박광원(Park Kwang-won),강현욱(Kang Hyun-wook) 한국여가문화학회 2018 여가학연구 Vol.16 No.4

이 연구의 목적은 질적연구방법을 활용하여 여가스포츠 활동에 참여하는 국내 외국인 이주근로자의 문화차이에 관한 현상에 대해 분석하고자 하였다. 특히 국내에서 경험한 외국인 이주근로자의 문화적이고 독특한 현상에 대해 구체적으로 탐색해보고자 하였다. 그 결과 총 세 가지의 의미 있는 결과로 분류할 수 있었다. 첫째, 여가스포츠 활동에 참여하고 있는 외국인 이주근로자들은 스포츠 현장에서 낯선 단체생활 위주인 새로운 한국문화를 수용하고 있는 태도를 보이는 것으로 나타났다. 둘째, 국내 외국인 이주근로자들은 스포츠 활동 참여에 참여하면서‘시간적 제약’과 ‘금전적 제약’을 겪고 있는 것으로 드러났다. 셋째, 국내 외국인 이주근로자들은 스포츠 활동에 참여하면서 국내 스포츠문화에 대한 이질감을 느끼고 있는 것으로 나타났다. 이러한 요인은‘스포츠현장에서의 과시성’과‘스포츠 장비에 관한 과도한 관심’ 등으로 분류할 수 있었다. The study’s aim is to analyzes the cultural differences of foreign migrant workers in South Korea who participated in leisure sports activities on the basis of qualitative method. Moreover, the study proved cultural and unique phenomenon from foreign migrant workers who experienced in leisure sports activities in South Korea. As a result, meaningful conclusions have become in this a research. Firstly, they had embraced a new Korean culture that values group activity such as getting a drinking time with group members after work or sports. Second, they had experienced ‘time and financial constraints’ while participating leisure sports activity. Third, they felt a sense of cultural alienation in the sports field from their culture such as ‘the flamboyance of Koreans on the sports field’ and ‘their excessive interest of sports equipment .

모나자이트광 속에 포함되어 있는 회토류 원소들을 이온교환수지를 이용하여 분리 회수 하는 방법에 관해 연구하였다. 이온교환수지로는 양이온교환수지와 음이온교환수지를 사용하고, 용리액으로는 EDTA, DTPA, IMDA, Ln-EDTA 용액을 사용하였으며, 양이온교환수지는 retaining 이온 곧 $H^+, Zn^{2+}, Fe^{3+}, Al^{3+}, Cu^{2+}, NH^+_4$으로 치환된 수지를 사용하였다. 음이온교환수지는 EDTA로 치환된 수지에 Ln-EDTA착물을 흡착시켜 분리하였다. 여러 가지 회토류 원소 중에서 선택적으로 한 원소만 분리하기 위해 용리액으로 Ln-EDTA를 사용하였으며, 수지통의 크기 변화와 여러 가지 용리형태의 메카니즘, 그리고 다량의 회토류 원소를 분리 회수하는 방법 등에 관해 연구하였다. The methods of separation and recovery of rare earth elements in monazite sand have been studied by the ion exchange chromatography. Both of cation and anion exchange resin were used as ion exchange resins and the solutions of EDTA, DTPA, IMDA and Ln-EDTA were used as eluents. The H+, Zn2+, Fe3+, Al3+, Cu2+, and NH4+ forms of cation exchange resin were used as retaining ions. Ln-EDTA solution was loaded on the EDTA form of anion exchange resin and separated. The Ln-EDTA solution was also used as an eluent for a selective separation of one element from the rare earth mixture solution. The size effects of resin column, the elution mechanism for the various elution types and the separation of a large amount of rare earths were studied.

김소현,박광원,백준석,정태영,김미리,박상준,Kim, So-Hyun,Park, Kwang-Won,Baek, Joon-Seok,Jung, Tae-Young,Kim, Mee-Lee,Park, Sang-Jun 대한악안면성형재건외과학회 2013 Maxillofacial Plastic Reconstructive Surgery Vol.35 No.1

Purpose: Many surgical procedures in oral and maxillofacial area can induce trauma to the peripheral nerve. The aim of the study is to evaluate the effects of short-term steroid therapy on nerve recovery after crush injury. Methods: Sixteen rats were randomly divided into two groups. The right sciatic nerves were exposed, crushed, and sutured. The control group was not given steroids. The test group was injected with dexamethasone disodium phosphate (2 mg/kg body weight/day) for 7 days. In all animals, compound muscle action potential (CMAP) was recorded before and at 1, 7, 14, 21, and 28 days after injury. Results: The amplitude of the CMAP before and at 1, 7, 14, 21, and 28 days after injury were $53.20{\pm}4.80$ mV, $20.12{\pm}5.38$ mV, $30.01{\pm}14.15$ mV, $31.14{\pm}13.56$ mV, $31.73{\pm}16.33$ mV, and $37.23{\pm}16.98$ mV in the control group, and $55.25{\pm}6.72$ mV, $18.62{\pm}6.26$ mV, $29.50{\pm}13.06$ mV, $32.90{\pm}13.226$ mV, $30.17{\pm}11.80$ mV, and $38.41{\pm}12.27$ mV in the test group, respectively. The nerve conduction velocity was $18.82{\pm}3.94$ m/s, $16.73{\pm}3.48$ m/s, $19.60{\pm}2.45$ m/s, $18.68{\pm}3.94$ m/s, $18.02{\pm}3.51$ m/s, and $19.25{\pm}3.88$ m/s in the control group, and $18.94{\pm}3.48$ m/s, $17.28{\pm}2.53$ m/s, $7.57{\pm}2.54$ m/s, $18.77{\pm}2.12$ m/s, $19.48{\pm}1.55$ m/s, and $19.22{\pm}2.97$ m/s in the test group, respectively. There was no significant difference between both groups (P>0.05). Conclusion: This study did not show any therapeutic effect of short-term administration of steroids on injured rat sciatic nerve. Further studies are needed.

차기원,박광원,Cha, Ki-Won,Park, Kwang-Won 한국분석과학회 1997 분석과학 Vol.10 No.6

Triton X-100 계면할성제 존재하에서, $Eu^{3+}$-thenoyltrifluoroacetone(TTA)계의 형광세기의 n-octanol 영향에 관해 연구하였고, n-octanol의 정량을 위한 최적 조건을 규명하였다. 이 착물계에서 들뜨기 파장을 345nm로 주사했을 때, $Eu^{3+}$ 이온의 최대 형광파장은 619nm에서 나타났다. n-octanol의 검정곡선은 $1{\times}10^{-5}M{\sim}1{\times}10^{-7}M$의 범위에서 직선적인 관계를 얻었고, 검출한계는 $1{\times}10^{-9}M$이었다. 이 방법을 이용하여 합성시료를 분석한 결과 분석오차내에서 기지값과 일치하였으며, 상대표준편차는 약 3.5%였다. The enhancing effect of n-octanol on the fluorescence intensity of the $Eu^{3+}$-thenoyltrifluoroacetone(TTA) system in the presence of Triton X-100 was studied using spectrofluorometric method. This complex exhibited very intense $Eu^{3+}$ ion fluorescence at 619nm, when optically excited at 345nm. Optimum conditions for the determination of n-octanol have also been investigated. The calibration graph was linear over the range $1{\times}10^{-5}M{\sim}1{\times}10^{-7}M$ and the detection limit for n-octanol is $1{\times}10^{-9}M$. The result obtained in the analysis of the synthetic sample agreed with the known value in the error range and the relative standard deviation was ca. 3.5%.
