The purpose of this study is to improve some problems of the country-of-origin labeling based on the perception of consumers. For this, we surveyed 636 people. The questions of the survey are largely divided into three categories; 1) criteria and subject for imposition of fine, 2) the possibility of getting consumers confused with the products using domestic regional names as domestic products, 3) criteria for the country-of-origin transplantation of agricultural products and forestry products. According to the results, more than 30.0% of consumers preferred that it is adequate for imposing fine as much as its total sales, regardless of the type of business. In addition, in the case of products using domestic regional names, consumers can be confused about the products with domestic ones, even though there is a standard for confusing country-of-origin labeling. Standard for changing the country-of-origin of agricultural, forestry products and livestock, fisheries products are not balanced. The results of this study can be used as basis data for revising the country-of-origin labeling.

SNAKE 프로토콜 설계에 관한 연구

임건우 광주대학교 산업기술연구소 1992 論文集 Vol.1 No.-

SNAKE (System Network Architecture for Korean Ether)는 새로운 PC LAN 시스템에 대한 제안이다. 즉, SNAKE의 목적은 IBM 혹은 유사한 PC 기종간의 네트웍을 효율화하는 LAN 환경을 제시하는 것이다. SNAKE의 구조는 물리적으로는 버스이지만 논리적으로는 슬롯을 갖춘 링의 구조를 갖는다. SNAKE는 2벌의 동축케이블을 사용하여 양방향으로 메세지를 전할 수 있도록 고안하였다. 즉, 두벌의 케이블 중 하나는 어느 한쪽 방향으로만 메세지를 보내는 베이스밴드 방식이다. 이 방법은 레지스터가 삽입된 이중버스구조라 칭할 수 있겠는데, 이렇게 함으로써 속도를 개선하고 안정성을 유지할 수 있다고 보았기 때문이다. The purpose of this paper is to give Korean students general ideas for designing a new LAN and to stimulate them to be able to develop a new Korean LAN like Cambridge Ring. SNAKE(System Network Architecture for korean Ether) is a suggested PC LAN system. The general purpose computers such as IBM or true IBM compatible PC's. SNAKE is physically bus structured, and logically a slotted ring. It uses two sets of parallel structured coaxial cables to send messages bidirectionally. Each set of cables bears base carrier to a single direction. That is, one cable is dedicated to send frames only to one specified direction. This architecture can be called a register-insertion dual-bus architecture since SNAKE also utilizes the register insertion method to speed up the message propagation and to maintain stability. Each frame passes a station via the registers which is logically inserted into the coaxial cable segments.

ISDN에 접속될 LAN으로서의 PBX System에 관한 고찰

임건우 광주대학교 1990 論文集 Vol.7 No.-

This paper considers the possibility of a PBX system as LAN which will be connected to ISDN trunks. As is well known, the purpose of the PBX systems is to give users of an organization convenience for telecommunications. Today, these convenient features of a PBX are much more enhanced, and the ISDN features promise that users can connect their ocmmunication devices easily to a digital long-haul network. Thus we suggest to reilluminate the PBX system as convenient and economic LANs for Korean users in the near future. PBX or CBX systems could be powerful owing to the following enhanced characteristics : 1) Digital Phones, which enables integrated voice and data transmissions. 2) Distributed Atchitecture, which enables easy error recovery and correction via redundant hardware. 3) Nonblocking Configuration, which makes completely dedicated lines per user. Some desiarable studies and innovations of the PBX components/systems are suggested, such as : 1) Architectural improvement of PBX system via hiring fiber optic links, IPBX, and/or DBDS. 2) Developing efficient protocols for PABX LAN without using modems. Fast packet Switching or Hybrid Switching network is promising. 3) Improvement of switching Archietecture for faster operations. 4) Studies on the Korean language interface to the ISDN network.

The purpose of this study is to find out the opinion of domestic professional baseball fans on whether sports athlete who was a perpetrator of school violence in the past can be selected as a national representative when he is performing well and to be used as basic data for public opinion when similar situations occur in the future. Furthermore, ultimately the study presents the value that should be prioritized between the ethics and performances of sports athlete. To verify this, a survey was conducted on domestic professional baseball fans for 10 days from September 1, 2022, before the selection of the WBC national team, and 238 valid responses were collected. Using SPSS 25.0, AMOS 22.0, and Process Macro (model 4, 8) program, frequency analysis, confirmatory factor analysis, reliability analysis, correlation analysis, and regression analysis were performed. The results are as follows. First, the perceived morality had negative (-) impacts on the perceived critical selection. Second, the perceived critical selection had negative (-) impacts on spectating intention in the future. Third, the perceived morality had positive (+) impacts on spectating intention in the future. Fourth, the perceived critical selection mediated the relationship between the perceived morality and spectating intention in the future. Fifth, the perceived performance did not moderate the relationship between perceived morality and perceived critical selection. Sixth, the perceived performance did not moderate the relationship between perceived critical selection and spectating intention in the future. 본 연구는 첫째, 국가대표로 선발하고자 하는 특정 스포츠 선수가 최근 우수한 성적과 함께 과거 학교폭력 가해 경험이 있는 경우 스포츠 팬은 어떤 반응을 보이는지 파악하고자 하며, 이를 통해 향후 유사한 상황에 여론 확인의 기초 자료로 활용하고자 한다. 둘째, 궁극적으로 스포츠 선수의 윤리성과 실력 사이에 우선시 되어야 할 가치를 명확히 제시하고자 한다. 이를 위해 WBC 국가대표 선발 이전 시점인 2022년 9월 1일부터 10일간 국내 프로야구 팬을 대상으로 설문을 진행하여 유효한 238부의 자료를 수집하였다. 선행연구를 근거로 설정된 가설을 검증하기 위해 SPSS 25.0, AMOS 22.0과 Process Macro 3.5(model 4, 8) 프로그램을 활용하여 빈도분석, 확인적 요인분석, 신뢰도 분석, 상관관계 분석 및 회귀분석을 실시하였다. 그 결과 첫째, 지각된 도덕성은 비판적 선발인식에 부정적 영향을 미치는 것으로 나타났다. 둘째, 비판적 선발인식은 향후 관람의도에 부정적 영향을 미치는 것으로 나타났다. 셋째, 지각된 도덕성은 향후 관람의도에 긍정적 영향을 미치는 것으로 나타났다. 넷째, 지각된 도덕성과 향후 관람의도의 관계에서 비판적 선발인식의 매개효과가 유의한 것으로 나타났다. 다섯째, 지각된 도덕성과 비판적 선발인식의 관계에서 지각된 경기력의 조절효과가 유의하지 않은 것으로 나타났다. 여섯째, 비판적 선발인식과 향후 관람의도의 관계에서 지각된 경기력의 조절효과가 유의하지 않은 것으로 나타났다.

게이트 레벨의 단·결선오류 검출 알고리즘

임건우 광주대학교 1996 産業技術硏究 Vol.7 No.-

본 논문에서는 간단한 부울연산을 통해 게이트 레벨에서의 단순 단·결선 오류(Single Stuck-at Fault)를 검출할 때 fault propagation을 구할 수 있는 알고리즘을 제안하였다. 제안된 알고리즘은 Stuck-at fault를 검출할 수 있는 입력 조합들(fault set)을 형성한다. 형성된 입력조합들을 입력함으로써 완성된 게이트의 stuck-at fault들을 검출해 낼 수 있다. The paper suggests an algorithm devised to easily generate fault propagation for detecting gate-level single stuck-at faults. The algorithm produces an input set for the given detection purposes. Inputting the input set enables detecting the stuck-at faults of the fabricated gates.

임건우,유영동,최경화,이승렬,박동수,홍영권 영남대학교 의과대학 2018 Yeungnam University Journal of Medicine Vol.35 No.2

Background: To evaluate the success rate of balloon dilation and the factors possibly influencing the outcomes of balloon dilation for the ureteric strictured portion of ureteroureterostomy (UUS) site in patients with post-gynecologic surgeries. Methods: A single institution data base was screened for the patients who received balloon dilation for a treatment of ureteral stricture diagnosed after gynecologic surgery. Overall 114 patients underwent primary intra-operative UUS due to ureteral injury during gynecologic surgery. Among them, 102 patients received balloon dilation, and their medical records were retrospectively reviewed. Success of balloon dilation was defined as the condition that requires no further clinical interventions after 6 months from balloon dilation. Results: The ureter injury rate of women treated with open radical abdominal hysterectomy was highest (32 cases, 31.4%). 60 patients (60.8%) showed successful outcomes regarding dilation. All patients underwent technically successful dilation with a full expansion of balloon during the procedure, but 40 patients (39.2%) were clinically unsuccessful as they showed a recurrence of ureteral stricture on the previous balloon dilation site after the first dilation procedure. Univariate logistic regression analyses showed that stricture length >2 cm was a significant predictor of successful dilation (odds ratio, 0.751; 95% confidence interval, 0.634-0.901; p-value, 0.030), but it failed to achieve independent predictor status in multivariate analysis. Conclusion: Balloon dilation can an effective alternative treatment option for strictured portion of the primary UUS in post-gynecologic surgery patients when its length is <2 cm.

In this study, nine commercial enzymes were tested on yuzu powder to reduce the bitterness commonly caused by naringin and neohesperidin. Enzyme-treated yuzu (ETY) was investigated for its dietary fiber composition, physicochemical properties, product stabilities, and functional properties. The Rapidase Fiber enzyme resulted in the highest reduction rates in terms of bitterness compounds at a 5% substrate concentration and 0.1% enzyme concentration and with a 12 h reaction. Compared to those in crude yuzu (CY), ETY exhibited an increase in the total and water-soluble dietary fiber by 3.51% and 5.23%, respectively, whereas insoluble dietary fiber decreased by 1.71%. Enzyme treatment improved product stability with increases in the water- and oil-holding capacity, swelling potential, and solubility. An electronic tongue analysis indicated an 85% reduction in bitterness based on naringin compared to that with CY. Moreover, ETY suppressed lipid accumulation in 3T3-L1 cells, by more than 17% compared to that with CY. In conclusion, ETY effectively reduced bitterness and improved inhibition of lipid accumulation, suggesting that it could be a potential antiobesity ingredient.
