The study proposes some principles that enable local governments to set-up their own civil welfare standard through the public-private partnership in the context of the participation of residents. First, the study analyzes the concept of the civil welfare standard in comparison with the national minimum. In sequence, the study tries to compare various conception, set-up process, fields and contents of the civil welfare standard in 10 local government. And the study suggests a series of some principles for setting-up the civil welfare standard, budget securing, developing core businesses, and reflecting regional characteristics. At last, the study would remind that the process of setting-up and realization of a civil welfare standard could be long-term project through the public-private partnership with civil society organizations, research institutions, local governments and local councils in region.

In this paper, we introduce the concept of split and non-split tree (D, C)- set of a connected graph G and its associated color variable, namely split tree (D, C) number and non-split tree (D, C) number of G. A subset S ⊆ V of vertices in G is said to be a split tree (D, C) set of G if S is a tree (D, C) set and ⟨V - S⟩ is disconnected. The minimum size of the split tree (D, C) set of G is the split tree (D, C) number of G, γ_χST (G) = min{|S| : S is a split tree (D, C) set}. A subset S ⊆ V of vertices of G is said to be a non-split tree (D, C) set of G if S is a tree (D, C) set and ⟨V - S⟩ is connected and non-split tree (D, C) number of G is γ_χST (G) = min{|S| : S is a non-split tree (D, C) set of G}. The split and non-split tree (D, C) number of some standard graphs and its compliments are identified.

This study analyzed the major revision factors and revision contents for 'Construction-Standard-Production-Rate for Construction Works in 2018. Part 16. Pipe Laying Down and Connection" which was revised by the construction expense estimation standard's middle and long-term plans. The main reasons for the revision was analyzed to be unclear construction scope, limitations in applicable pipe material based on the facility type, labor force mainly composed of ordinary workers, limitations of labor force, and incomplete appropriation standard for the tool rent fee and equipment expenses. Through revision of factors, common items were newly established, organization was revised, the labor force was mainly composed of the technicians, and basis for appropriation of equipment expenses was arranged. In addition, through periodic revision, the appropriation standard for bend and special pipes was set. Consequently, more practical construction cost estimate standard is arranged through revision.

The present standard of drinking water quality is not reached to the guidelines of WHO and US EPA recommended. The appraisal of safety is not appropriate by the results of intermittent and limitted analysis. 45 items of drinking water quality are regulated in the Korean standard and 9 items for inspection designated by Seoul City. This report is the results of analysis of the water quality in the water stations of Seoul which are concerned with the items of Korean water quality standard and the priolity pollutnats recommended by WHO. In the results, 45 items of water quality, and the priolity pollutants were not exceeded to the standard and criteria, while DDT, heptachlor-epoxide, THMs, benzo(a)pyrene, Ba, Al, Gross beta, $^{226}$Ra, $^{90}$Sr were detected, the levels were not exceeded to the WHO guidelines. In ordes to evalute the safety of drinking water quality, besides of the existed items of standard, new hazardouse pollutants should be considered monitored continenously. For the regulation of hazardous pollutants, it may be introduced from the risk assessment. According to the relevant assessment, the acceptable risk of pollutants estimated could be applied to set the water quality standard or recommendations or quidelines as well as the number of monitoring.

As the products of internet appliance, such as digital TV, internet set-top box, and internet phone, are continually produced, the market of real time operating system which controls those products is being highly increased. ETRI developed the extensible real time operating system, Qplus-P, which can be used from PDA to internet set-top box and home server. This paper describes the design and implementation of C standard library for real-time operating system Qplus-P. The Qplus-P C standard library follows EL/IX API level, which is proposed to the real-time operating system international standard by the RedHat. And, the C standard library functions, which are needed to support the Tiny-X and Kaffe, are also implemented. The implemented C standard library can reduce the size of library about 30% compare to the C library that does not follow EL/IX API level.

Recently, Intelligent Transportation System (ITS) has been actively developed and built since the Transportation System Efficiency Promotion Act was enacted. However, since mutual connection among transportation information systems was not considered, the integration of transportation information services did not occur. Accordingly, the Ministry of Land Transport and Maritime Affairs established and announced the technical standard on ITS. In this study, the conformance testing of the transportation information and communication system interface standard on data exchange between the Transportation Information Center and terminals was researched The test items were categorized as data request tests and data providing tests by analyzing the communication procedures specified in the standard. A detail testing scenario was created for each item. The test assessment was established based on the conformance of data exchange procedures and the accuracy of data packet messages. Under the established technical standard, the number of times that tests should be performed was thought set to 30 and the success rate was set to 95%. The purpose of this study is to help the ITS of Korea perform the integrated management of transportation information by researching methods for conformance testing on the technical standard on ITS.

A quantitative structure-property relationship (QSPR) study was performed for the prediction of the absorption maxima of azobenzene dyes. The entire set of 191 azobenzenes was divided into a training set of 150 azobenzenes and a test set of 41 azobenzenes according to Kennard and Stones algorithm. A seven-descriptor model, with squared correlation coefficient ($R^2$) of 0.8755 and standard error of estimation (s) of 14.476, was developed by applying stepwise multiple linear regression (MLR) analysis on the training set. The reliability of the proposed model was further illustrated using various evaluation techniques: leave-many-out crossvalidation procedure, randomization tests, and validation through the test set.

Embedded processors often accommodate two instruction sets, a standard instruction set and a compressed instruction set. With the compressed instruction set, code size can be reduced while instruction count (and consequently execution time) can be increased. To achieve code size reduction without significant increase of execution time, this paper proposes a new compressed instruction set architecture, called TOE (Two Operations Execution). The proposed instruction set format includes the parallel bit that indicates an instruction can be executed simultaneously with the next instruction. To add the parallel bit, TOE instruction format reduces the destination register field. The reduction of the register field limits the number of registers that are accessible by an instruction. To overcome the limited accessibility of registers, TOE adapts non-homogeneous register partition in which registers are divided into multiple subsets, each of which are accessed by different groups of instructions. With non-homogeneous registers, each instruction can access only a limited number of registers, but an entire program can access all available registers. With efficient non-homogeneous register allocator, all registers can be used in a balanced manner. As a result, the increase of code size due to register spills is negligible. Experimental results show that more than 30% of TOE instructions can be executed in parallel without significant increase of code size when compared to existing Thumb instruction set.
