식생의 광학적 특성을 기반으로 만들어진 식생지수들은 식물의 생물생산량뿐만 아니라 생리적 활성을 나타내고 있다. 식생지수의 활용은 위성에 장착된 다중분광 광학 센서의 발달에 힘입은 바가 크지만, 관측 공간규모에 따라 식생지수의 민감도가 달라질 수 있어 여러 규모에서의 비교 관측이 요구된다. 특히 광화학반사지수(PRI, Photochemical Reflectance Index)는 광합성능과 식물 스트레스 탐지에 유용한 것으로 알려져 있지만 올바른 해석을 위한 다양한 공간규모에서의 선행연구가 드물다. 본 연구에서는 드론에 장착된 다중분광 카메라, 소형 필드 초분광계, 휴대용 잎 반사계를 이용해 마늘 작물을 대상으로 서로 다른 공간규모의 PRI를 평가하였다. 잎 규모에서 하루 중 PRI는 잎의 윗면이 향하는 방위에 따라 서로 다른 시간에 최저값을 보였으며, 이는 어떤 순간에 잎마다 다른 광이용효율(LUE, Light Use Efficiency) 상태라는 것을 의미한다. 잎 규모에서는 식생피복율에 영향을 받지 않으므로 PRI 생물계절적 변화는 생육 초기에 개체 및 군락 규모보다 값이 높게 나타났다. 개체 및 군락 규모에서 PRI는 생물량을 나타내는 NDVI(Normalized Difference Vegetation Index)와는 달리 공간적 변동성이 크게 나타났다. 반면, 지상의 개체들 규모의 식생지수를 드론 영상의 관측 지점 값과 비교해 보면 NDVI에 비해 PRI가좀더 좋은 일치도를 보였다. 이러한 결과는 서로 다른 공간규모에서 관측된 PRI를 이해하고 활용하는데 도움이 될 것이다.

Time series of gridded surface wind and wind-stress vectors over the world ocean have been constructed by satellite scatterometer data. The products are derived from the ERS-l,2 covering 9 years during 1992-2000 and the Sea Winds on board QuikSCAT (Qscat) which has been operating up to the present since June 1999, so they allows us to analyze variabilities with various time scales. In this study, we focus on interannual variability of the wind stress in the mid- and high-latitude region of North Pacific. These are compared with those by numerical weather prediction(NWP) ones (NCEP Reanalysis). We also examine variability in the wind-stress curl field that is an important factor for ocean dynamics and focus its time and spatial characters in the northwestern Pacific around Japan. It is found that the vorticity field in the lower atmosphere tends to increase gradually with time, suggesting the enhancement of the North Pacific subtropical gyre.

Objectives: The purpose of this study was to introduce the progress of treatment and improve clinical use after conducting Mentalizing the Rooms of Mind, the main technique of Mindfulness & Loving Beingness psychotherapy, for a patient with panic disorder. Methods: We conducted a Mentalizing the Rooms of Mind for 10 sessions on an age 23 female diagnosed with panic disorder based on the DSM-5 diagnostic criteria. After receiving consent from the subject, through chart review, the progress of treatment was observed focusing on the MMPI-2 and CSEI-s (The Core Seven Emotions Inventory-short form) conducted pre- and post-treatment. This study was approved by the Institutional Review Board of Wonkwang University Sanbon Hospital (WMCSB202007-55). Results: 1. The MMPI-2 clinical scales of an age 23 female with panic disorder showed a 7 (Pt)-1 (Hs)-3 (Hy) profile pre-treatment, but for post-treatment, the scale showed 1 (Hs)-3 (Hy) profile, and the 7 (Pt) scale showed significant decline. In the MMPI-2 reconstructed clinical scales, RC7 (Dysfunctional Negative Emotions) and RC8 (Aberrant Experiences) showed significant decline. 2. In the pre- and post-treatment MMPI-2 content scales, Anxiety, Fears, Obsessiveness, Social Discomfort, and Work Interference scores decreased, showing overall positive stability. On the MMPI-2 supplementary scales, the Anxiety and Post-Traumatic Stress Disorder scores decreased, and the Ego Strength increased, resulting in improved overall psychological adaptation. 3. Pre- and post-treatment of an age 23 female with panic disorder, CSEI-s showed significant decline of 恐, 驚, 悲, and 思. So it seems that the emotions caused by Chiljeongsang (七情傷) were more stable than before treatment. Conclusions: As shown above, the treatment of panic disorder through Mentalizing the Rooms of Mind, a major technique of Mindfulness & Loving Beingness psychotherapy, showed positive changes in MMPI-2 as well as improvement of the subjective symptoms. Thus, Mentalizing the Rooms of Mind has high clinical use, and it seems that it is necessary to create a manual for this in the future.

Objectives This study is to investigate domestic trends of chuna manual therapy on traffic accident for recent 10 years. Methods We searched the studies on chuna manual therapy for traffic accident in 6 Korean web databases. Consequently, 17 research papers were founded. We analyzed these papers according to their published year, the titles of journal, the type of study, the number of cases, the sites of injury, assessment scales of study, and ethics of research. Results 17 papers were published since 2005. The studies on chuna manual therapy about traffic accident were mainly published in the journal of korean society of chuna manual medicine for spine & nerves and the journal of korean medicine rehabilitation. All papers were clinical research include 2 case series, 2 non randomized controlled trials (NRCTs), 13 randomized controlled trials (RCTs). The most frequently occured symptom was neck pain. In assessment scales, visual analog scale (VAS) was mainly used. All clinical studies were not mentioned about approval of institutional review board (IRB). Conclusions In this study, we analyzed the trends of chuna manual therapy on traffic accident in Korea from 2005 to 2014. In reviewing published papers, we found several weak points in methods of research and quality of study protocol. It is needed to adjust these problems for development of future researches.

Objectives: This study aims to investigate the factors related to Korean physicians' trust in the government. Methods: We used structured questionnaires that were composed of multidimensional scales for each of the various categories. Results: The recognition levels of trust of the government by Korean physicians were not high, and they ranged from 3.6 to 4.8 for ten scales. The factors related to trust in the government were categorized into seven factors on the basis of a factor analysis. On the regression analysis, a positive relationship was found between "the individual propensity to trust" and trust in the government, while a negative relationship was found between "the recognition level regarding the government as an authoritarian power" and trust in the government. "Confidence about participation in the policy process" as internal efficacy and "belief in governmental ability and motivation toward public demand" as external efficacy also showed a strong positive relationship with trust in the government. Conclusions: From these results, we can draw the conclusion that making efforts to improve the recognition level of trust in the government among physicians is an important policy task. To increase the trust level, participation of physicians in the policy process in various ways and open communication between the physicians' associations and the government should be facilitated.

During a major solar eruption, the erupting plasma is possibly out of the equilibrium ionization state because of its rapid heating or cooling. The non-equilibrium ionization process is important in a rapidly evolving system where the thermodynamical time scale is shorter than the ionization or recombination time scales. We investigate the effects of non-equilibrium ionization on EUV and X-ray observations by the Atmospheric Imaging Assembly (AIA) on board Solar Dynamic Observatory and X-ray Telescope (XRT) on board Hinode. For the investigation, first, we find the emissivities for all the lines of ions of elements using CHIANTI 8.07, and then we find the temperature responses multiplying the emissivities by the effective area for each AIA and XRT passband. Second, we obtain the ion fractions using a time-dependent ionization model (Shen et al. 2015), which uses an eigenvalue method, for all the lines of ion, as a function of temperature, and a characteristic time scale, $n_et$, where $n_e$ and t are density and time, respectively. Lastly, the ion fractions are multiplied to the temperature response for each passband, which results in a 2D grid for each combination of temperature and the characteristic time scale. This is the set of passband responses for plasma that is rapidly ionized in a current sheet or a shock. We investigate an observed event which has a relatively large uncertainty in an analysis using a differential emission measure method assuming equilibrium ionization state. We verify whether the observed coronal plasmas are in non-equilibrium or equilibrium ionization state using the passband responses.

A major change occuring in the workplace is the willingness of union leaders, managers, and workers to experiment with various work schedules and to work toward the improvement in the QWL(quality of work life). In this study, the writer measures the level of QWL, embodies components of QWL, testifies the difference of QWL according to the demographical traits, and develops some scales to measure QWL in merchant ships. To achieve objectives of the paper, 11 hypotheses were established and a questionnaire was used, 894 proper data was obtained from 2, 910 Korean seamen working in merchant ships. Results of analyses are as follows : 1) The components of QWL in merchant ships are job, employee satisfaction, wage, welfare, working condition, supervise, colleague relations, initiative, and organization management. 2) Seamen of merchant ships are satisfied with job, supervise, colleague relations, and organization management. They are dissatisfied employee satisfaction, wage, welfare, and working condition. 3) According to demographical traits, the number of the factors significant difference(P<0.05) among components of QWL are 9 for type of ships, 8 ages of seamen, 7 for married or single, nationality of ships, and education level respectively, 5 for seamen career, for 4 rank on board and trading route of ships respectively, 2 for whether union or not and whether union involvement or not respectively, and 1 for department on board. 4) Results which tested hypotheses are as follows : For the components of QWL, married men are more satisfactory than an unmarried men, officers are more dissatisfactory than ratings, old men are more satisfactory than young men, men in high education level are more dissatisfactory than men in low education level, those who are much careers as a seaman are more satisfactory than those who are little careers as a seaman. There are significant differences in the components of QWL according to nationality and type of ships. There are insignificant differences in the components of QWL according to the shipboard department, whether union is or not, whether union involvement is or not, and trading route of ships.

Objectives : This article aims to give guidance on the conduct and reporting of case series and audits of acupuncture, based on common problems that have arisen in the past. This type of project, and particularly the prospective case series or pre- post-intervention study, may give valuable evidence of the overall effectiveness of acupuncture-for example in different situations and in different conditions- and provides one step in the research pathway before generating an hypothesis. Results & Discussion : The project should be designed with the aim of reducing bias as much as possible. Careful and detailed planning is essential for the project to produce worthwhile results that readers can evaluate and replicate. Ethical issues should be considered and formal approval may be necessary. The patient group should be recruited systematically and baseline data obtained. The treatment given should be systematic and decisions to change or end treatment made explicit. The outcome should be measured in ways that are known to be reliable and valid. Musculoskeletal problems can be evaluated with scales for pain and confirmed by measuring one other symptom such as stiffness or one other aspect such as bothersomeness. Global change scores also provide supporting information, and the MYMOP (Measure Yourself Medical Outcome Profile) measure is popular when patients with different conditions are included. The design of questionnaires for beliefs and attitudes is a specialised area that should not be attempted without expert help. Adverse events should also be recorded. Analysis of the data and the best way of summarising and presenting the results are also discussed.

화물차량의 과적은 도로 포장의 파손 및 교량 등 도로구조물의 파괴, 대형 교통사고 발생 등의 주요한 원인 중 하나로서 오랜 시간동안 도로 교통 분야에서 중요한 연구분야였다. 본 연구에서는 과적 문제 해결을 위해 급속도로 발전하는 IT 및 빅데이터 활용기술을 접목하여 화물차량의 과적운행패턴 분석 및 차체부착중량계중시스템를 활용한 과적예방 효과를 분석하였다. 이를 위해 기존 화물차량과적 관련 문헌 조사와 상용 차체부착중량계중시스템 기술 조사를 진행하였으며, 과적적발 정보 분석을 통해서 대표적인 과적차량의 유형을 선정하였다. 과적유형에 맞는 차량을 10대 선정, 차체부착중량계중시스템을 설치함으로써 화물차량의 정보를 실시간으로 모니터링하여 연구 데이터를 수집하였다. 화물차량의 축중량과 총중량 데이터는 상하차 작업횟수 대비 과적비율 등으로 분석하였으며, 차체부착중량계중시스템 유무에 따른 그 변화추이를 확인하여 차체부착중량계중시스템 적용의 과적예방효과를 확인할 수 있었다. 다만, 시험차량 표본수가 전체를 대표할 수 있을 정도로 충분하지 못하기 때문에 향후 확대 시험을 통해서 추가적인 연구가 가능할 것으로 판단된다.
