The accurate forecasting of insurance claims is a critical component for insurers' risk management decisions. Hierarchical Bayesian parametric (BP) models can be used for health insurance claims forecasting, but they are unsatisfactory to describe the claims distribution. Therefore, Bayesian nonparametric (BNP) models can be a more suitable alternative to deal with the complex characteristics of the health insurance claims distribution, including heavy tails, skewness, and multimodality. In this study, we apply both a BP model and a BNP model to predict group health claims using simulated and real-world data for a private life insurer in Indonesia. The findings show that the BNP model outperforms the BP model in terms of claims prediction accuracy. Furthermore, our analysis highlights the flexibility and robustness of BNP models in handling diverse data structures in health insurance claims.

본 연구에서는 현재 한국 사회에서 가장 대표적인 디지털 컨텐츠 제품으로 등장한 온라인 게임 중 물리적으로 유사한 특성을 지니고 있지만 전혀 다른 형태의 세계로 발전해간 두 개의 제품, 리니지와 에버퀘스트를 대상으로 소비자의 게임 인식과 소비 행위에 따라 게임의 성격이 어떻게 다르게 규정되고, 그리고 소비자의 행동 특성이 특정 제품의 성격을 어떻게 변화시키는지를 탐색하였다. 첫째로 각각의 게임에 대한 소비자의 인식의 차이를 알아보기 위해, 게임의 매력과 만족을 주는 주된 활동, 친구관계, 캐릭터의 선택과 육성의 측면에서 비교해 본 결과, 리니지 게이머들은 리니지 세계를 현실과 유사한 가치와 의미를 지닌 새로운 생활공간으로 인식하고 있는 반면, 에버퀘스트 게이머들은 에버퀘스트 세계를 게임 자치로서의 기능에 초점을 둔 환타지 세계로 인식하고 있었다. 또한 게임 인식에 따른 게임 소비 행동을 게임 속 공동체 활동과 연애와 같은 사적인 관계의 측면에서 비교해본 결과, 구체적인 게임 소비 행동에서 차이가 나는 것으로 나타났다. 이러한 결과는 온라인 게임과 같은 사이버 공간의 가상의 디지털 이미지 또는 컨텐츠 제품들의 경우, 소비자가 지닌 경험이나 가치에 따라 제품에 대한 인식이 달라질 수 있으며, 이런 인식의 차이는 각각의 소비자들이 동일한 제품도 다르게 소비할 수 있음을 시사한다. 즉 디지털 이미지 또는 컨텐츠 제품들의 가치와 의미는 소비자에 의해 결정된다는 것을 시사한다고 할 수 있다.

Purpose: The purpose of this paper is to determine the effects of the Real Estate Transactions Tax (RETT) on the economic cycles of Saudi Arabia. A secondary purpose is to determine the effects of RETT on the construction and real estate sectors of Saudi Arabia. Research design, data and methodology: The data used is retrieved from the General Authority of Statistics, Saudi Central Bank and the World Bank Open Data. Econometric models of multiple linear regression with dummy variables have been conducted to achieve the objectives and to quantitatively verify the hypotheses. Results: With the VAT exemption in real estate transactions and its substitution with RETT, a positive effect on the economy and the real estate sector has been observed. However, this tax reform has not produced any significant effects in the construction sector. Conclusions: The main conclusion of the present research is that the real estate market has a major influence on economic cycles. After the tax reform, a reduction in the contribution of taxes on real estate transactions to GDP was detected. For the construction sector, after the tax reform, it is estimated that there will be an insignificant reduction in the contribution of the real estate price index, and of the taxes on real estate transactions, to GDP.

The purpose of this study is to suggest that activities consisting of sympathy and gratitude are the way to healing. In our team's Hope World (希望世上), we changed the lyrics of GunbamTaryeong, which Koreans know the most, to create a healing Taryeong. The iterative refrain changed to "It's nice, it's hope, it's a good world for everyone." "The Wind Blows, Spring Has Come, The Moon Is Bright" will be the beginning of each chapter in GunbamTaryeong. It looks like a bright lyric, but it also shows both sides. All members participated in changing the lyrics, harmonizing the lyrics and rhythm, preparing props, playing musical instruments, and exciting performances. Therefore, it can be said that it is the story of healing where everyone is together. The song of Hope World is a real Taryeong that heals those who plan together, sing together, play musical instruments together. It's a "hope-Taryeong (希望打令)" who dreams of a "everyone good world." It's a Taryeong that lingers in my mouth and comes to mind. In this way, activities consisting of mutual cooperation and love doubled gratitude and sympathy for each other, and we think healing was achieved in the process. In this study, we suggest that sympathy and gratitude are perhaps the first steps towards healing. The Hope World Song (希望世上歌) is available on our channel YouTube (https://youtu.be/hgPiD4g2-iM).

Pipe inspection has a great importance to ensure safety for the nuclear power plant. In this paper, we designed visual inspection module for the tube internal, which diameter is 15${\sim}$20mm. And we made inspection module which consisted of CCD camera and light. And the relation between image and real world coordinate is established. Image processing is performed to calculate mapping parameter and analyze the size of defect. For the calculation of mapping parameter, experiment is performed using grid type test pattern. Acquired image is processed to extract image coordinate. Edge detection, thresholding, median filtering and morphology filtering is applied to extract grid pattern. Extracted image coordinate is used to calculate image to real world mapping. Lens distortion was considered and corrected to get exact data. Coordinate transformation data is provided for the users to recognize easily. Experiment was performed using grid type test pattern, we extracted lens distortion parameter and real coordinate of defect point. Radial distortion of lens was corrected but tangential distortion was not considered. As continuum to this study, the tangential distortion of lens is considered and improvement of analy zing technique for the tube internal be explored continuously.

이 연구는 고속도로에서 발생한 교통사고에 대한 기하구조의 영향을 알아보고자 시도되었다. 기하구조의 경우에는 지침 등에서 정하는 기준 권장값등이 있지만, 기존의 사고모형에서는 교통사고에 영향을 미치는 기하구조의 자료가 통합된 형태로 사용되어 혼합된 형태로 설치된 현실을 추정된 모형이 제대로 설명하지 못하는 단점이 있다. 따라서 이 연구에서는 기하구조를 기준값에 의해 세분화된 기하구조 자료를 사용함으로써, 현실을 반영한 모형을 추출하고자 하였다. 그리고 각 기하구조별 탄력성 분석을 통해 사고에 미치는 영향을 제시하였다. 이는 향후 교통안전을 고려한 기하구조의 지침 정립에 도움이 될 것으로 사료된다.

The increasing size and complexity of modern construction projects demands mature capabilities of onsite personnel with regard to recognizing unsafe situations. Construction safety training is paper or computer-based and suffers from a distinct gap between the classroom training environment and real-world construction sites; even trained personnel can find it difficult to recognize many of the potential safety hazards at their jobsites even after receiving construction safety training. Immersive technologies can overcome the current limitations in construction safety training by reducing the gap between the classroom and a real construction environment. This research developed and tested a new Augmented Reality (AR)-based assessment tool to evaluate the hazard recognition skills of students majoring in construction management as part of a construction safety course. The quantitative and qualitative results of this research confirmed that AR-based assessment can become a very effective assessment tool to evaluate safety knowledge and skills in a construction safety course, outperforming both paper and computer-based assessment methods. The students preferred AR-based assessment because it provides a realistic visual context for real world safety hazards.

The purpose of this study is to consider the characteristics of character's body-image throughout the on-line games and with this study we researched the symbolic meaning reflected by the character's body-images throughout the fashion. The characteristics of the body-images presented in modern fashion is expressed in 4 features on Lineage II game. First, it adopts the ways in which modern fashion expresses the erotic image and represents various sexual stimulation, which can not be represented in the real world, in cyberspace. Second, it expresses the beauty and taste in sensitivity by exchanging the items, which are the features of body-image, each other as the neutral body-image and pursuits for the double side feature between males and females by dismantling the point of view to sex. Third, it shows the new value system different from the existing one by using extraordinary items and materials that you've never seen in real fashion as the abnormal body-image expressed in informal and inaccurate principal of deformation. Fourth, it show the body with the items which induces more interest and curiosity than the real world do as the humorous body-image accompanying with childish amusement and pleasure.
