  • Multiple temporal scale can be a useful method to understand population dynamics in ecosystem. The multi-temporal scale approach for population dynamics has rarely been researched till lately. This study was carried out to identify the factors in affecting the population dynamics of herons, including Eastern Cattle Egret (Bubulcus coromadus), Grey Heron (Ardea cinerea), Great Egret (A. alba), Intermediate Egret (Egretta intermedia) and Little Egret (E. garzetta), at rice paddy fields of Seokmun-myeon in the city of Dangjin, South Chungcheong Province during the main breeding periods from 2014 to 2017. We identified the population dynamics of herons at different time interval (day and month) using the unmanned monitoring system. As a result, monthly population dynamics was mostly affected by time, mean temperature and mean precipitation, whereas daily population dynamics was affected by mean temperature and habitat types. The results suggest that there are differences in the factors affecting the population dynamics of herons according to the time scale.

  • The Russian icon and Korean tangwha (幀畵, altar portrait of Buddha) are based on the similarity of the divine Being. Each has the characteristic index that forms an existential connection with the object and at the same time, implies the symbolic meaning of the scriptures and doctrines of the Russian Orthodox and Buddhists. Russian icon and Korean tangwha with these attributes have origins in the Byzantine, India and China. Unlike most religious art, Russian icon and Korean tangwha clearly reveal profane orientation and mystical elements. This artistic phenomenon has evolved from the mystical religious culture in Russia and tantric rituals of the early Joseon period. Iconostasis, created from historical figures of the Old Testament, Jesus, the New Testament represent the principles of the macrocosm. Each icon of iconostasis has integrity, while each floor has another narrative and a meta-discourse on the entire composition. Three-Platforms of amrtakundalin can also have a huge epic that is directed from the Low-Platform to the High-Platform for the purpose of salvation. While the narrative of iconostasis has a time structure, from the beginning of the universe up to date in chronological time, amrtakundalin have pictorial transitions of time and space that rises from this life to a heavenly world. Despite the different world views of the Russian Orthodox and Buddhists, iconographical format and symbolism of heaven and hell in the Iconostasis, Last Judgment and amrtakundalin are similar. There is a constant antagonism between heaven and hell, light and darkness, water and flame. Iconographical contents include the water of life and nectar, the book of life and 'eoppu', and the scales and mirror of Karma that discriminate between the good and evil before judgment. The dualistic coordinate concept such as light and darkness, life and death, or heaven and hell that appears in the narrative structure of iconostasis, the Last Judgment and amrtakundalin leads the people to spiritual awakening.

  • The purpose of this study is to define the effects of the roles played by the Doulas : one group educated on the conventional Lamaze method known to have effects on birth pang during delivery process and the other group educated both on Lamaze and therapeutic touch. On the various factors of delivery, and thereby, provide for some basic data to develop an effective nursing intervention to relieve women of their birth pang. 136 mothers who were hospitalized in a general hospital from June 13, 1998 to May 13, 1998 to May 13, 1999 to deliver their first babies were sampled to be divided into control group, test group I and test group II and thus be subject to interviews and observations. As for the tool of study, melzack's(1975) 'pain scale', McCaffery's(1972) and Mcrachlan's(1974) 'pain expression scales' and Spielberger's (1975) 'anxiety scale' were used. The preparatory educational programs consisted of 5week Lamaze method and therapeutic touch. The research, design was quasi-experimental, non equivalent, posttest only control group design. The collected data were processed using the SPSS/PC statistics software for frequencies, means and one-way Anova as well as Tukey HSD and Scheffe test as post hoc for individual comparison. Moreover, chi-square test was used to test the differences between groups, while Pearson's correlation coefficients were analyzed to determine the correlations between anxiety and variables. The findings are as follows ; 1. The birth pain of the mothers delivering first babies scored in a subjective and objective pain scale; 1) There was a significant difference of subjective birth pain at 8~10cm opening of cervix between control group and two test groups. 2) There was no significant difference of objective birth pain as per opening of cervex among three groups in terms of sweating, facial movement, bodily posture and vocal changes. 2. There was no significant difference of trait anxiety among three groups. however, there was a significant difference of state anxiety during labor process between control group and two test groups. On the other hand, all the three groups showed a significantly lower level of anxiety during labor process than when they were carried to the hospital. 3. There was a significant difference of the time of total and first-stage labor among three groups, while there was a significant but small difference of the time elapsed from 8~10cm cervix open to the full among three groups. 4. Two test groups showed a higher frequency of natural deliveries than the control group. 5. Two test groups were subject to these drugs than the control group. In conclusion, it was found that the test group I and II showed a shorter delivery time than the control group, a higher frequency of natural delivery and a lesser use of anodyne or epidural. In particular, this study is significant to develop a nursing intervention service or a therapeutic touch which the nursing administrators can apply to their hospitals in marketing programs.

  • The main objective of this study is to estimate of the vegetation response induced by climate change to soil moisture. We investigated a relationship between vegetation activity and climate variables using Moderate Resolution Imaging Spectroradiometer (MODIS)-retrieved Normalized Difference Vegetation Index (NDVI) and soil moisture. NDVI which extracted from MODIS 13 Vegetation Indices Product was considered as an useful parameter to figure out a relationship with two types of soil moisture, which were observed at Rural Development Administration sites and estimated from Advanced Microwave Scanning Radiometer E (AMSR-E) satellite imagery. The correlation of MODIS-NDVI and ground measured soil moisture were observed, became much stronger when compared to soil moisture values with time lag (5days, 10days, 15days). The correlation patterns between NDVI and soil moisture with different time lag were related to soil texture. The results from this study will be useful to understand the role of vegetation in water balance control in various scales from regional to global climate change.

  • Small angle light scattering (SALS) and field emission scanning electron microscope (FE-SEM) have been used to investigate the light scattering patterns with time evolved during water vapor quenching (relative humidity of 53 (${\pm}3)%$ at $26^{\circ}C$ of polysulfone (PSf)/NMP/Alcohol and chlorinated poly(vinyl chloride) (CPVC)/THF/Alcohol, respective1y. Time dependence of the position of the light scattering maximum was observed at PSf dope solutions, confirming spinodal decomposition (SD), while CPVC dope solutions showed a decreased scattered light intensity with an increased q-value, indicating nucleation & growth (NG). For the each system, domain growth rate in the intermediate and late stage of phase separation decreased with increasing the number of carbon of alcohol used as additive (non-solvent). Also, in the early stage for SD, the scattering intensity with time was in accordance with Cahn's linear theory of spinodal decomposition, regardless of types of non-solvent additive. Also, the size scales obtained by SALS were mutually compared to domain sizes gained by FE-SEM measurement. These observations of scattering pattern were much clearly observed for the 20PSf/70NMP/10n-butanol (w/w%) and agreed with the theoretical predictions for scattering patterns of each stage like the early, the intermediate, and the late stage of SD type phase separation. As the scattering maximum was observed at the larger angles (larger q) in the order of n-butanol > n-propanol > methanol > no alcohol, the pore size of final morphology decreased.

  • An act of children's welfare was made in 1961 for the first time in Korea but it had been nothing but the name in view of practical impact to prevention of child abuse. Real undertakings of Child Abuse Prevention were commenced overtly since 2000 in Korea, when the law for children's welfare was revised to put protective settings for the victims and to establish criterion for children's safety. The history of Child Abuse Prevention is very short in Korea but the reporting cases increased very fast from 4,133 cases in 2001 up to 9,570 cases in 2008 with the enthusiastic activities from people of the associated organizations along with the national supports. But the portion reported by the mandated reporters such as teachers or doctors is still low compared to those of the developed countries. The National Child Protection Agency (NCPA) was founded in 2001 by the Ministry of Health and Welfare to prevent child abuse and to aid recovery of abused and neglected children including their families, through the cooperation of related organizations. NCPA refers reported cases of child abuse to appropriate local centers, operates a computer database system for case management, publicizes national reports of child abuse on a yearly basis and technically supports the Local Child Protection Agency (LCPA) by developing scales for assessment of child abuse and neglect and distributing programs for the education of mandatory reporters. LCPAs operate 24-hour telephone hotline, investigate and visit homes and provide in home services networking with local resources, and operate multidisciplinary teams for screening child abuse victims and supervising case management through multimodal systems. We summarized the present state of child abuse in Korea and reviewed the operating systems for child protection in this country. Through this article, we hope that medical peoples are to be informed on the seriousness of child abuse and to be able to devote themselves for the prevention of child abuse.

  • Efficient hardware implementation of address lookup is one of the most important design issues of internet routers. Address lookup significantly impacts router performance since routers need to process tens-to-hundred millions of packets per second in real time. In this paper, we propose a practical IP address lookup structure based on the binary tree of prefixes of different lengths. The proposed structure produces multiple balanced trees, and hence it solve the issues due to the unbalanced binary prefix tree of the existing scheme. The proposed structure is implemented using pipelined binary search combined with a small size TCAM. Performance evaluation results show that the proposed architecture requires a 2000-entry TCAM and total 245 kbyte SRAMs to store about 30,000 prefix samples from MAE-WEST router, and an address lookup is achieved by a single memory access. The proposed scheme scales very well with both of large databases and longer addresses as in IPv6.

  • Objectives: The objective of this study was to evaluate the thermic effects, the macronutrient oxidation rates and the satiety of medium-chain triglycerides (MCT). Methods: The thermic effects of two meals containing MCT or long-chain triglycerides (LCT) were compared in ten healthy men (mean age $24.4{\pm}2.9years$). Energy content of the meal was 30% of resting metabolic rate of each subject. Metabolic rate and macronutrient oxidation rate were measured before the meals and for 6 hours after the meals by indirect calorimetry. Satiety was estimated by using visual analogue scales (VAS) at 8 times (before the meal and for 6 hours after meal). Results: Total thermic effect of MCT meal (42.8 kcal, 8.0% of energy intake) was significantly higher than that (26.8 kcal, 5.1% of energy intake) of the LCT meal. Mean postprandial oxygen consumption was also significantly different between the two types of meals (MCT meal: $0.29{\pm}0.35L/min$, LCT meal: $0.28{\pm}0.27L/min$). There were no significant differences in total postprandial carbohydrate and fat oxidation rates between the two meals. However, from 30 to 120 minutes after consumption of meals, the fat oxidation rate of MCT meal was significantly higher than that of the LCT meal. Comparison of satiety values (hunger, fullness and appetite) between the two meals showed that MCT meal maintained satiety for a longer time than the LCT meal. Conclusions: This study showed the possibility that long-term substitution of MCT for LCT would produce weight loss if energy intake remained constant.

  • This paper proposes a practical compensation method by using digital signal processing over the creep error which is representative in strain gauge loadcell. The signal compensation method carry out the simulation by deciding compensation constant (time constant) and coefficient measuring the loadcell output response. Then, compensation constant and coefficient are stored on the microprocessor. By using calculated on microprocessor creep error compensation values, weighting value is showed as a digital signal by reducing error values measured through output signals of loadcell. In addition, we apply error compensation method in order to have a dedicated software for loadcell electronic scale. This technique is useful because it has great influence on error rate reduction that has been produced by conventional electronic scales (0.03%). As a result our technique gives better accuracy (0.01%~0.003%) as what is given by digital electronic scale, while it has less complex operation processing.

  • This study aimed to see if as companion animals living with human beings, dogs could provide emotional stability or play a therapeutic role for human beings. Of 12 middle school boys as victims of school violence, 6 were assigned to the experimental group that was provided with an animal-assisted therapy program over a total of 12 sections, one section per week, 60 minutes per section, between September and November 2011, followed by post-test 1 and, one month later, post-test 2. In the experimental composition, the remaining 6 boys were assigned to the comparison group that was allowed to read freely. Analysis was performed by using the scales of depression and self-esteem, and the results showed that the experimental group provided with the animal-assisted therapy program generated more significant therapeutic effects than the comparison group. The therapeutic effects were found to persist one month after the completion of the program. Therefore, it is believed that sensitive adolescents who suffer from depression or have lost self-esteem because of school violence can significantly benefit from an animal-assisted therapy program by reducing the recovery time or by getting lots of help with emotional stability. Further research on the basis of this study is expected to help adolescents with emotional therapy in other areas.
