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.

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.

국내 블록암호표준(안)으로는 SEED암호가 있다. 이 암호는 한국정보보호진흥원(KISA)이 1998년 10월에 초안을 설계하고 같은 해 12월에 공개검증과정을 거쳐 안전성과 성능이 개선된 최종 수정안을 발표하였다. DES와는 달리 128비트 블록암호로서 여러 과정을 거쳐 2005년에 국제표준으로 확정되었다. DES와 같은 페이스텔 구조를 가진 블록암호로서 다만 입력비트블록이 DES의 두 배인 128비트로 늘어났다는 것이다. 본 논문에서는 첫째, SEED 암호의 일반적인 알고리즘을 소개하고 F-함수에서 적용되는 열쇠 값의 생성원리를 수학적으로 분석해 보았다. 둘째, S-함수의 8비트 입력 값에 대응되는 원시원소 ${\alpha}$ 의 멱승 값을 계산하는 표를 도출해 보았으며 마지막으로 G-함수 내에 설계되어져 있는 S-함수의 계산 원리를 수학적인 방법으로 새로운 정리와 예제를 통해 분석해 보는 것으로 한정하였다. 이러한 과정을 통하여 현재 알려져 있는 SEED암호의 취약점을 보완할 수 있는 새로운 암호체계를 개발하는데 필요한 아이디어와 이론적인 근거를 제공하는 데 어느 정도 도움이 되고자 한다.

우리나라는 1960년대 이후 대외지향적 성장정책을 추구하여 괄목할 만한 성과를 거두었다. 즉 원자재와 부품을 수입하여 이를 제조 가공 수출함으로써 경제발전을 이루었던 것이다. 따라서 우리나라의 항만산업은 대외교역을 뒷받침하는 기간산업으로서 핵심적인 역할을 수행해 왔다. 항만산업의 발전은 자체적인 부가가치 생산 및 고용창출효과 이외에도 국민경제 전반의 물류효율화 및 물류비절감에 기여함으로써 대외경쟁력을 향상시키게 된다. 이러한 항만산업의 경제적 중요성에도 불구하고 이에 대한 국민적 인식은 대체로 낮은 편이다. 그리고 우리나라 항만산업의 발전여건은 상당히 열악한 편이며 특히 우리나라 주요 선사들의 선박확보량을 감축하는 추세에 있다. 따라서 본 연구에서는 항만관련 산업이 지역경제에 미치는 영향을 지역산업연관표를 이용하여 살펴보는데 연구의 목적이 있다. 정책적 시사점을 제시하면, 국가의 기반산업을 시장논리로만 접근할 경우 시장실패시치러야할 대가가 매우 크기 때문이다. 또한 우리나라 자체적인 항만산업을 유지하고 발전없이 외국에 의지할 경우, 국가비상시의 수송수단 확보, 외국업체들의 담합에 의한 운임상승, 국내하주들의 안정적인 운송수단 확보 등에 있어서 문제가 야기될 경우 국가 경제에 미치는 영향은 막대할 수 있다. 정부와 관련업계는 컨테이너 화물 유치를 위해 온갖 노력을 기울이고, 적극적인 항만마케팅전략을 수립해야 한다. 또한 부가가치 창출에 힘쓰는가 하면 항만배후지역을 보세구역화하여 수출입물량의 가공, 포장 등을 통해 재수출하도록 지원해야 한다.

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.
