This study analyzes the relevance of retention period assigned for each unit task based on the table of records management standards that has been used in schools around the country since January 2011. Retention period, which used to be appropriated on the basis of a record file in the classification scheme, has been re-appropriated on the basis of unit tasks after the table of records management standards have been introduced. However, the new retention period of school records directly apply the 7 retention periods defined for public institutions according to Public Records Management Act. Therefore, this study attempts to analyze the relevance of retention period for school records appropriated for unit task from various angles regarding laws, indexes, survey results, overseas cases.

The purpose of the this study was to provide the basic information about the formation background of urban squatter and their housing state in Korea. This study was progressed on the basis of socio-historical point of view from after the Korean War to the present time. Therefore, this study considered the meaning of housing for urban squatter in the Korean housing history. For this study, the formation background of urban squatter was divided into five periods. The first one was the period of the policy on the mass migration (1955-1960) after the Korean War. The second period was the period of reproduction of deteriorated residential area (1960-1970) for the continuing mass migration policy. The third was the period of disbanding of deteriorated residential area (1970-1980) for redevelopment. The forth period was before the IMF (1980-1997) broke up the deteriorated residential area. The fifth period was after the IMF (1997-) produced the new poverty due to the unemployment and the business failure. Thus, such social change increased the number of urban squatter and created the new type urban poor.

Various ceremonial flags were of great importance to the rulers who wished to have the absolute authorities for governing the people. Perhaps nothing indicated the ideas, thoughts and symbols of a certain period and people than the ceremonial flags. The ceremonial flags used in the old China and Korea took the shapes of the heaven and the earth, representing the social backgrounds and thoughts. This study was limited only to the discussion of the heaven-shaped patterns of the ceremonial flags. The 28 constellations of the heaven, in the Oriental way of thinking, were considered to express the immortal powers of Providence and the political domination of the earth. Hence the Polaris, the center of the heaven, symbolized the whole family of king, prince, child born of a concubine and royal harem. Among the constellation pictures were those of Han period, wall painting of old tombs in Koguryeo kingdom and old Japanese kingdom. Referring to the Emperor's ceremonial flags in Daemyeongjibyei, symbolic meanings changed historically and the complete systems of the ceremonial flags were established in Song period when the divine person was drawn on the flags. Animals concerned properly with the particular star and the shapes of the star were both drawn on the flags in Won period and only the shapes of the particular star in Myeong period. In the Imperial enthronement of Kojong the ceremonial flags might be made by the examples of those of Myeong period and remains are now found at Changdeok Palace, which need a further study because the references in detail are not available.

A dapo type bracket system which consists of chuganpo(柱間包) and chusangpo(柱上包) with a fake-beam adopted a nemok-dori member to cope with oemok-dori member in order to obtain balance between the outer-side and the inner-side of the bracket system. The middle part of the longest rater in the dapo system is supported by three points made by oemok-dori, jusim-dori and nemok-dori members and the area between the rafer supporting points forms a supporting area. The increase of rafter supporting points and supporting area leads to heightening the structural stability and the efficiency of load delivery. In the eave of dapo system the portion where the three supporting points formed by oemok-dori, jusim-dori and nemok-dori members shows as 33% in the early period, 71% in the middle period and 78% in the later period. On the contrary the portion where more than one of the three dori members were omitted shows as 67% in the early period, 29% in the middle period and 22% in the later period. This is the result of the increase of the number and the distance of steps in the dapo bracket system as time goes on. This is because the structural role of three supporting points becomes important as the increase of distance between the dori members leads to the increase of load which burdens on each dori member.

Purpose: This study was conducted to examine the effect of education on infection control for multidrug resistant organism (MDRO). Methods: One group pre-post time series design was used. Infection control education for MDRO infection was provided to nurses working in the Neonatal Intensive Care Unit (NICU). Knowledge and recognition were evaluated before and after education. Hand hygiene compliance, MDRO isolation rate and central line-associated bloodstream infection (CLABSI) rate were used as outcome variables. Data from 45 nurses was used for analysis. Results: General knowledge about MDRO increased (p=.011). Responses to questions about image of MDRO and MDRO management tended to change in a positive direction (p=.046). Hand hygiene compliance was 100% at pre-test, 79.5% during education period and 98.4% at post-education period. MDRO isolation rate was 6.83 per 1,000 patient days at pre-test, 10.24 during education period and 6.68 at post-education period. CLABSI rate was 3.76 per 1,000 central line days at pre-test, 6.84 during education period and 4.71 at post-education period. Conclusion: Findings indicate that the education program is effective in improving knowledge about MDRO in NICU nurses. However, more reliable indicators should be used to determine long-term effects.

Purpose: The purpose of this study was to examine and analyze the post operative fasting period of neonates in the intensive care unit (ICU) after receiving open heart surgery in order to provide optimal nutrition support for these neonates. The variables included biochemical nutrition indexes (albumin, total lymphocyte count, total cholesterol) and patient outcomes (duration of mechanical ventilation, ICU stay, hospital stay, infectious complication). Methods: The participants were 124 neonates in ICU after receiving open heart surgery, and the design of this study was to investigate their post operative fasting period retrospectively to analyze the biochemical nutrition indexes and patient outcomes according to post operative fasting period. Results: The results for 4 groups according to post operative fasting period showed that the group with less 48 hours of fasting had the best biochemical nutrition indexes and patient outcomes, followed by the 48-72 hour group, the 72-144 hour group, and the over 144 hour group. Conclusion: The results indicate that for new born babies receiving open heart surgery, the period of fasting after the operation should be minimized and tube feeding should be started as soon as possible.

Recently in-memory data stream processing has been actively applied to various subjects such as query processing, OLAP, data mining, i.e., frequent item sets, association rules, clustering. However, finding regular periodic patterns of events in an infinite data stream gets less attention. Most researches about finding periods use autocorrelation functions to find certain changes in periodic patterns, not period itself. And they usually find periodic patterns in time-series databases, not in data streams. Literally a period means the length or era of time that some phenomenon recur in a certain time interval. However in real applications a data set indeed evolves with tiny differences as time elapses. This kind of a period is called as a pseudo-period. This paper proposes a new scheme called FPMH (Finding Periods using Multiple Hash functions) algorithm to find such a set of pseudo-periods over a data stream based on multiple hash functions. According to the type of pseudo period, this paper categorizes FPMH into three, FPMH-E, FPMH-PC, FPMH-PP. To maximize the performance of the algorithm in the data stream environment and to keep most recent periodic patterns in memory, we applied decay mechanism to FPMH algorithms. FPMH algorithm minimizes the usage of memory as well as processing time with acceptable accuracy.

The mutual relation dynamics between the chulik and the Po for man in the period of chosun dynasty. The objectives of this study are to find out the mutual relation between the chulik and the Po for man-symeui, danryeong, changeui, jikryeong-, te change of chulik, and the ideas that made this change. Conclusions are decribed as followes: 1. The pattern of chulik and symeui is same, and they consist of bodice and skirt's length of the chulik was 1 : 1.3∼2 and it is effected by symeui. And symeui was effected by pratical structure of the chulik. 2. The functions of the chulik were the underwear of danryeong and the upperwear as military uniform. And then the length of chulik was shorter than danryeong in the early period of shosun dynasty. The sleeves were changed as large as danryeong in the late period of chosun dynasty. It is assumed that the changes were to be a functional underwear and to appear authority as upperwear. 3. Chulik as the underwear was hardly worm in the 17th centuries, and changeui was widely enjoyed instead of it. The reason of this change is that the pragmatism was emphasied in that period. 4. Chulik was widly worm instead of court dress, until the mid of 17th century after war. It was effected by outer factor of the war. And jikryeong was widly worm instead of chulik in the late period of chosun dynasty. It shows that military officers wanted to appear authority.

Growth monitoring of highland Kimchi cabbage is very important to respond the fluctuations in supply and demand from middle of August to early September in Korea. For evaluating Kimchi cabbage growth, it needs to classify the transplanting period of Kimchi cabbage, preferentially. This study was conducted to estimate the transplanting period of highland Kimchi cabbage from 2015 to 2016 in the main production area of highland Kimchi cabbage, Anbandegi, Maebongsan, and Gwinemi. Correlation between NDVI (Normalized Difference Vegetation Index) from UAV images and days after transplanting of Kimchi cabbage was high in early transplanting period. But because the growth curve of Kimchi cabbage showed S-type, joint use of multi-temporal linear regression equation for estimation of transplanting period was more suitable. Using application of these equations at Anbandegi, Maebongsan, and Gwinemi, we made the map of transplanting periods of highland Kimchi cabbage. Generally, highland Kimchi cabbage is harvested in sixty days later since transplanting. As a result, we could estimate the harvest time and area of highland Kimchi cabbage.

Objective: In children with acute otitis media, we investigated the relationship between state of tympanic membrane and treatment period by video otoscope. Methods: Ten children(6 boys, 4 girls) with acute otitis media were assigned to one of three groups. In the grade I, there were redness in the tympanic membrane. In the grade II, there were bulging, effusion with exudate, dark color in the tympanic membrane. In the grade III, there were effusion with purulent exudate or cholesteatoma with serous exudate. And we investigated the treatment period in each group. Results: Overall, the $mean{\pm}S.D.$ on the treatment period in the grade I was shorter than grade II. It was $12.6{\pm}5.18$ in the grade I versus $26{\pm}2.83$ in the grade II. That in the grade II was shorter than grade III. It was $26{\pm}2.83$ in the grade II versus $148{\pm}43.03$ in the grade III. Conclusions: Although we couldn't have enough cases in each group. we could predict the conclusion that there was the relationship between treatment period and state of tympanic membrane.
