대기오염이 인체나 생태계에 대한 피해뿐만 아니라 재료나 구조물에 대한 부식을 통하여 재산상의 피해를 초래한다는 것은 명백한 사실이다. 인체나 생태계에 대한 피해가 오랜 기간에 걸쳐 발생하며 여러 인자가 복잡하게 관여하는 관계로 이 분야에 대한 많은 연구 결과를 접하기가 어려운 실정이다. 결국, 이는 대기오염에 대한 사회적 무관심 속에 환경분야 내에서도 행ㆍ재정적 우선순위에서 뒷전으로 밀려나고 있는 실정이다. (중략)

This study investigates critical fashion and discusses its critical messages, as it challenges the existing system of the fashion industry. This study reviews the literature on critical art and critical design and analyzes exhibition catalogs, magazines, and websites related to critical fashion practices. Thereupon, this study assumes the two distinctive messages of critical fashion design: materiality and experience, and the redefinition of the ideal body. First, materiality and experience pursues a change in perceptions of clothing materials by way of deconstructing clothes and exposing the process of production. This type of critical fashion breaks away from the traditional sartorial conventions and articulates new structures and experiences through dematerialization. Second, the redefinition of the ideal human body attempts to subvert the stereotypes of ideal beauty and introduce a variety of beauty in the human body. This type of critical design reconstructs the human body through transformation, expansion, and deconstruction and is often liberated from the dichotomy of gender norms.

The human physiological systems are so complex and irregular dynamics. Dynamics of peripheral blood vessel, in particular, have quite sensitive and complex. Before, the linear analytic method have been used to analyze the system. But, the method have many problems to predict the following results. In the other hand, the nonlinear analytic method, chaotic time series analysis method, is suitable for measuring complex, vary system. In this study, the scalar data of the blood flow of peripheral blood vessel of rabbits, in accordance with injection of glucose, was obtained and redefined as multi-dimensional vectors, with time-series analytic methods. This study also intended to confirm that the peripheral blood flow is chaotic dynamics and evaluate the availability of non-linear analytic method. As a result, the existing FFT, and mean could show the difference of blood flow of peripheral blood vessel by injection of glucose, but the nonlinear analytic method could show the definite difference. The hemodynamics is a chaotic phenomenon.

In this paper, we propose a methodology of generating a parametric segment model for human body using the Korean anthropometric data. The model is defined as an articulated body model consisted with 19 ellipsoid primitives. The primitives are joined at locations representing the physical joints of human body. A lot of previous researches have suggested methodologies of generating body models using the European or American anthropometric data, so that these models were inappropriate for engineering analyses and simulations in case of the Koreans. We defined a set of 35 body dimensions representing our segment model based on the anthropometric data of Koreans. Also we defined four key parameters of age, height, weight and waist circumference, and then we applied regression equations to associate the parameters to the aforementioned dimensions. As the results, we obtained the parametric human body segment models according to the various body types and the subject-specific models for a specific individual. The models in the various industries can be used as the base models for static and dynamic analysis considering the Koreans.

One of the future weapon systems is the individual smart weapon which has a structure mounted on the forearm of soldiers. The structure may cause injuries or affect the accuracy of fire due to its impact on joints when shooting. This paper proposes human-impact interaction modeling and a verification methodology in order to estimate the impact of fire applied to the forearm. For this purpose, a human musculoskeletal model was constructed and the joints' behavior in various shooting positions was simulated. In order to verify the simulation results, an impact testing device substituting the smart weapon was made and the experiment was performed on a real human body. This paper compares the simulation results performed under various impact conditions and the experimental values in terms of accuracy and introduces methods to complement them. The results of the study are expected to be a basis for a reliable human-impact interaction modeling, and smart individual weapon development.

가금산업은 국민소득 증가와 식생활의 서구화로 생산액과 소비량이 증가하여 우리 농업에서 매우 중요한 위치를 차지하고 있다. 그러나 세계 각지에서 나타난 고병원성 조류인플루엔자로 인하여 많은 경제적 피해가 발생하고 있으며, 질병의 인체감염으로 인간의 소중한 생명도 위협을 받고 있다. 우리나라의 경우도 예외가 아니어서 그동안 모두 3차례에 걸쳐 고병원성 조류인플루엔자가 발생하여 많은 피해를 입었다. 고병원성 조류인플루엔자의 발생으로 인한 경제적 피해는 가금생산농가에만 국한되는 것이 아니다. 질병 발생으로 인한 경제적 피해는 생산농가와 직간접적으로 연관된 사료업체, 부화업체, 가공업체, 유통업체, 외식업체, 및 기타 관련 산업에서 골고루 발생하며, 손실보전을 위한 정부의 재정지출 증가로도 이어진다. 이번 연구에서는 고병원성 조류인플루엔자(HPAI) 발생이 미치는 경제적 영향을 계측하고 이와 관련하여 현행 질병 방역체계의 개선 방향을 도출하였다. 근래 들어 고병원성 조류인플루엔자의 연중 발생 가능성이 우려되기 때문에 질병예방과 확산방지를 위한 방역체계의 검토에서 개선 방안에 이르기까지 포괄적으로 다루었다.

It has been reported that the femoral morphology has a major correlation to femoral neck fractures(FNF). Previous studies to analyze these correlations have relied on mechanical testing and finite element methods. However, these methods have not been widely applied to various femur samples and models. It is because of the availability of the samples from both patients and cadavers, and also of the geometric limitations in changing the shape of the models. In this study we analyzed femoral neck fractures using a parameterized femoral model that could provide flexibility in changing the geometry of the model for the wide applications of FNF analysis. With the parameterization a variety of models could be generated by changing four major dimensions: femoral head diameter(FHD), femoral neck diameter(FND), femoral neck length(FNL), and neck-shaft angle(NSA). We have performed FEA on the models to compute the stress distributions and reaction forces, and compare them with the data previously generated from mechanical testing. The analysis results indicate that the FND is significantly related with the FNF and the FHD is not significantly related with the FNF.

One of the most important characteristics in the seventh educational course is an enforcement of differentiated level curriculum. Therefore, development of various different level educational subjects is needed. A new chromatographic experimental kit which is helpful for middle school students to understand chromatographic principles is needed to correct some mistakes of chromatographic part within the 6th educational course's middle school textbook. In this research, a new thin layer chromatography(TLC) experimental kit for middle school students are developed by using acid-base indicator as samples and ethyl alcohol, ethylacetate, hexane as eluents. The kit is applied to two kinds of middle school student groups(general group & genius group) and two kinds of teacher groups(science teacher & non-science teacher) and an efficacy of the new chromatographic kits are evaluated through making up some questions.

Five cases of Diphyllobothrium latum infection were proved by collection of worms after treatment with bithionol, niclosamide or praziquantel, during 1975~1983. The patients were 4 males and one female aged 10~64 years residing in Seoul or Wando-gun, Chollanam-do, Korea. All of them remembered the history of eating several kinds of raw marine fish and 2 persons said they ate the raw mesh of perch, Lateolabrax japcnicus. Three amcnE them experienced abdominal pain, 2 natural discharge of a chain of segments, but none revealed any sign of anemia. The average egg size in stool varied $59~67{\times}41~48{\mu\textrm{m}}$ according to cases. The eggs were characterised by ovoid to elliptical shape, terminal operculum, and distinct abopercular protuberance. One naturally discharged segment (30cm) and 4 complete strobilae (320~680cm) with scolices obtained after treatments were examined. The morphological characters of proglottids such as rosette-form uterus with 3~6 loops, vaginal pore included in the cirrus sac, separated seminal vesicle from cirrus sac, etc. were all compatible with D. latum. These are the 7th~11th cases of D. latum infection proved by worms in Korea.

Creation of a human skeleton model and characterization of the variation in the bone shape are fundamentally important in many applications of biomechanics. In this paper, we present a parametric shape modeling method for femurs that is based on extracting the main parameter of variations of the femur shape from a 3D model database by using statistical shape analysis. For this shape analysis, principal component analysis (PCA) is used. Application of the PCA to 3D data requires bringing all the models in correspondence to each other. For this reason, anatomical landmarks are used for guiding the deformation of the template model to fit the 3D model data. After subsequent application of PCA to a set of femur models, we calculate the correlation between the dominant components of shape variability for a target population and the anatomical parameters of the femur shape. Finally, we provide tools for visualizing and creating the femur shape using the main parameter of femur shape variation.
