Purpose: Preterm infants frequently require red blood cell (RBC) transfusions in neonatal intensive care units (NICU). Storage RBCs undergo many changes during storage periods. We aimed to compare the hemoglobin (Hb) correction effect according to the period of RBC storage and investigate the factors influencing Hb correction. Methods: This retrospective study reviewed the medical records of 289 patients who received RBC transfusion more than once in the NICU of Kosin University Gospel Hospital between February 2006 and March 2016. The subjects were classified into two storage groups: short-term (${\leq}7days$, n=88) and long-term (>7 days, n=201), according to the period of RBC storage. We checked Hb levels by complete blood cell count tests conducted within 2 days before and 5 to 9 days after the first transfusion. We compared the Hb difference between the two groups and analyzed the factors influencing Hb correction. Results: Excluding the use of an invasive ventilator, there was no significant difference between the two groups in terms of clinical characteristics. There was no significant difference in the Hb correction effect between the two groups (P=0.537). Birth weight greater than 1,500 g, higher weight at transfusion, and larger volume of transfusion were significant prognostic factors affecting greater changes in Hb. In addition, surgery experience, higher Hb level at transfusion, and additional blood tests were found to be significantly associated with less changes in Hb. Conclusion: The RBC storage period did not affect the Hb correction effect. The Hb correction effect may be diminished in infants with lower birth weight and lower weight at transfusion under unstable clinical conditions.

This study was conducted to investigate the effect of relationship and service marketing on the brand interest and behaviors among Korean and Chinese active senior consumers and whether this effect differed between the two groups. A survey was conducted by having participants complete questionnaires administered by a research firm. For empirical analysis, frequency, EFA, CFA, SEM, the metric invariance test, and multiple-group comparison analysis were performed. The analysis results revealed that relationship marketing positively affected both brand interest and consumer behavior. Although service marketing positively affected brand interest, it did not have a significant effect on consumer behavior. In other words, brand interest positively affected consumer behavior through relationship and service marketing. Multiple-group comparison analysis demonstrated that no difference existed between Korean and Chinese active consumers in terms of how relationship marketing affected their brand interest, but a difference existed in how it affected their behavior. Service marketing had a greater influence on Chinese active senior consumers' brand interest than on Korean active senior consumers. However no difference existed between the two groups with respect to how service marketing affected their behaviors. Finally, brand interest had a positive effect only on Korean active senior consumers' behavior through relationship and service marketing, but not on Chinese active senior consumers. In conclusion, relationship and service marketing should be used to enhance the brand interest among Korean active senior consumers, and business activities should be planned by building relationships with Chinese active senior consumers to affect their behavior.

Recently, as interest in appearance has increased, various studies on treatment method for short stature are being conducted. In this study, the effect of growth plate stimulation on the height growth of children and adolescents was studied. As a result of pre- and post-analysis of the experimental group, it was confirmed that the difference in average height according to growth plate stimulation was relatively large. In addition, in the results of analyzing the effects of demographic factors on the height growth of the experimental group and the control group, weight showed the greatest influence on height growth among the demographic factors affecting the height growth of the experimental group. The effect on the height growth of the control group was found to have an effect in the order of age, weight, and father's height. The difference in height changed post-mortem between the experimental group and the control group was 1.10 cm for 3 months, and the difference was the result of growth plate stimulation. It was confirmed that growth plate stimulation had a significant effect on the height change of children and adolescents, except for weight, which is a common factor of height change in the experimental and control groups. Therefore, it is expected that it can be used as a treatment method for short stature.

Purpose: To examine the effectiveness of various treatments; bifocal spectacles, orthokeratology, atropine, and time spent in outdoors; in slowing down the myopia progression for Asian adolescents (6-18age). Methods: The research focused on examining the most effective treatment in controlling myopia based on the literature sources that have been published. Through meta-analysis of various research papers that already has been done in this field, a lot of data was collected. For each treatment, the difference in axial length and spherical equivalent over time was measured and recorded. To quantitatively record the difference, both axial length and spherical equivalent was determined by value of control group value of treatment group. The paper compared the effectiveness of each treatment based on the data that was measured. Results: Adolescents who chose to spend time outdoors in order to slow down myopia progression had axial length difference of 0.03 mm and spherical equivalent difference of 0.17 D. Adolescents that used atropine had axial length difference of 0.36 mm and spherical equivalent difference of 0.92 D. Bifocal spectacle resulted in axial length difference of 0.21 mm and spherical equivalent difference of 0.59 D, and for orthokeratology 0.23 mm and 0.04 D, respectively. Axial length wise, myopia was most controlled by the atropine since there was a greatest difference between the group that got the treatment and the group that did not have the treatment. According to the spherical equivalent difference data, myopia was most controlled by atropine. Conclusion: Atropine showed the most effective result in controlling myopia among the four treatment. Again, compared to other three treatment, using atropine appeared to have greatest ability in slowing down myopia progression since adolescents who were treated with atropine had greatest difference from adolescents in the control group that had the same condition but didn't get the treatment. However, every treatment was only used for 2 or 3 years which is quite short time period to measure the long term effect of the four treatments. Also, since atropine is a pharmaceutical method to control myopia, it may harm adolescents' eyes compared to optical or environmental treatment.

A high-rise residential building experienced stack effect problems during the winter such as difficulties in opening residential entrance doors and whistling noise from elevator doors generated by airflow. Field measurements were carried out on the building and the problems were verified by the analysis of the measurement results from three points of view: the total stack pressure difference, pressure distribution on each floor, and the location of the neutral pressure level. Based on the analysis of the three key parameters, possible solutions were proposed, such as zoning vertical shafts, lessening the airflow from the entrance doors on basement floors and lobby floor by installing vestibules, improving the airtightness of exterior walls, and installing separation doors where the problems occur. Simulations of proposed solutions were conducted and the effects of reducing the pressure difference were evaluated. Stack effect problems in a high-rise residential building were verified through field measurements and could be mitigated by the solutions which were drawn from the analysis of the field measurements and the simulation results.

Purpose: The purpose of this study was to confirm the immediate effect of wrist joint mobilization with taping on the range of motion, grip strength, and spasticity. Methods: Thirty stroke patients were randomly divided into two groups: the joint mobilization with taping group (n=15) and a taping group (n=15). For measurement of spasticity and joint range of motion, the modified Tardieu scale, active and passive range of motion of wrist flexion, as well as extension were measured by the Rapael smart glove, and for grip strength measurement, grip dynamometer was performed. Results: The experimental group showed a significant improvement in the range of motion, grip strength, and spasticity after 10 minutes of taping (p<0.05), no significant difference was found in the control group (p>0.05). However, there was no significant difference between the two groups (p>0.05). Conclusion: The study found that wrist joint mobilization with taping has an immediate effect on wrist range of motion, grip strength, and spasticity in stroke patients, whereas it was not effective in the control group with just taping. The long-term change still needs to be evaluated, when taking into consideration of the carryover effect.

This experiment was undertaken to study effect of fall Fertitizarion on spring regrowth of Korean lawngrass( Zoysia japonica Steud ) Results obtained are summarized as follows : 1. late fall fertilization stimulated the spring regrowth of Korean lawngrass. hut early spring application showed little effect on that 2. The yield of clippings on May 21 was obviously greater in late fertilization plots(treatment C, D and E) than other plots(treatment A, B and control, but there was no significant difference in clipping yields of C, D and F treatment. 3. Both nitrogen and reducing sugar contents of runner fell down in spring. It was suggested thatthese constituents be translocated from runner to other parts during the budding period. 4. The nitrogen content of runner was obviously mote in the plot of late fall fertilization. In contrast to nitrogen, no obvious difference was found in reducing sugar content of runner of seven application date. It was suggested that the roots of plant be still able to absorb to absorb nitrogen under dormancy. .5.From these results. late fall fertilization enhances the development of Korean lawngrass in the following spring. But early spring application shows little effect on spring regrowth.

This study was carried out to evaluate the effects on elementary school children of Internet-based nutrition education programs. The subjects consisted of 80 boys and girls (book-loaming group : 42, Internet-based teaming group : 38) in the 5th grade of elementary school. The results were as follows : The evaluation of Internet-based education programs by Internet-teaming group showed above average in all domains. As the favorite and wholesome menu chose‘nutrition kingdom’(52.6%) made of animation. The educational effect of this program was evaluated by comparing the methods of the Internet-learning group with those of the book-learning group. For effect-evaluation were measured the degree of nutrition knowledge and diversity score of dietary intake from before and after education. Before undertaking the program, there was no significant difference between the two groups in terms of their nutrition knowledge. However, the nutrition knowledge of the Internet-based teaming group after the program had increased significantly (p < 0.01) compared to the book-learning group. There was no significant difference between the two groups in terms of the diversity of dietary intake before the start of the program, but upon its completion, the Internet-based learning group showed a significant increase compared to the book-loaming group (p < 0.05). This suggests that Internet-based educational programs could be effective in drawing the interest and boosting the concentration levels of schoolchildren. In conclusion, Internet-based nutrition education shows the potential to be an effective alternative education method. (Korean J Nutrition 36(5): 500∼507, 2003)
