Objectives: The purposes of this study were (1) to determine the reliability of the Korean version of the Scale of Parental Involvement and Self-efficacy-Revised (SPISE-R-K), (2) to examine whether rehabilitation experience and residual hearing level have an impact on parental self-efficacy and their involvement in rehabilitation processes, and (3) to describe the early intervention for young children with hearing loss (CHL) and their caregivers in Korea by analyzing the items in the SPISE-R-K. Methods: We collected 61 SPISE-R-K questionnaires from the caregivers of CHL (mean age= 20.85 months, SD= 7.85; male= 33, female= 28). All children used hearing devices (hearing aid (s) users= 36; cochlear implant (s) users= 25). The reliability of the questionnaire was assessed, and the effects of rehabilitation experience, and children’s residual hearing were examined for the sub-sections of ‘Knowledge’, ‘Confidence’ and ‘Action’. Moreover, the item scores from each section were compared. Results: Cronbach’s α analyses indicated that the SPISE-R-K was reliable in measuring the self-efficacy and involvement of caregivers of CHL. We found that the rehabilitation experience did not show a significant effect on each section’s score whereas residual hearing level had a significant effect on the ‘Knowledge’ section scores. Overall, parents showed higher self-efficacy in items related to auditory access than in items related to language development. Conclusion: The SPISE-R-K is a reliable tool for measuring the self-efficacy and involvement of Korean caregivers of young CHL. We hope that professionals utilize SPISE-R-K to identify the information that needs to be provided to caregivers of young Korean children with hearing loss, making it a valuable tool for early intervention.

PKI 방식의 차세대 이동통신 망에 적용 가능한 인증서 검증 절차 설계

정종민,이구연 江原大學校 産業技術硏究所 2002 産業技術硏究 Vol.22 No.A

When the wireless PKI is applied to 3G/4G mobile network which requires mutual authentication among all entities, the wired PKI procedure is not feasible for validating visited network's certifications because of the wireless environmental limitations. Also, if we depend on WAP based PKI, we cannot support confidence about certification validation since the information offered from visited network is not authenticated. Therefore, in this paper we consider various and unique characteristics of mobile environment for certification validation at 3G/4G mobile networks based on wireless PKI and then propose two certification validation procedures.

3G 이동 통신 환경의 Virtual Home Environment에 적용할 확장된 상호 인증 구조 제안 : 3-party 상호 인증 시나리오 3-party Mutual Authentication Scenario

정종민,이구연 강원대학교 정보통신연구소 2002 정보통신논문지 Vol.6 No.-

The virtual home environment(VHE) which was born for personal service environment portability and global roaming services is an essential concept for 3G mobile network. To support service mobility, when a mobile station(MS) accesses visited network(VN), the subscriber's profile is required by VN. This case may expose user information to untrusted VN. To solve this, it is necessary to authenticate among MS and network to provide communication identification and confidentiality. Because VHE researches have been focused on service logic and service data repositories, it is necessary to go side by side with user profile protection In this paper, we proposed a 3-party mutual authentication scheme for VHE in 3G mobile network, which simultaneously goes with existing authentication mechanisms and VHE scenarios.

ISDN AO/DI 시스템에서 버퍼링 기능 구현으로 인한 성능 향상

정종민,이구연 강원대학교 산업기술연구소 2000 産業技術硏究 Vol.20 No.B

ISDN AO/DI provides efficient communication. It dynamically allocates channels for bandwidth, which is key component for packet data communication. In this paper, we analyze performance improvement of ISDN AO/DI system with buffering scheme and compare with AO/DI system without buffering scheme. From the simulation of AO/DI with buffering scheme, we see that the required bandwidth is less than of the AO/DI system without buffering scheme.

아밀로스함량 차이에 따른 벼 배유전분의 이화학적 특성평가

정종민,정지웅,이상복,김명기,김보경,김보경,손재근 韓國作物學會 2013 한국작물학회지 Vol.58 No.3

아밀로스 함량차이에 따른 배유전분의 이화학적 특성을 파악하기 위해 아밀로스 함량의 차이를 보이는 찰벼, 저 아밀로스, 중간 아밀로스, 고 아밀로스 품종의 외관특성, 화학특성, 호화특성 및 기계적 식미치를 조사하였으며, 그 결과를 요약하면 다음과 같다.1. 시료들의 아밀로스 함량은 6.3%∼30.9% 범위로 아밀로스 함량차이에 따라 4개 그룹 찰벼(A), 저 아밀로스(B), 중간 아밀로스(C), 고 아밀로스(D) 품종군으로 나눌 수 있었으며 각 그룹에 속한 품종들의 단백질함량은 5.8 ~ 7.5%로 품종간 차이가 있었으나 아밀로스 함량에 따라 분류된 그룹간 차이는 없었다.2. 시험재료의 외형적 특성을 보면, 백도는 찰벼 품종군이 가장 높고 저아밀 중간아밀로스 품종군이 가장 낮았다. 현미경도는 고 아밀로스 품종 및 찰벼 품종이 메벼품종과 저 아밀로스 품종보다 대체적으로 낮았다.알카리 붕괴도는 5.2∼6.9의 분포를 보였으며 아밀로스 함량이 증가할수록 붕괴도가 커졌으며, 아밀로스 함량과 알카리 붕괴도 간 매우 높은 양의 상관(r=0.884**)을 보였다.3. 아밀로그램 특성을 살펴보면 저 아밀로스 품종군은 호화개시온도가 중간 아밀로스 품종과 비슷한 반면 최고점도와 강화점도는 높고 최종점도와 치반점도는 낮았다. 고 아밀로스 품종군은 호화개시온도가 다른 품종군에 비해 높고, 최고점도와 최저점도가 매우 낮았으며 최종점도가 상대적으로 높아서 강하점도는 낮고 치반점도는 높은 특성을 보였다.4. 식미관련 이화학적 특성들 간 상관을 살펴보면 아밀로스함량은 알카리 붕괴도와 상당히 높은 양의 상관(r=0.88**)을 Toyo-윤기치와는 높은 음의 상관(r=-0.89**) 나타냈고, 아밀로그램 특성 중에서는 호화개시온도, 치반점도와 유의한 양의 상관을 보이며, 강하점도와는 음의 상관을 나타냈다. This study was carried out to find out the physicochemical properties of rice grains of 8 varieties having various amylose content. Amylose contents of 8 varieties were ranged from 6.3 to 30.9% and could be classified into 4 groups, such as waxy, low-amylose, nonglutinous, and high-amylose. Protein contents were ranged from 5.8% to 7.5% varied depending on variety, but there was no significant difference in protein contents among groups. The hardness of milled rice grains in low-amylose and non-glutinous was stronger than waxy and low-amylose group. Whiteness of waxy group grains was the highest while non-glutinous group was the lowest. The alkaline digestive values were evenly distributed from 5.2 to 6.9 and highly correlated with amylose content. There was significant difference in pasting properties of rice flours among groups. High-amylose group showed the highest initial pasting temperature and total setback viscosity, and the lowest peaks for trough and breakdown viscosity. Low-amylose group showed the highest breakdown viscosity but the lowest setback viscosity as well as high peak viscosity. Although amylose content was significantly correlated with alkali spreading value in milled rice, initial pasting temperature, and total setback, but it was negatively correlated with toyo-meter value and setback viscosity.

벼 형질전환계통의 미질특성에 대한 고찰

정종민,정지웅,강경호,이상복,모영준,김정곤,김경민,손재근 韓國作物學會 2013 한국작물학회지 Vol.58 No.2

국내 대학과 국립식량과학원 간의 협력 연구를 통해 확보된 32개 벼 형질전환 계통들 중 작물학적 성능이 유망한 11개 계통들에 대해 작물학적 특성과 미질 특성이 평가되었다. 주요 결과는 아래와 같다.1. 이들 계통들은 수량성, 환경스트레스저항성, 내병성에관여하는 7종의 유전자가 니폰바레, 낙동벼, 동진벼등에 형질전환 되어 육성된 계통들이다.2. 미질 특성과 관련된 11개 조사형질을 이용한 다변량분석결과, 형질전환에 이용된 모품종과 도입유전자들에 대한 각 형질전환 계통군들의 뚜렷한 집구현상은관찰되지 않았다.3. 실용적 측면에서는 작물학적 특성이 모품종과 유사하면서 미질 특성이 양호한 계통이 다수 확인되었다.4. 그러나 모품종의 유용한 작물학적 특성, 즉 ‘상품성’을온전히 견지하고 있다고 판단되는 계통은 선정하기 어려웠다.5. 도입할 유전자의 선정과 유전적으로 고정된 형질전환계통을 확보하는데 소요되는 경비와 시간을 고려할때, 향후 우량 벼 형질전환 계통의 육성효율을 제고하기 위해서는 기존에 비해 보다 구체적이며 차별화 된육종전략의 개발이 필요하다고 판단되었다. Selected 11 rice transgenic lines, through preliminary yield trials on 32 lines, were evaluated on important agronomic traits as well as grain quality by conducting replicated yield trials having three replication plots. Japonica recipients, Nipponbare, Nagdongbyeo, and Dongjinbyeo, were the recipients of 7 transformed genes, which were putatively related with high yield, abiotic stress tolerance, and disease resistance. To estimate the degrees of deviations from the wild types, 11 traits of transgenic lines, relating with grain quality were evaluated and subjected to multivariate analyses. Principal coordinate and clustering analyses did not support collection manners of transgenic lines in terms of the genes transformed as well as the genetic background. Meanwhile, some transgenic lines would be acceptable due to their over-all performances were similar to their wild types, it was hardly possible to declare any transgenic line, which adhered closely to the commercial profits of wild type. Thereby, with considerations on the demanding resources in establishing rice transgenic lines having market competitiveness, it was speculated that proper application of breeding strategies would be crucial factor for the efficiency of developing prospective rice transgenic lines.
