The purpose of this study was to clarity the concept of health insensitivity using Hybrid model, which consists of three phases： theoretical, empirical, and analytic. In the theoretical phase, the definitions of health insensitivity were searched in korean dictionary and examples used in the websites because the concept of health insensitivity has never been studied before. Two dimensions of health insensitivity emerged out from this investigation were cognitive and behavioral. And then a working definition of health insensitivity was established. The sub-concepts and related factors of health insensitivity were identified through the extensive reviews of the literature focusing on two dimensions of cognitive and behavioral. In the empirical phase, in order to obtain description of health insensitivity, face-to-face in-depth interviews were conducted with nine persons who are not related to professional health care. Grounded theory approach was applied to analyze these qualitative data. In the final analytic phase, theoretical results and empirical results were analyzed in the integrated way and a theoretical framework of health insensitivity was established. A refined definition of health insensitivity was that decreased health risk perception in cognitive dimension and conduction of the unhealthy behaviors in behavioral dimension. Sub-concepts of decreased health risk perception were optimistic bias and decreased general fear. Sub-concepts of unhealthy behavior were doing health threatening behavior and not doing desirable health behavior. The contact of health information was a causal condition of health insensitivity. Optimistic disposition, health locus of control, and avoidance coping style were intervening conditions of health insensitivity. Three types of health insensitivity were identified： unconcern or ignorance type, optimistic bias type, and cognitive dissonance type. Finally, The implications of these findings for further research and nursing practice are discussed.

Purpose: The aims of this study were to develope a structural model of health insensitivity and to verify the model of health insensitivity. Method: There were three theoretical variables in the hypothetical model. The endogenous variable was health insensitivity which is a concept including bluntness of health risk perception and unhealthy behavior. The exogenous variables were composed of personal factors and socio-cultural factors. In personal factors, neuroticism, external health locus of control, blunting style of information-seeking, deficit of self-efficacy, knowledge deficit related to health, health-related experience, age and education were included. Whereas socio-cultural factors include perceived group size of unhealthy behavior and stereotypes of unhealthy behavior. Result: Personal factors and sociocultural factors were significant in explanation of the health insensitivity. Relationship between personal factors and sociocultural factors was significant, too. However, the optimistic bias as part of health insensitivity was not supported by these data. GFI, AGFI and PGFI were .95, .92, .65, respectively. Therefore, this model was verified to be a good fit to the data and parsimonious. Conclusion: Nursing to change unhealthy behavior has focused on personal factors rather than sociocultural factors. Based on this result, however, the sociocultural factors should be considered as well.

Recently, the government tends to address the health policy as an economic logic. However, health policy must be priority to national health right than economic logic. Thus, in this paper analyzes the problems of telemedicine for telemedicine that are at issue in South Korea, based on this, and presents reasonable health policy directions for telemedicine. To amend the law and legislation the health policy and law, analyze the rationality, feasibility of law and sufficient review should be implemented. Comparing to the foreign which introduced telemedicine earlier, discussion on telemedicine in South Korea remains a long way to go and it is now beginning step. Therefore, it should not forget that the health policy of the government with crass insensitivity can bring great disaster. Above all, to the health care, the sufficient review and social consensus which can reduce the side-effects are priority.

Due to the development and expansion of industries and medical standards, the number of workers who handle organic solvents within hospitals is increasing. The authors in this study intended to investigate the actual conditions of the handling of the solvents and to encourage the recognition that the exposure to such solvents may be possible because of insensitivity to safety. In order to investigate the actual conditions of exposure of workers within hospitals, the experimental group included the three sections (Pathology department, Central Supply Room, and Operating Room), which handle organic solvents most frequently. Meanwhile, university interns were selected to be the control group. This study was conducted between May 1 to May 30, 2007, and urine was taken as samples. Hippuric acid, mandelic acid, methylhippuric acid, and phenylglyoxylic acid were analyzed through gas chromatography, and a total of 52 subjects of the experimental and the control groups were performed of the analysis. As for the results of the analysis of the experimental group, the exposure to benzene was $42.27{\pm}3.70mg/g$ creatinine, that of xylene was $1.30{\pm}0.18g/g$ creatinine, and that of toluene was $2.36{\pm}0.24g/g$ creatinine. Meanwhile, the results of the analysis of the control group showed that the exposure to benzene was $15.54{\pm}2.85mg/g$ creatinine, that of xylene was $0.52{\pm}0.02g/g$ creatinine, and that of toluene was $0.85{\pm}0.20g/g$ creatinine. The amount of exposure to benzene, xylene, and toluene was shown to be under the maximum permitted level, but as for Pathology department, it was required to educate on working conditions, to educate workers on prevention management about their health, and to install fume hood and exhaust system to improve the environments.

대부분의 건설 재해는 공사장 안전수칙을 지키지 않거나 복장 및 보호장비 미착용, 안전 불감증 및 근로자의 건강 등의 인재로 분석된다. 이러한 건설 재해 예방을 위해서는 현장관리직이 근로자의 건강을 점검할 필요성이 있으나 매 시간 근로자의 상태를 확인하기는 어려운 실정이다. 따라서, 본 논문에서는 단순한 보호구 기능에서 벗어나 근로자의 산소포화도와 맥박 수를 체크하여 자동으로 건강 상태를 파악할 수 있는 디지털 안전모의 설계를 제안하였다.

Oil pollution seriously endangers the biological environment and human health. Due to the diversity of oils and the complexity of oil composition, it is of great significance to identify the oil contaminants. The 3-D fluorescence spectrum combined with a second order correction algorithm was adopted to measure an oil mixture with overlapped fluorescence spectra. The self-weighted alternating trilinear decomposition (SWATLD) is a kind of second order correction, which has developed rapidly in recent years. Micellar solutions of #0 diesel, #93 gasoline and ordinary kerosene in different concentrations were made up. The 3-D fluorescence spectra of the mixed oil solutions were measured by a FLS920 fluorescence spectrometer. The SWATLD algorithm was applied to decompose the spectrum data. The predict concentration and recovery rate obtained by the experiment show that the SWATLD algorithm has advantages of insensitivity to component number and high resolution for mixed oils.

A novel concept of transmissibility based on a wavelet transform for structural damage detection is presented in this paper. The main objective of the research was the development of a method for detecting slight damage at the incipient stage. As a vibration-based approach, the concept of transmissibility has attracted considerable interest because of its advantages and effectiveness in damage detection. However, like other vibration-based methods, transmissibility-based approaches suffer from insensitivity to slight local damage because of the regularity of the traditional Fourier transform. Therefore, the powerful signal processing techniques must be found to solve this problem. Wavelet transform that is able to capture subtle information in measured signals has received extensive attention in the field of damage detection in recent decades. In this paper, we first propose a novel transmissibility concept based on the wavelet transform. Outlier analysis was adopted to construct a damage detection algorithm with wavelet-based transmissibility. The feasibility of the proposed method was numerically investigated with a typical six-degrees-of-freedom spring-mass system, and comparative investigations were performed with a conventional transmissibility approach. The results demonstrate that the proposed transmissibility is more sensitive than conventional transmissibility, and the former is a promising tool for structural damage detection at the incipient stage.

One of the suitable structural damage detection methods using vibrational characteristics are damage-index-based methods. In this study, a damage index for identifying damages in plate structures using frequency response function (FRF) data has been provided. One of the significant challenges of identifying the damages in plate structures is high number of degrees of freedom resulting in decreased damage identifying accuracy. On the other hand, FRF data are of high volume and this dramatically decreases the computing speed and increases the memory necessary to store the data, which makes the use of this method difficult. In this study, FRF data are compressed using two-dimensional principal component analysis (2D-PCA), and then converted into damage index vectors. The damage indices, each of which represents a specific condition of intact or damaged structures are stored in a database. After computing damage index of structure with unknown damage and using algorithm of lookup tables, the structural damage including the severity and location of the damage will be identified. In this study, damage detection accuracy using the proposed damage index in square-shaped structural plates with dimensions of 3, 7 and 10 meters and with boundary conditions of four simply supported edges (4S), three clamped edges (3C), and four clamped edges (4C) under various single and multiple-element damage scenarios have been studied. Furthermore, in order to model uncertainties of measurement, insensitivity of this method to noises in the data measured by applying values of 5, 10, 15 and 20 percent of normal Gaussian noise to FRF values is discussed.

국내의 미세먼지 문제가 심각해짐에 따라 개인이 활동하는 주변공간의 미세먼지 농도를 알고자 하는 욕구 또한 증가하여 직접 미세먼지의 실시간 농도를 측정할 수 있는 휴대용 미세먼지측정센서에 대한 수요가 증가하고 있다. 그러나 시중에 판매되는 미세먼지 간이측정기는 정해진 인증기준 없이 제작 판매되고 있다. 본 연구에서는 최근 판매가 급증하고 있는 휴대용 미세먼지 측정센서의 농도값을 어느 정도 신뢰할 수 있는지와 이러한 센서들이 어떠한 경우에 활용될 수 있는 지에 대해 일반적인 시민의 입장에서 고찰할 필요가 있다고 판단하였다. 이를 위해, 1) 기기 간 상호비교 및 보다 정확한 장비와의 비교를 수행하고, 2) 휴대용 기기를 활용하여 미세먼지의 영향을 저감할 수 있는 방안들에 대한 검증실험을 수행해 보았다. 그 결과 휴대용센서들의 농도 절대값을 그대로 신뢰하기엔 문제가 있었지만, 그 재현성과 선형성은 실생활에서 활용되기에 유용하다고 판단되었다. 또한 휴대용 미세먼지 측정센서를 사용함으로써 사용자들은 자기 주변의 변화하는 미세먼지 농도에 대해 빠르게 인지하고 대처 할 수 있을 것으로 판단되어, 미세먼지 오염의 피해를 줄이는 데 활용할 수 있을 것이라 기대된다.
