박경진 ( Park¸ Kyoung-jin ),배주용 ( Bae¸ Ju-yong ),이상호 ( Lee¸ Sang-ho ) 한국융합과학회 2021 한국융합과학회지 Vol.10 No.5

연구목적: 농구선수에게 체격과 기초체력이 매우 중요하다. 이러한 필요성을 바탕으로 한국프로농구(KBL)에서는 학생 엘리트 농구 선수들을 지원하고, 우수 프로농구 선수로 양성하기 위하여, 2019년부터 매년 학생 농구선수들의 신체조성과 기초체력 등의 측정을 실시하고 있다. 이에 본 연구에서는 2019년도 대한민국농구협회에 등록된 학생선수들을 대상으로 KBL에서 측정한 초·중·고등학교 선수들의 체격과 기초체력을 제시하고, 지역별로 비교분석하는데 목적이 있다. 연구방법: 2019년도 대한민국농구협회에 등록된 전국 엘리트 남자 농구 초등 21팀(190명), 중등 27팀(313명), 고등 18팀(127명)을 대상으로 실시하였다. 초등학생 선수들은 4~6학년, 중학생 선수들은 1~3학년, 그리고 고등학생 선수들은 1~2학년이 측정에 참여하였다. 결과: 체격의 경우 신장, 체중, 다리길이, 양팔길이, 스탠딩리치에서 수도권과 광역시에 비해 지방선수들이 낮은 경향이 나타났다. 체력 또한 체격의 경우와 유사하게 수도권과 광역시에 비해 지방선수들이 낮은 경향이 나타났다. 결론: 선수들의 체격과 체력은 경기 승패를 좌우하는 중요한 요소이다. 체격과 체력을 측정한 결과 수도권과 광역시에 선수들의 기량이 편중되어 있어 지방 팀의 경기 수행력이 약하다. 수도권에 편향된 지원은 팀의 안전성과 성적에 기여하며, 우수한 지방 선수의 이탈을 발생시키는데 영향을 미침으로써, 지방 학교 체육의 쇠퇴를 가중시킬 수 있다. 따라서 지방자치단체 및 체육회, 그리고 지방 연고 프로팀에서의 학교 엘리트 선수 양성에 관심과 지원이 더욱 절실히 요구된다. Purpose: The purpose of this study is to measure the physique and physical strength of elementary, middle, and high school male elite basketball players who were registered with the Korea Basketball Association, and to compare and analyze the results by regional groups. Methods: This study was conducted from May to November, 2019, and was conducted on 21 elementary school teams(190 players), 27 middle school teams(313 players), and 18 high school teams(127 players). Results: Standing reach of elementary school students was higher in the metropolitan area students than in the provincial(p<.05), and standing reach of middle school students was higher in the metropolitan area and metropolitan students than in the provincial students (p<.05). Vertical jump and running jump in the elementary school students were lower in the provincial students than in the metropolitan area students(p<.05). 3/4 court sprint in the middle school students was slower in the metropolitan students than in the metropolitan area students(p<.05), and that by high school students was slower in the metropolitan students than in the provincial students(p<.05).

Conclusion: The results of this study can be used as reference data for selecting elite student basketball players, and it can be helpful in setting goals for improving the physical strength of student elite basketball players. In addition, externally, it is

Ways of prevention of thread extrusion after insertion of polydioxanone thread for nasal tip projection

Kyoungjin Kang(Kyoungjin Kang),Jaeran Hong(Jaeran Hong),Yibeom Shin(Yibeom Shin) 대한미용의학회 2023 대한미용의학회지 Vol.7 No.1

Cogged polydioxanone (PDO) thread, which is inserted into the blunt cannular, is cosmetically used for non-surgical projection of the nasal tip. However, thread extrusion is a frequently occurring side effect despite the production technology of the thread has improved. To prevent this, we changed the location of the insertion site from the middle of the tip to 0.5 cm above the supratip break point and applied the cannular, which was manually bent about 30°, 1.5 cm from the cannular tip. The bent cannular was located in the supraperichondral layer of the upper lateral cartilages, moved down to middle of the tip, rotated 180°, and the columella inserted inwards to the nasal spine by holding the nose in the desired position of tip projection with the non-dominant hand. For tip projection, 4 threads were inserted. For dorsal augmentation, 1.0 ml hyaluronic acid (HA) filler was injected as a single approach, and both 8 threads and 1.3 ml HA filler were used as a combination approach. The effect was maintained for at least 2 years after the procedure, without any thread extrusion. The patient was greatly satisfied with the natural appearance. This method is an easy and reliable technique for both tip projection and preventing thread extrusion.

Kyoungjin Kang,FKCCS,Choongyee Chai 대한미용의학회 2018 대한미용의학회지 Vol.2 No.1

Background: For correction of small chin, surgical genioplasty, allograft implantation, and injectable filler have been widely used. Among these, the injectable fillers is a simple, non-invasive procedure that has minimal downtime and low risk of complications. It has been commonly injected at intradermal, subdermal, submuscular and supraperiosteal layer. However, common complications such as nodules, bumps, lumps, migration, asymmetry, overcorrection, and chin ptosis frequently happened. Objective: The main objective of this study was injecting filler into sub-periosteal layer in a small chin and evaluated its effect and incidence of complications. Methods: A total of 14 subjects aged between 33 and 64 years had been performed Elravie ?? hyaluronic acid filler injection subperiosteally and Medytoxin ?? as a botulinum toxin treatment intramuscularly. Morphological change were observed through the photos. Changes of proportion of lower 1/3 face, Modified Legan’s angle, and open gap distance of lips were measured. Follow-up patient satisfaction surveys were conducted from 2 to 3 weeks. Results: Proportion of lower face was significantly changed that the ratio of upper and middle 1/3 were decreased (5.26%, 3.85%) and the ratio of lower 1/3 was increased (8.33%). Modified Legan’s angle was significantly decreased (37.4±16.5%). Open gap distance between lips was decreased (66.2±17.9%) and dry mouth was significantly decreased. Lower facial contour was changed from round shape to elliptical shape and mouth looked smaller and less protruded. Upper lip was everted, but lower lip was inverted. Perioral wrinkles, labio-mandibular folds, and mental dimples were significantly decreased. There was no significant incidence of common complications including chin ptosis. Conclusion: Subperiosteal filler injection is easy, safe and effective in improvement of small chin and interestingly, showed additional beneficial effects such as improvement of dry mouth, lips contour, and perioral wrinkles. Level of Evidence: IV

Kyoungjin Kang,Moon Hee Kim,Hyeon Seob Byeon 대한미용의학회 2020 대한미용의학회지 Vol.4 No.1

Drooping of the nasal tip is one of the main complications of rhinoplasty. Herein we describe the case of a 42-year-old female who underwent simple augmentation rhinoplasty using an I-shaped silicone implant approximately 3 years ago visited our clinic for the correction of a drooping nose. The contour of the I-shaped silicone was observed in the dorsum of the nasal skin above the supra-tip break point, which caused the nasal tip to droop. The patient refused revision rhinoplasty and requested to temporarily correct the drooping nose using a noninvasive procedure. Sequential augmentation of filler injection (SAFI) for rotation, projection, and augmentation was recommended to correct the condition. In total, 0.6 ml of hyaluronic acid (HA) filler was first injected into the dead space between the anterior nasal spine and end of the medial crus of the lower lateral cartilage and columella for tip rotation. It was then placed intranasally on top of the middle crus of the lower lateral cartilage for tip projection (0.2 ml). Finally, it was injected into the upper lateral cartilage around the supra-tip break for dorsal augmentation (0.4 ml). A total of 1.2 ml of filler was injected. After 2 weeks, 0.2 ml of HA filler was injected for tip rotation. After 4 months, a postoperative follow-up study was performed. The nasolabial angle had changed from 90° to 105°. Tip projection was significantly increased. The abnormal contour of the silicone implant in the dorsum was no longer visible. The drooping nose remarkably improved with the sequential combination of rotation, projection, and augmentation using the SAFI technique, which considers the dynamic structure of the nasal tip. We were able to demonstrate that the SAFI technique can be a reliable technique for filler rhinoplasty.

Kyoungjin Seong,Dooman Kim,Hyunseung Yoo,Injieong Park,Sungchan Kim 한국자동차공학회 2004 한국자동차공학회 지부 학술대회 논문집 Vol.- No.-

Tire carcass is a basic structural part for maintaining stiffness of tire. As deformation property confirmation of tire carcass in transmitting or driving is essential subject with respect to tire design. Tires have geometrical shape of doughnut and consist of steel cord-rubber, which have much difference in properties, so these structures are difficult to analyze mechanically. For that reason, ABAQUS program for analyzing structural characteristics of automobile tire widely used in the fields of mechanical and automobile industries. In this study, the non-linear analysis method and numerical results of method radial tire are briefly introduced. And carcass deformation behavior of radial tire is conducted by using the ABAQUS. A calculated numerical result is compared result of experimental.

Vulvar extramammary Paget disease in a completely prolapsed uterus: A case report

( Kyoungjin Chang ),( Joo-hyuk Son ),( Tae-wook Kong ),( Jiheum Paek ),( Suk-joon Chang ),( Hee-sug Ryu ) 대한산부인과학회 2016 대한산부인과학회 학술대회 Vol.102 No.-

Background: Extramammary Paget disease (EMPD) is an unusual skin neoplasm with unclear pathogenesis. The most common site of involvement is the vulva. Vulvar EMPD associated with third degree uterovaginal prolapse is very rare. Case: We report a case of a third-degree uterine prolapse complicated by an isolated vulvar EMPD and its surgical treatment. A 79-year-old woman was referred from a secondary care hospital with third degree uterovaginal prolapse and persistent vulvar itching and pain. Gynecologic examination showed a pigmented vulvar erythematous plaque, and a subcutaneous nodule in the major labia. A biopsy of the lesion revealed a vulvar EMPD. Neither internal malignancy including colorectal or genitourinary carcinoma nor distant metastasis was identified in any of the clinical examinations. She received laparoscopically assisted vaginal hysterectomy with bilateral salpingo-oophorectomy, radical vulvectomy with primary closure, and lateral suspension of vaginal vault with mesh. A histopathologic examination of the resected vulvar specimen revealed Pagetoid tumor cells that had spread through the epidermial layers without dermal invasion. She was diagnosed as FIGO stage IB vulvar cancer and did not receive any adjuvant therapy. No complications occurred during the wound healing process. Conclusion: Vulvar itching and pain associated with long standing genital prolapse need careful evaluation including punch biopsy for underlying carcinoma. We suggest surgical excision and laparoscopic suspension of vaginal vault with mesh as the optimum treatment for early stage vulvar EMPD associated with genital prolapse.

Intraoperative visible iris sign detected during ptosis surgery in seven Korean patients who wore eye masks when sleep

Kyoungjin Kang 대한미용의학회 2019 대한미용의학회지 Vol.3 No.2

Background: A visible iris sign (VIS) is the apparent visibility of iris color or contour through a closed upper eyelid in patients with aponeurotic ptosis from Western countries. This has been popularly reported in individuals from Western countries because the soft tissue of their lids is much thinner than that in individuals of Oriental descent. There is no report on VIS in individuals of Oriental descent pre- and intraoperatively. Objective: This study aimed to evaluate patients who wore eye masks when sleeping at night and assess the association between VIS and habitual wearing of sleeping mask while dissecting the eye lids to correct ptosis. Methods: Among the patients who visited the clinic for cosmetic blepharoplasty from 2018 to 2019, seven patients complained about the inconvenience of wearing eye masks for sleeping at night. Of these, two patients were diagnosed with pseudoptosis, and the others were diagnosed with aponeurotic ptosis preoperatively. Moreover, they presented with allergy, contact lens use, habitual eye rubbing, and dry eye syndrome. VIS was assessed pre- and intraoperatively, and pre- and intraoperative images were obtained. VIS was analyzed intraoperatively. Conventional blepharoplasty with ptosis correction was performed, and morphological characteristics of the lid layers were observed. Results: Preoperative VIS was not observed in all patients. However, positive intraoperative VIS was detected in six patients, which appeared as a black-colored region due to the defect from the orbital septum, aponeurosis, and Müller muscle. Five patients were diagnosed with aponeurotic ptosis. Moreover, two patients were finally diagnosed with subclinical aponeurotic ptosis because the anatomical defects were observed in these two patients who were preoperatively diagnosed with pseudoptosis. Conclusion: A sleeping eye mask was most likely used to decrease light transmission through the anatomical defects in patients with positive intraoperative VIS.
