15Cr-1Mo base oxide dispersion strengthened (ODS) steel which is considered to be as a promising candidate for high- temperature components in nuclear fusion and fission systems because of its excellent high temperature strength, corrosion and radiation resistance was fabricated by using mechanical alloying, hot isostatic pressing and hot rolling. Torsion tests were performed at room temperature, leading to two different shear strain routes in the forward and reverse directions. In this study, microstructure evolution of the ODS steel during simple shearing was investigated. Fine grained microstructure and a cell structure of dislocation with low angle boundaries were characterized with shear strain in the shear deformed region by electron backscattered diffraction (EBSD). Grain refinement with shear strain resulted in an increase in hardness. After the forward-reverse torsion, the hardness value was measured to be higher than that of the forward torsion only with an identical shear strain amount, suggesting that new dislocation cell structures inside the grain were generated, thus resulting in a larger strengthening of the steel.

이 연구의 목적은 대중의 체력을 관리해온 전문 지식인 집단인 건강운동관리사 집단의 전문성을 둘러싸고 만들어지고 있는 사회적 경계를 드러내는 것이다. 지난 70여년의 세월 동안 한국 사회에서 체력의 사회적 개념은 공공 보건 구호의 캐치프레이즈인 ‘체력은 국력’에서, 개인의 삶의 역량과 기술을 반영하는 ‘생존 체력’의 구호로 변모해왔다. 이 연구는 변화해온 체력의 개념과 체력 관리라는 영역에서 전문화의 시도가 어떻게 이루어졌으며, 해당 직역의 전문성이 어떠한 사회적 도전에 직면해 있는지 드러낼 것이다. 이를 위해 본 연구에서는 대중의 신체를 관리하는 유일한 정부 공인 집단인 운동처방사(현, 건강운동관리사)가 어떠한 사회적 환경에서 등장하여 어떠한 제도를 통해 자신을 형성했는지 추적하는 것을 통해, 운동처방사가 기반해 왔던 학문적 지식장의 변화, 제도적 변화, 그러한 변화 안에서 겪어야 했던 갈등이 어떻게 건강운동관리사의 변화를 견인했는지 탐색한다. 이어서 그 갈등을 과학기술학(STS: science and technology studies)의 전문성에 관한 논의를 통해 고찰함으로써, 기존의 체육학 학술장에서 추구해 온 ‘자기 완성’으로서의 전문성 반성만으로는 현재의 건강운동관리사가 처한 사회적 갈등을 돌파할 수 없으며, 의학과 체육학의 경계에 존재하고 있는 건강운동관리사의 전문성은 체력관리 관련 제도를 둘러싼 내·외부의 동원을 모두 포함해 동시적으로 산출되는 것임을 지적할 것이다. This study aims to reveal and unfold the social boundary made around the expertise of sports/exercise specialist, a group of experts who have managed the physical fitness of the public. Over the past 70 years, the social concept of physical fitness in Korean society has been transformed. The catchphrase of ‘physical strength is national power’ has changed to the slogan of ‘physical stamina for survival’, reflecting increased the social interests in individual capabilities and skills. This study investigates how the attempts of expertification have been made and un-made around physical fitness as an ever-changing notion. Firstly, the study follows the pathways through which exercise prescriptors(currently, sports/exercise specialists) have formed as an institutionalized group. Secondly, the study examines how sports/exercise specialists as a group have been transformed in response to the conflicts stemming from changes in academic fields and regulatory frameworks. Lastly, the study discusses the aforementioned conflicts through insights obtained from science and technology studies (STS) literature on expertise. The study concludes that expertise of sports/exercise specialists, who currently occupy the boundary between medicine and sports medicine, is to be produced both inside and outside of the institutionalized system of managing physical fitness. In order to settle the conflicts emerging around the expertise of sports/exercise specialists, the issue of expert-making needs to be seen as a social problem, which cannot be sufficiently resolved if conceptualized as individual self-completion.

경찰 체력검정의 역사적 변화: 남녀 차이의 사회적 논란과 과학적 합리성

진현주 ( Jin Hyunju ),김효민 ( Hyomin Kim ) 한국체육학회 2020 한국체육학회지 Vol.59 No.2

체력은 체육학에서 명실공히 주요한 연구 주제이다. 체력에 관한 다양한 연구 중에서도 체력검정, 즉 신체를 측정하고 신체가 가진 역량을 평가하는 작업에 대한 연구는 체육학 내에서 가장 오래된 역사를 지니고 있다. 그러나 최근 한국 사회에서 경찰, 군대 등에 지원하는 남녀의 체력검정 기준의 차이를 둘러싼 논란은, 기존의 연구 성과에 따라 ‘검정’될 수 있는 체력이 있다는 인식을 대중이 널리 공유하는 것과는 별개로, 체력검정 기준에 대한 보편적 합의가 아직 사회적으로 형성되지 않았음을 시사하고 있다. 이에 본 논문에서는 체력을 측정하는 방법의 학술적, 사회적 변화 양상을 추적하여 체력검정 기준의 합리성에 대한 역사적 고찰을 시도하였다. 먼저 기존에 형성되어온 체력의 학술적 개념의 변화에 대한 조사를 통해 체력 개념의 다양한 정의와 의미를 탐색한 후, 경찰공무원의 체력검정을 중심으로 신체 검정의 기준과 관점의 변화를 살펴, 기존 체력검정의 합리성을 평가해온 기준을 분석하고 그 합리성이 의미하는 바를 문제화(problematization)하고자 하였다. 이 연구는 특정 직군의 체력검정 기준으로 인해 제기된 사회적 논란을 통해 그동안 당연하게 합리적 근거를 가진 것으로 받아들여져 왔던 ‘체력’, 그리고 그것이 객관적으로 ‘검정’될 수 있다는 관념이 실상은 고정된 진리가 아니라 다양한 네트워크를 통해 형성되고 도전받아 변화하는 유동적 열린 체계임을 지적할 것이다. Physical fitness is a major research topic in sport studies. Among diverse sub-topics of physical fitness, the physical fitness test, that is the measurement and evaluation of physical fitness, has the longest history as a research area. However, the recent controversy in Korea over gender-normed physical fitness requirements in army or police recruitment indicates that despite widely shared common understanding of physical fitness that can be “tested” in accordance with research outcomes of sport studies, there is still no general agreement on the legitimate standards for physical fitness test. By tracking the relevant academic and social discussions, this paper presented a historical review of the logical rationale provided for physical fitness tests. This paper first explored definitions and meanings of physical fitness established in sport studies; then it examined the historical changes in standards for and perspectives upon occupational physical fitness tests for Korean police officers. By so doing, this paper analyzed and problematized how certain physical fitness tests have so far been (un)-successfully justified as rational methods of measurement. Through the investigation of social debates over what count as legitimate standards for occupational physical fitness tests, we demonstrated that the concept of “physical fitness” and the notion that it can be “tested” with an objective measure is not a fixed reality based upon well-founded rationales but a porous and flexible system that is continuously constructed by heterogeneous networks while facing challenges.

Sparganosis is a kind of parasitic skin disease caused by sparganum, the plerocercoid larvae of the taper worm of the genus Spirometra. Sparganosis usually manifests as migrating or fixed subcutaneous nodules; therefore, it should be differentiated from lipoma, cysts, and cutaneous malignancies. Although the final diagnosis of sparganosis in humans depends on the identification of the worm in an infected tissue, suspicion for the presence of the parasite and careful history taking are important before making the diagnosis. However, it might be difficult for a clinician to suspect the existence of sparganosis because the incidence of this disease is extremely low. Therefore, an effective method for differentiating sparganosis from other skin disorders is needed. We suggest that ultrasonography could be an answer to this problem, on the basis of our experience of a case of cutaneous sparganosis in a 65-yearold woman showing very characteristic ultrasonographic findings.

Carcinoma of the uterine cervix is a common malignancy for women in Korea. It frequently metastasizes to the lungs, bone, or liver, but cutaneous metastasis is rare, with a reported incidence of only 1.3%. In cases of cutaneous metastasis, the lesions present in the forms of nodules, ulcers, or plaques, and are generally located in the abdominal wall, vulva, anterior chest wall, lower extremities, and upper extremities. Here, we describe a case of a 64-year-old woman diagnosed with cutaneous metastases from squamous cell carcinoma of the uterine cervix on both flanks, lower abdominal wall, and both inguinal areas, three years after receiving chemoradiation therapy. At presentation, the primary carcinoma had been resolved completely. Histological and immunohistochemical findings revealed intact epidermis and infiltration of tumor cells in the dermis, which showed positivity for cytokeratin 5/6, cytokeratin 7, and tumor protein 63, consistent with metastatic squamous cell carcinoma of the uterine cervix.

Purpose: Studies on craving may be conducted for exercise addiction, which is one part of behavioral addiction, just like many studies that focused on craving for behavioral addiction. Hence, the objective of this study is to develop and validate scale that can measure craving for exercise. Methods: To develop the scale to measure the craving for exercise, 37 preliminary questionnaire items were selected based on the literature review and previous studies. Adult men and women who exercise more than 30 minutes once a week were set as the population. For sampling, survey focused on 300 adults full aged above 19 and below 80 through purposed cluster. The survey was performed two times. Analysis of questions and exploratory factors was performed based on data collected in the 1st survey. Analysis of confirmatory factor sand verification of cross/convergent validity were performed based on data collected in the 2nd survey. Results: First, measurement tools of exercise craving were structured into eight questions on single factors based on analysis of exploratory factors. Second, measurement tools of exercise craving deliver reliability. Third, measurement tools of exercise craving have structural validity based on analysis of confirmatory factors. Fourth, measurement tools of exercise craving verified their convergent/predictive validity. Conclusion: This study suggested the possibility of conducting studies on craving in exercise psychology studies, as well, at a time when no studies on exercise craving were conducted and developed an scale with which exercise craving can be measured in a reliable and valid manner. These all serve as new data applicable to future studies on exercise psychology.

The purpose of this research was to identify the impact of the degree of mania for skiing on exercise addiction and wellness, having classified the groups involving ski manias according to their degree of mania. To accomplish the purpose, 350 participants were sampled by means of stratified cluster random sampling method. Only 295 questionnaires were statistically processed, while 55 questionnaires were excluded because their respondents failed to complete instrument and judged insincere in filling out questionnaire. To analyze the data collected, statistical techniques, such as Descriptive Statistics, Reliability Analysis and one-way ANOVA were used, and as for difference verification between individual groups in relation to significant results, Scheffe's post hoc test was conducted. Through the above research methods and procedures as intended in this research work, the following conclusions were derived from the results of verification of research hypothesis concerned with the impact of degree of mania on exercise addiction and wellness. Results from analysis showed that the degree of mania for skiing impacted on addiction to exercise. The higher the level of mania was, the higher level of exercise addiction was exhibited. And that there were statistically significant differences between the degree of mania for skiing and addiction to exercise.

The purpose of this research was to closely examine whether or not sport club activities have effects on sensation seeking on the subject of university students. In order to achieve such objective, total 500 sample students were selected using stratified cluster sampling method. Among all, 250 were enrolled in sport clubs within the universities and another 250 were not enrolled in any clubs including sport clubs. Among the total 500 respondents, except 48 with partially missing answers and 60 non-participants, the data of total 393 respondents including 202 who were enrolled in sport clubs and 190 who were not enrolled in any sport clubs were finally analyzed. To analyze the data collected, statistical techniques, such as Descriptive Statistics, Reliability Analysis, Independent-sample t-test, and one-way ANOVA were used, and as for difference verification between individual groups in relation to significant results, Scheffe's post hoc test was conducted. As a result of examination on whether or not sport club activities have effects on sensation seeking through the method and procedures for the above objective, it was concluded as following: First, the difference of sensation seeking depending on whether or not sport club activities have effects on sensation seeking shows that the participant group has the higher average and that statistically significant differences were found in all lower factors. Second, the analysis on how background variables of participation in sport club activities influence on sensation seeking presents that experiences and frequency of activities do not have an influence. The level of technique shows a statically significant difference only in sensation seeking and fatigue sensitiveness of lower factors.
