This study was aimed to analyze the increased forestry incomes by combining timber production and wood processing, which is one of 6th industrialization types in Korean forestry. The selected household has been engaged in forestry for two generations and they produce timber and associated wood products in their own facility. The wood products include dimension lumber, interior wood material, cutting board, and cube chips, the household also utilize logging and sawmill residues as well as seed and seedlings as by-products. Incomes and expenses that have been incurred on individual processes of the sequential timber production and wood processing were surveyed, and we analyzed the economic outcomes of entire business. The results of this study indicate that the gross income of the household is 122.3 million Korean won and the net income is 93.6 million Korean won. The net income of the household is approximately 2.8 times higher than the average net income of whole households in the forestry of Korea in 2016, which is approximately 4.3 times higher than that of households that have been particularly engaged in timber production over the country. We found that the 6th industrialization by combining the two sequential processes creates approximately 3.2 times as much added value compared to the case relying on timber production only.

본 연구는 인지내용이 정서장애에 영향을 미친다는 인지적 내용-특수성 가설에 근거하여 불안장애환자의 사고내용을 조사하고자 했다. 사고내용에 있어서, 불안장애 환자들이 정상인 또는 비불안 정신장애환자와 어떤 차이점이 있는지를 조사했으며 나아가서 불안장애의 하위유형인 공황장애환자와 비공황 불안장애환자간에 어떤 차이점이 있는지를 탐색하고자 했다.이를 위해서 공황장애환자 34명, 비공황 불안장애환자 24명, 비불안 정신장애환자 34명을 포함한 92명의 정신장애 환자와 60명의 정상인을 대상으로 하여 그들의 사고내용을 측정하였다. 이들의 사고내용은 불안민감성 척도(ASI), 광장공포인지 질문지(ACQ), 신체감각 질문지(BSQ)를 사용하여 측정되었다. 각 집단별 사고내용을 정밀하게 비교하기 위하여 각 척도의 개별문항에 대해서 차이비교검증을 실시하였다.본 연구의 주된 결과는 다음과 같다. 첫째, 공황 장애를 비롯해 불안장애 환자집단은 정상인 집단에 비해 세 척도에서 측정된 불안유발 사고내용을 현저하게 많이 가지고 있었다. 둘째, 공황장애 환자집단은 비불안 정신장애 환자(우울증 및 신체화) 집단에 비해 신체적 증상에 대해서 더 예민하고 이를 위협적인 것으로 평가하는 경향성이 있었다. 셋째, 공황장애 환자들은 비공황 불안장애 환자나 비불안 정신장애환자에 비해 극단적이고 파국적인 위험과 관련된 사고내용을 많이 가지고 있었다. 특히 공황장애 환자들은 다양한 신체적 증상과 변화에 예민하고 이를 죽음이나 통제상실상태와 같이 극단적이고 파국적인 것으로 해석하는 사고경향이 있는 반면, 비공황 불안장애 환자들은 대인관계에서의 부적절한 대처나 능력에 대한 부정적 평가와 같이 일반적이며 비파국적인 위험이나 위협과 관련된 사고내용을 많이 갖는 경향이 있었다.ABSTRACT The aim of the present study is to investigate some characteristics of patients with anxiety disorders in their thought contents from the theoretical perspective of the cognitive content-specificify hypothesis that cognitive contents influence emotional disorders. For this, differences in thought contents between patients with panic and non-panic anxiety disorder as well as between patients with anxiety disorders and non-anxiety psychiatric patients or nomal controls were examined.The data were collected from 92 psychiatric patients (34 panics, 24 non-panics, 34 non-anxiety psychiatric patients) and 60 normal controls. Their thought contents were measured with the Anxiety Sensitivity Inventory, Agoraphobic Cognition Questionnaire, and Body Sensation Questionnaire. The difference between groups in the individual item of the three measures was tested using ANOVA and multiple comparison tests.The main findings in the present study are as follows: First, the patients with anxiety disorders reported significantly more thoughts with anxiety-provoking contents than normal controls. Second, the patients with panic disorders tended to be more sensitive to physical symptoms and to interpret these as being threatening than the non-anxiety psychiatric patients. Third, the patients with panic disorder had more thoughts with contents related to extreme and catastrophic danger than those with non-panic anxiety disorders. In particular, those with panic disorder had strong tendency to be senstive to physical symptoms or changes and to interpret these as suggesting extreme and catastrophic danger such as death or loss of control, whereas those with non-panic anxiety disorders tended to have thoughts with contents related to general and non-catastrophic danger or threats such as inadequate coping in interpersonal situations or negative evaluation about their ability.

The basic aim of this study is to utilize PCM(Phase Change Material) that is required for storage of solar energy. PCM's thermal, physical characteristics are affected by temperature. PCM is easy to change one into another phase at low temperature. While the temperature change makes the PCM melted or solidified, an amount of energy can be transfer. In order to evaluate the PCM's characteristics and its phase change related to heat transfer, 3 dimensional computer simulation is adapted and its analysis is accomplished. The simulation was carried out under changing of temperature for an insulated cylinder filled with PCM and the PCM's thermal characteristics was observed based on time.

본 연구는 주부들의 스트레스를 알아보고자 주부들이 경험하는 생활 사건을 조사하였다. 179명의 주부를 대상으로 자료를 수집해 취업 여부및 연령별로 분석하였다. 주부들이 지난 1년 동안 가장 많이 경험한 생활사건은 '식습관의 변화'였으며, 가장 부정적으로 평가한 생활사건은 '배우자 사망'과 '직장 퇴직'이었고 가장 긍정적으로 평가한 생활 사건은 '약혼'이었다. 취업주부는 전업주부에 비해 '개인적 일을 성취한 경험'이 더 많았으며 그것을 더 긍정적으로 평가하였고, '배우자와 다투는 횟수의 변화'와 '배우자와 화해한 경험'은 전업 주부에게서 더 많았다. 연령별 차이를 보면, 연령이 높아질수록 긍정적으로 평가하는 생활경험이 적었지만 부정적으로 평가하는 생활사건에서는 차이가 없었다. 마지막으로 본 연구의 제한점과 앞으로의 연구방향이 제시되었다. This study attempted to examine the life events that wives experience. The data from 179 wives were analysed with respect to employment and age. The results revealed that the most frequent life event during the past 1 year was 'change in eating habits'. And the most negative events were 'death of spouse' and 'retirement from work'; and the most positive event was 'engagement'. Working wives experience more positively than unemployed wives. Unemployed wives experienced more 'major change in number of arguments with spouse' and 'marital reconciliation with mate' than was no difference due to age in the negative life events. Finally, the limitations of this study and the suggestions for future research were discussed.

국내의 일부 은행은 매일 오전 외환시장의 동향에 대한 정보를 제공하면서 환율의 금일변동의 예상범위를 제시하고 있다. 본고에서는 그 중 한 일반은행을 택하여 금일예상범위에서 제시된 일별 원/달러 환율의 예측치의 예측력을 분석하고, 시계열모형을 통한 예측력의 개선방안에 대해 연구하였다. 이 은행에서 제시하는 환율예측치를 벤치마크로 삼아 ARMA모형, GARCH모형, 지수평활화, 임의보행모형 등의 시계열모형의 예측치와 비교·분석하였다. 리먼 브라더스의 파산으로 촉발된 2008년 하반기의 국제금융의 위기로 인한 환율의 급격한 변동을 반영한 분석도 시도하였다. 예측의 편의성(biasness)을 검정하기 위한 MFE 통계량, 예측력의 우월성을 비교하는 RMSFE 통계량, 예측력의 통계적 차이를 검정하기위해 Diebold and Mariano 검정방법, 환율변동 방향에 대한 예측력을 검정하기 위해 DOC기준을 각각 사용하였다. 분석 결과 이 은행의 예측치가 다른 시계열 예측치보다 우수한 예측력을 가지는 것으로 나타났다. 국제금융위기로 변동성이 심해진 기간을 감안한 분석의 결과도 비슷하게 나타났다. 이 은행의 예측치와 시계열 모형 예측치를 반영하는 결합예측치를 만드는 경우 은행의 예측치가 가지는 편의성이 대폭 개선되는 것으로 나타났다. 그리고 예측력도 제한적인 범위에서 개선이 있는 경우도 나타났다. 특히 변동방향의 예측에서 상당한 정도의 개선이 있는 것으로 나타났다. This study investigates the performance of a major commercial bank in Korea in terms of forecasting daily exchange rates. The paper suggests several alternative forecasting methods based on time series models, including ARMA, GARCH, GARCH with a structural break, exponential smoothing, the random walk model. The out-of-sample forecasting performance of the bank`s forecasting method was compared with that of the alternative forecasting methods by using the root mean squared forecast error (RMSFE) and the direction of change (DOC). The results indicate that the bank`s forecasting method has a clear advantage over the alternative methods. However, the bank`s forecasting method offers no advantage in terms of the mean forecast error (MFE). The forecasting methods were then combined to improve forecasting performance. The results do not provide evidence of such an improvement in terms of the MSFE but indicate a significant reduction in forecast bias and an increase in forecasting performance in terms of the DOC.
