본 연구는 공포 장르 중에서 영화와 게임의 요소 측면에 초점을 맞추고 있다. 공포 영화의 카메라 앵글과 공포 게임의 구도는 사람에게 공포심을 유발할 주요한 요인이다. 본 연구는 4가지 공포요소(감각적 공포요소, 기대적 공포요소, 제한적 공포요소, 수행적 공포요소)를 분석하여 구도와 카메라 앵글의 패턴과 결합해서 분석하였다. 알플레드 히치콕 감독의 영화에 적용한 기법과 게임 구도의 구성 형태는 어떻게 상호 적용되는지 연구하였다. 결론적으로, 플레이어에게 공포심과 물입도를 더 증가시키는 구도를 제시했다. 즉 대각선 구도, 양대각선 구도, 역삼각 구도는 시각적인 요소와 같이 사용한다면 플레이어에게 물입도와 공포심을 유발할 수 있다. 향후 게임을 제작할 때 플레이어에게 공포감을 향상시킬 수 있는 구도를 제시하고자 하고 게임을 디자인할 때 공포감과 물입도를 증가시키는 구도를 활용할 것이다.

이 논문에서는 근래에 널리 사용되는 면진 장치인 폴리우레탄 스프링 복원형 디스크 받침의 동적거동에 영향을 미치는 구성재료의 인자에 대한 분석을 수행한 후, 그 결과를 이용하여 받침의 거동을 예측하여 거동 시험결과와 비교하였다. 여기서 동적거동에 영향을 미치는 인자로는 속도와 접촉압력에 따라 변하는 불소수지판(PTFE, PolyTetraFluoroEthylene, 폴리테트라플루오로에틸렌)의 마찰계수와 변형률에 따라 변화하는 폴리우레탄 스프링의 탄성계수가 고려되었다. 불소수지판은 W-PTFE virgin 제품을 사용하였고, 폴리우레탄 스프링은 직접 제작한 것을 사용하였다. 접촉압력, 속도에 따른 마찰계수 변화와 변형률에 따라 변하는 폴리우레탄 스프링의 탄성계수를 모사하는 식은 각각의 시험결과로부터 역추정 하여 사용하였다. 동특성 영향인자를 고려한 거동의 예측 결과는 동특성이 고려되지 않고 정적 인자만을 고려한 예측 결과보다 시험결과와 더 적절한 일치성을 보여주었다.

Objectives: The purpose is to prepare measures to effectively improve college life adaptation by identifying relevance between interpersonal relation disposition and college life adaptation, college life stress and college life adaptation for dental hygiene students. Methods: 375 dental hygiene students attending some local universities in Gyeonggi-do were sampled for convenience. The results of this study are as follows. Results: First, As a result of interpersonal relation disposition according to general characteristics, superiority-dominance tendencies were higher in first and third graders, in groups with grades above 4.0 and groups with lower subjective economic levels. And the stress of college life was high for second graders and students with lower grades than 2.0. Second, According to the correlation between factors, governance-dominance, independence-responsibility, sympathy-acceptance, sociable-friendliness, and ostentation-intoxication of interpersonal tendency factors had proportional relationship with college life adaptation, rebellion-distrust and college life stress had inverse relationship. Third, The results of multiple regression analyses to identify factors that affect college students' adaptation to college life were in the order of stress in college life, first grade, sociable-friendliness, second grade, rebellion-distrust. Conclusion: In order to improve college life adaptation, counseling and practical mediation programs should be developed and applied to effectively manage and control the negativity and positivity implied by interpersonal relationships and college life stress.

Obesity and overweight pose a significant public health problem, as they are associated with an elevated risk of metabolic syndrome (MetS). Several studies have shown that diet quality is associated with the development of MetS risk factors. Analyzing dietary patterns may be more helpful in determining the relationship between eating habits and chronic diseases compared to focusing on single foods or nutrients. In this study, our objective was to evaluate the association of food quality score (FQS) with risk factors for MetS in individuals with obesity and overweight. The participants in this cross-sectional study were 340 adults with overweight and obesity. Participants' food intake was measured using a Food Frequency Questionnaire, then the FQS was calculated. A fasting blood sample assessed serum glucose, triglycerides, total cholesterol (TC), high-density lipoprotein cholesterol, and serum insulin levels. Fat-free mass, height, basal metabolic rate, socio-economic score, and waist-to-hip ratio significantly differed among FQS tertiles. TC, systolic and diastolic blood pressure, and fasting blood glucose were significantly lower in the highest tertile of FQS. After multivariable adjustment, our results showed that individuals in the third tertile of FQS had reduced risk of higher levels of TC (odds ratio [OR], 0.982; 95% confidence interval [CI], 0.970-0.984) and higher levels of low-density lipoprotein cholesterol (OR, 0.974; 95% CI, 0.974-0.999). Our findings demonstrate an inverse relationship between diet quality, as measured by FQS, and MetS risk factors. However, further experimental and longitudinal investigations are warranted to elucidate the causal nature of this association.

This study was to clarify the variations in a marine ecosystem through examining the species composition of phytoplankton in the coastal water of Baegyado Island during winter. Water temperature, salinity, SS, NH$_4$-N, NO$_2$-N, NO$_3$-N and SiO$_2$-Si were significantly different and in inverse proportion to the chlorophyll a and species number according to stations and water depth. The total number of species was 88, composed of 94% Bacillariophyceae, 3.4% Chrysophyceae, 2.2% Dinophyceae and 1.1% Euglenophyceae. The dominant species were Rhizosolenia setigera, Skeletonema costatum and Stephanopyxis palmeriana. The maximum of standing crops was $5,450cells{\cdot}ml^(-1)$, while the minimum was $1,700cells{\cdot}ml^(-1)$. The coastal water was influenced with two water bodies which had characteristics of low water temperature - low salinity and high water temperature - high salinity.

Modal analysis of cracked cantilever composite beams, made of graphite-fibre reinforced polyamide, is studied. By using the finite element and component mode synthesis methods, a numeric model applicable to investigate the vibration of cracked composite beams is developed. In this new approach, from the crack section, the composite beam separated into two parts coupled by a flexibility matrix taking into account the interaction forces. These forces are derived from the fracture mechanics theory as the inverse of the compliance matrix calculated with the proper stress intensity factors and strain energy release rate expressions. Numerical results are obtained for modal analysis of composite beams with a transverse non-propagating open crack, addressing the effects of the location and depth of the crack, and the volume fraction and orientation of the fibre on the natural frequencies and mode shapes. By means of modal data, the position and dimension of the defect can be found. The results of the study confirmed that presented method is suitable for the vibration analysis of cracked cantilever composite beams. Present technique can be easily extended to composite plates and shells.

In this research, the relationship between physical measurements and subjective evaluations of floor impact noise in apartment building was quantified by applying the neural network analysis due to its complex and nonlinear characteristics. The neural network analysis was undertaken by setting up L-value, inverse A index, Zwicker parameters and ACF/IACF factors, as input data, which came from the measurements at real suites of apartment building having various sound insulations. The subjective responses from the psychoacoustic experiments were extracted as output data. Then, the reliability of the quantitative prediction for the subjective loudness was evaluated.

Lubrication and cooling characteristics are the most important factors of elevated temperature forging lubricants. Usually adopted lubricants in warm forging processes are graphite, synthetic and emulsion lubricants. Most widely and effectively applied lubricants are graphite lubricants, but these have a lot of problems like tool corrosion and dusty environment. In this research, boronite lubricant is considered, because it is able to substitute for graphite. Hot ring compression test, cooling test and mass production test are performed to check the validity of new lubrication pigment.

The purpose of this study was to analyze the differences in the health status of the divorced population according to their income status and to explain the social mechanisms. By analyzing 287 midlife men and women divorced within the last 5 years, we found a strong inverse relationship between their health and income status: the low-income divorced group was more liable to depression and poor physical health. Lack of social connections and having less hope for remarriage after getting a divorce were main factors explaining health vulnerability of the low income group among divorced. Further details have been discussed.
