The purpose of this study was to investigate the differences in traditional baby-delivery practices between young mother and grandmother generations. The subjects were 118 young mothers and 118 their own mothers or mothers-in-law in Tae Gu district. Young mothers had the first baby aged from 2-to 2.5-year-old. The subjects answered the questionnaires on Korean traditional baby-delivery practices developed by the researchers based on literature reviews. The data were analyzed using Frequencies, Percentages, Crosstabs, and t-test. The results of this study were as follows: 1. More grandmothers believed in supernatural being who influenced pregnancy and used to be called as 'grandma Sam Shin', expected to have son, and had charms then young mothers. But less grandmothers had sexual intercourse at the time of ovulation, took physical care, and practiced fetal education than young mothers 2. On the other hand, no generation differences were found in dreaming of foretelling conception(Te Mong), eating a restroative and food to get pregnancy, and washing own's hair or body and avoiding attending a funeral near the time of baby-delivery. 3. Most of young mothers gave birth in hospital with the doctor's heap, whereas most of grandmothers did at their home with the help of the experienced old women. Most of young mothers'husbands were at the waiting room in the hospital, but about half of grandmothers'husbands were at work when their wives grove birth.

The market demand for knitwear has been increased both domestically and in export. Despite of the high and consistent demand, knitwear design has been rather simple and tends to show mainly foreign influences. In order to compete efficiently in the world market and to provide more variety, knitwear design originated from our cultural background needs to be developed. Therefore, the purpose of this study is to develop various knitwear design adopting the Korean traditional 'Danchung' motifs and the main colors used in the motifs. Three knitwear works were designed and constructed, which included a round pullover, a half-sleeve V-neck one-piece dress, and an evening dress. The mainly used motifs consisted of natural motifs such as lotus, cloud, and motifs symbolizing good luck such as 壽 and 囍. The Original 'Dan-chung' motifs were stylized into different forms and colors, and this design work was done using CAD system including the 'Adobe Illustrator 9.0' and the '4D box Hi-Knit Program'. Based on the designed images created by the CAD system, an actual design works were knitted using different weft knit methods including a hand knitting machine and weft knit machine of the knitwear manufacturers. This study provided the possibility of knitwear design originated from the Korean traditional culture.

This paper summarizes the experimental vibration-based structural health monitoring study on a historical monument in Jordan. In this work, and within the framework of the European Commission funded project "wide-Range Non-Intrusive Devices Toward Conservation of Historical Monuments in the Mediterranean Area", a seven and a half century old minaret located in Ajloun (73 km north of the capital Amman) is studied. Because of their cultural value, touristic importance and the desire to preserve them for the future, only non-destructive tests were allowed for the experimental investigation of such heritage structures. Therefore, after dimensional measurements and determination of the current state of damage in the selected monument, ambient vibration tests are conducted to measure the accelerations at strategic locations of the system. Output-only modal identification technique is applied to extract the modal parameters such as natural frequencies and mode shapes. A Non-linear version of SAP 2000 computer program is used to develop a three-dimensional finite element model of the minaret. The developed numerical model is then updated according to the modal parameters obtained experimentally by the ambient-vibration test-results and the measured characteristics of old stone and deteriorated mortar. Moreover, a parametric identification method using the N4Sid state space model is employed to model the dynamic behavior of the minaret and to build up a robust, immune and noise tolerant model.

A general household survey was carried out in the village of Sonoageng in East Java, Indonesia with the aim to assess their socio-economic status, and the crop and livestock production system prevailing in the area. Of the households interviewed (164), 52% are landless, 35% own land or have a combination of own and shared land, and 12% do not own land but have access to land by sharing. Nearly two thirds (65%) of the households raise cattle; most of them own animals, 8% reared shared animals only. The dominant crop was rice; other crops grown were soya bean, groundnut, maize and sugar cane. Nearly half (47%) the household income was derived from off-farm work (non-agricultural activities), 33% from crops, 13% from livestock (mainly cattle), and 7% from agricultural labour. Most households kept 1 to 2 animals and only 21 out of 164 households earned more than Rp. 500,000 (~250 US$) per annum from livestock. The most prevalent type of livestock production in the area could be characterized as small-scale cow/calf operation, either by landless households or those with <0.4 ha of land.

In this research, IAQ is measured to evaluate the emission performance of VOCs in three new apartment houses finished by totally EFMs (Environmental Friendly Material), partially installed EFMs and general materials. Among various VOCs, Target pollutants for the IAQ measurement are benzene, ethylbenzene, toluene, xylene, 1,4-Dichlorobenzene and formaldehyde. The measurement is conducted one day after each interior finishing material is worked over by construction schedule. The result of this research concluded that (1) Except toluene, the concentration levels of each pollutant did not exceed the national IAQ standards in all test residences, (2) As the interior finishing work schedule, A toluene level peaked when the furniture installing was ended. (3) The toluene concentration level of the house installed general interior materials as the non-EFMs furniture was one and half higher than other houses. Consequently, installing. the furniture made by EFMs is one of effective methods to improve the IAQ for new apartment houses.

An efficiency improving method for Uninterruptible Power Supply System(UPS) was developed by using OP-AMP based application circuits such as voltage detection device, current detection device and static switch control device. The efficiency improving algorithm was made by mixing the operating concepts of On-Line type UPS with the operating concepts of Off-Line type UPS. The UPS' inverter does not work if the UPS' output load current is not higher than the low load operating current which is about 0-30(%) of the UPS' output load capacity. The low load operating current is adjustable within the half of the UPS' output load capacity. If the UPS' output load current is rising over than the low load operating current, the UPS' inverter starts working and the inverter output power feeds to the loads of UPS. If UPS' input power breaks out while UPS' inverter does not operate because the load current is low, the inverter starts working within 4(ms) with excessive output voltage which is ${\pm}$8(%) of normal UPS' output voltage. Like these. UPS can continuously feeds power to it's load device and reduce power consumptions.

Purpose: The purpose of this study was to identify the factors affecting shiftwork tolerance among nurses and provide basic data, ultimately, in formulating a plan for improving their shiftwork tolerance. Methods: The participants were 317 nurses who were working at three general hospitals in Daejeon and Seoul. Data analyzed t-test, ANOVA, correlation analysis, and regression analysis using SPSS 20.0 program. Results: As for the sub-areas of shiftwork tolerance for the respondents, more than a half of nurses working at shifts suffered from insomnia, felt drowsy, complained of chronic fatigue, and were at the anxious and depressed state. Shiftwork tolerance differed by the daily intake of coffee and exercise. Shiftwork tolerance was significantly positively correlated with sleep-wake habits, hardiness, and flexibility and negatively correlated with a languidity. Regression analysis revealed that shiftwork tolerance was affected by age, sleep-wake habits, languidity, flexibility, and hardiness. Conclusion: To put the results, nurses had shiftwork tolerance affected by sleep-wake habits, languidity, and hardiness. It is therefore necessary to make a scheme for allowing nurses to improve hardiness and flexibility and decrease the languidity with the objective of improving their shiftwork tolerance.
