University enrollment has long been regarded as one of the major factors inducing population concentration in Seoul and the Capital Region of Korea. Consequently, since early 1980's increases in enrollment and new establishments of extention universities beyond the boundary of Seoul, has been promoted, while university enrollment quota in Seoul has been strictly controlled. The degree of actual population dispersal, however, resulting from such a university enrollment policy has not been empirically tested. This paper aims at: First, identifying the trend of population growth and evolution process of the university enrollment policy in the Capital Region; Second, comparing the degree of influence of university enrollment on population concetration factors; Third, measuring actual effect of the enrollment control on population dispersal out of Seoul and the Capital Region. Major findings are as follows: First, only a week correlation between population and university enrollment growth trends was found; Second, the relative degree of influence on population concentration in the Capital Region, were order, in the order of magnitude, the physical amenity factor, the socio-cultural amenity factor, the employment climate factor and the educational factor. Third, and most improtant, based on the comparison of spatial distribution of graduated high schools and current residence of the selected university students, the gap between the two distributions was revealed and the inter-regional student population movement was estimated. The result shows that in Seoul's case about one-half of and in Kyunggi Province's case about one-fifth of university enrollment size, contributes to population concentration into Seoul. Fourth, as to the universities outside of the Capital Region, little effect in the case of universities located within the commuting distance, and a little effect on population dispersal in the case of universities located beyond commuting distance, were found. In sum, it seems clear that university enrollment policy in the Capital Region, especially in Inchon/Kyunggi Province has not been effective on student population dispersal out of Seoul and the Capital Region. Therefore, it is strongly recommended that university enrollment policy be throughly re-examined from its goal to the implementation means.

- Abstract - Objectives: The purpose of this paper is to determine an efficient operation plan for a smoking cessation clinic in public health centers. To do so, the primary success factors in smoking cessation have been analyzed after classifying the smoking cessation programs of public health centers into urban and rural areas. Methods: A study was conducted with 262,837 smokers age 19 or older who were provided with smoking cessation services for more than 6 months through smoking cessation clinics at public health centers(250 clinics nationwide) from July 16, 2006 to July 15, 2007. Results: Urban areas indicated that gender, age, social security, the frequency of counseling, re-enrollment in the program, the number of cigarettes per day and alcohol problems were all factors that influenced the success of smoking cessation. On the other hand, in the rural areas the total number of counseling, re-enrollment in the program, the number of cigarettes per day and alcohol problems were the influential factors. Furthermore, the urban area confirmed that the frequency of counseling, re-enrollment in the program, the number of cigarettes per day and alcohol problems affected traveling while the rural area was affected by social security, the frequency of counseling and re-enrollment. Conclusions: It has been confirmed that the success rate and factors of smoking cessation clinics can vary depending on the region and enrollment method.

PURPOSE. The purpose of this study was to evaluate the effectiveness of a promotion campaign for subject recruitment and selection, and reasons of withdrawal from a prospective clinical trial of mandibular two-implant supported overdenture. MATERIALS AND METHODS. The subjects of this study were participants in a randomized controlled clinical trial for investigating prognosis of implants and overdentures with attachments. Recruited subjects were classified by gender, age, and participation motives. Withdrawal rate of the participants before and after enrollment were evaluated. RESULTS. 177 patients were recruited and 51 patients were enrolled for the trial. Among them, 40 participants eventually took part in the trial. 116 subjects (65.5%) were recruited by advertisement and 61 (34.5%) were referred by patients of the hospital or local clinics. Regarding recruitment effectiveness, newspaper recruited the largest number of participants. With respect to referral patients, the proportion of our hospital patients was higher (37/61). Subjects in their 70s comprised the largest proportion (22/51). The male to female ratio was similar (25:26). Final withdrawal rate of all subjects were 74.0%. Among the reasons for withdrawal from enrollment (n=126) presence of remaining teeth and lack of motivation were the most common reasons. CONCLUSION. To facilitate recruitment of clinical trial subjects and improve enrollment rate, it is important to obtain a sufficient number of researchers, perform promotion activity with diverse strategies, cooperate with local dentists, increase the research funding, and alleviate subjects' fear against clinical trials by thorough consultation.

The purpose of this study was to analyze the number of university entrants influenced by the population decline of school age, to discuss the major issues of university restructuring policy initiated by government, and to suggest the mid- to long-term policy agenda on university restructuring. According to the analysis of university enrollment changes, university enrollment quota will decrease to 29% of year 2013. And the ratio of private university enrollment and the entrants of universities in the metropolitan areas will increase. Under these circumstances, it is highly concerned that high school graduates will be more concentrated to private universities located in the metropolitan areas. The government policy on university restructuring have several problems on the direction, the pursuing strategies, and the negative impacts of it. This study suggested the new paradigm for the university development and also the alternative strategies such as the balanced development in universities, financial support system, school-to-work policy, university collaboration system, and an enactment of university development.

One key factor that hinders the widespread deployment of speaker identification technologies is the requirement of long enrollment utterances to guarantee low error rate during identification. To gain user acceptance of speaker identification technologies, adaptation algorithms that can enroll speakers with short utterances are highly essential. To this end, this paper applies MLLR speaker adaptation for speaker enrollment and compares its performance against other speaker modeling techniques: GMMs and HMM. Also, to speed up the computational procedure of identification, we apply speaker clustering method which uses principal component analysis (PCA) and weighted Euclidean distance as distance measurement. Experimental results show that MLLR adapted modeling method is most effective for short enrollment utterances and that the GMMs performs better when long utterances are available.

Background: Humidifier disinfectant is a biocidal product used in the water tanks of humidifiers to prevent the growth of microorganisms. Although there are a huge number of cases of reported humidifier disinfectant-related health effects across the entire Korean population, their numbers are distributed differently depending on the region. Objectives: This study aimed to investigate the regional distribution of enrollment cases who reported humidifier disinfectant-related health effects. Methods: This study used data on 6,240 subjects who experienced humidifier disinfectant-related health effects and who enrolled their cases which is conducted by the Korea Ministry of Environment. We examined the regional distribution of the enrolled cases based on sixteen administrative divisions and assessed the: 1) crude number; 2) proportional rate; and 3) age-standardized proportional rate of enrollment by region. Results: When we examined the crude number of enrollments by region, the highest number were in Gyeonggi-do Province (n=1,896), followed in order by Seoul (n=1,405), Incheon (n=436) Busan, Daegu, Gyeongsangnam-do Province, Daejeon, Chungcheongnam-do Province, Gyeongsangbuk-do Province, Jeollabuk-do Province, Gwangju, Chungcheongbuk-do Province, Gangwon-do Province, Jeollanam-do Province, Ulsan, and Jeju-do. When we examined proportional rate of the regional enrollment (cases per 100,000 population), Daejeon (n=16.2) was the region with the highest rate, followed in order by Gyeonggi-do Province (n=16.1), Incheon-do Province (n=15.9), Seoul, Daegu, Gwangju, Jeollabuk-do Province, Chungcheongnam-do Province, Busan, Chungcheongbuk-do Province, Gangwon-do Province, Gyeongsanbuk-do Province, Gyeongsangnam-do Province, Ulsan, Jeju-do, and Jeollanam-do Province, which is inconsistent with the order in terms of crude numbers. However, when we examined the age-standardized proportional rate of regional enrollment (cases per 100,000 population), their ranked distribution is consistent with the crude rate. Conclusions: This study observed that the regional distribution of the enrolled cases who reported humidifier disinfectant-related health effects is inconsistent with the regional distribution of the proportional rate of enrollment cases, which may be caused in part by the volume of the inherent population of each region.

본 논문은 등록 지문의 정보를 융합하여 보다 많은 정보를 이용함으로써 지문 검증의 성능을 향상시키는 방법을 제안한다. 크기가 작은 센서는 많은 응용 분야에 적용시킬 수 있는 장점을 가지지만, 실제 지문을 입력 받는 센서 입력창의 물리적인 크기가 작기 때문에 지문 정보를 충분히 입력받지 못할 뿐만 아니라 등록된 지문 영상과 검증을 위해 입력된 지문 영상 사이의 공통영역이 축소되어 전체적인 시스템의 성능을 저하시키는 문제점이 있다. 이러한 문제점은 등록 영상을 여러 장 받아 그 정보를 융합하여 보다 큰 지문 영역을 표현하도록 함으로써 해결할 수 있다. 이를 위해서는 등록 영상간의 좌표계를 정밀하게 일치시키는 과정이 무엇보다 중요하다. 본 논문에서는 먼저 등록영상 사이의 대응 특징점 쌍을 이용하여 거칠게 일치시킨 다음, 융선의 정보를 포함하는 Distance Map을 이용하여 정밀하게 일치시키는 방법을 사용하였다. 정밀하게 일치된 좌표계를 통해 각각의 등록 지문들의 특징 정보는 하나의 큰 등록 정보로 형성된다. 제안된 방법을 통해 형성된 특징 융합 정보는 보다 넓은 면적의 지문을 표현할 수 있기 때문에 센서 입력창이 작아서 생기는 문제를 극복함으로써 지문 인식기의 성능을 향상시킨다. 본 논문의 실험 견과는 제안한 융합 특징 정보를 이용하는 방법이 그렇지 않은 방법보다 지문 인식기의 성능을 월등하게 향상시킴을 보여준다.

Purpose: The present study assessed the role of an amino acid-based formula (AAF) in the growth of infants with cow's milk protein allergy (CMPA). Methods: Non-breastfed, term infants aged 0-6 months with symptoms suggestive of CMPA were recruited from 10 pediatric centers in China. After enrollment, infants were started on AAF for two weeks, followed by an open food challenge (OFC) with cow's milk-based formula (CMF). Infants with confirmed CMPA remained on AAF until 9 months of age, in conjunction with a cow's milk protein-free complementary diet. Body weight, length, and head circumference were measured at enrollment and 9 months of age. Measurements were converted to weight-for-age, length-for-age, and head circumference-for-age Z scores (WAZ, LAZ, HCAZ), based on the World Health Organization growth reference. Results: Of 254 infants (median age 16.1 weeks, 50.9% male), 218 (85.8%) were diagnosed with non-IgE-mediated CMPA, 33 (13.0%) tolerated CMF, and 3 (1.2%) did not complete the OFC. The mean WAZ decreased from 0.119 to -0.029 between birth and enrollment (p=0.067), with significant catch-up growth to 0.178 at 9 months of age (p=0.012) while being fed the AAF. There were no significant changes in LAZ (0.400 vs. 0.552; p=0.214) or HCAZ (-0.356 vs. -0.284; p=0.705) from the time of enrollment to age 9 months, suggesting normal linear and head growth velocity. Conclusion: The amino acid-based study formula, in conjunction with a cow's milk proteinfree complementary diet, supported normal growth till 9 months of age in a cohort of Chinese infants with challenge-confirmed non-IgE-mediated CMPA.
