이명진,윤기현,전애경,이지영 한국세라믹학회 2004 한국세라믹학회지 Vol.41 No.6

TiO2, SiO2, and PBA(pseudo boehemite alumina) sol were prepared by sol-gel process. The particle sizes of these sol exhibited uniform 10~30 nm. As the amount of SiO2 sol increased, the temperature of phase transition (from anatase phase to rutile phase) was raised temperature than 600 oC, which attributed to the enhanced photocatalyst properties. Also, the anatase phase was obtained with very small amount of the rutile phase from the addition of SiO2 (10 - 30 wt.%) at annealing temperature of 1200 oC. The specimen with 20 wt. % SiO2 sol exhibited the maximum photocatalyst properties. But, the specimen with PBA sol did not affect photocatalytic activity due to the presence of rutile phase. 졸겔 공정으로 안정한 TiO2, SiO2, PBA(pseudo boehemite alumina) 졸을 제조하였다. 제조한 졸 용액은 비교적 균일한 10~30 nm의 입자크기를 나타내었다. TiO2 졸에 SiO2 졸의 첨가량이 증가함에 따라, anatase 상에서 rutile 상으로 전이되는 상전이 온도를 600 oC 이상으로 증가시켜 광분해 특성을 향상시켰다. 또한, TiO2 졸 용액에 SiO2 졸을 10~30 wt.% 첨가하여 1200 ℃ 이상의 고온 소성 후에도 anatase 가 주된 상으로 소량의 rutile 상이 관찰되었다. 또한 SiO2 20 wt.% 첨가시, 최대의 광분해 특성을 나타내었다. 그러나, PBA 졸의 첨가는 첨가량에 관계없이 광분해 특성에 영향을 주지 않았다.

전산보안시스템 구축체계에서 수집한 디지털증거의 원본성 증명에 관한 연구

이명진,이병엽 한국콘텐츠학회 2023 한국콘텐츠학회논문지 Vol.23 No.8

전산보안시스템은 디지털 장치의 매우 중요한 시스템 중 하나이다. 전산시스템에 저장된 많은 디지털 자료들이 부당하고 위법하게 사용되는 것을 방지하는 중요한 시스템이라 할 것이다. 이에 기업들은 전산보안시스템 구축에 많은 비용과 노력을 기울이고 있다. 전산보안시스템은 기업의 특성에 맞게 발전되었고 기업들이 내부적으로 규정한 절차대로 기업에서 생산하는 디지털 자료가 여러 보안시스템을 거치게 되었다. 하지만 디지털 포렌식 조사에서는 기업의 전산시스템의 발전이 디지털증거의 수집이나 분석하는 것에 어려움이 될 수 있다. 현재 선별이라는 방법으로 디지털증거를 수집하고 있으나 선별수집에 앞서 전산보안시스템의 구축은 디지털증거의 원본의 기준이 모호해지는 문제가 발생한다. 이에 본 논문에서는 기업의 전산보안시스템의 구축체계에서 디지털증거의 기본원칙인 원본의 수집에 있어 원본의 기준을 실무적으로 명확히 하는 디지털증거의 수집 방안을 제시해 보고자 한다.

이명진,이원창,Kwon Young Hwan 한국항공우주의학협회 2022 항공우주의학회지 Vol.32 No.3

Purpose: Zika virus (ZIKV) infection is a mosquito-borne Flavivirus disease. we investigated the epidemiological aspects and status of imported ZIKV infection cases in Korea (Republic of) and Japan during 2016–2020. Methods: Raw data of ZIKV infection cases from the Korea Diseases Control and Prevention Agency, and the National Institute of infectious Diseases in Japan, 2016– 2020. Results: There were 33 cases of ZIKV infection in Korea and 21 cases in Japan between 2016 and 2020. Cumulative incidence rate per 1,000,000 overseas travelers (OTs) of Korea (0.30) did not substantially differ that of Japan (0.27), respectively. We observed the ZIKV infected cases of male (69.7% of total cases) were much more than that for female (30.3%) in OTs of Korea (P<0.05). However, while there was none significant differences level between males (52.4%) and females (47.6%) in OTs of Japan. On the other hands, the distribution by adjusted-age groups for ZIKV infections were similar between Korean and Japanese that total cases occurred in the over 20 to 59-years old age, clearly more showing a higher infected of ZIKV (P<0.01). The presumptive origin imported ZIKV infection cases in Korean were as follows; Southeast Asia (81.8% of total cases) and Central & South Americas (18.2%), and those in Japan, these were Southeast Asia (42.9%) and Central & South Americas (42.9%) and Oceania (4.7%), respectively. Conclusion: This study demonstrates that there is a similar pattern of imported ZIKV disease cases in Korea and Japan. Therefore, to prevent ZIKV infections, greater attention should be paid to individuals who are planning to travel to the presumptive regions of ZIKV.

Temporal Variation in the Strength of Educational Assortative Marriage in Korea: A Birth Cohort Analysis of the 2000 Korea Census

이명진 서울대학교 사회발전연구소 2010 Journal of Asian Sociology Vol.39 No.1

This paper investigates the trend in assortative marriage with respect to education among a large Korean cohort born in the 1930s to the 1970s. The two-percent sample data from the 2000 Korea Census is used to investigate changes in the association between couples’ educational attainment across different time periods. The primary assumption of this study is that status distance inhibits social association such as friendship and marriage. With increasing difference in status between individuals, the rate of social association among individuals is negatively correlated to status difference. Being one of the most important associations, this would suggest that marriage becomes less frequent with increasing status distance between potential spouses, thus producing assortative marriage with respect to social status. Various types of log-linear models and L2 (likelihood ratio chi-square)-distance measures are used to analyze the temporal change of educational assortative marriage in this paper, and the main findings are as follows. First, with Korea’s rapid economic growth since the 1960s, earlier birth cohorts show an increase in educational assortative marriage. Korea’s unique historical experiences appear to heighten the importance of achieved status, such as educational attainment, as a new basis for social hierarchy. Second, educational assortative marriage decreases among later birth cohorts. However, this decrease does not necessarily tend to increase general social openness because new types of status base, such as family background, emerge and gain increased importance in marriage selection in line with increased stability of social stratification.

이명진,채원식,서진교,박종완 한국패류학회 2009 The Korean Journal of Malacology Vol.25 No.3

Optical properties and color analysis of nacreous layers were performed using various pearl shells. The cross section and microstructure of the surface in each nacreous layers were observed through a SEM (Scanning Electron Microscope), and the diffraction pattern on SEM images was analyzed using FFT (Fast Fourier Transform). Through these analysises, it was verified that the color and optical characteristics are closely related to the structure of nacreous layers. Incident angle-dependent reflection spectrum was used to examine the phenomena of color differenceas the direction of observation. Quantified values on the color change were obtained by CIE L*a*b* color scale. Using this research, database for the characteristics of natural pearl shells can be established, and the precise analytic method for observation of pearl shells was suggested.

Use of NTrapⓇ during Ureteroscopic Lithotripsy for Upper Ureteral Stones

이명진,이승태,민승기 대한비뇨의학회 2010 Investigative and Clinical Urology Vol.51 No.10

Purpose: This study aimed to determine the value of the NTrapⓇ (Cook Urological INC, USA), which was designed to block the upward movement of stones during ureteroscopic lithotripsy. Materials and Methods: We reviewed the data of 144 patients who underwent ureteroscopic lithotripsy for an upper ureteral stone from June 2006 to May 2010. Sixty-eight patients who underwent ureteroscopic lithotripsy without the use of the NTrapⓇ were assigned to Group I and 76 patients who underwent ureteroscopic lithotripsy with the NTrapⓇ were assigned to Group II. The size of the stones, operation time, success rate, and pre- and postoperative complications were compared retrospectively between the two groups. Results: The mean age of the patients (Group I: 35.8 years; Group II: 32.6 years) and the sex ratios were not significantly different between the two groups. The mean size of the stones was 6.9 mm and 7.4 mm, which also was not significantly different between the two groups. The mean operation time was 82.7 minutes and 78.7 minutes. The operation time was shorter in Group II, but the difference was not significant. The success rate of stone removal was 89.7% and 98.7% in Groups I and II, respectively; Group II showed a significantly higher success rate. Two cases of ureteral perforation and one case of ureteral avulsion occurred in Group I, and one case of ureteral perforation occurred in Group II. Conclusions: NTrapⓇ, which is an instrument used to assist during ureteroscopic lithotripsy, can be considered to be an effective tool that blocks the upward movement of the stone and aids in safe stone removal.

동해안 김동언 <심청굿>의 판소리 수용과 변화 연구

이명진 판소리학회 2013 판소리연구 Vol.36 No.-

This paper has examined the relationship between and Pansori in terms of the performance of exorcism and its transmission process by setting <Simcheonggut> as the target. <Simcheonggut> is one of the exorcism materials performed as ‘Donghaean-Byulsingut’. A considerable portion of <Simcheonggut> is similar to the details of <Shimchungjeon> which is a fiction of Pansori series and most of the epic details have been accommodated. The author has focused on the relationship between Pansori and <Simcheonggut> even more while especially trying to examine the awareness of Shaman toward Pansori and changes in the process of its accommodation. <Simcheonggut> material is the one performed by a female Shaman named ‘Kim Dong-Eon’ who is an assistant instructor on the education to transmit Donghaean-Byulsingut. Today, ‘Kim Dong-Eon’ is getting attention as the main character of Shaman narration performance among the Shamans performing Donghaean- Byulsingut throughout all areas including Busan, Yeongdeok, Uljin and Gangneung. As a result, the fact that <Simcheonggut> and Pansori have a great deal of relationship could be verified. In case of the texts, it has developed by accommodating the Pansori series fictions while Pansori vocal sound and rhythm were also being used in <Simcheonggut> here and there. Especially in the East coast area of Gyeongsang-do Province, Pansori has been enjoyed as popular art from the time before <Simcheonggut> was actively performed; then Pansori was getting considerably influential during the time of performing <Simcheonggut> on a full scale. However, the distinctive feature of <Simcheonggut> is that Pansori is accommodated based on language and music of the region. Naturally, while the tendency of getting to accept more of musical characteristics of <Shimchungga> is also shown as people can easily encounter Pansori as the society has developed gradually, its originality aspect is still worthy of recognition. The originality of east coast Shamans has even enabled the transitional accommodation of Pansori beyond language and music of the region. Even if it might be the same contents, even the creation of changing the rhythm or adding rhythm to new test such as Shim-Cheong dress up is being performed. This shows even the possibility as creative Pansori which is being attempted a lot today. 이 논문은 <심청굿>을 대상으로 하여 굿의 연행과 전승 과정 측면에서 판소리와의 연관성을 살폈다. <심청굿>은 동해안별신굿에서 연행되는 굿거리 중의 하나이다. <심청굿>은 판소리계 소설인 <심청전>의 내용과 상당부분 유사하고, 서사 내용 전체가 거의 수용되어 있다. 필자는 판소리와 <심청굿>의 관계에 더욱 주목하고, 특히 판소리에 대한 무당의 인식과 그를 수용하는 과정에서의 변화를 살펴보고자 하였다. <심청굿> 자료는 현재 동해안별신굿 전수조교인 김동언 무녀가 연행한 것이다. 김동언은 오늘날 부산, 영덕, 울진, 강릉 등 전역에 걸쳐 동해안별신굿을 연행하는 무당 중에서도 서사무가 연행의 대표적인 인물로 주목 받고 있다. 그 결과 <심청굿>과 판소리는 상당히 많은 연관성을 지니고 있음을 확인할 수 있었다. 사설의 경우에는 판소리계 소설을 수용해서 발전하였고, 판소리 성음과 장단 역시 <심청굿>의 부분 부분에 활용되고 있었다. 특히나 경상도(동해안) 지역에서는 <심청굿>이 활발하게 연행되기 이전부터 판소리가 인기 있는 예술로 향유되고 있었고, <심청굿>을 본격적으로 연행하게 된 시기에는 판소리의 영향력이 상당히 미쳐지고 있었음을 확인할 수 있었다. 하지만 <심청굿>은 지역의 언어, 음악을 기반으로 하면서 판소리를 수용하고 있다는 점이 특징적이다. 물론 점차 사회가 발전하면서 판소리를 쉽게 접할 수 있게 되어 <심청가>의 음악적 특성을 더 많이 받아들이게 된 경향이 보여 지기도 하지만, 여전히 그 독창적인 부분은 인정할만하다. 동해안 무속인들의 독창성은 지역의 언어와 음악을 넘어 판소리의 변화적 수용도 가능하게 하였다. 같은 내용이라고 하더라도 장단을 변화시킨다거나, 심청 옷치레와 같은 새로운 사설에 장단을 붙이는 창작까지 하고 있다. 이는 오늘날 많은 시도가 되고 있는 창작판소리로서의 가능성까지 보여주고 있다.
