On the stage of transition from highly centralized government to local self-government in Korea, administrating practice characteristics of the directors of Health Centers is essentially required to be found. This study was conducted in order to find the administration patte군 of the directors of Health Centers in Korea and their opinion on the environment of health administration including personnel management regime for them. The materials were collected from 149 directors of Health Centers with a structured questionaire by mailing. The major findings of this study were as follows. 1. About two-thirds of the directors(69.1%) make plan through the consensus between public service perosonnel in programme department and them in budgt control department. And 75.0% of the directors maintain the planed by the predecessor. 2. More than two-thirds of the directors (71.1%) take subordinates opinion into consideration in case of the programmes facing objections. 3. When the directors face obstacles in pursuing health programmes they usually consult other public service personnel than inhabitants. 4. Only 10.8% of the directors were satisfied with the support of the Ministry of Internal Affairs for health administration while more than half of them were satisfied with the support of health institution in higher level. 5. The directors evaluated the job attitude of the public service personnel in low level as more favorable than that of there higher level public service personnel who work for central government. 6. Only 18.1% of the idrectors were satisfied with their saley. And more than half of them expect the promotion of their position. On the ground of this result the administration attitude of the directors of Health Centers would be evaluated as improved and as more positive than that of other public service personnel in health authorities. However, they are required to consult the inhabitants more frequently for health administration. An the public service personnel in high level who work for central government are required to improve their job attitude.

A design of a 32-bit fourth-stage decimation filter decimation filter used in sigma-delta analog-to-digital (A/D) converter is proposed in this work. A four-stage decimation filter with down-sampling factor of 512 and 32-bit output is developed. A multi-stage cascaded integrator-comb (CIC) filter, which reduces the sampling rate by 64, is used in the first stage. Three half-band FIR filters are used after the CIC filter, each of which reduces the sampling rate by two. The pipeline structure is applied in the CIC filter to reduce the power consumption of the CIC. The Canonic Signed Digit (CSD) arithmetic is used to optimize the multiplier structure of the FIR filter. This filter is implemented based on a semi-custom design flow and a 130nm CMOS standard cell library. This decimation filter operates at 98.304 MHz and provides 32-bit output data at an audio frequency of 192 kHz with power consumption of $697{\mu}W$. In comparison to the previous work, this design shows a higher performance in resolution, operation frequency and decimation factor with lower power consumption and small logic utilization.

Cryptographic protocol design in a two-party setting has of tel ignored the possibility of simultaneous message transmission by each of the two parties (i.e., using a duplex channel). In particular, most protocols for two-party key exchange have been designed assuming that parties alternate sending their messages (i.e., assuming a bidirectional half-duplex channel). However, by taking advantage of the communication characteristics of the network it may be possible to design protocols with improved latency. This is the focus of the present work. We present three provably-secure protocols for two-party authenticated key exchange (AKE) which require only a single round. Our first, most efficient protocol provides key independence but not forward secrecy. Our second scheme additionally provides forward secrecy but requires some additional computation. Security of these two protocols is analyzed in the random oracle model. Our final protocol provides the same strong security guarantees as our second protocol, but is proven secure in the standard model. This scheme is only slightly less efficient (from a computational perspective) than the previous ones. Our work provides the first provably- secure one-round protocols for two-party AKE which achieve forward secrecy.

Most previous works about magnetic effect on plasma emission were interested in emission enhancement which was useful to various fields of plasma application. On the contrary, the following work is interested in plasma dissipation rarely reported in prior researches and expected to help advance plasma-controlling technique. Nd:YAG laser (1064 nm, 6 ns) was focused on three kinds of metals (Al, Ti and STS) and air. The permanent magnetic field (0.4 T) of Nd₂Fe₁₄B magnet was provided passing throughout laser-induced plasma. The spectra of plasma in both the presence and absence of the magnetic field were observed with varying laser power and delay time of the spectrograph. In this work it was uniquely discovered that the plasma always dissipated easily in the presence of magnetic field irrespective of the laser power. With the O I(777.42 nm)-line shape function fitted to Lorentz profile, its half width at half maximum (HWHM) was evaluated to verify that the magnetic field increased the plasma density. It is concluded that magnetic field facilitates not only plasma emission enhancement but also plasma dissipation, increasing recombination rate which is proportional to plasma density.

Art has always been a witness to its time. The art of our century has lived through two world war. In that time Friedensreich Hundertwasser was born to a half Jewish family in Vienna in 1928. He lived and died as a painter, architect, designer, ecologist, writer, innovator... etc. He was impressed form Gustav Klimt, who pioneered the Viennese Secession which was the Austrian expression of the Art-Nouveau mouvement and inspired by the works of Egon Schiele from an early date. His style as an architect was heavily influenced by Antonio Gaudi and some of the Jugendstil architects. Although his architectural work is comparable to Gaudi in its biomorphic forms and use of tile, but is currently renowned for his unique styling. His character as follows; First, Bold color - His use of color is bold, and he has a strong sense of which color work well together. Second, Curved line & Spiral - It's the primary shapes in his works against the tyranny of ugliness and the iron rule of its straight line. Spiral reveal as a transautomaism. Third, Harmony with nature - His work is the creator of beauty, of nature of harmony, peace of joy, against the contradictions of our post-industrial society. He represented these various characteristics in his works. Hundertwasser first achieved notoriety for his boldly-colored painting, he is more widely renowned today for his revolutionary architectural designs.

Purpose: This study was conducted to identify factors related to developmental care performance among neonatal intensive care units (NICU) nurses. Methods: The participants were 139 nurses who had provided care to premature infants for more than 6 months and were recruited from the NICU of 8 hospitals. Data were collected from September 1 to December 1, 2017 through questionnaires that encompassed developmental care performance, developmental care perceptions, and the nursing work environment. Results: More than half (51.8%) of the participants responded that they had never received developmental care education, and for 89.6% of those who had received developmental care education, it was a one-time event. The average developmental care performance of NICU nurses was 0.81, with a range of 0.5~1 point. Multiple regression analysis, demonstrated that the nursing work environment (β=.27, p=.001) and developmental care perceptions (β=.23, p=.004) influenced developmental care performance, with a total explanatory power of 14%. Conclusion: Based on these results, developmental care education for the NICU nurses must be provided systematically. In addition, strategies to improve nurses' perceptions of developmental care and to provide appropriate support for the nursing work environment can promote developmental care performance.

The purpose of this study is both to describe and to explain the shapes and the changes of Kwangju women's productive activities from the middle of 1950's to the end of 1990's. Productive activities in this study include wage labors as well as economic activities in informal labor sector and domestic labor. Three factors - economic structure, the family, and women's consciousness - are drawn to explain women's work in Kwangju. The period from the middle of 1950's to the end of 1990's has been divided into 5 stages and the characteristics of women's work at each stage are as follows : Kwangju women during 1950's worked hard and contributed to the family economy not only inside but also outside the family : during the second stage from 1960's to 1970's, they accomplished not only the traditional women's role but also industrial wage worker : the third period of the first half of 1980's was the time for the development of social consciousness : the fourth period from the end of 1980's to the beginning of 1990's was the time when women tried to solve their problems by themselves: during the last period from the middle of 1990's to the end of 1990's. Kwangiu women wanted to establish their identities in the independent area from their families.

Hitchcock, "a master of the thriller" "leading figure of thriller", was famous for his work style. He never starts filming until completing a perfect conception in his mind before shooting. He started filming after getting a perfect filming plan adding a picture even one detailed shot picture. Also the movie costumes was not an exception in his movie. He put more main object to express a symbolic meanings by recreating movie costumes which were fit to drama′s subject than function which spoke for contemporary popularity also he guides actors to put on the movie costumes examined previously to shape a definite visual character in that works. This research intends not only to look into symbolic and expressive means of dresses through the movie costumes on thriller appeared in Hitchcock′s movie, but also the comprehension width by grasping importance of the movie-costume and dress image in the movie. Hitchock made about 55 movies, mostly thriller movies, from Number 13(1922) n unfinished work to family plot(1976) ones posthumous work. This research examined his the second half of term works(after 1950) such s Rear Window(1954), Vertigo(1958), Psycho(1960), Torn Curtain(19660, Topaz(1969) and Frenzy(1972) which are generally familiar to the public. In conclusion, we can find that the thriller movie costumes as well s the other movie and appeared a character of the film′s characters, social rank, economic level, personality. But expecially, a costume of Hitchcock′s thriller movie can be contained a characteristic factor of a kind of five.

Work roll wear in the cold rolling of mild steel strip is strongly affected by rolling materials, rolling conditions such as roll arrangement in the cold rolling mill and lubrication. The tests were performed to find the effects of roll arrangement n the cold rolling mill on the work roll wear under the same lubricating conditions. The obtained results are as follows:If the distance of cold rolling is about 60km, the surface roughness of its was reduced by half(Ra 0.49${\mu}{\textrm}{m}$) and Pc(peak count) also was decreased to 60 ea/cm.It is easier for CC(Continuous casting) to make a slip on rolling than IC(Ingot casting). It is due to surface mirror in which first residual product appears and iron powder included Al2O3 is sticked. Because bending degree of 4Hi-rolling mill is higher than 6Hi-rolling mill, the first surface mirror was occurred to its center-point which is loaded strongly. 6Hi-rolling mill shape-controlled by intermediate roll doesn't need the initial crown to work roll. Therefore, fatigue and wear would appear a little bit.

In this paper, mechanical properties of mild steel plate which was pretreated by prestress and prestrain loading conditions were studied. The variation of the mechanical properties of the test materials is evaluated in the light of Taylor's work hardening theory. Through this experimental study, it is recognized that material showed unstable phenomena after cyclic loading and it will recover its stability after a certain period of time accompaning the increment of hardness and the yield strength of the material. Also, the strength of smooth specimen, the notch strength of notch specimen and propagation behavior of fatigue specimen which were subjected to prestress and prestrain reveal that the optimal conditions may occur in the first, the middle and the later half of stage II of Taylor's work hardening theory, respectively.
