In this paper, we compare three mehods to obtain PSD of HRV - FFT, AR modeling, and residual integration. Using these methods we speculate the balances of the LP and HF powers of HRV at $0^{\circ}$, $45^{\circ}$, $90^{\circ}$ tilt levels of head-up tilt table for young and healthy 24 men. R peaks are located at the highest point of QRS complex detected from modified spacial velocity algorithm. In general FFT is the most fast way to obtain PSD but PSD from FFT has too many peaks and valleies. AR PSD can show frequency of ANS activity effectively but LF component of PSD is often invisible due to interference of VLF power. The residual integration method that decomposes the AR PSD is very efficient way to extract LF component. Applying the above three methods to HRV we can visualize the trend of PSD variations along tilt levels.

HDF5 data format is used to effectively store and distribute large volume of Geostationary Ocean Color Imager(GOCI) satellite data. The Korea Ocean Satellite Center has developed and provided a GOCI Data Processing System(GDPS) for general users who are not familiar with HDF5 format. Nevertheless, it is not easy to merge and process Hierarchical Data Format version5(HDF5) data that requires an understanding of satellite data characteristics, needs to learn how to use GDPS, and stores location and attribute information separately. Therefore, the open source R and rhdf5, data.table, and matrixStats packages were used to develop algorithm that could easily utilize satellite data in HDF5 format without the need for the process of using GDPS.

Purpose: The purpose of this study was to explore the fatigue of the mothers of the hospitalized children's mothers in descriptive study. Method: Two hundred eighty three mothers who take care of the hospitalized children in three University hospitals were enrolled from June, 1 to October, 30, 2003. Data were collected using a questionnaire titled 'Symptom Table on Fatigue Perception' designed by the Fatigue Research Committee of Japan, consisted of a total 30 items categorized into three sub-dimensions: the physical, the psychological and the neuro-sensory. SPSS was used for the analysis of data with 0.05 of significance. Result: 1) The mean average fatigue score of subjects was 1.94(SD:.48): the physical fatigue revealed the highest value with a mean of 2.19(SD:.57), followed by psychological fatigue with a mean score of 1.85(SD:.52), neuro-sensory fatigue with a mean of 1.79(SD:.51). 2) With the respect to the general characteristics of hospitalized children and mothers, there were statistically significant differences in the mothers' fatigue perception by the child sex(t=-2.697, p=.008), the character of child(F=9.032, p=.000), the child condition compared to pre-hospitalization(F=3.523, p=.031), with or without support in domestic households(t=-1.981, p=.049), the amount of sleeping time(t=2.704, p=.007), and with or without of night-time sleep disturbance because of the child hospitalization(t=2.082, p=.038). Conclusion: These results suggest that health care professional need to be aware of the persistent presence of the maternal fatigue related to the child hospitalization and the factors worsen the degree of the fatigue.

There is SEED cryptosystem in domestic block cipher standard. This code was drafted by the Korea Information Security Agency (KISA) in October 1998 and underwent a public verification process in December of the same year, which resulted in the final amendment to improve safety and performance. Unlike DES, it is a 128-bit block cipher that has been passed through various processes and established in 2005 as an international standard. It is a block cipher with a pastel structure like DES, but the input bit block has been increased to 128 bits, double DES. In this paper, first, we introduce the general algorithm of SEED cryptosystem and analyzed mathematically generating principle of key-value which is used in F-function. Secondly, we developed a table that calculates the exponent of the primitive element ${\alpha}$ corresponding to the 8-bit input value of the S-function and finally analyzed calculating principle of S-function designed in G-function through the new theorem and example. Through this course, we hope that it is to be suggest the ideas and background theory needed in developing new cryptosystem to cover the weakness of SEED cryptosystem.

Korea has achieved a remarkable growth by pursuing externally-oriented growth policy since 1960s. That is, we imported raw materials and spare parts, manufactured them into products and exported them, which led to successful economic development. Therefore, our marine business has played an important roles as one of key industries. The development of marine business has contributed to efficient distribution and cost reduction in addition to production of added value and creation of employment creation, which improved external competitive power. In spite of economic importance of marine business, national perception on it is in general low and its developmental conditions are considerably poor. Therefore, this study aims to speculate the effect of Port-related business on regional economy using regional input-output tables.

Mold grows more easily when humidity is higher in indoor spaces, and as such is found more often on wetted areas in housing such as walls, toilets, kitchens, and poorly managed spaces. However, there have been few studies that have specifically assessed the level of mold in the indoor spaces of water-damaged housing in the Republic of Korea. We investigated the levels of airborne mold according to the characteristics of water damage types and explored the correlation between the distribution of mold genera and the characteristics of households. Samplings were performed from January 2016 to June 2018 in 97 housing units with water leakage or condensation, or a history of flooding, and in 61 general housing units in the metropolitan and Busan area, respectively. Airborne mold was collected on MEA (Malt extract agar) at flow rate of 100 L/min for 1 min. After collection, the samples were incubated at $25^{\circ}C$ for 120 hours. The cultured samples were counted and corrected using a positive hole conversion table. The samples were then analyzed by single colony culture, DNA extraction, gene amplification, and sequencing. By type of housing, concentrations of airborne mold were highest in flooded housing, followed by water-leaked or highly condensed housings, and then general housing. In more than 50% of water-damaged housing, the level of airborne mold exceeded the guideline of Korea's Ministry of Environment ($500CFU/m^3$). Of particular concern was the fact that the I/O ratio of water-damaged housing was greater than 1, which could indicate that mold damage may occur indoors. The distribution patterns of the fungal species were as follows: Penicillium spp., Cladosporium spp. (14%), Aspergillus spp. (13%) and Alternaria spp. (3%), but significant differences of their levels in indoor spaces were not found. Our findings indicate that high levels of mold damage were found in housing with water damage, and Aspergillus flavus and Penicillium brevicompactum were more dominant in housing with high water activity. Comprehensive management of flooded or water-damaged housing is necessary to reduce fungal exposure.

The purpose of this study was to identify a relationship between housework hours and fatigue level in middle-aged women. The subjects were 204 women living in Seoul and near the city, ranging in ages of 30-59(mean = 41.6 year) and were interviewed during the month of Oct. to Dec. 1999. The following questionnaires were utilized in this study: a self reporting housework time measurement table and a fatigue symptom scale originated from Yoshitake (1978). The analysis of the data was done by SAS program, t-test, ANOVA, and Pearson correlation. The results of this study were as follows : 1. Total mean hours of housework of the subjects were shown 9.2 hours on weekdays and 8.9 hours on weekend. Mean hours according to the area of houseworks on weekdays and on weekend were preparing and providing meal 3.9 and 4.2, doing laundry and maintaining clothes 3.1 and 1.6, keeping and maintaining house 1.6 and 1.4, caring family 1.3 and 1.2, and keeping household records 0.5 both. 2. With respect to the general characteristics of the subjects, there were significantly difference in age, job, religion, type of family, number of children, experience of present and previous illness, and perceived body size. 3. Average fatigue scores of the subjects were 16.6 of total score 60. Fatigue scores by the area were neuroperceptive fatigue 6.5, mental fatigue 5.2, and physical fatigue 4.9 in order. There were significantly differences in the score of fatigue by religion, number of family, present illness, and perception of body size. 4. There were significantly positive relationships in the scores of fatigue with the total hours of housework, preparing and providing meal, doing laundry and maintaining clothes, keeping and maintaining house, and caring family. 5. The physical fatigue scores were positively related with the areas of preparing and providing meal, doing laundry and maintaining clothes. While the mental fatigue scores were positively related the areas of preparing and providing meal, caring family, and keeping and maintaining house, and neuroperceptive fatigue scores were positively related with the areas of keeping and maintaining house and caring family. The recommendations from this study were further studies to investigate how middle-aged women manage their fatigue level, increase public awareness of middle aged women's fatigue level, and develop programs for middle-aged women to help with high fatigue.

Objective : The recently reported Wuqian edition(吳遷本) Jinguiyaolue(金匱要略) is known to be written in small letters unlike other large lettered versions of the book. The Wuqian edition(吳遷本) takes after the name of Wuqian who copied an ancient version that was found at the time(Ming dyanasty, 1395). It is known to differ in organization and contents to other versions. In this study, I would like to examine how the small-lettered version of the Jinguiyaolue had been created, through a thorough examination of the Wuqian edition, and evaluate its value as a new version of the Jinguiyaolue. Method : First, the systems of both large-lettered and small-lettered versions of the "Jinguiyaolue" were briefly examined, followed by comparison from chapter 1 to 22, of organization, contents, and formulas between the oldest version of the large-lettered versions, the Deng-zhen edition, and the newly discovered Wuqian edition of which examples of each item are listed. The original source was identified for parts that were different. Result & Conclusion : 1. The Deng-zhen edition and Wuqian edition show vast differences in the organization, table of contents, name of chapter, location of each verse or line, existence of certain verses or lines, name of formula, quantity of medicinal ingredients, processing methods and other aspects. 2. The small-lettered edition was published based on the large-lettered edition of the Jinguiyaolue published by the Jiaozheng-yishuju(校正醫書局) after a general cross-examination process followed by selection, modification and supplementation of the large-lettered edition. Reference texts used in cross-examination were Qianjinyaofang(千金要方), Waitaimiyao(外臺秘要), Maijing(脈經), and Shanghanlun(傷寒論). 3. Considering Wuqian's own annotations and preface, it is clear that he wanted to create the best version of the "Jinguiyaolue". Wuqian himself seems to have had professional knowledge of bibliography and medicine.
