박현섭 ( Hyun Sup Park ),홍성애 ( Seong Ae Hong ) 대한보건협회 2020 대한보건연구 Vol.46 No.3

연구목적 : 본 연구는 남ㆍ녀 청소년의 자살생각에 영향을 미치는 요인의 차이를 파악하고자 시도되었다. 연구방법 : 본 연구는 2019년 청소년건강행태온라인조사 원시자료를 활용하였다. 사용된 데이터는 가중치가 적용된 복합표본 분석으로 SPSS Ver. 25.0 프로그램을 이용하여 분석하였으며, 최종 분석 대상은 55,748명이었다. 연구결과 : 남학생 9.3%, 여학생 17.4%가 자살생각을 경험한 곳으로 밝혀졌다. 남학생의 자살생각에 가장 큰 영향 변수는 우울(OR=5.61)이며, 폭력 피해경험(OR=2.35), 스트레스(OR=2.08), 친척집 거주(OR=1.99), 약물경험(OR=1.92), 성경험(OR=1.35), 음주경험(OR=1.27), 주관적 건강 인지(OR=1.27), 기숙사 거주(OR=1.26), 경제만족도(OR=1.17), 수면만족도(OR=1.14), 연령(OR=0.88), BMI(OR=1.07) 순으로 나타났다. 반면, 여학생의 자살생각에 영향을 주는 가장 큰 영향 변수는 우울(OR=4.77)이며, 약물경험(OR=4.13), 폭력피해경험(OR=2.27), 스트레스(OR=2.06), 성경험(OR=1.63), 흡연경험(OR=1.37), 음주경험(OR=1.32), 주관적 건강 인지(OR=1.31), 연령(OR=0.83), 경제상태(OR=1.11), BMI(OR=1.11), 수면만족도(OR=1.10), 학업성적(OR=1.06) 순으로 나타났다. 결론 : 남ㆍ녀 청소년의 자살생각에 미치는 영향 요인에 차이가 있는 것으로 밝혀졌으므로 차별화된 개입과 중재전략이 필요하다. Objectives: This study attempted to determine the difference in factors affecting the suicidal ideation by gender among adolescents. Methods : This study used data from the 15th Korea Youth Risk Behavior Web-based Survey(2019) of the Korea Center for Disease Control and Prevention(KCDC). The data used were analyzed using the SPSS Ver. 25.0 program as a weighted composite sample analyse. Results : 9.3% of male students and 17.4% of female students were found to have experienced suicidal ideation. Male students' ideation of suicide were influenced by depression (OR=5.61), experience of violence (OR=2.35), stress (OR=2.08), relative residence (OR=1.99), drug experience (OR=1.92), sexual experience (OR=1.35), drinking experience (OR=1.27), subjective health recognition (OR=1.27), dormitory residence (OR=1.26), economic unsatisfaction (OR=1.17), sleep unsatisfaction (OR=1.14), age (OR=0.88) and BMI (OR=1.07). On the other hand, female students' ideation of suicide were influenced by depression (OR=4.77), drug experience (OR=4.13), experience of violence (OR=2.27), stress (OR=2.06), sexual experience (OR=1.33), smoking experience (OR=1.32), drinking experience (OR=1.32), subjective health recognition (OR=1.31), age (OR=0.83), economic unsatisfaction (OR=0.83), BMI (OR=1.11), sleep unsatisfaction (OR=1.10), and academic performance (OR=1.06). Conclusions : It has been found that there are differences in factors that affect between male and female students' suicide ideation, so differentiated intervention and mediation are needed.

박현섭 ( Hyun Sup Park ),홍성애 ( Seong Ae Hong ) 대한보건협회 2021 대한보건연구 Vol.47 No.4

연구목적 : 본 연구는 노인의 성별 미충족 의료 경험에 영향을 미치는 요인을 비교하고자 시도되었다. 연구방법 : 본 연구는 한국의료패널 2017년 연간데이터(Version 1.6)을 활용하여, 3,886명을 최종 대상으로 SPSS Ver. 27.0 program을 사용하여 분석하였다. 결과 : 남성 노인은 8.6%, 여성 노인은 12.4%가 미충족 의료를 경험하였다. 남성 노인은 문제음주를 경험한 경우(AOR=2.861), 스트레스 수준이 높을수록(AOR=2.019), 자가 이외인 경우(AOR=1.986), 주관적 건강 상태가 나쁠수록(AOR=1.498) 미충족 의료를 경험할 확률이 높았고, 소득 1분위보다 소득 4분위(AOR=0.377), 소득 2분위(AOR=0.382)인 경우 미충족 의료를 경험할 확률이 낮았다. 여성 노인은 스트레스 수준이 높을수록(AOR=1.902), 배우자 없는 경우(AOR=1.769), 현재 경제활동을 하는 경우(AOR=1.460), 주관적 건강 상태가 나쁠수록(AOR=1.262) 미충족 의료를 경험할 확률이 높았고, 삶의 만족도가 높을수록(AOR=0.129), 소득 1분위보다 소득 5분위(AOR=0.577), 소득 3분위(AOR=0.599), 소득 2분위(AOR=0.603)인 경우 미충족 의료를 경험할 확률이 낮았다. 결론 : 노인의 미충족 의료 경험은 성별에 따라 다른 양상을 보이므로 성별에 따라 선별적 강화 중재 전략이 필요하다. Objectives : The objective of this study is to identify the factors to influence the unmet healthcare needs in Korean elderly according to gender. Methods : This study used data from the Korea Health Panel Survey of 2017(KHP 2017) of the Korea Institute for Health and Social Affairs and the National Health Insurance Service. The data used were analyzed using the SPSS Ver. 27.0 program. Results : 8.6% of male elderly and 12.4% of female elderly were found to have experienced unmet healthcare needs. For male elderly, the probability of experiencing unmet healthcare needs was higher in having problem by drinking(AOR=2.861), the higher level of stress(AOR=2.019), not having own house (AOR=1.986), the worse self-rated health(AOR=1.498). The probability lower in the 4th income quintile(AOR=0.377), the 2nd income quintile(AOR=0.382) than the 1st income quintile. For female elderly, the probability of experiencing unmet healthcare needs was higher in the higher level of stress(AOR=1.902), not having spouse(AOR=1.769), doing economic activity(AOR=1.460), the worse self-rated health(AOR=1.262). The probability lower in the higher life satisfaction(AOR=0.129), the 5th income quintile(AOR=0.577), the 3rd income quintile(AOR=0.599), the 2nd income quintile(AOR=0.603) than the 1st income quintile. Conclusions : Factors influencing Korean elderly’ unmet healthcare needs differed between male and female, so differentiated intervention and mediation are needed.

광대역 디지털 통신용 저왜곡 전력 중폭기 설계

박현섭,김수경,구경헌 한국항행학회 1998 韓國航行學會論文誌 Vol.2 No.2

최근의 이동 통신 시스템용 전력 증폭기는 고전력, 고효율 특성을 가지며 또한 저왜곡 특성을 갖도록 요구되고 있다. 디지털 통신 시스템의 전력 증폭기는 상호 변조와 스펙트럼 재성장에 의한 인접 채널 간섭이 생기게 되며, 특히 광대역 디지털 통신 시스템에서는 인접채널 전력비 특성이 중요하게 이용되고 있다. 전력 증폭기의 통신 시스템에 대한 영향을 분석하기 위해 22Mcps로 대역 확산된 광대역 디지털 변조 신호원을 구현하고, ISM 밴드를 이용한 전력 증폭기를 설계하여 RZ, NRZ등 코딩방법에 따른 전력 증폭기의 비선형 특성인 인접채널 전력비 특성을 비교 시뮬레이션 및 측정하였다. Most of modem mobile communication systems require low distortion in addition to high power and high efficiency characteristics for power amplifiers. The power amplifiers cause adjacent channel interference by intermodulation and spectral regrowth. In order to analyze the effects of the power amplifier on communication system, a 22Mcps spreaded digital modulated signal source and a ISM band power amplifier have been constructed, ACPR characteristics are simulated and measured for the RZ and NRZ encoded signals.

김경지,박현섭 경희대학교 체육대학 한국체육과학연구소 2004 體育學論文集 Vol.32 No.-

It is the purpose of this research that finds on solution, one of the efforts to seek for the improvement and secure the base about improving the judgement of Taekwondo, to disentangle a complicated matter which remains in a sports fields, with a method which find out the referees'(the one) and coaches'(the other) understanding and opinion about those subjects above mentioned. The target of this study is the permanent referees, 65 persons, who participated in the national team elimination match and the outstanding coaches, 65, who already have many players taken part in the game. In advance, I made a questionnaire with the help from existing studies, asked a professor of the Taekwondo department, the head of referee committee, a coach of the national team, and an officer of the associates to examine, modified and wrote it down. The confidence of it recorded 99.2%. I took statistics respectively on percentage, the maximum frequency, average, and so on Chi square and T-test are used for the analysis of the differences between the two groups. After operating these, I get some conclusions. 1) There is a big difference between the two groups' on the accuracy and justice that Taekwondo match has. 2) Referees see present judgement getting better, coaches don't. 3) The two groups(the one and the other) don't trust each other so that each members can get stresses at the worst. 4) To develope the quality of the judgement in match, the think best to reduce a trend of mutual distrust and make their performance higher. On the contrary, the others assists that the referees competence and educational system should be in priority. 5) According to the two, they all take the misjudgement for granted when winning and leading take place. 6) Also the big difference between the two groups' opinion occurs in the winning and leading. 7) The one doesn't think that the import of the graded score system has an impact on the improvement of the judgement but the other does. 8) The one regards existing criteria in judging "leading" as good but the other doesn't. 9) The coaches think of a warning judgement and a penalty count system as being used for the unfair judgement but the referees are in the opposite. 10) the referees think that the import of the supervisor system doesn't have an effect on the correctness and fairness in the match but the coaches don't think so.
