국회와 지방자치단체 상호간 입법권한 배분에 관한 헌법적 검토
김해원(Kim, HaeWon) 한국지방자치법학회 2016 지방자치법연구(地方自治法硏究) Vol.16 No.2
The legislative power shall be vested in the National Assembly (Art. 40 of the Constitution). And Local governments shall deal with administrative matters pertaining to the welfare of local residents, manage properties, and may enact provisions relating to local autonomy, within the limit of Acts and subordinate statutes (Art. 117 of the Constitution). Therefore, both the National Assembly and local governments have the legislative power. This Study describes the constitutional standards of legislative power distrìbution between the National Assembly and local governments. 1. Local council is the institution that represents legislative power in Local government. 2. Local Autonomy can be placed under the Principle of Law Reservation. However this law should not govem essential aspect of the Local Autonomy. 3. Principle of Local council Reservation is the outermost barrier of the legislative power of the National Assembly. 4. Principle of subsidiarity functions as first line of defense in relation to the distribution of legislative power between the Nation Assembly and Local governments. 5. Conflict of legislative powers between the National Assembly and Local gevernments is a에 usted in accordance with Principle of supremacy of law. 6. Tt is doubtful whether the Art. 22 of Local Autonomy Act ist a violation of the Constitution .

A proposed testing method of lubricating oil and lubrication characteristics and lubrication quality for gasoline engine, when the engine oil is used for longtime of period. The result shows that the characteristics of engine oil were changed at 30,000km driving distance to the viscosity of 7.82, viscosity index 3, lubrication 40um and at 75,000km driving distance the viscosity of 76.01, viscosity index 10, lubrication of 88. The lubrication characteristics and quality of lubrication and performance of lubricating oil was changed rapidly for the driving of distance. The result dose not consider the properties of fuel used.

The z-test statistic is one of the most popular statistics. However, this conventional z-test has a serious pitfall when some of observations in a sample are contaminated. We propose two alternatives which satisfy asymptotic normality. We used the median or Hodges-Lehmann estimator instead of the mean and we also used the median absolute deviation or Shamos estimator instead of the standard deviation in the z-test statistic. The proposed alternatives are easy to implement. Thus, it is quite useful for engineers and practitioners. Through extensive Monte Carlo simulations, we obtained the empirical statistical power curves which clearly show that the proposed alternatives outperform the traditional method based on the z-test. A real-data illustration is also provided.
