ASMR are becoming a new consumption trend with wide prevalence of personal web-casting and video-sharing platforms. In this context, this research looked at what factors determine usage of ASMR contents. In greater details, demographic variables, sub-types of contents, usage motivations, neuroticism and subjective norm were considered as possible determinants in this study. And their influences on ASMR usage were empirically tested. The moderating effect of neuroticism was also examined. The findings showed that educational level as one of demographic variables, two sub-types of scratching and eating sound, three motivational factors including attention, relieving for sleep disorder and pleasure stress relief have positive influences on ASMR usage while motivations of curiosity trend and sexual pleasure have negative influences. The moderating effect of neuroticism was also empirically proven. This study has implications since it suggests that personal traits including neuroticism as influencing factors should be taken into account in understanding usage behaviors of ASMR contents with accuracy.

We examine how to model mortality risk using the adaptation of the mean-reverting processes for the two factor model proposed by Cairns et al. (2006b). Mortality improvements have been recently observed in some countries such as United Kingdom; therefore, we assume long-run mortality converges towards a trend at some unknown time and the mean-reverting processes could therefore be an appropriate stochastic model. We estimate the parameters of the two-factor model incorporated with mean-reverting processes by a Metropolis-Hastings algorithm to fit United Kingdom mortality data from 1991 to 2015. We forecast the evolution of the mortality from 2014 to 2040 based on the estimation results in order to evaluate the issue price of a longevity bond of 25 years maturity. As an application, we propose a method to quantify the speed of mortality improvement by the average mean reverting times of the processes.

In a typical trend-cycle decomposition of GDP, the trend component is usually assumed to follow a random walk process. This paper considers an ARIMA trend and assesses the validity of the ARIMA trend model. I construct univariate and bivariate unobserved-components(UC) models, allowing the ARIMA trend. Estimation results using U.S. data are favorable to the ARIMA trend models. I, also, compare the forecasting performance of the UC models. Dynamic pseudo-out-of-sample forecasting exercises are implemented with recursive estimations. I find that the bivariate model outperforms the univariate model, the smoothed estimates of trend and cycle components deliver smaller forecasting errors compared to the filtered estimates, and, most importantly, allowing for the ARIMA trend can lead to statistically significant gains in forecast accuracy, providing support for the ARIMA trend model. It is worthy of notice that trend shocks play the main source of the output fluctuation if the ARIMA trend is allowed in the UC model.

수분 이용효율(Water Use Efficiency, WUE)은 식생이 흡수한 수분 중 증발산에 이용한 비율로, 육상생태계의 수문학적 순환 및 탄소 순환의 기능을 측정할 수 있는 중요한 지표이다. 또한 이는 특정 지역의 기후 조건이나 토지 피복과 같은 다양한 요인에 따라 변할 수 있다. 본 연구에서는 한반도에서 2010년부터 2014년까지의 기후 요인(강수, 기온)과 토지 피복에 따른 WUE의 변화를 살펴본다. MODerate resolution Imaging Spectroradiometer (MODIS) 기반 총일차생산성(Gross Primary Productivity, GPP), 증발산량(Evapotranspiration, ET), 잎면적지수(Leaf Area Index, LAI)와 Willmot의 기상자료 등 대상지역에 대한 격자 자료를 사용한다. 구체적으로 숲, 초원, 농지와 같이 다양한 토지 피복 조건에 대한 월간 및 연간 WUE(=GPP/ET)를 산정하고, 이의 LAI나 기후 조건(강수, 기온)과의 관계를 분석하고자 상관성 및 요인 분석을 진행한다. 기후 조건 및 토지 피복 조건을 고려한 15년간 한반도에서의 WUE의 변화에 대한 분석은 앞으로의 수자원 관리 및 산림 정책에 활용할 수 있을 것으로 판단된다.

This study examined the factors for feelings of emptiness on Facebook use, and how these feelings are related to the user's personal attributes and the addiction to Facebook usage. For analysis, the factors for feelings of emptiness on Facebook use among college students were measured and a questionnaire was developed. After analysis, 3 factors were identified: 'isolation and loneliness', 'self-regulation disorder', and 'unreality'. Then, variables influencing the feelings of emptiness were identified. Among big 5 personalities, neuroticism, agreeableness, and openness to experience were related to the factors for feelings of emptiness. The study also found that motivations such as 'self-disclosure' and 'social pressure from others' tended to enhance the feelings of emptiness. Finally, the study examined the relationship between feelings of emptiness on Facebook use and the addiction to it. Factors of 'isolation and loneliness' and 'unreality' revealed more addiction tendency on Facebook.

When investigating the damage of a forest fire, quite a few are depending on the naked eye observation. However, if the damage spreads to another area, it is easy to use the satellite images because it is hard to reach all the damaged areas on foot. From this research, we did a statistical interpretation of after fire using satellite image data to classify the damage on first and second factor analysis. As a result, it was more easier to classify the river's plants and ridges between rice fields that were in the forest fire damage area in the second observation then the first observation. Also, we could classify the area by areas that were damaged more or less using the second factor analysis. To verify this, we used the forest fire images collected from the satellite images and the actual survey data collected from spectral radiometer to see if these two datawere correlated and as a result we found out that they were highly involved.

This study examined the predisposing, enabling and need factors, based on Andersen's behavioral model, affecting intention to use community organizing services at a community welfare center. 725 people aged 20 and older who lived in Gwang-jin-gu participated in this study and multiple linear regression analyses were utilized to analyze the deputation. The results demonstrate that intention to use is primarily affected by predisposing factors, age and duration of education. Female and more educated people were significantly associated with the intention to use community organizing services. Enabling factors, reputation and image of the community welfare center significantly affect intention to use community organizing services. People are more likely to use community organizing services when there is higher reputation of the community welfare center and better image of the community welfare center. Finally, intention to use is primarily affected by welfare consciousness, a need factor. People who have liberal welfare consciousness are more likely to use community organizing services. These findings provide implications and suggestions for increasing intention to use community organizing services at a community welfare center.

This study was conducted to find out the effect of job-crafting of social workers at community children's centers on the satisfaction of children. This study used a multi-level analysis model that calculated the child factor (level 1) and the social worker factor (level 2) by utilizing the responses of 31 social workers and 216 children used at 31 community children's centers. The main research results are as follows: First, it was found that 34.3% of the total variation in child satisfaction was due to differences by community children's centers. Second, it was found that the number of hours used per day in the child factor (level 1), and gender, age, and job-crafting in the life worker factor (level 2) affect the satisfaction of children. Based on these results, measures to improve the satisfaction level of children using community children's centers were discussed.
