The aim of this study is to explore an advanced version of value orientation for public organizations by re-examining the orientation of Social Value, which was radically pursued by the Moon Jae-in government. This study finds that the approach was problematic by the Big Society agenda that was a starting point for social value discussions. For this purpose, this study analyzed the Big Society agenda, and then, suggested alternative values and tools in terms of public value and co-production for social value followed by policy implications to make them happen. This study, therefore, acknowledges that current policies and approaches to the social value of public organizations should be changed drastically.

Recently, fuel prices have been continually raised in diesel engine. Such a change in the fuel price influences enormously the development trend of marine diesel engines for slow speed, In other words, the focus was shifted from large diameter and high speed to low fuel consumption. Accordingly, more efforts are being made for engine manufacturing and development to develop highly efficient engines. In this study. a single cylinder 4 stroke cycle DI slow speed diesel engine was designed and manufactured, a 4 stroke cycle was configured and basic performances were evaluated. The results are as follows. The optimal fuel injection timing had the lowest value when specific fuel consumption was in BTDC 8~$10^{\circ}$, a little more delayed compared to high speed diesel engines. Cycle variation of engines showed about 5% difference at full loads. This is a significantly small value compared to the cycle variation in which stable operation is possible, showing the high stability of engine operation is good. The torque and brake thermal efficiency of engine increased with an increase of engine 250-450 rpm. but fuel consumption ratio increased from the 450 rpm zone and thermal efficiency abruptly decreased. Mechanical efficiency was maximally 70% at a 400 rpm that was lower than normal engines according to the increase of mechanical frictional loss for cross head part. The purpose of this study was to get more practical engines by comparing the above results with those of slow speed 2 stroke cycle diesel engines.

Backfire characteristics for hydrogen fueled free piston engine with uni-flow scavenging is investigated with different stroke, exhaust vlave openning timing and fuel-air equivalence ratio by using RICEM (Rapid Intake Compression Expansion Machine) for combustion research of free piston engine. As results, it is found that backfire can be occurred due to slow combustion of unhomogeneous mixture in the piston crevice volume or/and in the cylinder near piston head. And the more stroke of free piston H2 engine with uni-flow scavenging is short the more opening timing of exhaust valve have to be advanced to control backfire.

For predicting the performances of the four stroke cycle spark ignition engines. the gas behavior in the engine system has been analyzed. The calculations consist of two parts. the calculation of the gas behavior in the intake and exhaust systems which was described in the first paper, and the calculation of the variations of gas properties inside the engine cylinders. In this Paper the simulations for the in-cylinder processes were described for the MPI engine, naturally aspirated and turbocharged engines with a carburettor. With the combination of the calculations of the intake and exhaust systems and the calculation of the in-cylinder processes. the predictions of the engine Performances and the exhaust emission characteristics were carried out. And the result showed good agrements with the experimental results under wide range of operating conditions.

Information Effluence leaks are caused by the wide use of the P2P program in Japan and Korea lead by the increase of internet use and network infrastructure expansion. This research confirms the seriousness of the data collected from the P2P leaks of the two countries and furthers its study by researching how countermeasures are applied. The effectiveness is verified by collecting data according to countermeasure applied periods. Both countries had information leaks, but in the case of Japan, not only personal information leaks but corporation, administrative agency, military, and others in a wide range as well. As a countermeasure against information effluence, Korea is enforcing counter plans mainly against the P2P service businesses and for Japan, various plans are taken such as business guides for each agency, organization management, SW development and supply, HW supply, and ect. The leaks in Japan were more severe than the ones in Korea but they had well planned countermeasures that were applied. Therefore if the Japanese countermeasure on information effluence of P2P programs is taken as a lesson, Korea can prevent the problem of leaks beforehand.

In this paper, the scavenging process of various transfer ports was evaluated to improve the performance of a small two-stroke engine for unmanned aerial vehicles. Three-dimensional computational fluid dynamics simulations were performed to four transfer ports for the evaluation, and a three-phase scavenging model was developed and applied to the simulation results for the quantitative comparison of scavenging performance. the short-circuit of fresh charge was restrained and an in-cylinder turbulent kinetic energy was enhanced by changing the transfer port. Also, a difference in the scavenging for each port were confirmed by applying the three-phase model to the simulation results.

This study was conducted to investigate provider's behavior change after releasing the information on the Cesarean section rate. Claims data filed at the National Health Insurance Corporation was used for this analysis and the focus of this study was the change of cesarean rate after the public disclosure of information. Average rates of the year 1999 and 2000 were compared, on the institutional basis, and range and coefficient of variation were estimated. For the last decade, Cesarean section rate has been increased dramatically. Clinical or demographic factors could not adequately explain the increase. Instead, nonclinical factors, such as financial incentive, physician's convenience, practice characteristics, etc., were more significant in explaining the increasing rate. Providers' behavior was significantly affected by the public release of information: after the release, average rate was decreased by 10.2%, and variations were also decreased. In particular, the extent of decrease was explained mainly by nonclinical factor rather than clinical ones. The results suggest that disseminating practice information to providers and consumers could contribute to reducing unnecessary medical service.

대형 저속 2행정기관을 탑재한 선박에서 축계배치와 관련된 선미측 후부 메인엔진 베어링의 손상이 증가하는 경향이 있다. 메인엔진을 포함한 선체는 최적화로 인하여 변형하기 쉬운 경향에 있고, 고출력을 요구하는 추진 축계는 이것과 반대의 경향을 가지므로 축계 배치 변화에 대한 감도가 높아져서 메인엔진 베어링의 손상이 발생하게 된다. 이러한 문제에 대한 대책으로 메인엔진 베어링을 포함한 보다 정확한 배치계산을 할 필요가 있다. 이 논문에서는 축계배치계산 고정도화의 일환으로 메인엔진 베어링 수가 베어링 반력에 미치는 영향에 대하여 검토한다.

Purpose: This study was conducted to compare internal marketing, job satisfaction and customer orientation between nurses in small-medium hospitals and nurses in general hospitals. Method: The participants were 470 nurses were working in 8 small-medium hospitals and 5 general hospitals. Data were collected with structured questionnaires in July, 2010, and analyzed using descriptive statistics, ${\chi}^2$-test, MANCOVA, t-test, One-way ANOVA, and Scheffe test with PASW (SPSS) 18.0 program. Results: There was no significant difference between small-medium hospital nurses and general hospital nurses in internal marketing and customer orientation. But nurses in small-medium hospitals had higher levels of job satisfaction than general hospital nurses. Conclusions: These findings demonstrate the necessity of developing programs that will help to improve job satisfaction in nurses.
