Abstract The Relationship between Internet Age of Adolescents and Korean Parents-Adolescents Communication Style In-Kon Park (BK21 Research Professor, Sungkyunkwan University) This study analyzed the uses and gratifications of the Internet by Korean adolescents and parents-adolescents communication style. The subjects were 187 adolescents who are attending in a church in Seoul. Factor analysis, t-test, one-way ANOVA, and correlation were employed to analyze the data. The findings of this study were as follows. Factor analysis reduced the variables into 3 categories for the Internet gratifications, and 3 for the parents-adolescents communication styles. All 6 categories are entertainment-escape, information-seeking and surveillance, interpersonal and social communication, positive-communication style, passive- communication style, negative-communication style. T-test showed male students are more oriented for entertainment-escape gratification and passive-communication style than female students. High school students are more oriented for using the Internet in the information-seeking and surveillance purpose than middle school students. One-way ANOVA showed the Internet heavy users used the Internet for entertainment-escape and interpersonal and social communication purpose. Finally, the factors between Internet gratifications and communication styles were correlated to find out their relationships. The results showed positive-communication style group was strongly correlated with information-seeking and surveillance gratification purpose. The passive-communication style group was correlated with entertainment-escape and interpersonal and social communication gratification purpose.

14.6, 60 및 200 A GeV 원자핵-원자핵 중심 충돌 核반응 연구

박인곤,송진섭,남상탁,윤천실 慶尙大學校 기초과학연구소 1989 基礎科學硏究所報 Vol.5 No.-

The results of a study of central collisions of ^16O nuclei with the heavy elements of nuclear emulsion(^107Ag, ^80Br) at 14.6, 60 and 200 GeV/n are compared with proton-emulsion data at equivalent energy. The multiplicity of produced charged secondaries for the ^16O interactions increases with energy faster than for proton projectiles, but the ratio of the mean meson multiplicity to the number of wounded nucleon is reasonably consistent with the prediction of superposition models. At 200 GeV/n, the central particle pseudorapidity density is found to be 66±2 for events with multiplicities exceeding 200.

中性微子에 의해서 核乾板內에 發生한 核反應에 대한 考察(Ⅱ)

朴仁坤,宋珍燮 慶尙大學校 1985 論文集 Vol.24 No.1

To compare and test the various methods of energy estimation, the Ech, Ecast and E(θ) parameter is examined as a function of Nh and n_s by making use of the data of 305 Neutrino jets in muclear emulsion. The method is reliable and the value of Ech give almost a constant, as a function of Nh, but increase as n_s. Its significance is discussed.

Internet Dependency of Korean Students Compared to That of American Students

박인곤 한국기독교교육정보학회 2012 Journal of Christian education information tech Vol.0 No.21

The Internet has influenced on contemporary human lives in various aspects. After the advent of the Internet in 1960’s, the popularity of the medium flourished in 1990’s. One of the Internet's important influences is the tendency of excessive usage. College students are more inclined to immoderate use of the Internet. Due to the excessive usage of the Internet many dysfunctional effects have been shown to the college students in the educational fields. From this cognition the researcher examined college students' Internet dependency of Korean students compared to that of American students. An email survey was conducted and collected from 377 Korean and American university students. It was examined to see how Internet dependent and non-dependent groups were associated with their Internet use. How the Korean and American groups show the differences between Internet dependents and non-dependents was also studied. The results showed that the different demographic variables have different Internet dependencies.

Baseline sensitivity of Scirpus juncoides and Monochoria vaginalis populations to HPPD inhibitors in Korea

박인곤,Mirjalol Umurzokov,Bo Aung Bo,신호영,조광민,박기웅,이증주 한국잔디학회 2022 Weed & Turfgrass Science Vol.11 No.2

The study was conducted to evaluate the baseline sensitivity index (BSI) of Scirpus juncoides and Monochoria vaginalis populations to 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitors, benzobicyclon, and mesotrione and to estimate the potential risk of the HPPD inhibitor resistance in paddy fields in Korea. The seeds of matured S. juncoides and M. vaginalis biotypes were collected from a total of 105 sites and a whole plant dose-response test was performed. Nonlinear fit curve (DoseResp) analysis revealed that GR50 values of S. juncoides biotypes ranged from 9.6 to 16.5 g a.i. ha-1 to mesotrione and 13.1 to 26.4 g a.i. ha-1 to benzobicyclon. BSI was 1.72 and 2.01 for mesotrione and benzobicyclon respectively. The GR50 values of M. vaginalis populations ranged from 10.9 to 16.3 g a.i. ha-1 to mesotrione and 11.7 to 21.1 g a.i. ha-1 to benzobicyclon. BSI was 1.48 for mesotrione and 1.78 for benzobicyclon. No shift in mesotrione and benzobicyclon sensitivity was observed suggesting that these HPPD herbicides can still be used very ffectively to control S. juncoides and M. vaginalis populations in rice fields in South Korea. However, we strongly suggest that constant monitoring and baseline sensitivity studies need to be conducted continuously to detect the evolution of herbicide-resistant weed biotypes.

디지털미디어시대 국내 케이블TV 수신료 제도에 관한 연구

박인곤 ( In Kon Park ),최용준 ( Yong Jun Choi ) 전북대학교 사회과학연구소 2008 지역과 세계 Vol.32 No.1

국내 케이블TV가 등장한지 14여년이 지나고 있는 현재 다채널 유료방송 시장의 판도는 더욱 극심한 경쟁체제로 재편되고 있다. 기존에 케이블방송과의 경쟁에 있던 디지털 위성방송 뿐만 아니라 통신망을 사용하는 방송서비스인 IPTV의 등장은 국내 유료방송시장의 지각변동을 예고하고 있다. 이러한 때에 이 논문은 다채널TV 서비스의 선두주자인 케이블TV의 수신료 제도를 살펴봄으로써 극심한 경쟁이 예상되는 미래의 유료방송시장을 예측해 보고자 하였다. 케이블TV의 매출구조와 수익구조를 통하여서 지난 14년간 국내 케이블TV 산업구조를 살펴보았으며 국내 케이블TV가 가지고 있었던 고질적인 문제점인 수신료 제도의 문제점을 신문가격추이, 디지털 위성방송 매출액 추이 등을 통하여서 알아보았다. 국내 케이블TV 수신료 문제점의 해결방안으로 디지털 전환에 따른 수신료 정상화 및 다양한 티어 및 번들링을 통한 가입자 확보 및 이탈방지에 대하여도 살펴보았다. 결론에서는 국내 케이블TV 산업의 발전과 경쟁력강화에 대한 거시적인 방안들을 제시하였다. Since the cable TV in Korea has been introduced in 1995, the multichannel broadcasting industry has been competed. The industry will be expected to be more and more competed as long as the IPTV that uses telecommunication network for serving interactive broadcasting service than the digital satellite broadcasting service. Considering current situation, this paper tried to analyze the cable fee systems and compare the systems of other services in order to forecast the development of the multichannel broadcasting service industry. For achieving the purpose of this paper, cable TV`s revenues and profits of last 14 years have been analyzed and then fees system that has been pointed at the chronic problems was compared to newspaper fee and other fees of digital satellite broadcasting service. The paper suggested that cable TV fees should be increased at reasonable level that cable subscribers would accept with cable TV`s digital switchover. Also cable TV operators should serve various tiers and bundling service in order to compete with other multichannel services prohibiting cable subscribers not to transfer. In conclusion, the paper proposed the macroscopic solutions for strengthening competitive power against other media services and ore and further developing the industry.

中性微子에 의해서 核乾板內에 發生한 核反應에 대한 考察(Ⅰ)

朴仁坤,宋珍燮 慶尙大學校 1984 論文集 Vol.23 No.2

Experimental dat are presented on charged particle multiplicities production and angular distribution in interactions of neutrino with emulsion nuclei. Correlation were established and the obtained parameters of multiplicity distribution compared with those obtained from proton-nucleus interaction and π- mesion-nucleus interaction data. Angular distributions of charged secondaries of nuclear interactions produced by neutrinos in emulsion, have been studied. The average of <η(θ)>, <<η(θ)>>, as a function of ns, were fitted by a least-square method to a formular, A+B/n, where n is the total number of secondaries in a event estimated from ns with several plausible assumptions. The standard deviation of η(θ) distribution, <σ>, does not seem to depend on ns.
