While operating automatic tablet counter(ATC), there were filling error and filling time delay due to the breaking of tablets. This was presumed to happen mostly to uncoated tablet. This research was performed to show the adequate dosage form to operate ATC efficiently. As methods, error of stuck pills was analyzed by dosage form, distribution of dosage forms in ATC was examined in Korea and Japan. Stability was studied in terms of physical strength such as hardness and friability. The results show that 54% of stuck pills in the cassette of ATC during operation was uncoated tablet. The proportion of uncoated tablet, coated tablet, capsule in ATC was 67%, 34%, 19%, respectively in Korea, and was 9%, 64%, 26% respectively in Japan. The stability test of physical strength shows when the hardness were 1.5, 3.7, 6.6(㎏/cm2), the weight loss were 1.29%, 0.72%m 0.24% and when the friability 0.19%, 0.27%, 0.48%, the weight loss were 0.93%, 1.45%, 1.82%.

The effect of ultrasonic waves on formation and dissociation kinetics of gas hydrates has beenexperimentally studied by several researchers. Some results indicated that ultrasonic waves have theeffect of reducing gas hydrate induction time before the initiation of hydrate formation, while othersreported on the effect of prohibiting the growth kinetics during hydrate formation. There have also beenreports regarding an increase in the amount of gas consumed and a decrease in the hydrate formationtime. The present study examines the influence of ultrasonic waves on gas hydrate dissociation. Gashydrate formation and dissociation occurred in a temperature-controlled 15 L horizontal cylindricalreactor. The reactor was agitated with a pair offlat blades installed in radial direction and a pair of rollers,which were driven by a motor connected through a magnetic coupler. R-134a, a gas that can formhydrates at a relatively low pressure, was used to form gas hydrate slurry. Dissociation was augmented by20 kHz ultrasonic waves generated with a piezoelectric converter and transmitted through a vibratinghorn whose tip was in contact with the hydrated slurry in the reactor. To compare the effect of energyinput in the form of ultrasonic waves with that of the same amount of heat input, equivalent amount ofheat was provided to the reactor. Dissociation rate and the accumulated dissociation time were comparedbetween the cases of heat addition and ultrasonic wave irradiation. Results show that not only does thedissociation rate increase with an increase in the ultrasonic wave power, but the irradiation of ultrasonicwaves also enhances the dissociation of R-134a hydrate more effectively than the application of anequivalent amount of energy in the form of heat at the same location.

Purpose: This study is intended to understand the meaning and essence of the experiences of the students in art therapy master's course for art therapy in hospice care. Methods: Participants were five students in art therapy master's course. Data were collected through interviews and e-mail. They were analyzed using van Manen's hermeneutic phenomenology method. Results: Eight essential themes and 17 sub-themes were emerged. Conclusion: The art therapists who provided the hospice art therapy as a form of medical art therapy have led to the positive changes for everyone involved. Firstly, the art therapists provided the patients chances to do creative activities in the mundane hospital lives and to take stock of their past lives. Secondly, the art therapists gave the family members of the patients with the opportunities to express their pain and suffering. Thirdly, the art therapists had chances to think about their lives in a deeper way and grow mature as an individual being and an art therapist. In sum hospice art therapy provided meaningful opportunities to not only the dying patients but also everyone else involved regarding a variety of positive aspects including forgiveness, acceptance, understanding, and personal growth.

This study investigates the impact of SMEs and mid-sized firms’ R&D investment decision on export decision in the Korean electronics industry, and compares the size of the impact between subcontracting firms and independent firms. For empirical analysis, we estimate a dynamic structural model using plant-level panel data for the Korean electronics industry from the period 2012-2017. The empirical findings shows that subcontracting firms are slightly superior to independent firms in terms of the impact of R&D investment on exports. This result indirectly supports the fact that there are considerable number of subcontracting firms in Korea despite unfair subcontracting practices with large firms.

무인항공기 C2 링크 단절 비상절차 : 서울-제주 항로를 대상으로

홍혜정,주태현,김상현 한국교통연구원 2017 交通硏究 Vol.24 No.4

ICAO(International Civil Aviation Organization)는 2030년 이후 유인항공기와 무인항공기를 함께 운영하겠다는 통합운용계획을 세웠으며 우리나라도 이에 맞추어 관련 연구를 진행하고 있다. 무인항공기는 기존의 조종석을 지상으로 가져온 RPS와 무인항공기인 RPA를 연결해주는 C2 링크에 의해 통제된다. 따라서 C2 링크 단절 시 지상에 있는 조종사는 무인항공기의 통제를 잃게 되며 안전에 심각한 위험을 초래할 수 있다. 본 연구는 세계적으로 승객수가 가장 많은 노선인 서울-제주 항로에 대해 ICAO RPAS 패널에서 논의된 사항을 바탕으로 C2 링크 단절 비상절차 시나리오를 수립하였다. 서울-제주 항로는 1시간 이내의 비행시간을 가지는 비교적 짧은 항로이며, 양방향 단일 노선에서 현재는 단일방향 두 개의 노선으로 복선화하여 운영되고 있다. 이러한 특성을 반영하여 C2 링크 단절 비상절차를 비행계획 유지와 회항이라는 두 가지 시나리오로 도출하였다. 회항은 지정된 장소에서 체공하며 C2 링크 복구 시도 후 실패 시 진행하는데, 이 때 구 항로를 이용하는 것과 반대편 신 항로를 이용하는 경우로 나누어 제시하였다. 본 연구에서 수립한 비상절차 시나리오가 향후 우리나라의 안전한 유, 무인항공기 통합운용에 기여할 수 있을 것으로 기대한다. International Civil Aviation Organization(ICAO) established a plan to integrate unmanned aircraft operations into manned airspace by 2030 and Korea conducts research efforts along with the ICAO’s plan. Remotely Piloted Aircraft System(RPAS) consists of Remote Pilot Station(RPS), which is the cockpit on the ground, Remotely Piloted Aircraft(RPA), and C2 link that connects the RPS and the RPA. Hence, a remote pilot loses control over the RPA when the C2 link is lost, and this situation can pose a serious risk to safety. This study suggests lost C2 contingency procedures for RPAS on Seoul-Jeju route, which is the busiest air route in terms of the number of passengers. The suggested contingency procedures are based on the discussions in the RPAS panel of the ICAO. Seoul-Jeju route is short with about 1 hour flight time. The route was previously single but now is parallelized. The lost C2 contingency procedures have two different scenarios: continue on the flight plan and return to the base. The “return to the base” is conducted when C2 link recovery is failed, and there are two options again: use the old route and the new route. The suggested contingency procedures are expected to contribute to the safe integration of manned and unmanned operations in the future.

Objectives: The purpose of this research is to investigate clinical studies of essential tremor in China. Methods: We investigated clinical studies of Traditional Chinese Medicine therapies in traditional Chinese medical journals for essential tremor through the China National Knowledge Infrastructure (CNKI) database. In total, 15 clinical articles were analyzed. This study examined the authors; published years; types of study; treatment methods for the treatment and control groups; periods; outcome assessment; and results. Results: Nine articles used acupuncture, 6 articles used herbal therapy. The most commonly used acupoints were GV20, GB20, LR3, LI4, GB34, SP6, and EX-HN1. The most commonly used herbs were Paeoniae Radix Alba, Angelicae Gigantis Radix, Cnidii Rhizoma, Gastrodiae Rhizome and Uncariae Ramulus et Uncus. Total effective rate was 66.67-96.7%; the treatment group values were significantly higher than the control group values in all papers. Tremor score, HAMD, curative effect of TCM syndrome, and incidence of adverse effects were significantly more affected in the treatment group than in the control group. Conclusion: More active clinical studies are needed on essential tremor, and the results of this study can be used as a basis for future research.

야식증후군 진단질문지(NEDQ)의 타당화 연구

홍혜정,박중규 한국임상심리학회 2019 한국심리학회지: 임상심리 연구와 실제 Vol.5 No.1

본 연구는 야식증후군의 진단기준에 따라 Nolan 등이 2001년에 개발하고 2016년에 개정한 야식증후군 진단질문지(Night Eating Syndrome Diagnostic Questionnaire: NEDQ)를 한국어로 번안하고 이의 타당화를 목적으로 수행되었다. 이를 위해 대구․경북의 대학(원)생 766명을 대상으로 연구를 실시하였으며, 이 중 60명에게 4주 간격으로 검사-재검사 신뢰도를 실시한 결과, 양호한 수준으로 나타났다. 이와 함께 NEDQ는 기존의 야식증후군 척도와도 유의한 상관이 나타났으며, 부정 정서 조급성과 우울, 폭식행동, BMI 및 섭식 기대와도 정적인 상관을 나타냈다. NEDQ를 심각도에 따라 분류한 뒤 변인들 간의 성별 차이를 살펴본 결과, 야식증후군이 심각한 집단에서 남성이 여성보다 부정 정서 조급성과 섭식 기대 및 폭식행동의 점수가 높게 나타났다. 이로 인해 남성이 경미한 수준에서의 부정적인 정서와 야식 및 폭식과 같은 이상 섭식행동에 대해 둔감한 태도를 가지고 방치하다 심각한 수준에 이를 수 있음을 추측해 볼 수 있다. 본 연구는 국외에서 개발된 야식증후군 측정도구를 국내에서 타당화 연구를 진행하여 향후 임상적으로 유용한 도구를 제공할 수 있다는 점에서 의의가 있다. 또한, 야식증후군에 기여하는 심리적 특성들의 임상적 영향력을 확인함으로서, 반복적인 야식 문제를 가진 개개인에게 구체적인 중재를 제공할 수 있을 것이다. The purpose of this study was to translate the Night Eating Diagnostic Questionnaire (NEDQ), developed (2001) and revised (2016) by Nolan et al., into Korean and to test its validation. After translating it into Korean, the NEDQ was distributed to 766 individuals, and 60 of the subjects took a test-retest with an interval of four weeks between the tests. The retest reliability coefficient was good. Correlation analysis was conducted to examine its correlations with the Korean Version of the Night Eating Syndrome Scale, which had been already developed in Korea, to test its validation. The analysis results showed significant correlations. Also, the NEDQ had significant correlations with negative urgency, depression, binge eating, BMI, and eating expectancy. Since previous studies on eating disorders reported higher prevalence in women, the present study analyzed gender differences on the NEDQ to see whether such differences would also be found on the Night Eating Syndrome Scale. Female college students scored significantly higher on average than their male counterparts. Male college students, however, scored higher than females on negative urgency, eating expectancy, and binge eating in cases of serious Night Eating Syndrome; this is because men have insensitive attitudes toward their eating behavior and negative urgency, thus neglecting these and reaching serious levels. The present study is significant in that it conducted validation research on the Night Eating Syndrome Questionnaire in Korea, providing a clinically useful instrument. In addition, it checked the clinical influence of psychological traits contributing to the syndrome, offering specific interventions to individuals with the issue of repeating night eating.

The purpose of this study was to investigate that the character of language development by children and the influence that aggressive and prosocial behavior on focusing two years old. The target on this study 208 two years old children. This study was to check socio-demographic items to find differ depend on sex and monthly age by two years old children’s mother. And the character of language development was to assess their mother and the aggressive and prosocial behavior to assess their teacher. So this study collected 208 two years old children data for statistics analysis to use SPSS 20.0. At the result this study follow that; At first, language development of two years old children was not to relate by sex, but to relate by monthly age. Second, ‘express language’ were found to negatively influence their ‘language aggression’ as subscale for aggression, but ‘receptive language’ were not found to significantly influence aggression of two years old children. Third, ‘express language’ were found to positively influence prosical behavior for all subscale, but ‘receptive language’ were not found to significantly influence for statistic. This study results were to suggestive that language development of two years old was to influence their aggressive and prosocial behavior. So it seems to contribute to use basic information for pervasive development on childhood.
