김동제,조성구,한삼석 국회입법조사처 2015 입법과 정책 Vol.7 No.1

In Korea, private investigation is regulated by 「USE AND PROTECTION OF CREDIT INFORMATION ACT」 but private investigation companies are growing illegally as a messenger office because of limitation of police power and expanding demand of public order by the public. On the other hand, private investigation businesses have been entered into general use as an important area of private security in advanced countries and also the private investigation businesses are introduced to protection of the public's life and property in every OECD-member countries except Korea. Meanwhile, multinational private investigation companies are in the market after Korea joined OCED group in 1996 and a legislation for the private investigation has been attempted to legislate nine times by a member of the National Assembly, Ha, Soon-Bong in 1999 but it have been foundered as interest groups' resistance. By the way, in past cabinet meeting, on march 18, 2014, a private investigator was included to promotion plan for new occupation so a legislation of the private investigation is getting power. The present, legislations are pending a member of the National Assembly, Yoon, Jae-Ok's 「All Amendments Private Security Act」 and a member of the National Assembly, Song, Young-Geun's 「Private Investigation Act」 in the assembly. The present, the predominant view regard private investigation business as a kind of private security so this study attempt to result of legalization questingly. As results of this study, an introduction of private investigation system through amending 「Security Services Industry Act」 shows positively in convenience to management but in character and operation of organization in the private investigation business and an expertise aspect show negatively. 우리나라에서의 민간조사업은 「신용정보의이용및보호에관한법률」에 의해 규제를 받고 있으나 국민의 치안수요의 확대와 경찰력의 한계는 심부름센터와 같은 불법적인 업체의 증가로 이어져 오고 있다. 그러나 외국의 선진국에서는 민간조사업을 민간경비의 주요영역으로서 일반화되어 있으며, 현재 OECD회원국 중 우리나라를 제외한 모든 국가에 정착되어 국민의 생명과 재산보호에 앞장서고 있다. 한편 우리나라에서도 OECD회원국으로 가입한 1996년부터 외국의 다국적 민간조사업체가 국내 시장에 들어와 있으며 1999년 한나라당 하순봉의원 이후 9차례의 입법화 시도가 이루어졌으나 주무관청을 둘러싼 이익단체의 반발로 무산되어 왔다. 그런데 지난 2014년 3월 18일 국무회의에서 민간조사원이 신직업 육성 추진계획에 포함되어 입법화에 힘을 얻고 있고, 현재의 19대 국회에서는 윤재옥의원의 「경비업법전부개정안」과 송영근의원의 「민간조사업에 관한 법률안」이 계류 중에 있다. 현재의 입법화를 근거로 볼 때 19대 국회 윤재옥 의원(안)과 같이 민간조사업을 경비업의 하나로 보는 시각이 지배적이다. 따라서 이 연구에서는 이러한 입법화 결과에 대하여 탐색적으로 살펴보고자 하였으며 연구결과 「경비업법」 개정을 통한 민간조사제도의 도입은 기존의 경비업체에서 민간조사업무만 추가하면 되기 때문에 경영적 편리성은 긍정적이었으나 민간조사업무의 특성과 조직운용 그리고 전문성 측면에서는 부정적인 인식을 가지고 있었다.

Ornitine α - Ketoglutarate 와 Creatine 복합투여가 무산소성 파워와 혈중 젖산 및 암모니아 농도에 미치는 효과

김동제,안의수 한국운동과학회 2001 운동과학 Vol.10 No.1

Ornitine α-Ketoglutarate와 Creating 복합 투여가 무산소성 파워와 혈중 젖산 및 암모니아 농도에 미치는 효과. 운동과학, 제10권 제1호, 1-11, 2001. 본 연구의 목적은 크레아틴 섭취로 인한 30초간의 무산소성 파워 테스트시 생성되는 젖산과 암모니아의 생성을 억제시키기 위하여 체육을 전공하고 선수 경력이 없는 남자 대학생을 대상으로 Ornitine α-ketoglutarate와 Creatine의 복합 제제 섭취시 무산소성 파워와 혈중 젖산 및 암모니아 농도에 미치는 효과를 관찰해 본 연구 결과 다음과 같은 결론은 얻었다. 1. 무산소성 파워에서 OKG와 Creating의 복합 제제 섭취가 위약군과 크레아틴 섭취군보다 유의한 증가를 보였다(p<.05). 2. 운동 수행 시 혈중 젖산 농도는 처치군에서 유의한 차이는 나타나지 않았지만 채혈시점별에서 운동직전(p<.01) 및 운동직후(p<.01)에서 유의한 차이를 보였다. 3. 운동 수행 시 혈중 암모니아 농도는 OKG와 Creative의 복합 제제 섭취군이 위약군과 크레아틴 섭취군보다 유의한 감소를 보였다(p<.05). 이상의 결과를 종합하여 볼 때 OKG와 Creatine의 복합 제제 섭취가 고강도의 짧은 운동 수행시 효소 활성도와 그와 관련된 아미노산에 영향을 미쳐 무산소성 파워의 증가와 젖산과 암모니아 생성량을 억제시켜 피로를 줄이고 나아가 운동수행 능력 향상에 효과적인 것으로 사료된다. The effect of blood lactate, ammonia density and anaerobics power by ornitine α-ketoglutarate and creatine mixed administration. Exercise Science, 10(1): 1-11, 2001. The purpose of this study was to verify the effect that the administrated combination product of Ornitine α-ketoglutarate ("OKG") and Creatine may have on the anaerobic power and the lactic acid and, ammonia level. In order to restrain the production d lactic acid and ammonia, due to simultanous administration of such combination product, during the anaerobic power test for 30 seconds, observation was made of a male college student who majored in physical education but has no experience of athletes. Out of this study, a condusion on was reached as summarized hereinafter. 1. The group having administrated a combination product of OKG and Creatine showed more significant increase in anaerobic Power than placebo group and the group having ingested Creatine only. (p<.05). 2. While taking exercise, any groups showed no significant difference in the density of blood-lactic acid but at the time of collecting blood, there were significant differences in rest2 (p<.01) and post(p<.01). 3. While taking exercise, the group having administrated a combination product of OKG and Creatine showed more significant decease in blood-ammonia level than placebo group and the group having ingested Creatine only (p<0.5). Reviewing the above-mentioned results all together, it follows that the ingested combination product of OKG and Creatine affects the activation of enzymes and related amino acids during taking exercise of high intensity for a short time, thus enhancing anaerobic power and restricting the production of lactic acid and ammonia, which is of effect to decreasing fatigue and, furthermore, improving the capability of taking exercise.
