This study evaluated the thermoregulatory properties of functional thermal underwear (‘heating underwear’) in markets using a thermal manikin and human wear trials. One ordinary thermal underwear (ORD) and two functional thermal underwear (HEAT1 and HEAT2; manufactured goods, HEAT1: moisture absorbing heat release mechanism, HEAT2: heat storage, release mechanism) were chosen. Thermo-physiological and subjective responses were evaluated at an air temperature of 5.0±0.5oC and air humidity of 30±5%RH with five male subjects (21.6±1.3yr in age, 178.0±5.9cm in height, 68.2±5.9kg in body mass). Experimental conditions consisted of four ensembles that included winter clothes (Control: no underwear, ORD, HEAT1, HEAT2). Water-vapor resistance was greater in fabric of HEAT1 than others. The results were: 1) Total thermal insulation (IT) using a thermal manikin were not greater for HEAT1 (0.860clo) and HEAT 2 (0.873clo) than for ORD (0.886clo). 2) There were no significant differences in rectal temperature, mean skin temperature, heart rate and total body mass loss between the four conditions. Microclimate clothing temperature on the back was greater for ORD than for HEAT1 and HEAT2. Subjects felt more comfortable with HEAT1 than for others at rest. HEAT2 was higher in microclimate humidity when compared to other conditions. The results suggest that thermoregulatory properties of ‘heating underwear’ in market did not differ from those of ordinary thermal underwear in terms of total thermal insulation and thermoregulatory responses in a cold environment.

This study investigates quantitative wear training effects and involved 15 participants from a previous study (part 1) in May to September 2009. Before wear training, the subjects` rectal temperature, skin temperature, heart rate, blood pressure and local sweating were measured for 1 hour in a climate chamber (39±1℃, 65±5%RH, 0.3m/s) to evaluate heat tolerance. Subsequently, the subjects were divided into 3 groups that consisted of 5 participants. Group N (control-group) dressed the participants so that they felt comfortable (or cool), Group W and MW where participants underwent regular wear training for 10 weeks (5 days a week a total of 50 times), The intensity of the wear training for the participants of group MW was stronger than that for group W, A heat-tolerance experiment was performed after wear training, The results were as follows: 1, The participants of groups W and MW felt more comfortable after wear training than before wear training in the case of warmer TCL. However, no significant differences were observed before and after wear training for group N. 2. The heat tolerance of the participants of groups W and MW was higher after wear training than before wear training. However, no significant difference was noted in this regard for group N. 3. The results showed the wear training effect (based on quantitative guidelines). The results show that the predicted optimal temperature inside clothing can enhance heat tolerance.

Dewey의 경험과 Whitehead의 리듬의 특성고찰: 통합성과 그것의 교육적 의미

이효현 ( Hyo Hyun Lee ) 한국교육과정학회 2010 교육과정연구 Vol.28 No.1

Dewey와 Whitehead는 세계와 인간 경험에 대해 과정적 사유를 공유하는 과정 철학자로 알려져 있다. 이들은 교육의 중대한 관심사 중의 하나인 인식론적 문제에 있어서 인식 주체와 인식 대상을 분리하였던 기존의 인식론과 달리 인식 주체와 인식 대상의 상호작용과 관계에 주목하고 있다. 그리고 교육을 하나의 과정으로 본다는 점에 있어서 공통점을 보여주고 있다. 이렇게 세계관, 인식론, 교육적 사유에 있어서 유사한 관점을 가지고 있다면 그들의 교육적 사유의 핵심 개념인 Dewey의 `경험`과 Whitehead의 `리듬`에 어떤 공통적인 특성이 있을 것이라고 가정할 수 있다. 본 연구에서는 이러한 가정을 토대로 하여 Dewey의 경험과 Whitehead의 리듬의 개념에 내재된 통합성의 특성에 대해 각각 고찰하고, 이 특성의 교육적 의미를 밝히고자 한다. 먼저 Dewey의 경험의 개념과 경험의 개념에 내재된 지적 성장의 통합성, 자유와 통제의 통합성, 학습자의 현재 경험과 지식의 통합성에 대해 고찰하였다. 그런 다음 Whitehead의 리듬의 개념과 리듬의 개념에 내재된 지적 성장의 통합성, 자유와 규율의 통합성, 삶과 지식의 통합성에 대해 고찰하였다. 마지막으로 Dewey의 경험의 통합성과 Whitehead의 리듬의 통합성이 교육 방법, 교육 내용의 선정과 조직, 그리고 교육 목적을 이해하는 데에 주는 시사점에 대해 고찰하였다. The aim of the study is to clarify the concept of integrity and to find out its educational implications in Dewey`s Experience and Whitehead`s Rhythm. Dewey and Whitehead share many ideas about world view, epistemological concern, and educational thought. Then it is possible to suppose that there would be some common characteristics between their most general educational ideas, that is, experience and rhythm. On the base of this supposition, the followings are investigated. Firstly, the concept of Dewey`s experience and its general characteristics were investigated in connection with the integration of reflective thinking, freedom and social control, and learner`s present experience and subject-matter. Then, the concept of Whitehead`s rhythm and its general characteristics were investigated in connection with the integration of intellectual growth, freedom and discipline, and learner`s present life and knowledge. Finally, it was clarified what implications the general characteristics of integrity in Dewey`s experience and Whitehead`s rhythm have for understanding teaching and learning method, selecting and organizing subject-matter, and understanding educational aim.

This study suggests quantitative guidelines for inside clothing temperatures to improve the heat tolerance of 20``s females in summer. First, the inside clothing temperatures (Tcl) of each subject was measured in daily use. The subjects were asked to record subjective thermal sensations, clothing items worn, clothing weight, and activities during an experiment designed to determine the comfort zone of Tcl. In a thermally neutral state, the comfort zone of Tcl was decided on a mean value Tcl±1σ. Second, the subjects were asked to wear clothing that would enable them to feel ``slightly warm but still comfortable``. The rest of the processes were the same as previous steps that were designed to understand the way and degree of clothing control. The comfort zone of Tcl was decided in the same manner as the previous step. The two comfort zones were combined and named the combined comfort zone of the definitive comfort zone. The results were as follows: 1. Thermally comfortable Tcl, Hcl were 34.0±1.1℃, 40±9%RH and the thermally comfortable ambient climate was 25.0±1.6℃, 53±7%RH. 2. When subjects were asked to wear ``slightly warm but still comfortable``, there were difference in thermally comfortable Tcl, clothing weight and clothing layer by subject. 3. In this study, the optimal Tcl was decided on the mid-point of the definitive comfort zone of Tcl.

이 연구의 목적은 학습자의 현재 경험의 특성과 그것의 교육적 의미를 고찰하는 데에 있다. 이를 위해 Ⅱ장에서는 Whitehead의 유기체 철학과 그의 교육에 대한 사유에 나타나는 유기체의 특성을 고찰하였다. 그 결과 유기체는 자기 초월적 주체, 관계적 존재, 창조적 존재의 성격을 지니고 있음을 밝혔다. 그런 다음 학습자의 현재 경험의 특성으로 현재 경험의 총체성, 현재 경험의 정서성, 현재 경험의 잠재성에 대하여 고찰하였다. Ⅲ장에서는 Ⅱ장에서 고찰한 내용을 토대로 유기체인 학습자의 현재 경험이 교육 현상과 교육 활동을 이해하는 데에 주는 시사점에 대하여 고찰하였다. 먼저 학습자의 현재 경험은 학교 교육 현상과 교육 활동을 이해하고자 할 때 가장 먼저 고려해야할 사항임을 밝혔다. 그리고 학습자의 현재 경험은 교육목적, 교육내용의 조직과 선택, 교육방법, 그리고 평가방법을 결정하는 준거로 활용될 수 있음을 밝혔다. 마지막으로 학습자의 현재 경험은 실제 교육 상황에서 교육과정을 적용하고 변형하는 준거로 활용될 수 있음을 밝혔다. The aim of the study was to clarify the concept of the present experience of learner and its educational implication in Whitehead organic philosophy and his educational idea. To begin with, to find out the concept of the present experience of learner, the qualities of learner as a organism were investigated. and it was investigated that the present experience of learner had there qualities, that is, the whole, the ambiguous feeling, and the potentiality. Then the educational implication of the present of lerner`s implication were investigated. The following were the results. Firstly. the present experience of learner should be a priority in understanding educational event. Secondly, the present experience of learner can be used as a judging criteria in deciding educational objective, teaching material, teaching and learning method, and educational evaluation. Finally, the present experience of learner can be used as a criteria in carrying and transforming curriculum.

The present study was aimed to evaluate the mobility and physiological performance of the current Korean Navy summer uniform with a newly developed Navy summer uniform. Eight young males (22.4±2.4 yr in age) participated in the following investigations: simulated-naval tasks at Tair 30℃ and posture analyses at Tair 22℃. The simulated naval tasks consisted of the following five activities sequentially: passing through a low ceiling and an arrow aisle, going up/down stairs, going up/down a straight ladder, walking at 5.5 km·h<SUP>-1</SUP> on a treadmill, and laying down/standing on a portable bed. The results were as follows. No differences were found in blood lactate acid, total sweat rate, and completion time between the old and new uniforms, while clothing microclimate temperature and humidity on the back was greater for the old uniform than for the newly developed uniform (p<.05). For humidity sensation, subjects felt more humid when wearing the old uniform than wearing the new uniform (p<.05). As for the posture test and interviews, the old uniform was evaluated as more uncomfortable and irritating than the new uniform, especially for the upper arms, waist, and front thighs. These results suggest that design requirements to improve the mobility and performance of the old uniform are to improve breathability on the upper back of the shirts, to leave the shirts hanging out over the pants, to enlarge the thigh parts and narrow down the bottom of trousers, and to use elastic materials on the elbow and knee parts.

The purpose of this study was to investigate changes in thermal adaptive properties for the elderly haenyeos by a questionnaire and a local cold tolerance test. We carried out an one-on-one questionnaire in Jeju, Korea. A total of 112 hanyeos (68±8 yr in age) and 177 haenyeos (66±8 yr) participated in the survey. The questionnaire in the main survey consisted of 37 questions related to demographic characteristics (3 questions), diving practices and diving suits (12 questions), and behavioral temperature regulation and thermal tolerance (22 questions). As a local cold tolerance test, finger cold-induced vasodilation (CIVD) at 4℃ were measured during 4℃ cold water immersion for old haenyeo (N=3) and young female (N=12) groups. The results showed that the elderly haenyeos felt warmer in summer and colder in winter when compared to their own twenties. However, haenyeos considered themselves as the one who sweats more and being more sensitive to heat in summer compared to the similar aged of older non-women divers, whilst they perceived being less sensitive to cold than other older non-women divers. For the finger CIVD test, the eldelry haenyeo group showed higher minimum finger temperature and faster peak time which indicate greater local cold tolerance when compared to the young female group. In summary, the elderly haenyeos identified themselves to have weaker cold tolerance compared to their twenties, but greater self-identified cold tolerance than other aged nonwomen divers, and greater local cold tolerance than young females.
