by comparing the specific activity of a relevant radionuclide with the limit value of the specific activity specified in the Korean acceptance criteria for a lowand intermediate-level waste repository. A Korean Optimized Fuel Assembly design with a 17${\times}$17 array, an initial enrichment of 4.5 weight-percent, discharge burn-up of 55 GWD/MtU, and a 10-year cooling time was considered. Initially, the mass and volume of each structural component of the assembly were calculated in detail, and a source term analysis was subsequently performed using ORIGEN-S for these components. An activation cross-section library generated by the KENO-VI/ORIGEN-S module was utilized for top-end and bottom-end pieces. As a result, an Inconel grid plate, a SUS plenum spring, a SUS guide tube subpart, SUS top-end and bottom-end pieces, and an Inconel top-end leaf spring were determined to be unacceptable for the Gyeongju low- and intermediate-level waste repository, as these waste products exceeded the acceptance criteria. In contrast, a Zircaloy grid plate and guide tube can be placed in the Gyeongju repository. Non-contaminated Zircaloy cladding occupying 76% of the metal waste was found to have a lower level of specific activity than the limit value. However, Zircaloy cladding contaminated by fission products and actinides during the decladding process of pyroprocessing was revealed to have 52 and 2 times higher specific activity levels than the limit values for alpha and $^{90}Sr$, respectively. Finally, it was found that 88.7% of the metal waste from the 17${\times}$17 Korean Optimized Fuel Assembly design should be disposed of in a deep geological repository. Therefore, it can be summarized that separation technology with a higher decontamination factor for transuranics and strontium should be developed for the efficient management of metal waste resulting from pyroprocessing.
