  • Objectives: Although medical typologies based on indigenous biopsychological ideas have been described, their integrity has been questioned due to its theory-driven nature in categorization. Therefore, studies on the Sasang typology, a temperament-based traditional Korean medicine, are needed to examine whether it is possible to classify types of specific biopsychological profiles using data-driven analysis. Methods: Psychological measures of the Eastern Sasang Personality Questionnaire (SPQ) and Western NEO-Personality Inventory (NEO-PI) along with physical measures and Sasang types were acquired from 2,049 participants. Latent groups based on the SPQ and NEO-PI subscale scores were extracted using Latent Profile Analysis. Their psychosomatic features were then compared with those of Sasang types. Results: Three SPQ-based latent groups showed distinctive psychological and physical features consistent with those of Sasang types. However, four NEOPI-based latent groups presented only psychological features. Furthermore, SPQ-High and SPQ-Low latent groups demonstrated similar psychosomatic profiles to those of So-Yang and So-Eum Sasang types, respectively. Conclusions: This study illustrates that biopsychological profiles of Sasang types are supported by psychosomatic features of latent groups based on SPQ of Eastern psychology, signifying that the categorization of Sasang typology have acceptable validity and reliability.

  • In the present work, a main purpose is to propose a fuzzy integral-based aggregation framework to complementarily combine partial information due to lack of completeness. Based on Choquet integral (CI) viewed as monotone expectation, we take into account complementary, non-interactive, and substitutive aggregations of different sources of defective information. A CI-based system representing upper, conventional, and lower expectations is designed far handling three aggregation attitudes towards uncertain information. In particular, based on Choquet integrals for belief measure, probability measure, and plausibility measure, CI$\_$bi/-, CI$\_$pr/ and CI$\_$pl/-aggregator are constructed, respectively. To illustrate a validity of proposed aggregation framework, multiple matching systems are developed by combining three simple individual template-matching systems and tested under various image variations. Finally, compared to individual matchers as well as other traditional multiple matchers in terms of an accuracy rate, it is shown that a proposed CI-aggregator system, {CI$\_$bl/-aggregator, CI$\_$pl/-aggregator, Cl$\_$pl/-aggregator}, is likely to offer a potential framework for either enhancing completeness or for resolving conflict or for reducing uncertainty of partial information.

  • Objectives: The aim of this study is to critically review the health effects of not only direct exposure to biocide, but also indirect exposure to by-product hazardous agents generated through the use of biocide in metalworking operations. Methods: An extensive literature review was conducted of studies reporting on respiratory disease cases, particularly hypersensitivity pneumonitis (HP), in environments using water-soluble metalworking fluids (MWFs). Keyword search terms included 'metalworking fluids', 'machining fluids', 'metalworking operation' 'machining operation' and 'biocide', which were also used in combination. Additional articles were identified in references cited in the articles reviewed. Results: Several of the field, epidemiological and experimental studies reviewed assumed that the symptoms and signs typical of HP developed in machinists who handled water-soluble MWF could be caused by inhalation exposure to nontuberculous mycobacteria (NTM). Most NTM are known to be not only resistant to both biocide and disinfectant, but also to have acid-fast cell walls that are highly antigenic. The presence or persistence of the Mycobacterium species, referred to as NTM, in metalworking fluid-using operations may be caused by NTM contamination in either the natural water or tap water that is used to dilute the base oil and additives for water-soluble MWFs. This hypothesis that NTM contamination in water-soluble MWFs is a causative agent of HP has high biologic plausibility, such as antigenic property, hydrophobicity and small diameter (< 5 um). Conclusions: Aerosolized mycobacteria colonized from MWF are likely to be causing the HP. Inhalation exposure to mycobacteria should be considered as a possible cause for the development of HP.

양(quantity), 정도(degree), 가능세계 - 부사 '거의'의 어휘의미를 중심으로 - (Quantities, Degrees, and Possible Worlds - Lexical Semantics of Korean Adverb '거의(geoui)')

  • A Korean adverb '거의(geoui)' modifies predicates to generate complex predicates which have meanings of 'nearly' complete or typical properties of the modified predicates in quantities, degrees, and frequencies. The modified predicates 'complete' or 'typical' properties are referred counterfactually as standards for the generated predicates' meanings of deficiencies. These counterfactual standards can be formalized by a counterfactual conditional operator of the intensional semantics in Cresswell(1990). The deficiencies in the quantities, degrees, or frequencies of the properties can be expressed formally introducing a world-independent measure of comparison. The measure can be manufactured out of relations between intensional things at indices and their equivalence classes. The world-independent measure of comparison has a semantic structure under-specified in quantity, degree, and frequency, and seems very well-suited in describing lexical meaning of '거의(geoui)'. The lexical-semantic analysis of '거의(geoui)' shows explicitly the plausibility of the indispensable existence of the comparing measure which works across real and counterfactual worlds in natural language meaning. On the other hand, we examined Kim, young-hee(1985)'s proposal of a transition of quantificational meaning for Korean degree adverbs, where he tried to explain the quantificational meaning of Korean degree adverbs in general including '거의(geoui)' with several syntactic and semantic constraints of 'contextual deletion'. But it is shown that the quantificational meanings of the degree adverbs which Kim(1985) discussed are also explained better by their under-specified meanings in quantities, frequencies and degrees with the world-independent measure of comparison applied to their paradigmatic lexical constraint rather than Kim(1985)'s transition of meaning.

  • Pesticides are widely used to prevent loss of agricultural production but extensive exposure can induce health problems to pesticide operators. This study was performed to evaluate the health risk of highly produced pesticides used in fruit growing farm land by comparison of estimated exposure level with AOEL using KO-POEM program. AOEL was driven based on NOAEL of each pesticide evaluated by JMPR, EFSA or KRDA. In calculation of exposure level, types of formulation, dilution factors, spraying duration and motor type and exposure protection device were allocated according to actual condition of use. Dermal absorption rate was differently applied among EFSA default values (25% or 75%), general default value (10%) or real test result values to know the plausibility of default values and safety of pesticide to operators in outline. Twenty pesticide ingredients (fungicides and insecticides) were produced more than 30 tons per year, which were mancozeb, chlorothalonil, imidaclopirid and etc in order. Dermal absorption rates obtained from studies were various from 0.07 to 81% but mostly under 10%. The estimated exposure levels showed big differences more than 10 times higher when using EFSA default rate and up to 5 times higher when using general rate of 10% comparing using rates of test results. Mancozeb, chlorthalonil, diazinon and chlorpyrifos presented still higher exposure level than AOEL even when using test absorption rate from study, which suggests that re-evaluation of AOEL or dermal exposure absorption rate or strict management are required for health protection of operators who use those four pesticides in farm land.

  • 이 논문에서는 과학과 기술의 관계에 대해 기술은 응용 과학이라는 계층적 모델을 비판하고, 그 둘은 서로 독자적 영역을 가지면서 상호작용 한다는 상호작용 모델을 옹호한다. 상호작용은 모델에 의하면, 기술은 비록 과학으로부터 많은 지식을 빌려오지만 과학으로부터 오지않은 자신의 지식영역이 있다. 기술을 구성하는 여러 성분 중에서 특히 공학과학으로서의 기술에 중점을 두었고, 공학과학의 핵심을 설계에 있다는 것을 이야기 하고 공학설계의 특성에 관해 논의했다. 기술적 지식이 과학적 지식과 다른 것 중 하나는 기술적 지식의 변화 모델이 과학적 지식의 변화 모델과는 다르다는 것이다. 기술적 지식의 두 가지 중요한 모델인 쿤 방식의 모델과 변이-선택 모델을 논의하면서 두 모델의 약점을 이야기 했다. 과학과 기술의 상호과학적 지식의 작용은 '매개된 상호작용'이라는 모델을 제시했고 그 모델의 가능성에 대해 간단히 이야기 했다. 산업계의 연구는 과학과 기술 사이의 상호작용의 한 형태이다. 이 산업계의 연구를 통해서 과학-기술은 점점 구조화되고 자율성을 띈다. 과학자와 공학자는 인격적 주체자이기 보다는 단순히 산업연구 구조의 한 부분이 되어 버린다.

  • 플레이스는 단순한 물리적 공간보다는 확장된 의미이다. 따라서 장소를 대상으로 하는 모든 활동들은 이와 같이 다양한 관계 구조를 지닌 장소의 특성을 이해하고 핵심적으로 반영해야 한다. 최근에 주목받고 있는 플레이스 브랜딩도 예외는 아니다. 본 연구는 플레이스 브랜딩을 장소와 가치라는 차원에서 재검토하고, 이를 통하여 보다 체계적이고 구체적인 평가체계를 구축하고자 한다. 새로운 평가체계의 구축은 다음과 같은 문제 제기를 통해 얻고자 하는 목적을 충족하기 위함이다. 본 연구는 장소가치를 중심으로 하는 플레이스 브랜딩을 새롭게 정의하여 플레이스 브랜딩 시스템의 정확성과 보편성을 확보하고자 한다. 이를 통하여 작게는 역동적인 플레이스 브랜딩 활동에 일익하고, 크게는 도시디자인 관련 평가 모델로 활용될 수 있도록 한다는 점에서 연구의 의의가 있다.

  • 본 연구는 물리 기반의 자동차 애니에이션 기술을 연구하였으며, 일반인도 손쉽게 차량 애니에이션을 제작할 수 있도록 직관적인 저작도구를 제안하였다. 사용자가 직접 차량의 이동 경로 및 속도를 지정하면, 이동 경로의 방향적 특성에 기반한 시뮬레이션 구간 분할과 피드백 기반 주행 경로 탐색 기법을 통해 기존 연구보다 빠르고 정확한 주행 시뮬레이션을 수행하도록 하였다. 결과적으로 차선 변경 및 추월을 포함한 단순 주행 애니메이션뿐만 아니라 기존 관련 연구에는 없었던 차량 충돌 애니메이션 또한 제작할 수 있다. 아울러 차체 모델을 실제 차량과 유사하게 설계하였기 때문에, 제동 시 차량이 미세하게 혼들리는 현상이나 추돌 시 차량이 찌그러지는 현상 등 실제에 가까운 차량의 웅직임을 묘사할 수 있다.
