Recent increases of asthma and allergies in childhood made the need for a standardized approach to international and regional comparisons of their prevalence and severity. To address these issues, 'International Study of Asthma and Allergies in Childhood (ISAAC)' is currently underway. In Korea, 'Nationwide Study of Asthma and Allergies in Korean Children' began in 1995 according to ISAAC protocol. ISAAC written and video questionnaires were used in this survey, but their reliability and validity were not evaluated properly yet. In this study, our aim was to evaluate the reliability and validity of two kinds of questionnaires and their usefulness in international and regional comparisons. The test and retest of two questionniares were completed by male(n=110) and female(n=111) middle school students with two and three weeks interval each. Kappa(or weighted kappa) were calculated from each questions and validity coefficients were estimated from those statistics. In Korean version of written questionnaire, the questions for allergic rhinitis, atopic dermatitis, allergic conjunctivitis, and food allergy proved to have high kappa values (or weighted kappa values) and validity coefficients and they can be used in further studies without any correction. But some questions about asthma(especially nocturnal cough, wheezing in exercise, and severe asthma) and drug allergy need to be revised for better under-standing to study subjects. Video questionnaire has the same degree of reliability and validity when compared to written questionnaire and this is the unexpected result. Accordingly, it also need to be revised to overcome the racial and cultural differences of the study subjects. In conclusion, the Korean version of written and video questionnaires may be considered to be useful methods in international and regional comparisons of asthma and allergic diseases in childhood after correction of some questions.

Objectives: To compare the health behaviors of widowed women with those of currently married women. Methods: We randomly sampled the subjects from the Jeollanamdo Resident Registration Data and we then selected 2,331 widowed women and 4,775 married women. Well-trained examiners measured the height, weight, blood pressure and abdomen circumference, and the women were interviewed with using a questionnaire. Logistic regression analysis was used to estimate the odds ratios(OR) of the two groups. Results: The smoking rate (OR=2.46; 95% confidence interval [CI]1.65, 3.66) was significantly higher for the widowed women. On the contrary, the awareness rate of a smoking cessation campaign (OR=0.80; 95% CI=0.70, 0.92), a quit tobacco telephone line (OR=0.73; 95% CI =0.61, 0.88) and a quit smoking clinic (OR=0.74; 95% CI=0.62, 0.89) were lower for the widowed women. The rate of receiving a health exam (OR=0.80; 95% CI=0.70, 0.91), the rate of undergoing gastric cancer screening (OR=0.77; 95% CI=0.68, 0.88), breast cancer screening (OR=0.79; 95% CI=0.69, 0.89), cervix cancer screening in the last 2 years (OR=0.81; 95% CI=0.71, 0.92), colon cancer screening in the last 5 years (OR=0.74; 95% CI=0.63, 0.87) were significantly lower for the widowed women. Conclusions: This study revealed that the health behaviors are significantly different between the widowed women and the married women. To improve the health behaviors of the widowed women, further study and research that will investigate the socioeconomic and environmental factors that affect the health behaviors of widowed women will be needed.

Basal cell carcinomas usually arise from the epidermis and show some epidermal connections. It is very unusual that basal celi carcinomas occur as subderrnal mass without epidermal connections. A 51 year-old female h;d an asymptomatic skin colored indurated plaque with linear old scar on the left side of nose fcr about 20 years. She had had a tumor that supposed to be a epidermal cyst, on the same site and the lesion was excised about 20 years ago. We performed the punch biopsy on her first visit which revealed hypertrophic scar. She was treated with intralesional injection of triamcinolone acetonide to reduce the size of hypertrophic scar. However, the lesion had not been reduced. She underwent the surgery to remove the scar at plastic surgery and the excisional biopsy showed a subdermal basal cell carcinoma. We recommend that the newly developed skin tumor in the pre-excised region should be required excisional biopsy instead of punch and close observation (KOfean J Dermatol 1997;35(5): 1036-1039)

Metaphor as Statement and Topos of Discourse and Power

최성우(Seong-Woo Choi) 한국비평이론학회 2022 비평과이론 Vol.27 No.1

본 연구의 목적은 담론의 언표와 토포이(topoi)로서 은유의 역할을 고찰하는 것으로, 은유를 단순히 장식적 장치나 인지의 방식으로만 바라보지 않고 수사학적 관점에서 담론의 창의적이고 비판적인 구성요소로 접근한다. 수사학 분야에서 은유는 전통적으로 대체 및 비교의 시각에서 연구되어 왔지만, 20세기를 지나며 은유는 발화자와 청자가 세계를 이해하고 그들이 생각하고 행동하는 방식을 형성하기 위한 인지의 도구로서 받아들여졌다. 그러나 인간은 세계에 대한 유사한 인식을 공유하고 물리적 경험을 기반으로 동일한 은유를 생성할지라도 그들이 처한 사회 문화적 환경과 정치적 현실이 다르기 때문에 유사하거나 동일한 은유를 가지고도 다른 수사학/담론들을 구성한다. 은유는 한 개념을 다른 개념으로 설명하는 언표이며 서로 같지 않은 두 개념 사이의 관계를 보여준다. 또한 은유가 하나의 언표로서 기능하려면 은유는 발화자와 청자가 서로의 이해를 공유하는 공통의 장소여야 한다. 따라서 지배적 담론에 반기를 들거나 저항하기 위해서는 은유가 담론의 언표와 토포이로 작동한다는 사실을 깨닫고 이를 창조적이고 비판적으로 사용하며 은유의 형성과정을 이해하는 것이 중요하다. 사람들이 사용하는 은유를 바꾸면 그 시대의 진리도 바뀌고 결과적으로 현실도 바뀔 수 있다. 이러한 방식으로 은유는 지배 담론에 도전할 수 있고 현실을 개혁하는 힘으로 사용될 수 있다. This study aims to consider the roles of metaphor as statements of discourse and as topoi, approaching it not merely as ornamental device or cognitive mode but as a creative and critical component of discourse from a rhetorical angle. In the field of rhetoric, metaphor has traditionally been studied from substitution and comparison views, but in the twentieth century, metaphor is defined as a cognitive tool used for rhetors and audiences to understand the world and to shape the way they think and act. However, although humans share a similar cognition of the world and produce the same metaphors based on physical experiences, they construct different rhetoric or discourses with the similar or same metaphors because their sociocultural environment and political realities are different. A metaphor is a statement that one concept is another, showing a relationship between two things that are not alike. In order to function as a statement, metaphor should be a common place where a rhetor and audience share understanding with each other. Therefore, in order to oppose a dominant discourse, it is important to know and use metaphors as topoi and statements of the discourse and the process of their formation. If the people change the metaphors, the truths change, and consequently, reality can change. In this way, metaphors can challenge the dominant discourse and can be used as power to reform reality.

The purpose of the study was to examine the effects of the 『Playing School』program applied for elementary school students’ cognitive and metacognitive strategy development in Korea. The research questions were as follows: 1) How do the Playing School program influence on elementary school students’ cognitive strategy including rehearsal, elaboration, and organization ability, 2) How do the Playing School program influence on elementary school students’ metacognitive strategy including planning, monitoring, and regulation ability, and 3) What are the satisfaction degree of the elementary students for the program? The participants of the study were 181 elementary school students in Seoul, Korea. They took self-directed learning ability measurement tests developed by CK Instructional Development Institute of Soongsil University as the pre- and post-test. The study collected participants’ cognitive and metacognitive strategy scores from the tests and used dependent sample t-test for the analysis. The participants’ satisfaction degree was analyzed by descriptive analysis. The research results were as follows. First, the increase of the participants’ cognitive strategies including rehearsal, elaboration, and organization ability were all statistically significant. Secondly, the increase of the participants’ metacognitive strategies including planning, monitoring, and regulation ability were all statistically significant. Finally, the participants’ satisfaction degree was very positive, showing the average from 4.21 to 4.67, and 95% of satisfaction with the program and 96% of intention of taking the follow-up program. In conclusion, The playing school program showed positive effects for development of elementary school students’ cognitive and metacognitive strategies. And we expect that the effects of the program will be more enhanced when the learning strategies and program operation strategies are utilized in other subject matter activities by the classroom teachers.

At present, flux or metal cored wires are widely used in iron-based materials for flux cored arc welding in order to reduce the cost of welding production. However, the development of flux or metal cored wire for titanium materials, which are widely used in the petrochemical, power plant and marine vessel fields, has not been done yet, and development is required. In this study, manufacturing process of titanium alloys flux-metal cored wire for gas tungsten arc welding was investigated by FEM simulation and experimental analysis. FEM simulation of tube welding process was carried out with initial three preform-types (butt tube, overlap tube and welded tube). In the FEM simulation results, tube welding process using initial welded tube was evaluated to cause cracking of the specimen during the process. In actual making process of titanium alloys flux-metal cored wire for gas tungsten arc welding, overlap-type tube was evaluated to be the most suitable initial preform shape. In addition, it was confirmed that the filling ratio of the flux-metal was maintained uniformly at over 70%.

Purpose: This study assessed the growth and nutritional status of children in North Korean (NK) refugee families Methods: This study examined 301 children in NK refugee families. Their growth and nutritional status were estimated using the 2017 Korean National Growth Chart for Children and Adolescents. Stunting, being underweight, and wasting were defined as height-for-age (HAZ), weight-for-age (WAZ), and weight-for-height (WHZ) z -scores < -2.0, respectively. Results: The overall prevalences of stunting, being underweight, and wasting were 7.6%, 5.6%, and 5.0%, respectively. In children living in South Korea for < 5 years, the prevalences of stunting, being underweight, and wasting were 10.3%, 8.6%, and 3.4%, respectively, compared to 7.9%, 7.9%, and 0.0% for those living in South Korea for ≥5 years. The prevalences of WAZ and WHZ > 2.0 were 5.0% and 11.0%, respectively. Conclusion: Children in NK refugee families still suffer serious malnutrition after settling in South Korea, although being overweight is emerging as a new problem.
