지방재정 확보에 관한 연구

임재현 숙명여자대학교 사회 교육과학연구소 2001 사회 교육과학연구 Vol.4 No.2

일반적으로 지방자치단체를 둘러싼 현재의 환경변화는 지방재정수요를 증대시킴으로써 지방자치단체의 재정적 어려움을 야기시킨다고 인식되고 있다. 우리날 지방자치단체의 재정수입도 최근에 급증하고 있는 재정수요를 충족시키지 못하고 있다. 이러한 인식하에서 본 연구는 우리나라 지방재정수입의 현황을 살펴보고, 이를 토대로 문제점과 개선방안을 논의한다. 우리나라 지방재정수입의 문제점으로는 지방세의 비중이 낮으며, 지방세수입이 재정과세중심적이고, 지방자자치단체의 재정자립수준이 낮아서 자주재원이 해당 자치단체에 근무하는 공무원들의 인건비를 충당하지 못하는 경우가 다수 존재하며, 경영수입사업과 지방채발발행이 효과적으로 수행되지 못하는 점 등이 지적될 수 있다. 따라서, 지방재정을 확충하기 위해서는 다음과 같은 방안들이 시행되어야 한다. 첫째, 국세중 일부를 지방세로 전환한다. 둘째, 세외수입을 증대시키기 위해 경영수입사업을 효과적으로 운영해야 하며, 이를 위한 수단으로 전담조직을 구축하고 민영화와 업무평가를 시행한다. 셋째, 지방자치단체간의 재정력 격차를 완화시키기 우해 지방재정조정제도를 활성화하되, 지방교부세와 지방양여금 중심적으로 운영되어야 한다. 넷째, 지방자치시대에 맞게 탄력적으로 운영해야 한다. The recent change in function and role of local governments has increased the local finance demands, thereby causing the fiscal stresses of most municipalities. This is true ok Korean local governments. In this respect, the study is focused on reviewing the present financial conditions of Korean local governments, on analyzing their problems, and on suggesting the policy alternatives. In Korea, there are many problems in local finance as mentioned below: (1) the portion of local tax revenue vs national tex revenue is low; and (2) local tax revenue is property-tax-oriented; (3) local finance capacities are in low; and (4) local businesslike enterprises and municipal bonds are managed ineffectively. Therefore, the policy alternatives to improve local fiscal capacities are: (1) to enlarge the local tax bases; (2) to effectively manage the businesslike enterprises of local government; (3) to activate the grants system to reduce horizon and vertical finance inequality among local governments; and (4) to set up theeffective institutional mechanism and operation system of municipal bonds.

중학생의 자살생각에 미치는 영향 - 우울과 위축의 매개효과

임재현,전동일 한국콘텐츠학회 2019 한국콘텐츠학회논문지 Vol.19 No.10

This study analyzed the effects of school violence, parental violence, and academic stress on the middle school students suicidal ideation through depression and withdrawn. For this study, we used data from the 13th wave the Korea Welfare Panel Study(KOWEPS). The analysis was conducted on 391 middle school students. Structural equation modeling by using AMOS was used for this study. As results of the study, the biggest effect on the suicidal ideation was the total effect of school violence, and the direct effect was also significant. In other words, school violence is a partial mediating effect through depression and withdrawn on suicidal ideation. Parental violence was more indirect effect than direct effect through depression on suicidal ideation. In other words, parental violence is a complete mediating effect through depression on suicidal ideation. Academic stress was more indirect effect than direct effect through depression and withdrawn on suicidal ideation. In other words, academic stress is a complete mediating effect through depression on suicidal ideation. Withdrawn was not direct affect, but had an indirect effect through depression on suicidal ideation. Therefore, in order to prevent suicide of middle school students, there is a need for prevention of school violence, parental violence and academic stress, which are causes of depression. 본 연구는 중학생의 자살생각에 학교 및 부모폭력, 학업스트레스가 우울과 위축을 매개로 하여 어떠한 영향을 미치는지를 분석하였다. 이를 위해서 한국복지패널 제13차년도 아동부가조사 자료를 사용하였고, 조사 응답 중학생은 391명이었다. 구조방정식 모형을 통해서 분석한 결과, 자살생각에 효과가 가장 큰 것은 학교폭력의 총효과였으며, 직접적인 효과도 크게 나타났다. 즉, 학교폭력은 자살생각에 우울과 위축을 통한 부분매개효과라고 할 수 있다. 부모폭력은 자살생각에 직접적인 영향보다는 우울을 통한 간접적인 영향이 큰 것으로 나타났다. 즉, 부모폭력은 자살생각에 우울을 통한 완전매개효과라고 할 수 있다. 학업스트레스는 자살생각에 직접적인 영향보다는 우울과 위축을 통한 간접적인 영향이 큰 것으로 나타났다. 즉, 학업스트레스는 자살생각에 우울을 통한 완전매개효과라고 할 수 있다. 위축은 자살생각에 직접적으로 영향을 미치지 않았으나, 자살생각에 우울을 통한 간접효과가 큰 것으로 나타났다. 따라서 중학생의 자살예방을 위해서 우울의 감소와 우울을 발생시키는 원인인 학교폭력 예방과, 부모폭력, 학업스트레스를 줄이기 위한 방안이 필요하다.

In this paper we propose a unified context-aware application model which is an essential part to develop various applications in ubiquitous computing environment. The proposed model affirms the independence between sensor and application by using unified context in the form of external context and internal context. It also ensures that application exploits relatively accurate context to trigger personalized services. To show usefulness of the proposed model, we apply it to the sensors and applications the ubi-class, a testbed for ubi-class system applications.

임재현,하은주,이종수,이승재,박효일 대한신경외과학회 1992 Journal of Korean neurosurgical society Vol.21 No.12

Neurofibromatosis(NF) is the most common autosomal dominant hereditary disease among the phakomatoses. Neurofibromatosis is manifestied by characteristic skin lesion and it is frequently associated with neoplasm of nervous system. Recently, NF is classified NF-1 (previously called Von Recklinghausen NF or peripheral NF) and NF-2(previously called bilateral acoustic NF or central NF). Neurofibromatosis type 1(NF-1) can be combined with many different type of neoplastic disease, such as neurofibrosarcoma, spinal neurofibroma, meningioma optic glioma. arachnoid cyst, etc. Among these, arachnoid cyst is very rarely combined with neurofibromatosis type 1. We experienced a very rare case of the arachnoid cyst which was combined with NF-1.

This paper proposes a new access method which is to considered the high variability in World Wide Web and manage the web cache space. Instead of using a single cache, we divide a cache and store all documents according to their file types. Proposed method was compares with current cache management policies using LFU, LRU and SIZE base algorithm. Using two different workload, we show the improvement hitting ratio and byte hitting ratio through simulation on the file type caching.

임재현,김은정,김학선 한밭대학교 정보통신전문대학원 2004 정보통신전문대학원 논문집 Vol.2 No.1

본 논문에서는 UWB (Ultra-WidrBand)시스템에 사용되는 초광대역 통과 필터를 설계하였다. 고역 통과 필터와 저역 통과 필터를 직렬 연결하여 구현하였다. 10.6 GHz의 cut off주파수를 갖는 저역 통과 필터는 단락된 전송선로와 개방된 전송선로를 이용 하여 구현하였고, 3.1 GHz의 cut of주파수를 갖는 고역 통과 필터는 L과 C의 lumped소자를 이용하였다. 시뮬레이션 결과 통과 대역에서는 S11 값이 18 dB의 값을 얻었으며 두개의 cut off 주파수에서는 S21의 값이 10 dB 감쇄한 결과를 얻었다. In this paper, it was designed ultra-wide band pass filter for UWB(Ultra-Wide Band) system. There was inplemented series connection of high pass filter and low pass filter. Low pass filter accessed cut off frequency of 10.6GHz was designed using short-circuited stubs and open-circuited stubs. High pass filter assessed cut off frequency of 3.1GHz was designed using lumped elements of L and C. Simulation results were obtained 18 dB of S11 from pass band and attenuated 10dB of S21 from two cut off frequencies.

Responsiveness of Gait Speed to Physical Exercise Interventions in At-risk Older Adults: A Systematic Review and Meta-Analysis

임재현,임재영 대한노인병학회 2017 Annals of geriatric medicine and research Vol.21 No.1

Background: In at-risk older adults, gait speed is an important factor associated with quality of life and falling risk. In this study, we assessed whether therapeutic exercise could improve gait speed. Methods: We conducted a meta-analysis to evaluate the ‘best’ therapeutic exercise method by analyzing each exercise in terms of intensity, type, and several gait speed indices. For the analysis, we gathered 122 papers through a database search and selected 9 (n=627) that were appropriate for the meta-analysis. Results: In 8 of the 9 included papers, gait speed improved with therapeutic exercise. Usual gait speed (n=246) improved more than maximal gait speed (n=574). A resistance program was more effective than a nonresistance program for improving maximal, but not usual, gait speed. We also found that the effects of therapeutic exercise were greater in noncommunity than in community-dwelling elderly people. Conclusion: In conclusion, therapeutic exercise was effective in improving gait speed.

임재현,하은주,이종수,이승재,박효일 대한신경외과학회 1993 Journal of Korean neurosurgical society Vol.22 No.2

Tumorous lesion of intra- and suprasellar area showed unique clinical pictures and also was very hazardous and difficult to remove surgically because of the surrounding important anatomical structures. Here, authors analyzed 28 confirmed tumor of this area during last two and half years retrospctively. Histopathologically, 28 cases were classified in 14 pituitary adenoma cased6 cases of non-functioning adenoma, 1 GH-secreting adenoma and 7 cases of prolactinoma), 7 craniopharyngioma cases, 3 meninigioma cases and each one case of germinoma, Rathke's cleft cyst, pituitary abscess and hamartoma. Sexual incidence was 6 : 22 in male vs female ratio. Twenty two cases were measured its diameter over 2cm and they extended to suprasellar area in all cases. Five cases of microadenoma were analyzed and they were all enclosed in sella turcica. Visual impairment was the most frequent and prominent clinical symptom. of which incidence was 78.57% (22 cases). The next frequent symptoms were headache and generalized lethargy. Diabetes insipidus was a presenting symptom in 4 cases and hydrocephalus was noted in 4 cases preoperatively. Surgical intervention was carried out in 23 cases, by the way, the performed type of surgery in 21 cases was a conventional transcranial frontotemporal(pterional) microsurgical method. Post-operatively, diabetes insipidus was complicated in 78.26 % and pituitary hypofunction was noted 34.78%. Two cases of intracranial hemorrhage was developed after surgery and one was died. Through 6 to 28 months follow up. 82.1 % of cases were improved in its clinical status including 7 cured cases.
