Fish sarcoplasmic protein (SP) is currently dumped as waste from surimi industry and its recovery by practical method for being the non-meat ingredient in meat industry would be a strategy to utilize effectively the fish resource. This study was aimed to apply pH treatment for fish SP recovery and evaluated its effect on pork myofibrillar protein (MP) gel. The pH values of fish SP were changed to 3 and 12, and neutralized to pH 7 before lyophilizing the precipitated protein after centrifugation. Acid-treated fish SP (AFSP) showed about 4-fold higher recovery yield than that of alkaline-treated SP and water absorption capacity was also about 1.2-fold greater. Because of the high recovery yield and water absorption capacity, AFSP was selected to incorporate into MP with/without microbial transglutaminase (MTG). The effects of AFSP and MTG on the physicochemical and rheological characteristics of MP and MP gel were evaluated. MTG induced an increase shear stress of the MP mixture and increase the breaking force of MP gels. MP gel lightness was decreased by adding AFSP. MP gel with MTG showed higher cooking loss than that without MTG. A reduction of cooking loss was observed when the AFSP was added along with MTG, where the insoluble particles were found. Therefore, AFSP could be contributed as a water holding agent in meat protein gel.
Purpose: The purpose of this study is to identify the health promoting lifestyle and need assessment of a health promotion program. and to develop a health promotion program for rural elderly. Method: The subjects of the study were 366 adults chosen from 24 villages located in Geochang Gun, Korea. Data sampling used a quota sampling method. Analysis of the data was done by using descriptive statistics, t test, ANOVA and the Scheffe test with SPSS. Results: 1) The average score of performance in the health promoting lifestyle was 1.85. In the subscales, the highest degree of performance was 'nutrition', followed by 'interpersonal relationships', 'health responsibility', 'stress management', 'spiritual growth', and the lowest degree of performance was 'physical activity'. 2) Health promoting lifestyles were significantly correlated with such demographic variables as age (F=2.684, p=.047), education (F=10.989, p=.000), monthly pocket money (F=3.516, p=.008), religion (F=7.160, p=.000), current health status F=3.375, p=.035), health education (t=2.476, p=.014). 3) Health promoting lifestyles were significantly correlated with such life style pattern variables as milk drinking (F=3.767, p=0.035), hobbies (t=3.072, p=0.002), exercise (t=7.186, p=0.000). 4) There is a high level of need for the need assesment of the health promotion program for the elderly in the rural area. Conclusion: With the above findings. I propose that it is necessary to understand a health promoting lifestyle and need assessment for a health promotion program, and to develop a health promotion program considering regional and environmental elements.
Purpose: The purpose of this study was to determine the effects of 5 weeks self-help management program developed by Kim et al. (2000-b) and reinforced with music therapy for post stroke patients. Method: This was pre-experimental study and the subjects were 14 post stroke hemiplegic patients at home who were registered at the Gunsan Health Center. The program was applied for five weeks and two hours for each session composed of the preparation step, the main step and the finishing step. The contents of the program were ROM exercise, daily activity training, risk factors and aftereffects, nutrition management and stress management. To collect data, all subjects were questioned before and after the application of the program. Collected data were analyzed through frequencies, percentages, Wilcoxen signed rank test and Cronbach's alpha using SPSS-WIN program. Result: After the application of the self-help management program, a statistically significant increase was observed in the subjects' ability to perform activities of daily living (p=.039), ability to perform instrumental activities of daily living (p=.005), self-efficacy (p=.001), self-care behavior (p=.001) and quality of life (p=.001), and a statistically significant decrease was observed in depression (p=.012). Conclusion: The present self-help management program was found to be helpful in improving the subjects' physical and psychological functions after they were attacked by stroke, so to be an effective nursing intervention strategy for post stoke patients. Future researches need to reinforce and materialize music therapy and to develop and apply a self-help management program that includes not only post stroke patients but also their families. In addition, it is necessary to expand the scope of subjects and apply follow-up management in order to continue self-help meetings.
This study was designed to explore health promoting lifestyle patterns (HPLP) and self-care activities and identify related variables of patients with rheumatic disease. One hundred fifty rheumatic patients were recruited from two university based rheumatic centers according to selection criteria. Collected data were analyzed using SAS program through which with a structured questionnaire. T-test. ANOVA, and Pearson correlation coefficients were tested. The results were as follows: 1. The mean HPLP score of the subjects was 2.71, showed significant differences with economic condition and educational level. The better economic condition and more educated, showed the higher HPLP score. 2. They showed the highest practices in nutrition(mean score=3.11), and the lowest practices in exercise(mean score = 1.99). 3. The mean self-care activity score of the subjects was 3.36, showed significant differences with economic condition and educational level. The better economic condition and more educated, showed the higher self-care activity score. 4. The HPLP score of the subjects showed positive correlations with self-care activity score(r= .66). Developing health promotion programs focused on exercise and stress management is recommended not only for better health practices of patients with rheumatic disease but also for enhancing their level of well-being and life satisfaction.

In traditional electronic packages the die and the substrate are interconnected with fine wire. Wire bonding technology is limited to bond pads around the peripheral of the die. As the demand for I/O increases, there will be limitations with wire bonding technology. Flip chip technology eliminates the need for wire bonding by redistributing the bond pads over the entire surface of the die. Instead of wires, the die is attached to the substrate utilizing a direct solder connection. Although several steps and processes are eliminated when utilizing flip chip technology, there are several new problems that must be overcome. The main issue is the mismatch in the coefficient of thermal expansion (CTE) of the silicon die and the substrate. This mismatch will cause premature solder Joint failure. This issue can be compensated for by the use of an underfill material between the die and the substrate. Underfill helps to extend the working life of the device by providing environmental protection and structural integrity. Flux residues may interfere with the flow of underfill encapsulants causing gross solder voids and premature failure of the solder connection. Furthermore, flux residues may chemically react with the underfill polymer causing a change in its mechanical and thermal properties. As flip chip packages decrease in size, cleaning becomes more challenging. While package size continues to decrease, the total number of 1/0 continue to increase. As the I/O increases, the array density of the package increases and as the array density increases, the pitch decreases. If the pitch is decreasing, the standoff is also decreasing. This paper will present the keys to successful flip chip cleaning processes. Process parameters such as time, temperature, solvency, and impingement energy required for successful cleaning will be addressed. Flip chip packages will be cleaned and subjected to JEDEC level 3 testing, followed by accelerated stress testing. The devices will then be analyzed using acoustic microscopy and the results and conclusions reported.
The safety of on-going ships is one of important concerns in the view of environment and human life. The ship in bad condition is likely to be subjected to accidental loads such as collision. Once she has one or several minor collision damages in the form of circle or ellipse, her ultimate strength under compression or tension load will be reduced. Here, it is important to evaluate the reduction ratio of ultimate strength due to the damage from safety point of view. The problem of strength reduction of a plate with cutout such as opening hole has been treated by many researchers. As a result, a closed-form formula on the reduction of ultimate strength of a plate considering the effect of several forms of cutout was suggested. However, the structure of ships is composed of a plate and a stiffener so-called a stiffened plate, and it is likely to be damaged at a plate and stiffeners together in collision. This paper is to investigate the effect of minor collision damage on ultimate strength of a stiffened plate by using numerical analysis. For this study, the shape of minor collision damage of a stiffened plate was made by using contact algorithm. The deformed shape was used as an initial shape for ultimate stress analysis. Then, a series of nonlinear FE analysis was conducted to investigate the reduction effects of ultimate strength of the stiffened plate. The boundary condition was applied as simply supported at all boundaries, and the tripping of stiffener among failure mode under compression loading was neglected. These results were settled in the form of reduction ratio between ultimate of original intact stiffened plate and that of damaged stiffened plate.
The usage of nitrous oxide is increased for the anxious patient to dental treatment. There are two methods to induce the sedation during dental treatment. One is sedation with drugs the other no need of drugs. We discussed here about sedation with drugs. The methods of drug administration are oral, intramuscular, intravenous, inhalation. The method of oral administration of drugs are convenient to patient and doctor but poor controllability. Intramuscular method is a parenteral technique that maintains several advantages over the enteral technique. However its pales in comparison to other parenteral technique. Intravenous method represents most effective method of ensuring predictable and adequate sedation in all patients. But it has inability to reverse the action of drugs after they have been injected except some drugs (e.g., narcotics and benzodiazepine). A variety of gaseous agents may be administered by inhalation to produce sedation. In dental practice, the inhalation administration of gas means use of nitrous oxide. There are many advantages of nitrous oxide administration. First, very short latent period and rapid onset of drug action which lead to possible titration of drug concentration. With nitrous oxide, clinical effects may become noticeable as quickly as 15 to 30 seconds after inhalation. Recovery from inhalation sedation is also quite rapid. In out patient dental practice rapid recovery is very important because it permit to discharge the patient without escort and the patient return to their ordinary life without limit. To success the conscious sedation with nitrous oxide, the administrator should be keep the mind that always titration of nitrous oxide concentration during induction and treatment. Careful observation need during treatment to prevent oversedation because the adequate nitrous oxide concentration to patients changed by environmental stress. Always begins with 100% oxygen and ends with 100% oxygen to prevent diffusion hypoxia which rare in clinical practice.
Three-week old Commelina communis was transferred and grown in Hoagland solution containing $100{\mu}M\;Cd^{2+},\;100{\mu}M\;Cd^{2+}+100{\mu}M\;kinetin,\;100{\mu}M\;Cd^{2+}+100{\mu}M\;zeatin\;and\;100{\mu}M\;Cd^{2+},\;200{\mu}M$ zeatin for 7 days, and then a number of physiological activities were investigated. In control, the length of the stem of plants was increased to 4.7cm, but in $Cd^{2+},\;Cd^{2+}+kinetin,\; Cd^{2+}+100{\mu}M\;zeatin\;and\;Cd^{2+}+200{\mu}M$ zeatin treatments, the growth of plants were increased to 1.5cm, 2.1cm, 3.9cm and 4.3 em, respectively. In the treatments of $Cd^{2+},\;Cd^{2+}+kinetin,\;Cd^{2+}+100{\mu}M\;zeatin\;and\; Cd^{2+}+200{\mu}M$ zeatin, total chlorophyll contents were reduced to $26\%,\;24\%,\;15\%\;and\;3\%$, respectively, on the contrast to the control. In chlorophyll fluorescence experiments, Fv/Fm ratios were also reduced to $44\%,\;21\%,\;17\%\;and\;5\%$ in the light intensity of $2100{\mu}Mmole\;E\;m^{-2}s^{-1}\;by\;Cd^{2+},\;Cd^{2+}+kinetin,\;Cd^{2+}+$100{\mu}M\;zeatin\;and\;Cd^{2+}+200{\mu}M$ zeatin treatments on the contrast to the control. Water stresses were increased to 2.6, 1.7 and 1.2 times by $Cd^{2+},\; Cd^{2+}+kinetin\;and\;Cd^{2+}+{\mu}M$ zeatin. On the other hand, combination of $Cd^{2+}+200{\mu}M$ zeatin reduced water stress to $0.12\%$. In $Cd^{2+}$ accumulation experiments $Cd^{2+}$transports were inhibited to $33\%\; 48\%\;and\;70\%\;by\;Cd^{2+}+kinetin,\;Cd^{2+}+100{\mu}M\;zeatin\;and\;Cd^{2+}+200{\mu}M$ zeatin. Therefore, it could be concluded that zeatin clearly reduced the toxicities of $Cd^{2+}$ by reducing the absorption of $Cd^{2+}$.
The objective of the present study is to investigate healing design attributes for adolescent patients and to identify the relationship among healing design attributes and the meaning of home. This study examined the environmental preferences of American adolescents for hospital rooms to investigate age-appropriate healing design attributes. The health-related quality of life (HRQOL) concept was adapted to this study as a theoretical framework. One hundred six American adolescents participated in the survey. Participant adolescents consisted of two groups by their health status: forty-seven adolescent patients who were waiting for their surgical operations in waiting rooms and fifty-nine healthy high school students while they were at school. Participants aged in range from 14-year to 18-year olds with a mean of 16-year olds. Data collection consisted of two different instruments: Emotional state survey with demographics and environmental preference survey. Environmental values that are important to adolescents were control of privacy, having outside view, and quiet places to go. However, staying in a single-bed room for hospitalization is ranked the lowest score for the participating adolescents. Adolescents who perceived higher stress level preferred to have quiet places to go, to control over privacy and to have outside view significantly. The study resulted that the most important design attribute for American Adolescents was "privacy control", which is the essence of the meaning of home. There are some significant discrepancies in environmental preferences of hospital rooms by different genders and different health status.
Objectives: This study aims to identify the influencing factors of using postnatal care among illiteracy women who live in the Democratic Republic of Congo. Methods: Household survey was done from February 1 to 8, 2013 in the Kwango district of Democratic Republic of Congo, and 400 childbearing women who has under 5 years old children and pregnant women was randomly selected and answered through the interview with a questionnaire. For analysis the data, ${\chi}^2$ test and logistic regression analysis were used. Results: Woman who can read, write and mathematical calculation was 195 (47.4%) of total 411 answers and 161 (39.2%) used postnatal care for their latest pregnancy. Age at first marriage (${\chi}^2=18.481$, p<.001), religions (${\chi}^2=11.165$, p=.011), languages (${\chi}^2=35.586$, p<.001), the experience of children death (${\chi}^2=16.507$, p<.001), antenatal care over 4 times (${\chi}^2=15.315$, p<.001), postnatal care (${\chi}^2=15.558$, p<.001) is significantly different from literacy level. Among illiterate women group, who are protestant (OR=.330), using Lingala (OR=.128), took elementary education (OR=.223) and farmer (OR=.040), used less postnatal care. Conclusions: For increasing usage of postnatal care among illiterate women, new approach method should be considered such as a visual communication method and a community health workers' training program for giving an outreach service to pregnant women care.
