  • 초기후두암에 있어서 보존적 술식의 장점은 후두 전적출술시와 같은 국소치료효과를 얻을 수 있으면서도 후두의 생리적 기능을 최대한 보존하는데 있다. 성공적인 후두부분절제술을 위해서는 후두내에서 종양의 발생위치 및 그 확산에 대한 연부조직들의 해부학적 역할에 대한 이해가 필요하다. 과거에는 초기후두암환자에서 정상적인 목소리를 보존할 수 있다는 이점 때문에 방사선 치료가 일차적 치료요법으로 많이 시행되어 왔다. Wang 과 Wong은 성대 막양부에 국한된 병변에서 방사선치료에 대한 5년간 조절율(5-year control rate)이 92%, 전연합부를 침범한 경우가 81%, 그리고 후방으로 전파된 경우 76%로 감소된다고 보고하였다. Olofsson 등은 전연합부를 침범한 57례의 환자에서 방사선 치료를 시행하여 85.7%의 5년 생존율을 얻었으나, 57례중 15례에서 재발하여 구제수술(salvage surgery)을 시행하였고, Jesse 등$^{13)}$ 은 전연합부를 침범한 91례의 T1, T2 성문암을 방사선 치료를 시행하여 8.8%의 실패율을 보였으나 22례의 환자에서 재발하여 후에 salvage surgery를 시행하였다. 그러나 Ogura 등은 피열 연골을 침범한 79례의 환자에서 보존적 수술을 시행한 결과 6례의 환자에서 재발하여 90%의 3-years control rate를 얻을 수 있었다고 보고하였다. 이처럼 병변이 전연합부, 피열연골 혹은 후방성문하부로의 침범이 있는 경우는 방사선 치료 효과가 떨어지고, 따라서 방사선 치료에 실패할 가능성이 보다 높기 때문에 비록 방사선 치료 후 실패한 경우에서 구제 수술을 시행할 수는 있지만 후두기능을 보존하려는 궁극적인 목표를 생각할 때 보존적 수술을 우선적으로 시행하는 것이 바람직하다고 할 수 있다. Biller 등은 방사선 요법에서 실패한 성문부 종양에서는 대부분 전적출술을 시행하지만 일부는 보존적 수술을 시행할 수 있다고 보고하였다. 이들은 반대측 성문부에 종양의 침범이 없어야 하고, 전연 합으로의 파급은 있어도 가능하며 성대돌기를 제외한 피열연골이 정상이어야 하고, 종양의 성문하부로의 파급이 5mm 이내라야 하며, 연골에 침범이 없어야 하고, 성대고정이 없어야 하며, 재발 병소가 방사선요법 전의 원발병소와 상관관계가 있어야 하며, 원발병소가 후두부분적출술에 합당할 경우 보존적 술식을 시행할 수 있다고 하였다. 최근에는 다양한 후두 재건술의 발달로 보다 진행된 후두암에 대한 보존적 후두절제술들이 소개되고 있다. 단측 T3,T4 후두암 혹은 경성문암, 이상와에 위치한 암의 경우 음성만을 재건하는 후두근적출술 (near total laryngectomy)을 시행하기도 한다. 본원 이비인후과에서 1986년부터 초기성문암 51례 중 24례(47.1%)와 초기성문상암 17례 중 12례 (70.6%)에 대하여 보존적 술식을 시행하였다. 초기 성문암의 보존적 술식을 시행한 24례중, 2례(8.3%)에서 경부재발, 1례(4.2%)에서 경부재발과 동반된 폐의 원격전이가 있었으나 원발부위의 재발은 관찰되지 않았고, 술후 합병증으로 1례(4.2%)에서 후두협착, 3례(12.5%)에서 수술부위의 육아종형성, 그리고 1례(4.2%)에서 기관지염이 발생하였으나 오연으로 인한 폐렴은 발생하지 않았다. 초기성문 상암의 보존적 술식을 시행한 12례 중 1례(8.3%)에서 원발병소의 재발, 2례(16.7%)에서 경부재발이 있었으며, 술후 합병증으로 3례(16.7%)에서 오연으로 인한 폐렴의 발생이 있었지만 다른 합병증은 발생하지 않았다. 초기성문암 24례 중 재발이 나타난 3례의 환자를 제외한 21례(97.5%)와 초기성문상암 12례 중 재발이 나타난 3례의 환자를 제외한 9례 (75%)에서는 현재까지 재발소견을 보이지 않고 있다. 이러한 결과는 다른 보고자들과 유사한 결과를 보이고 있지만 아직까지 증례가 많지 않기 때문에 생존율을 얻기에는 미흡한 점이 있으며, 향후 지속적인 추적관찰이 필요할 것으로 사료된다.

  • This study aims to explore social participation needs among the elderly in Korea from the perspective of the elderly participant's. 40 Q-samples are drawn from the Q-population including attitudes and needs toward social participation in later life based on news articles, essays, research, documentary, and television shows. 35 subjects are analysed by the QUANL program and the types of social participation needs are divided into four patterns which accounted for 60.16% of the total variance. The elderly's portrayal of an ideal social participation is about making independent decisions and being able to actively participate in the activities they chose to do. However, their most undesirable scenario would be being confused and uncertain of what they should do the remainder of their lives. The needs of social participation among the elderly varies on four indicators such as ego, social capital, life satisfaction, life vitality and these four indicators have two sub-categories with a total of 8 types of classification. These 8 types differ by priorities, adaptation to life changes, motivation to social participation, and desired activity. Findings suggest that researchers and policy makers need to consider service user perspective on social participation in later life, not service provider perspective.

  • With the broader range of information and communications technology, of which fashion is a foundational medium, to analyze fashion as an information technology in order to better understand the industry's desire for intellectual property protection, popular resistance to such protection, and the most efficacious balance between them in terms of creative expression. It is, therefore to be focused on cultural and historical reasons for the limited degree of intellectual property protection extended in the past to certain categories of human creativity, including fashion design. So, the question of why some tension still exists between creators and consumers of fashion, how information theory can contribute to an explanation for that tension, and what role law can play in its resolution with Louboutin case and Levi case. Consumers and designers alike are better served by promotion of fair competition, lower litigation costs, and the inventive synergy of the fashion industry. Louboutin shows the comfortable, respectful limits of trademark law, while Levi illustrates the dangerous, overreaching deference that a few circuits have granted to famous marks. The Supreme Court could clarify the standard for dilution claims, requiring that a junior mark be "identical or nearly identical" or even "significantly similar" to a senior mark. Courts should need a deference in making dilution determinations and can choose to make this factor quite subjective with the highest degree of similarity.

  • Li-Gu was a Confucianist who criticized traditional 'attend to Righteousness and neglect Profit' idea and insisted that people affirmed 'Proprietiy' and 'Interest', which accorded with human nature and desire. He said that 'Proprieties' was made by adjusting one's material life and natural desire. Therefore, if we want 'Propriety' is manifested itself, we must affirm and satisfy the material life and natural desire first. He asserted that if we didn't follow this, the people's life would be devastated and the nation would face a big crisis. Li-Gu's thought not only gave Wang An Suk's Reformation a theoretical basics, but also attached the new and reformist meanings to 'Propriety', which had been changing meaningless and abstract, by criticizing Songming Confucian School and put great stress on uniting the inside and outside. In this article, through examining Li-Gu's the idea of Righteousness and Profit, King and Ruler, Inside and Outside, we can consider what the real 'Propriety' is and what kind of practical meaning 'Propriety' has.

  • The followings are the characteristics of Kyunghakkwan of Youngjae Oh Yunsang. First, he delves into Soju (小注: Small notes or commentaries) of Saseo-Jibju-Daejeon (四書集註大全: Compendium of the Commentaries of Four Confucius Canons). Frequently adding, "thinking," "thinking again," he enumerates his own theories critical of various scholars who left commentaries in Daehak-Janggu-Daejeon (大學章句大全: Compendium of the sentences and phrases in Daehak, one of the canon) and Jungyong-Janggu-Daejeon (中庸章句大全: Compendium of the sentences and phrases in Jungyong, another canon). Secondly, he quotes theories of Korean confucius scholars. Besides Lee Yulgok, he introduces mainly theories of Nongam Kim Changhyub and Namdang Han Wonjin. Thirdly, he researches into various canons. He diverts from the general trend of Chosun confucius studies which focuses on Saseo and explores Seokyung (書經: One of Five canons of Chinese Confucius Studies and the oldest history book). Fourthly, his Kyungseol, especially that of Jungyong, was recognized and accepted by his contemporary Giho School scholars. Finally, he shows skepticism even on Confucius's own ideas and begs to differ.

  • Companies actively engage with the public through social media to enhance sales and promote brand awareness, which was further encouraged by the pandemic. However, previous studies tend to consider companies as a group of identical features. This study focuses on the differences between B2B and B2C companies' social media content strategy in relation to user engagement. This study categorized KOSPI 100 companies that manage Facebook corporate fan pages into B2B and B2C, and then analyzed the contents they posted from January 1 to December 31, 2020. The result showed that B2C companies tended to use videos over images, prefer hashtags, and comment its product name more often compared to B2B companies. B2B companies preferred images, used more hyperlinks, and mentioned its company name more often. In B2B companies, images and length of text had positive effects on user engagement, while hyperlink and URL had negative effects. B2C companies' text length had positive effect on user engagement. This study provides practical implications to PR practitioners for establishing a social media strategy which enhances user engagement.

  • In this study, the conditions of low temperature and high pressure of biogas upgrading process using polysulfone membrane have been designed and tested to achieve the high recovery and efficiency corresponding to those of the highly selective polymeric materials. Polysulfone hollow fiber membrane with 4-component dope solution was spun via non-solvent induced phase separation. The hollow fiber membrane was mounted into a 1.5 inch housing. The effective area was 1.6 m2, and its performance was examined in various operation temperatures and pressures. CO2 and CH4 permeances were 412 and 12.7 GPU at 20℃, and 280 and 3.6 GPU at -20℃, respectively, while the CO2/CH4 selectivity increased from 32.4 to 77.8. Single gas test was followed by the mixed gas experiments using single-stage and double stage where the membrane area ratio varied from 1:1 to 1:3. At the single-stage, CH4 purity increased and the recovery decreased as the stage-cut increased. At the double stage, the area ratio of 1:3 showed the higher CH4 recovery as decreasing the operation temperature at the same purity of CH4 97%. Finally, polysulfone hollow fiber membranes have yielded of both CH4 purity and recovery of 97% at -20℃ and 16 barg.

  • As an effort to further extend the existing understanding on the Psychology of Working Theory, this study examined gender differences in the paths to the attainment of decent work with Korean emerging adults. A total of 311 South Korean employees (mean age = 25.96, men = 94, women = 217) completed online questionnaires. We found that economic constraints inversely predicted work volition and career adaptability, which were positively relatedin turn, led to decent work. The overall indirect effect of work volition and career adaptability between economic constraints and decent work was significant., hHowever, the specific indirect effect of work volition and career adaptability was not significant. Further analyses showed a gender difference in the paths. Specifically, economic constraint was significantly negatively associated with work volition, and work volition predicted decent work only for women, but not for men. Moreover, economic constraint was significantly inversely associated with career adaptability, and career adaptability positively predicted decent work only for men, but not for women. Work volition mediated between economic constraints and decent work for women, while career adaptability had a mediating effect for men. It suggests that career resources for obtaining a decent work may be distinctive by genderdifferent groups.

  • Statement Validity Analysis (SVA) is utilized in criminal investigations and the court to assess the credibility of given statements. During this procedure, the criteria for Criteria-Based Content Analysis (CBCA) are used to evaluate whether statements include the characteristics reflecting actual experiences about the event in question. Various studies had been conducted on the efficacy (classification rates) of CBCA criteria, yet the consistency of the findings was not investigated. In the current study, a meta-analysis was conducted with Korean CBCA studies reported from 2004 to 2020 (a total of fourteen studies). As a result, the total score of CBCA was found to successfully discriminate truth and fabrication. A significant positive (+) effect size was found with four criteria (3, 4, 10, and 12), all of which are classified as cognitive criteria. However, contrary to the underlying assumption for CBCA, criterion 18, classified as one of the motivational criteria, showed a significant negative (-) effect size. Meanwhile, moderator analyses were possible for eleven criteria (2~9, 12, 13, 15) and the results showed the significant effects of potential moderator variables such as the gender and status of the participants, study types and designs, number of raters, and publication status. The current results suggests that more careful attention is required to each criterion-especially the cognitive criteria-rather than the total CBCA score as well as the possible moderator effects in order to assess truthfulness of the statements. The implication, limitations, and suggestions for future studies were discussed.
