유비쿼터스도시의 건설 등에 관한 법률은 2010년까지 신도시 지역에 활발히 추진된 U-City 사업의 제도적 근간으로 작용하여 왔다. 그러나 최근 기성시가지 재활성화, 도시재생 중심으로 국가의 도시정책이 변화됨에 따라 신도시 중심의 절차법적 성격이 강한 U-City법 개정에 관한 요구가 증대되고 있다. 이에 본 연구에서는 국가 도시정책의 변화와 U-City를 둘러싼 여건변화를 감안하여 U-City법 개정방향을 U-City 사업다양화, U-City 관리운영 강화, U-City 사업지원으로 설정하고 그에 따른 세부 추진방안을 제시하였다. 본 연구는 국가 도시정책 흐름 및 수요를 반영함에 있어 실무적 관점에서 현행 U-City법이 가지는 문제점을 살피고 그 개선방안을 제시하는데 그 목적이 있다. 본 연구의 결과는 지속적인 U-City 발전 및 확산을 법제도적으로 지원하기 위한 기초자료로 활용될 수 있을 것으로 기대된다.

본 연구(硏究)는 Johansen 공적분(共積分) 분석(分析) (cointegration analysis)을 이용하여 캐나다 (Canada) 내(內)의 5개 지역(地域) (Atlantic, Quebec, Ontario, Prairie, British Columbia) 침엽수(針葉樹) 제재(製材) (softwood lumber) 가격(價格)의 일가(一價)의 원칙(原則) (law of one price)이 성립하는지 구명(究明)하는데 그 목적(目的)이 있다. 1987년 10월부터 1998년 11월까지의 월간(月刊) 시계열자료를 이용하였으며 단위근(單位根) 검증법(檢證法) 중 가장 많이 사용되는 Augmented Dickey-Fuller (ADF) 검증법을 이용한 결과 연구에 이용된 모든 수준변수 (level variables)들은 불안정적(不安定的) (non-stationary)이지만 차분변수 (differenced variable)들은 안정적이므로 공적분 분석의 선결조건(先決條件)이 만족되었다. Johansen 공적분 분석결과 캐나다 (Canada) 내(內)의 5개 지역(地域) 침엽수(針葉樹) 제재가격(製材價格)의 일가(一價)의 원칙(原則) (law of one price)이 성립되는 것으로 나타났다.

이 연구는 우리나라 경비업 현황분석을 통하여 현재 경비업의 개괄적 실태를 살펴본 후, 경비업법 개정과정 분석을 통하여 어떠한 정책기조가 법 개정에 투영되었는가를 도출한 다음, 우리나라 시큐리티산업의 정책방향을 제안하는데 연구의 목적을 두고 있다. 경비업법 개정 과정을 통하여 보면 공공성 강화와 기업성 강화가 어떤 뚜렷한 정책적 기조를 이루고 있는 것으로 보이진 않는다. 다만 강력한 공공성의 기조하에 부분적으로 기업성을 일부 반영한 것으로 밖에 해석되지 않는 것이다. 경비업의 건전한 발전을 위해서는 기존의 정책 방향에서 탈피하여 경비업의 기업성을 강화하는 방향으로 정책 기조가 변화되어야 한다. 경찰의 지도 감독 권한을 한국경비협회에 대폭 이관하여 경비업계의 자율적인 정화 기능을 키워야 한다. 경찰에서는 치안서비스의 공동생산 차원에서의 정책 개발에 관심을 두고 지혜를 모아야 할 것이다.

The effect of structure size on the nominal strength of unidirectional fiber-polymer composites, failing by propagation of a kink band with fiber microbuckling, is analyzed experimentally and theoretically. Tests of novel geometrically similar carbon-PEEK specimens, with notches slanted so as to lead to a pure kink band (without shear or splitting cracks), are conducted. The specimens are rectangular strips of widths 15.875, 31.75. and 63.5 mm (0.625, 1.25 and 2.5 in and gage lengths 39.7, 79.375 and 158.75 mm (1.563, 3.125 and 6.25 in.). They reveal the existence of a strong (deterministic. non-statistical) size effect. The doubly logarithmic plot of the nominal strength (load divided by size and thickness) versus the characteristic size agrees with the approximate size effect law proposed for quasibrittle failures in 1983 by Bazant This law represents a gradual transition from a horizontal asymptote, representing the case of no size effect (characteristic of plasticity or strength criteria), to an asymptote of slope -1/2 (characteristic of linear elastic fracture mechanics. LEFM) . The size effect law for notched specimens permits easy identification of the fracture energy of the kink bandand the length of the fracture process zone at the front of the band solely from the measurements of maximum loads. Optimum fits of the test results by the size effect law are obtained, and the size effect law parameters are then used to identify the material fracture characteristics, Particularly the fracture energy and the effective length of the fracture process zone. The results suggest that composite size effect must be considered in strengthening existing concrete structural members such as bridge columns and beams using a composite retrofitting technique.

Let {$X,\;X_n;n{\geq}1$} be a sequence of i.i.d. random variables. Set $S_n=X_1+X_2+{\cdots}+X_n,\;M_n=\max_{k{\leq}n}|S_k|,\;n{\geq}1$. Then we obtain that for any -1$\lim\limits_{{\varepsilon}{\searrow}0}\;{\varepsilon}^{2b+2}\sum\limits_{n=1}^\infty\;{\frac {(log\;n)^b}{n^{3/2}}\;E\{M_n-{\varepsilon}{\sigma}\sqrt{n\;log\;n\}+=\frac{2\sigma}{(b+1)(2b+3)}\;E|N|^{2b+3}\sum\limits_{k=0}^\infty\;{\frac{(-1)^k}{(2k+1)^{2b+3}$ if and only if EX=0 and $EX^2={\sigma}^2<{\infty}$.

The purpose of this study was to identify what factors are associated with marital satisfaction of the foreign wives who live in small town. Data for the study were based on a snowball sampling of 101 foreign wives who married to Korean husbands and had residence in Changwon and Masan city, Gyeongnam, Korea. The respondents reported higher levels of marital satisfaction and lower levels of marital hardship. To identify the variables affecting marital satisfaction, a regression analysis was conducted. Independent variables included age difference, educational difference, monthly income, conformity of information about husband, marital hardship, relationship with parents-in-law and taking class with husband. While conformity of information about husband, marital hardship and taking class with husband had strong effects on marital satisfaction of the foreign wives, age difference, educational difference, monthly income and relationship with parents-in-law didn't show the significant effects on the marital satisfaction of the foreign wives.

The construction industry has maintained a strong level of development in China in recent years. And with the steady development of the national economy, the construction industry will continue its momentum of growth in the coming years, which indicates a great tendering market in China. To gain a comprehensive understanding of Chinese tender market, a research based on construction laws and tendering laws was carried out. This research focused on differences of the tender environment between China and Korea, such as construction company certificate, bidding procedure and so on.

In [5], Csorgo and Zitikis exposed the strong $uniform-over-[0,\;{\infty}]$ consistency, and weak $uniform-over-[0,\;{\infty}]$ approximation of the empirical mean residual life process by employing weight functions. We carry on the uniform asymptotic behaviors of the empirical mean residual life process over the whole positive half line by representing the process as an integral form. We compare our results with those of Yang [15], Hall and Wellner [8], and Csorgo and Zitikis [5].

In recent years, there's been strong demand for seawalls that havea gentle slope and permeability that serveswater affinity and disaster prevention from wave attack. The aim of this study is to examine wave transformation, including wave run-up that propagates on the coastal structures. A numerical model based on the weak nonlinear dispersive Boussinesq equation, together with the unsteady nonlinear Darcy law for fluid motion in permeable layer, is developed. The applicability of this numerical model is examined through Deguchi and Moriwaki's hydraulic model test on the permeable slopes. From this study, it is found that the proposed numerical model can predict wave transformation and run-up on the gentle slope with a permeable layer, but can't show accurate results for slopes steeper than about 1:10.

I discuss implications of gamma-ray emission from blazars based on electron acceleration by shock waves in a relativistic jet. The number spectrum of electrons turns out to be a broken power law; while at low energies the power law index has a universal value of 2, at high energies it steepens to an index of 3 because of strong radiative cooling. This spectrum can basically reproduce the observed spectral break between X-rays and gamma-rays. I show that energetics of relativistic jets can be well explained by this model. I estimate physical quantities of the relativistic jets by comparing the prediction with observations. The results show that the jets are particle dominated and are comprised of electron-positron pairs. A connection between gamma-ray emission and radiation drag is also discussed.
