  • Neutral detergent fiber(NDF) were extracted from the Nampung, Milyang #23, Whasung and Jinhung varieties of rice by neutral detergent fiber method. To determine the properties of NDF three factors were measured : water-binding capacity(WBC), Fe-binding capacity and sodium taurocholate binding with NDF. The average WBC of NDF was $5.60{\pm}0.87gH_2O/g$ NDF, and the average Fe-binding capacity ranged from 24.63% at pH 5.0 to 19.6% at pH 6.0 and 48.98% at pH 7.0. Binding of sodium taurocholate with NDF was determined in vitro using C-14 labeled sodium taurocholate at 100M sodium taurocholate concentrations. NDF binding of Jinhung was 27.87 while Nampung, Milyang #23 and Whasung measured 32% each. When sodium taurocholate concentrations were raised from $40{\mu}M\;to\;240{\mu}M$ the tendency of binding increased as the concentrations increased, but not linearly.

  • Currently, as a consequence of PACS (Picture Archiving Communication System) implementation many hospitals are replacing conventional film-type interpretations of diagnostic medical images with new digital-format interpretations that can also be saved, and retrieve However, the big limitation in PACS is considered to be the lack of mobility. The purpose of this study is to determine the optimal communication packet size. This was done by considering the terms occurred in the wireless communication. After encoding medical image using JPGE2000 image compression method, This method embodied auto-error correction technique preventing the loss of packets occurred during wireless communication. A PC class server, with capabilities to load, collect data, save images, and connect with other network, was installed. Image data were compressed using JPEG2000 algorithm which supports the capability of high energy density and compression ratio, to communicate through a wireless network. Image data were also transmitted in block units coeded by JPEG2000 to prevent the loss of the packets in a wireless network. When JPGE2000 image data were decoded in a PUA (Personal Digital Assistant), it was instantaneous for a MR (Magnetic Resonance) head image of 256${\times}$256 pixels, while it took approximately 5 seconds to decode a CR (Computed Radiography) chest image of 800${\times}$790 pixels. In the transmission of the image data using a CDMA 1X module (Code-Division Multiple Access 1st Generation), 256 byte/sec was considered a stable transmission rate, but packets were lost in the intervals at the transmission rate of 1Kbyte/sec. However, even with a transmission rate above 1 Kbyte/sec, packets were not lost in wireless LAN. Current PACS are not compatible with wireless networks. because it does not have an interface between wired and wireless. Thus, the mobile JPEG2000 image viewing system was developed in order to complement mobility-a limitation in PACS. Moreover, the weak-connections of the wireless network was enhanced by re-transmitting image data within a limitations The results of this study are expected to play an interface role between the current wired-networks PACS and the mobile devices.

  • The purpose of this study was to provide the basic data for establishing school education environment protection measures, on the basis of comparing and analyzing the realities and students' recognition degree of the environment and hygiene around the middle and high schools located in the rural areas. These study data were investigated by the self-administered questionnaires, taking as subject the 805 students in the middle and high schools located rural areas. And the results were as follows: First, as the result of having investigated the distribution degree of harmful environment within the purification zone around schools, it was found out that students responded: within the purification zone around the middle school, there were cartoon rooms (46.2%), electronic game rooms (45.9%), and singing rooms (45.0%). within the purification zone around the high school, there were electronic game rooms (46.3%), singing rooms (42.3%), billiard halls (41.4%), PC rooms (40.1 %), and Soju-room (35.2%). Secondly, as having analyzed student's recognition degree of the harmful environment around the school, it was found out that middle school students responded that sexual utensils-treating shops (3.74 points) were most harmful, and next corrupted bathhouses (3.52 points), and Soju-room (3.47 points), and high school students also responded relating to harmfulness in a similar sequence. Thirdly, in case of students' recognition degree of the harmful environment around the school according to general characteristics, 1) girl students had a higher ratio of recognition that the environment around the school was harmful than boy students (p〈0.001). 2) groups of students whose living standard was high had a higher ratio of recognition that the environment around the school was harmful than groups of students whose living standard was low (p〈0.05). 3) groups of students whose school was located near the park or the residential street had a higher degree of recognition that the environment around the school was harmful than groups of students whose school was located near the factory or the shopping area (p〈0.01). 4) groups of students whose school was located near the park or the residential street had a higher degree of recognition that the environment around the school was harmful than groups of students whose school was located near the amusement area or the shopping area (p〈0.05). Fourthly, 1) relating to the harmful shops where they experienced most highly the behavior of drinking and smoking, middle school students responded that they did so in the electronic game room (22.5%) and high school students did so in the singing room (31.4%), and high school students had a very high experience ratio of drinking and smoking, compared with middle school students (p〈0.001). 2) relating to the harmful shops where they could get in contact with lewd articles, both of middle school students (5.3%) and high school students (8.3%) responded that they could do so in the video room. 3) relating to the harmful shops where they experienced unsound opposite sex acquaintance, both of middle school students (5.8%) and high school students (16.6%) responded that they did so most highly in hotels, and high school students had a remarkably high experience ratio of unsound opposite sex acquaintance, compared with middle school students (p〈0.05). 4) relating to the harmful shops where they experienced violence, middle school students responded that they did so in the electronic game room (14.0%) and then in the singing room (3.7%), and high school students responded that they did so in the electronic game room (9.3%), the nightclub (4.6%), Soju-room (4.1 %), and high school students had a remarkably high experience ratio of violence, compared with middle school students (p〈0.05). 5) relating to the harmful places where they experienced drugs both of middle school students (0.8%) and high school students (2.4%) responded that they did so in the hotels. Fifthly, when going to the harmful shops, students had the experience of being guided and regulated roughly 1 time - 2 times, and middle school students (16.4%) and high school students (16.7%) had almost similar experience ratios of being guided and regulated. Conclusively, there was a limit in controlling the environment and purification zone only by legal regulations and institutional controls, the self-control purification effort for the school and the surrounding environment was required greatly, in order to protect students from harmful environment. In addition, the constant study to establish the educational environment purification measures must be carried out.

  • Purpose : This study was designed to figure out the necessity of continuing basic CPR education for the higher grade students of elementary school. The assessment contents were knowledge, practice ability, precision level of CPR skills and continuation of the educational efficiency. Methods : Twenty two students of 4th and 5th grade of elementary school in K city in Chungcheongnam-do were recruited for this study. The study method was a control group of non-synchronized design. A preliminary study was done on October 27 in 2006. The main study was performed from February 14 to May 11 in 2007. The researcher adopted the method of Kyung-hui, Kang (1998) such as awareness, attitude and knowledge in control group, emergency medical technician test protocol, Anne/SkillReporter$^{(R)}$ in case of the basic CPR knowledge. Four times of measures were done in shortly after practicing CPR, 4 weeks after the education, 8 weeks after the education, and 12 weeks after the education. By using SPSS/PC+ (version 12.0), the researcher analyzed the collected data based on frequency, percentage, repeated measurement, ANOVA (analysis of variance), and sidak (multiple comparison - sidak). Results : 1) The confidence of people in the control group in terms of practicing CPR showed a statistically meaningful difference (t = 10.230, p = .000) before/after CPR education. Therefore, hypothesis No.1-1 was accepted. 2) The educational necessity of people in the control group showed no statistically meaningful difference (t = -1.695, p = 0.105) before/after CPR education. Therefore, hypothesis No.1-2 was rejected. 3) The knowledge points of people in the control group showed a statistically meaningful difference (t = -7.731, p = .000) before/after CPR education. Therefore, hypothesis No.2 was accepted. 4) The confidence of people in the control group in terms of practicing CRP showed no meaningful difference (F = 2.789, p = 0.072) as time passed. Therefore, hypothesis No.3 was rejected. 5) The knowledge of people in the control group showed a meaningful difference (F = 9.090, p = .000) as time passed. Therefore, hypothesis No.4 was accepted. 6) The capability of people in the control group in terms of practicing CPR showed a statistically meaningful difference (F = 42.795, p = .000) as time passed. Therefore, hypothesis No.5 was accepted. 7) The precision level of CPR skill of people in the control group showed a statistically meaningful difference (F = 25.198, p = .000) as time passed. Therefore, hypothesis No.6-1 was accepted. 8) The precision level of chest compression skill of people in the control group showed a statistically meaningful difference (F = 5.188, p = .003). Therefore, hypothesis No.6-2 was accepted. Conclusion : In a nutshell, CPR education for the 4th and 5th graders of elementary schools had an influence on their confidence in practicing CPR and on their knowledge. This study showed that as time passed. the educational effect declined in terms of knowledge point, capability of practicing CPR, and the precision level of CRP skill. The results of the study could be postulated into the fact that re-education within 8 weeks after the first education was essential to retaining the educational effect. Therefore, we need to vitalize the CPR education for elementary school students repeatedly on a regular basis in order to continue the educational effect after they were grown-ups and to make them play their roles as a first aider.

  • Now, safety assurance in construction sites should be accomplished by its own organization rather than control of the code or government. It is believed that the safety assurance can be considerably improved by a lecture or an education using the existing theories or literatures up to now, but it is thought that fundamental safety assurance we not able to be accomplished without developing safety devices '||'&'||' equipment or taking fundamental measures, based on the result analyzed from workers behaviors. There are various behaviors of the workers showed in construction site, but only tests for hammerusing works such as form, re-bar, stone workers directly related to the grip strength are mainly performed, investigated and measured here for the study. The above works are similar to power grip, 7th picture on seven items which are categorized for hand grip types(Ammermin 1956 ; Jones ; Kobrick 1958). Measurements of grip strength are commonly taken in anthropometric surveys. They are easy to administer but unfortunately it is rather dubious whether they yield any data that are of interest to the engineer. Very fewer controls of tools are grasped and squeesed studies showed very little overall correlation between grip strength and other measures of bodily strength (Laubach, Kromer, and Thordsen 1972), but hammer-using work which is practically progressed in construction site are mainly influenced with grip strength. According to the investigation on work measurement, it is shown that 77% of form worker are using hammer to be related to grip strength. In this study, it is particularly noticed that wearing safety gloves in construction site is required for workers safety but 20% difference between grip strength with safety gloves and without ones are commonly neglected in the site(Fig. 1). Nevertheless, safety operation with consideration of the above 20% difference is not considered in the construction site. Factors of age, kinds of work, working time, with or without safety gloves are in vestigated '||'&'||' collected at the sites for this study. Test, not at each working hour but at 14 : 00 when the almost all of the workers think the most tired, resulting from the questionaires, also when it is shown on the research report has been performed and compared for main kinds of works : form '||'&'||' re-bar work. Tests were performed with both left SE rightand of the workers simultaneously in construction site using Rand Dynamometer(Model 78010, Lafayette Instrument Co., Indiana, U.S.A) by reading grip strength on the gauge while they are pulling, and then by interviewing on their ages, works, experiences and etc., directly. The above tests have been performed for the dates of 15th march-26th May '95 with consideration of site condition. And even if various factors of ambient temperature on the testing date, working condition, individual worker's habit and worker's condition of the previous ate are concerned with the study. Those are considered as constants in this study. Samples are formwork 53, rebar 62, electrician 5, plumber 4, welding 1 from D construction Co., Ltd, ; formwork 12, re-bar 5, electrician 2, from S construction Co., Ltd, , formwork 78, re-bar 18, plumber 31, electrician 13, labor 48, plumber 31, plasterer 15, concrete placer 6, water proof worker 3, maisony 5 from B construction Co., Ltd. As In the previously mentioned, main aspect to be investigated in this study will be from '||'&'||' re-bar work because grip strength will be directly applied to these two kinds of works ; form '||'&'||' re-bar work, eventhough there are total 405 samples taken. It is thought that a frequency of accident occurrence will be mainly two work postures "looking up '||'&'||' looking down" to be mainly sorted, but this factor is not clarified in this study because It will be needed a lot of work more. Tests has been done at possible large scale of horizontally work-extended sites within one hour in order to prevent or decrease errors '||'&'||' discrepancies from time lag of the test. Additionally, the statistical package computer program SPSS PC+has been used for the study.

  • The parents have much expectation upon the pregnancy and child birth, and in most cases, they expect the healthy parturient child. However, we can be placed on the high-risk conditions which have the physical, social and immature infant, due to the unexpected results, among the new-born. Accordingly, these high-risk newborn and premature infants will be mostly in NICU, which the concentrated medical treatment can be given, upon their conditions. After their birth and during these periods, they will be divided from the parents, and the nurse will accomplish the bringing-up activities which they can take care of the infant, expected by the parents after their birth. The hospitalization of high-risk newborn including these premature infants is the shocking experience to the parents of family, and thus they can feel the fear and uneasiness, and these reactions of parents are troubled in the behavior at the usual days, and cause the disorder and spiritless status, and these results break the supporting ability of parents, and cause the obstruction. Also, the unavoidable division between the parents and the children as like hospitalization of children can make the parents to feel the alienation emotionally, and this causes the results which the pride on the bringing-up ability of baby gets to be lost. These problems can cause the difficulties on the bonding or the parenting in the further days, and can be related to the neglect and abuse of children. Also, it is gradually increased to study and report which the emotional division by the physical division between the mother and the baby obstructs the normal affection course between the parent and the infant. The stress caused by the birth and the hospitalization of high-risk newborn, as like this, is important in the points which it can uncertainly affect the potential energy for the relationship of parent-child who are finally healthy. Accordingly, the significance and purpose of this study are to understand the contents and degree of stress which the parents of high-risk newborn including the immature child can be experienced from the hospitalization of ICU for their new borns, and thus to offer the basic program to the nursing intervention program for these. The subject of this study is the mother of newborn in NICU of 10 General Hospitals located at the 3one of Pusan, Korea from September 1997 to October 1997, and thus makes the subject of 95 person of parents who agreed to take part in the study and it is descriptive study related to the stress of mother having the newborn in NICU. The method is based on the preceding study related to the stress of mother having the experience of child hospitalization and chronic disease child, and then acquires the advice of specialists group as like 5 nursing professors, and then is amended and supplemented. Total number of questions is 43 items and consists of 5 factors as like medical treatment &nursing procedures, disease status & prognosis, role of parents, communication & inter-personal relationships, hospital environment, and is 5 point Likert Scale. The reliability of this study method is very highly shown to be Cronbach α=0.95. The collected data is analysed as Average, Frequency, Standard Deviation, T-test, ANOVA, Pearson Correlation Coefficient, Duncan multifulrange test by use of SPSS /PC (V7.5). The results of this study is summarized as under. 1. Every characteristics of subject is which the party of mother is 28.70age(±7.48) in the average ages, 51% in the high-school graduate, 38.5% in the christianity, total monthly income is 212.55 thousand won(±1.971), 74.5% in the housewife, 72.9% in the parents and children together living and the number of children to be 1.48person(± 0.6) in average, the recognition on the prognosis of baby is 74.0% in 'Don't know', the relationship with the husband after the hospitalization of babyis 37.3% in 'More Intimate', the relationship with the family of husband to be 48% in 'No-change', and the degree which is consulted with the husband about the baby is 55% in 'very frequently' and the visiting number per week is 4.59(±1.63) in average and the accompanying person in the time of visiting is which the number of husband is 56.3% and thus is the highest. The characteristics of baby is which the age is 21.88days(±16.47) after the birth in average, the sex to be 50 person in the female 52.1% and the order of birth to be 54.2% in the first chid, and the weight in the birth to be 2770gm(±610) and the height in the birth to be 46.26cm(±7.62) in aver age. The medical diagnosis is 37.5% in the premature infant, the career of hospitalization is 96.9% in 'None', and the operation plan is 90.6% in 'None' and the execution of operation is 88% in 'None' and the nursing of incubator is 55.2% in 'Yes', and the method of feeding is 50.5% in 'Oral' and the contents of feeding is 46.9% in the 'Milk'. 2. The total stress degree of subject is almost highly shown to be as 3.36(±0.86). If it is compared upon each cause, 'stress on disease status & prognosis' is highest 3.79(±1.28), and it is in the order of 'stress on medical treatment & nursing procedures' 3.70(±0.93), 'stress on hospital environment' 3.14(±0.86), 'stress on role of parents' 3.18(±0.92) and 'stress on communication & inter personal relationship' 2.62(± 0.77) 3. As the results of checking the notworthiness of stress degree upon each variable of subject, the variable showing the noted difference was the birth weight(γ=-0.16, P=0.04), birth height(γ=-0.23, P=0.03), nursing in the incubator(F=8.93, P=0.04), feed method(F=2.94, P=0.04). That is to say, it is shown which the smaller the birth weight is, the higher the stress degree of mother is noteworthily. Also, the smaller the birth height baby is, the higher the stress of mother is. In the incubator, it os shown which the mother whose baby is nursing in the incubator is higher in the stress degree than other mothers. Upon the feeding method of baby, that is to say, TPNis the highest, and it is shown in the order of NPO, Tube feeding, and P.O. feeding. When we review the above-mentioned results, as the status is serious, it is thought which we include the supporting nursing for coping with the stress of parents in the setting-up od nursing plan for the baby in the NICU.

  • This study was done to investigate the effect of stress on appetite and eating habits, and other health-related behaviors. The subjects of this study consisted of 188 males and 224 females in Ulsan area. The results were as follows: When stressed, 56% (n = 231) of the subjects experienced a change in appetite and of these, 32% (n = 132) experienced an increased appetite. Stress-induced eating may be one factor contributing to the development of obesity. There was a gender-specific response to stress in which women are more likely to use food to deal with stress, whereas men are more likely to use alcohol consumption or smoking. It was found that types of stressors were individual (52.9%), social (50.7%), family relations (34.5%), work demands (34.2%) and physical environment (32.3%). Stress-induced symptoms of the subjects were anxiety (38.3%), headache (36.7%) and neck or shoulder aches (36.2%), and females experienced those symptoms more than males. Those older than 50 years had a higher eating habit score and lower stress score compared with younger subjects. There were significant differences between sex, age, occupation, family type, BMI, exercise, sleeping hours and eating habits or stress level. This study may be helpful in advancing findings in this area to better provide health professionals with appropriate counseling tools to improve the health of all individuals.

  • This study dealt with the comparison of the individual lipid component and fatty acid composition in the six varieties of dent corn, Zea mays Indentata. The fatty acid and sterol compositions of the total lipid were analyzed by gas liquid chromatography. The total lipid was also fractionated into three lipid classes namely neutral, glyco and phospolipid by the methods of silicic acid column chromatography. The lipid componets of lipid-classes were estimated by thin layer chromatography and TLC-scanner. The contents of total lipid in six varieties of Cdent corn were $3.7{\sim}5.3%$. Total lipid were mainly Composed of triglyceride$(69.8{\sim}75.7%)$ free fatty acid$(13.0{\sim}17.9%)$, lanosterol$(4.8{\sim}6.0%)$. hydrocarbon & esterified sterol$(3.5{\sim}6.0%)$, and polar lipid & pigment$(2.7{\sim}5.9%)$. The contents of triglycerde in $Chech'{\breve{o}}nok$ and Hwangok No.3 were slightly higher then other varieties. The major fatty acid In total lipid from six varieties of dent corn were chiefly consisted of linoleic$(46.0{\sim}61.4%)$, oleic$(21.9{\sim}29.9%)$ and palmitic acid$(10.9{\sim}16.7%)$. Particularly the content of linoleic acid in $Chech'{\breve{o}}nok$ was higher but oleic and palmitic acid in $Chech'{\breve{o}}nok$ were less than other varieties. The compositions of 4-desmethylsterol were mainly composed of siterol $(44.0{\sim}63.2%)$, campestetel$(11.6{\sim}15.5%)$ and stigmasterol$(5.6{\sim}9.1%)$. The content of sitosterol in Chinjuok was higher than other varieties and isofucosterol was detected only in Chinjuok. The compositions of 4-monomethlysterol were mainly composed of obtusifoliol$(17.7{\sim}37.6%)$, gramisterol$(15.0{\sim}27.0%)$ and citrostadienol$(9.1{\sim}17.3%)$. The contents of obtusifoliol and citrostadienol in Kwangok and Chinjuok were less than other varieties. The contents of fractionated neural lipid in Suwon No.19. Kwangok, $Hoengs{\breve{o}}ngok$ and Chinjuok$(90.3{\sim}97.1%)$ were higher than those of $Chech'{\breve{o}}nok$ and Hwangok No.3$(85.5{\sim}86.1%)$. Neutral lipid were mainly composed of triglyceride$(24.7{\sim}80.0%)$, lanosterol$(6.2{\sim}20.2%)$, Cholesterol$(1.0{\sim}50.6%)$, free fatty acid$(4.4{\sim}8.9%)$ and esterified sterol$(1.5{\sim}15.9%)$. The major fatty acid in neutral lipid from six varieties of dent corn were chiefly consisted of linoleic$(26.2{\sim}55.4%)$ oleic$(22.7{\sim}39.1%)$ and palmitic acid$(11.4{\sim}41.6%)$. Particularly the contents of linoleic acid Suwon No.19 and $Chech'{\breve{o}}nok$ were higher but palmtic acid in Suwon No.19 and $Chech'{\breve{o}}nok$ were less tan other varieties. Glycolipd were mainly composed of nlonoglycosflsterol $(17.5{\sim}56.4%)$, monoglycosylce-ramide $(8.2{\sim}25.9%)$ and monoglycoslydiacylglycerol$(12.4{\sim}22.2%)$. The contents of mono-g1ycosrlceramide and monoglycosrlsterol in Chinjuok. Were higher than other varieties. The major fatty acid in glycolipid from six varieties of dent corn were chiefly consisted$(14.6{\sim}39.3%)$, palmitic$(20.0{\sim}26.1%)$, linoleic$(3.6{\sim}26.9%)$ and heptadecanoic acid $(3.3{\sim}24.7%)$. Particutarly the cantents of oleic acid in Chinjuok and heptadecanoic acid in $Chech'{\breve{o}}nok$ were higher than other varieties. Phospholipid were mainly composed of phosphatidyllnositol$(30.9{\sim}86.4%)$ and phosphatidylcholine$(4.5{\sim}22.0%)$. The contents of phosphatidrlinositol in $Hoengs{\breve{o}}ngok$ and Hwanngok No. 3 were less than other varieties. The major fatty acid in phospolipid from six varieties of dent corn chiefly consisted of patmitic$(37.2{\sim}61.6%)$ heptadecanoic$(9.2{\sim}31.8%)$ and oleic acid$(4.3{\sim}17.2%)$. Particuiarlr the content of oleic acid in $Hoengs{\breve{o}}ngok$ was higher but heptadccanoic acid in $Hoengs{\breve{o}}ngok$ was less than othcr varieties.
