연구 목적은 우수 양궁선수들의 심상 특성을 규명하는 것이다. 이를 위해서 연구 1에서는 고교선수 57명, 대학선수 25명, 일반 실업 선수 14명 등 총 96명을 대상으로 심상과 관련된 내용을 수집하고 귀납적 내용분석을 실시하였다. 연구 2에서는 연구 1의 결과를 토대로 8명의 우수 양궁 선수들을 심층 면접하여 심상 특성을 분석하였다. 연구 1의 결과, 고교 394 사례, 대학 117 사례, 실업 73 사례의 원자료 중 중복되거나 유사한 상황을 제외한 93개의 원자료를 채택하고, 이를 심상 시점과 장소, 심상 방법, 심상 내용영역으로 범주화하였다. 연구 2의 결과, 우수 양궁선수들은 주로 연습상황에서 심상을 많이 하는 것으로 나타났으며, 공식적인 심상훈련을 받은 적은 없지만 선수생활을 통해 쌓아온 자신의 경험을 활용하는 것으로 나타났다. 또한 외적으로 보이는 겉자세 보다는 속자세를 강조하고, 호흡, 시각, 운동감각을 활용하여 심상을 한다고 진술하였다. 대부분의 선수들이 장점만을 생각하는 긍정적인 심상을 했으며 양궁선수가 가져야 할 가장 중요한 심리적 요인으로 자신감을 꼽았다. 심상의 선명도는 그다지 뛰어나지 않았으며 심상의 선명도 자체에는 큰 관심이 없었다. 이들은 평소 연습 시에 많은 반복 연습을 통해서 자신의 속자세에 대한 명확한 단서를 확립했으며, 시합 시에는 그 느낌을 그대로 유지하여 자동화된 몰입으로 수행을 했기 때문에 심상이나 중재전략 없이 시합을 하는 것으로 나타났다. 마지막으로 개방형질문지의 결과와 우수양궁선수들의 결과를 논의하였으며, 양궁 심상에 대한 후속 연구를 제언하였다. The Purpose of this study was to investigate the Imagery trait of the Elite Archers. first, Open-ended questionnaire was asked 57 high school, 25 university and 14 professional archery athletes. Imagery-related data for open-ended questionnaire were collected and then their contents were analyzed inductively. According to the suggestion of validity committee, only 93 cases were adopted among 394 high school, 117 university and 73 professional cases except similar or repeated ones. Based on the results of validity committee, raw data were categorized into when, where, what, how. second, 8 elite archer participate the in-depth interview. The results of the interview showed that elite archery athletes have rarely participated in formal mental training programs but they used their knowledge gained by experience, and that they put more focus on their feeling during their usual practice and internal posture than on external posture. Therefore internal Imagery can be said to be utilized. Relaxation is often regarded as a prerequisite for Imagery but the result of this study showed that athletes used progressive relaxation techniques a little, not so much. But they always imagined positive image and considered confidence image is the most important quality they must have. They didn`t have great vividness of Imagery. Some did but others not. They didn`t pay much attention to the vividness itself. Athletes established their own sense of the internal posture through their usual practice and repetition and keep the feeling in a competition and perform automatically without any Imagery or intervention. We are discussed about the different results between non elite archers and elite archers. Finally we proposed imagery research for archery field.

본 연구의 목적은 스포츠 동아리 활동에 참가하는 청소년들의 신체적 자기개념과 정서의 차이와 관계를 밝히는 것이다. 경기도 소재 고등학교 1,2학년 학생들 312명(남:206, 여106)을 대상으로 신체적 자기개념 질문지(PSDQ)와 한국어판 기분상태프로파일(K-POMS)을 이용해 자료를 수집하였다. 수집된 자료는 SPSS 12.0을 이용하여 t-test one-way ANOVA. 단계적 중다회귀분석을 하였고, 유의수준은 P<.05로 하였다. 분석결과 첫째, 남학생이 여학생보다 신체적 자기개념의 하위요인과 정서의 활력요인에서 높게 나타났다. 둘째, 스포츠동아리 활동 집단이 비활동 집단보다 신체적 자기개념의 하위요인(외모, 건강, 규칙운동, 체지방, 스포츠자신감, 지구력)과 정서의 활력요인에서 높은 점수를 나타냈다. 셋째, 중다회귀분석 결과 스포츠동아리 활동 청소년은 신체적 자기개념의 근력과 외모요인이 정서를 주로 설명하는 예측변인으로, 비활동 청소년은 건강과 외모요인이 정서를 주로 설명하는 예측변인으로 나타났다. The purpose of this study was to examine the difference and relationship of physical self-concept and emotions in sport club youths. The subjects of this study was 312(men;206, women;106) of high school students in Kyonggi province. The Questionnaire employed at this study was Physical Self-Description Questionnaire(PSDQ) and Korean edition of the POMS(K-POMS). This study analyzed t-test, one-way ANOVA, stepwise multiple regression analysis by SPSS 12.0K versions. All these statistic values were tested in the significant level of p<.05. The conclusions were as follows. First, male students had got a better score than female students and the group who participated in some sports activities also had got a better score than the others in the sub-factors of physical self-concept and vigor factor of emotions. Second, activity group of sport clubs had got better score than non-activity group in a sub-factors(physical attractiveness, health, physical activity, body fat, sport competence, endurance) of physical self-concept and vigour factor of emotion. Third, strength and physical attractiveness factors of physical self-concept in sport clubs youth turned out to be antecedent variables that explain emotion, but health and physical attractiveness factors of physical self-concept in non-activity youth turned out.

Background: The verbal fluency test consists of two separate tests of semantic fluency and phonemic fluency. The performance patterns of these tests differ with the type of dementia. We studied the patterns of verbal fluency between Alzheimer’s disease (AD) and subcortical vascular dementia (SVaD), and assessed the clinical utility of these tests. Methods: The 1,475 selected participants comprised 73 normal control subjects, 673 patients with amnestic mild cognitive impairment (aMCI), 535 AD patients, 42 patients with subcortical vascular mild cognitive impairment (svMCI), and 152 SVaD patients. We analyzed the z-score for the total number of animal items as a semantic fluency index and the z-score of the phonemic total score as a phonemic fluency index. Results: The performance of semantic fluency was lower than that of phonemic fluency in all groups. The SVaD group showed the worst scores and abnormal performances on both tests, while the AD group presented abnormal performance only for semantic fluency. Dividing the patients with dementia according to severity revealed a different pattern between AD and SVaD for the clinical dementia rating (CDR) stage of 0.5. The performance of the AD group declined gradually with CDR. However, the SVaD group performed very poorly in both tests even for very mild dementia (CDR stage of 0.5). The aMCI and svMCI groups exhibited similar performance patterns. Conclusions: The pattern of semantic and phonemic fluency was not clinically useful at the MCI stage, but it could be helpful in differentiating AD and SVaD in the early stage of dementia.

기관재건술 후 발생한 심부 종격염 -흉골 절제, 위망 이식, 근피성형을 병합한 근치술-

이서원,김정택,김광호,이충재,김영모,임현경,선경,Lee, Seo-Won,Kim, Jung-Taek,Kim, Kwang-Ho,Lee, Choong-Jae,Kim, Young-Mo,Lim, Hyun-Kyoung,Sun, Kyung 대한흉부심장혈관외과학회 1999 Journal of Chest Surgery (J Chest Surg) Vol.32 No.2

기관재건술 후 발생한 심부 종격염 2례에 대해 흉골절제, 대위망 자유이식 혹은 전치술, 근피성형술을 병행하여 좋은 결과를 얻었기에 보고한다. 증례 I은 8세된 남아에서 흉골 정중절개로 전방기관성형술을 실시한 후 심부 종격염과 흉골 골수염이 발생한 경우였으며, 증례 II는 50세된 여자에서 상부 흉골의 부분 정중절개로 기관절제 및 단단문합을 실시한 후 종격농양과 흉골 골수염이 발생한 경우였다. 치료는 두례 모두 배농을 시키고 일정기간 세척한 다음, 골수염이 생긴 흉골을 광범위 절제하고 대위망으로 종격을 덮은 후 양측 대흉근을 피부와 함께 박리하여 전흉벽을 재건하였다. 이때 증례 I의 경우는 대위망을 분리한 뒤 횡격막을 통해 종격부위에 위치시켰으며 (in-situ pedicled grafting), 증례 II의 경우는 대위망을 자유이식편으로 만들어 우횡경동맥과 외경정맥에 연결한 후 피하출구을 통해 상부종격에 위치시켰다 (free grafting). 양례 모두 술후 쾌회복하였으며 외래를 통해 추적관찰 중이다. We report here 2 cases of deep-seated mediastinitis combined with sternal osteomyelitis after tracheal reconstruction which were successfully treated with sternectomy, in-situ or free omental transfer, and pectoralis major myocutaneous flap. In case I, an 8 year-old boy with deep seated mediastinitis and sternal osteomyelitis that developed after anterior tracheoplasty through a standard midline sternotomy. In case II, a 50 year-old female patient with mediastinal abcess and sternal osteomyelitis that developed after resection and end-to-end anastomosis of the trachea through an upper midline sternotomy. Treatments consisted of drainage and irrigation followed by wide resection of the infected sternum, placement of the viable omentum into the anterior mediastinal space, and chest wall reconstruction with a pectoralis major myocutaneous flap. The omentum was transferred as an in-situ pedicled graft in case I and a free graft in case II. Both patients have recovered smoothly wit out any events and have been doing well postoperatively.

공공기관 종사자의 공공성 인식유형 연구:Q 방법론을 활용하여

이서호,김다솜,홍성우,배수호 서울대학교 한국행정연구소 2024 行政論叢 Vol.62 No.1

This paper goes further than the previously discussed publicness discourse and seeks to examine the types and characteristics of publicness based on an individual’s subjective perception. Specifically, we aim to derive public interest implications for our society by targeting employees in public enterprises who can expect more public value than any other occupational groups, and typifying their perceived publicness. For this purpose, we used the Q methodology, which can quantitatively understand an individual’s subjectivity. The specific analysis results are as follows. First of all, the perception of publicness is largely divided into the three types. Type I was named ‘Publicness based on procedural fairness’, Type II was named ‘Publicness based on deliberation’, and Type III was named ‘Publicness based on utilitarianism’. Respectively, each type of publicness emphasizes the process aspect, the reflection and deliberation aspect, and the public interest aspect in recognizing publicness. This typification exhibits different content properties from the discourse of publicness according to conceptual implications, thus allowing a clearer understanding of the social orientation value of publicness that reflects an individual’s subjectivity and providing useful social implications in the field of public policy.

Purpose: The objective of this study was to evaluate the effect of microthreads on removal torque and bone-to-implant contact (BIC). Methods: Twelve miniature pigs for each experiment, a total of 24 animals, were used. In the removal torque analysis, each animal received 2 types of implants in each tibia, which were treated with sandblasting and acid etching but with or without microthreads at the marginal portion. The animals were sacrificed after 4, 8, or 12 weeks of healing. Each subgroup consisted of 4 animals, and the tibias were extracted and removal torque was measured. In the BIC analysis, each animal received 3types of implants. Two types of implants were used for the removal torque test and another type of implant served as the control. The BIC experiment was conducted in the mandible of the animals. The P1–M1 teeth were extracted, and after a 4-month healing period, 3 each of the 2 types of implants were placed, with one type on each side of the mandible, for a total of 6 implants per animal. The animals were sacrificed after a 2-, 4-, or 8-week healing period. Each subgroup consisted of 4 animals. The mandibles were extracted, specimens were processed, and BIC was analyzed. Results: No significant difference in removal torque value or BIC was found between implants with and without microthreads. The removal torque value increased between 4 and 8 weeks of healing for both types of implants, but there was no significant difference between 8 and 12 weeks. The percentage of BIC increased between 2 and 4 weeks for all types of implants,but there was no significant difference between 4 and 8 weeks. Conclusions: The existence of microthreads was not a significant factor in mechanical and histological stability.
