이 연구의 목적은 동물실험과 임상실험을 통해 변비 치료에 Lactobacillus acidophilus와 Pediococcus pentosaceus, Bifidobacterium longum SPM1205를 포함한 유산균(Lactic Acid Bacteria, LAB) 및 비피더스균 혼합제제의 효과를 평가하기 위한 것이다. 5마리의 ICR 마우스와 4명의 여성 변비 환자들은 2주 동안 유산균 및 비피더스균 혼합제제를 복용하였다. 복용 전과 후에 분변에서 유산균수와 유해 효소 활성을 측정하였으며 그 결과 분변 중 유산균수가 증가하였고, 장내 미생물에 의한 유해 효소 활성은 일반적으로 감소하였다. 또한, 61명의 피실험자들은 유산균 및 비피더스균 혼합제제와 lactose 중의 하나를 2주 동안 하루에 3번 복용한 후, 설문지를 작성하였다. 이를 분석한 결과, 변비환자군에서 매일 유산균 및 비피더스균 혼합제제를 복용한 군(56.3%)은 lactose를 복용한 군(26.7%)보다 변비증상이 개선되었고, 단단한 변의 배변 횟수가 0.22에서 0.03으로 감소하였다. 따라서 L. acidophilus와 P. pentosaceus, B. longum SPM1205를 포함한 유산균 및 비피더스균 혼합제제는 변비를 개선할 수 있을 것으로 예상한다. The aim of this study was to evaluated the efficacy of mixture of Lactic Acid Bacteria (LAB) and bifidobacteria supplement, which are contained with Lactobacillus acidophilus, Bifidobacterium longum SPM1205, and Pediococcus pentosaceus for the management of constipation in animal model and clinical trials. 5 ICR mice and 4 female constipation subjects were orally taken mixture of LAB and bifidobacteria for 2 weeks. We investigated the number of fecal LAB and harmful enzymes activities before and after mixture of LAB and bifidobacteria application. As a result, fecal LAB count was increased and harmful enzymes activities of intestinal microflora were generally decreased after mixture of LAB and bifidobacteria application. Also, 61 female subjects were randomly assigned to receive either mixture of LAB and bifidobacteria or lactose and were taken three times a day for 2 weeks. Then, we analyzed mixture of LAB and bifidobacteria effect through the questionnaires. Daily consumption of this mixture of LAB and bifidobacteria improved the constipation in constipation group (56.3%) compared with lactose application group (26.7%). Furthermore, after mixture of LAB and bifidobacteria treatment, frequency of hard stool decreased from 0.22 to 0.03. These results indicated that mixture of LAB and bifidobacteria application is effective to improve the constipation.

Extensor hallucis brevis (EHB) is only extensor of the first metatarsophalangeal (MTP) joint after modified Jones procedure. Therefore preserving the normal insertion of the EHB has been emphasized during that procedure. We experienced a case of EHB rupture after modified Jones procedure and had satisfied surgical outcome by partial transfer of extensor digitorum longus (EDL) of second toe.

김정래,김성윤,이우천,Kim, Jung-Rae,Kim, Sung-Yoon,Lee, Woo-Chun 대한족부족관절학회 2012 대한족부족관절학회지 Vol.16 No.2
Purpose: The aim of this study was to investigate the radiological characteristics of the osteoarthritis of the second metatarsophalangeal (MTP) and tarsometatarsal (TMT) joint. Materials and Methods: Between January 2002 and August 2010, 27 patients (33 feet) who had second metatarsal osteoarthritis (OA) were reviewed retrospectively. Group 1 was 14 patients (17 feet) with second MTP joint OA. Group 2 was 13 patients (16 feet) with second TMT joint OA. Group 3 was 24 patients (25 feet) had hallux valgus without second metatarsal (MT) OA as control. Weight bearing foot anteroposterior (AP) and lateral view were checked, and measured hallux valgus angle, metatarsus adductus angle (MAA), second MT functional length, first and second MT length by Hardy & Clapham method on AP view, angle of second MT with horizontal plane, calcaneal pitch, talo-first MT on lateral view. Results: On weight bearing foot AP view, second MT functional length of group 1, 2, 3 was 2.4 mm, -0.1 mm, 0.7 mm and MAA of group 1, 2, 3 was $17.7^{\circ}$, $17.7^{\circ}$, $14.5^{\circ}$. Second MT functional length of group 1 was longer than control group and it was statistically significant. MAA was significant different between group 1-3 and group 2-3. Angle of second MT with horizontal plane of group 2 was smaller than control group and it was statistically significant. Other radiographic parameters have no statistical significance. Conclusion: Group 1 has long functional length of second MT and group 2 has small angle of second MT with horizontal plane.
족관절 관절염이 있는 환자에서 체중 부하상태의 양측 족관절과 환측 족관절 전후면 방사선 사진의 방사선학적 측정치의 비교
김정래,이우천,Kim, Jung-Rae,Lee, Woo-Chun 대한족부족관절학회 2011 대한족부족관절학회지 Vol.15 No.3
Purpose: This study was performed to analyze the results of radiologic parameters between weight bearing affected single ankle anteroposterior (AP) view and both ankle AP view in ankle osteoarthritis (OA). Materials and Methods: Between January 2009 and August 2010, 41 patients (50 ankles) who visited our institution to treat ankle OA were reviewed retrospectively. In radiographic assessment, weight bearing affected single ankle AP view and both ankle AP view were checked, and measured tibial anterior surface angle (TAS), tibial medial malleolar angle (TMM), talar tilting angle (TT), maximum and minimun joint space width (JSW) of ankle, width between articular surface of medial malleolar and medial articular surface of talus as radiologic parameters. Results: On weight bearing both ankle AP view, TAS was $85.4{\pm}4.1^{\circ}$, TMM was $33.1{\pm}9^{\circ}$, TT was $5.4{\pm}6.1^{\circ}$, maximum JSW was $3.2{\pm}2.7$ mm, minimum JSW was $1.1{\pm}1.3$ mm, width between articular surface of medial malleolar and medial articular surface of talus was $1.8{\pm}1.8$ mm and on weight bearing affected ankle AP view, TAS was $85.3{\pm}3.9^{\circ}$, TMM was $34.3{\pm}10.9^{\circ}$, TT was $5.4{\pm}6.5^{\circ}$, maximum JSW was $3.2{\pm}2.7$ mm, minimum JSW was $1.1{\pm}1.3$ mm, width between articular surface of medial malleolar and medial articular surface of talus was $1.6{\pm}1.7$ mm. Conclusion: There is no statistical significance in radiologic parameters between weight-bearing affected single ankle AP view and both ankle AP view in ankle OA.
Entrepreneurship in Entertainment Industry: Marketing Self-efficacy and Start-up Intention
Jung-Rae Kim(김정래) 한국엔터테인먼트산업학회 2020 한국엔터테인먼트산업학회논문지 Vol.14 No.8
그동안 창업의지 선행요인에 관한 연구에서 자기효능감과 창업효능감은 많은 관심을 받아 왔다. 그러나 마케팅과 기업가 정신이 기업 설립 과정에서 중요한 역할을 하고 있음에도 불구하고 자기효능감과 창업효능감과 밀접한 관련이 있고, 창업의 핵심역량인 마케팅 효능감에 관한 연구는 제한적이다. 더욱이 기존 선행연구가 존재하지만 이전 연구의 대부분은 경제학과 경영학을 전공한 대학생에 초점을 맞추고 있다. 그 결과 마케팅 효능감과 창업의지간의 관계에 대한 이해는 여전히 부족하다. 이에 본 연구는 국내 엔터테인먼트 관련 전공 대학생의 마케팅 효능감이 창업의지에 어떠한 영향을 미치는지 분석하고자 한다. 이를 위해 국내 3개 대학의 엔터테인먼트 관련 전공 대학생을 대상으로 총 120부를 최종 분석하였다. 연구 분석 결과, 마케팅 효능감은 창업의지에 유의한 영향을 미치는 것으로 나타났다. 즉, 엔터테인먼트 관련 전공 대학생의 마케팅 효능감 수준이 높을수록 창업의지가 높아진다는 것이다. 본 연구결과는 이론적·실무적 시사점을 제공한다. Self-efficacy and entrepreneurial self-efficacy on the positive effects of entrepreneurial intention are well developed in past research but marketing self-efficacy, linked to the competencies of marketing field and is closely related to self-efficacy and entrepreneurial self-efficacy has not received enough attention on the prediction of start-up intention despite marketing and entrepreneurship are crucial when creating a start-up. Moreover, there have been several empirical studies but, most of the previous studies have focused on university students majoring in business and economics. Therefore, there is still little understanding of the effect of marketing self-efficacy on start-up intention. The purpose of this study then was to investigate the effect of marketing self-efficacy on start-up intention for college students majoring in entertainment-related studies. Questionnaires were employed to collect data from three universities in Korea. A total of 120 completed questionnaires were returned. Logistic regression analysis was used to test the hypothesis. The results indicate that marketing self-efficacy was positively and significantly related to start-up intention. The results of this study empirically confirmed that university students majoring in entertainment-related studies with high marketing self-efficacy are more likely to desire to create a start-up. These results suggest theoretical and practical implications.
