Most of existing integrated remote controllers can control only a group of home appliances made by the same manufacturer. And they cannot monitor the status of home appliances since they are based on analog RF(Radio Frequency) signal and operate in a uni-directional manner In this paper, we propose a software framework for a hi-directional universal remote controller(URC) which monitors the status of home appliances in Wireless Personal Area Network(WPAN). The URC can handle the control and status messages which consist of a command with related arguments. When a user wants to control any home appliance, the URC can be dynamically configured to its dedicated remote controller by generating a GUI according to its profile. Any other devices which have a capacity for understanding the profile from the controlled devices can play the same role of the URC.

It was known that many beekeepers use some acaricides to protect their bees. Among the acaricides used in bees, amitraz, bromopropylate, coumaphos, and cymiazole were used commonly in Korea. In middle of 2006, Korean government set maximum residual limit (MRL) of amitraz and coumaphos as 0.2 ppm and 0.1 ppm, respectively. Because the environment of bee farm changes every year, it is needed to monitor acaricides in honey continuously. In this work, ten samples of honey collected from local markets and internet in 2011 were tested for determination of the amount of amitraz, bromopropylate, coumaphos and cymiazole by HPLC-DAD. Levels of the acaricide residues found were less than 25 ppb.

Poly(vinyl alcohol) (PVA) and N-(2-hydroxy)propyl-3-trimethylammonium chitosan chloride (HTCC), a water soluble chitosan derivative synthesized by the reaction of quaternary ammonium compound with chitosan, were blended using water as a solvent and the PVA/HTCC blend films with various compositions were prepared by solution casting method. The miscibility between the two polymers and the thermal properties of the blend films were investigated using FT-IR, DSC, DMA, and TGA. Single glass transition temperatures and single melting temperatures of the blend films along with the strong and clear film state for the whole composition of blending ratios suggest the miscibility between PVA and HTCC. The PVA/HTCC blend films with HTCC content of 1% and greater showed excellent antimicrobial activity.

The crosslinked PVA/PAA membranes developed in our laboratory have been characterized for water-isopropyl alcohol mixture in terms of permeabilities and separation factor. When the feed mixture was 12wt% water, the permeability and the separation factor for PVA/PAA=75/25 membrane show $63g/m^{2}h$ and 1520 at $80^{\circ}C$, respectively. In case of 5wt% water in feed mixture, the permeability for PVA/PAA=75/25 membrane is $56g/m^{2}h$ at 8$0^{\circ}C$ while the separation factor is 1563.

Theoretical studies on the electrophilic substitution reactions of five-membered heteroaromatic compounds, furan, pyrrole and thiophene, with isopropyl cation were carried out using the MNDO method. The results indicated that site selectivities of ${\alpha},{\beta}$ and hetero-atoms are not controlled by electrostatic interactions but are determined mainly by charge trasfer stabilization between the HOMO of heteroaromatics and the LUMO of the electrophile. The reactivity order for ${\alpha}\;and\;{\beta}$ positions was pyrrole > furan > thiophene, in agreement with the solution-phase as well as the gas-phase experimental results.

Purpose: The purpose of this study was to identify the lipid profile ratios as factors affecting disease progress in patients with high-grade primary brain cancers undergoing concurrent chemoradiotherapy (CCRT) and adjuvant chemotherapy. Methods: The levels of lipid profile ratios were evaluated by looking at the total cholesterol (TC) to high-density lipoprotein (HDL)-cholesterol (TC/HDL-c), low-density lipoprotein (LDL)-cholesterol to HDL-cholesterol (LDL-c/HDL-c), and triglycerides to HDL-cholesterol (TG/HDL-c). This descriptive research was conducted 7 months after the initiation of CCRT and adjuvant chemotherapy. Results: A total of 36 patients with newly diagnosed primary malignant brain cancer were included in the study. The levels of lipid profile ratios such as TC/HDL-c, LDL-c/HDL-c, TG/HDL-c were significantly different between the patients with and without disease progress at 7 months after initiation of CCRT and adjuvant chemotherapy. Conclusion: The lipid profile ratios were indicators affecting disease prognosis with tumor-related factors at 7 months after initiation of CCRT and adjuvant chemotherapy. Therefore, lipid profile ratios indicating hyperlipidemia in patients with high-grade brain cancers should be carefully monitored during and after cancer-related therapy.

A Texture profile for frozen pizzas was developed and applied to a comparison of the texture of frozen pizzas heated by conventional and microwave ovens. The texture profile consisted of 29 attributes evaluated at the following five stages: visual and manual. lip feel, first bite, mastication, and swallowing. The microwave pizza tended to be more crisp, dry, and rough but less tender than the conventionally heated pizza. Separate evaluations of the center and edge portions showed differences only in top greasiness, wetness of sauce on palate, moisture release for both types of pizza suggesting that the separated evaluations were not necessarily required. The edge tended to be less greasy and moist than the center possibly because it is more susceptible to overcooking and subsequent drying out.

This study examines the image management behavior according to self-monitoring, self-objectification of profile-based SNS users. Questionnaires were administered to 313 SNS users including both men and women in their 20s to 30s. The SPSS 25.0 package was utilized for data analysis, which included frequency analysis, factor analysis, Cronbach's ?, t-test, and regression analysis. The study analyzed self-monitoring in 2 groups (high, low), self-objectification for 2 factors (body surveillance, body shame), and image management behavior for 5 factors (fashion oriented, instrumentality, conformity, ostentation, interpersonal disposition). The results revealed: first, self-monitoring groups exhibited significant differences in self-objectification. The higher self-monitoring group was more influenced by body surveillance and body shame compared to the low self-monitoring group. Second, self-objectification had a positive influence on all the factors of image management behavior. Especially, body surveillance demonstrated a high influence on instrumentality and body shame showed a high influence on ostentation. Third, the self-monitoring groups showed significant differences in all the factors of image management behavior. The higher self-monitoring group demonstrated more influence of image management behavior compared to the low self-monitoring group. These results provide useful information in understanding the influence of social media on users' psychological attitude and consciousness toward their body and image management behavior.

The purpose of this study is to interpret the semantic actions of body image symbolized in body expression images shown by micro-influencers body profiles to understand the body profile phenomenon of the MZ generation. As a result of collecting body profile data from micro-influencers, the body profile image types of female influencers on SNS were classified into four types, Athletic, Slim body, Natural, and, Glamorous. Images representing each type were analyzed using the Roland Barthes' Myth model analysis frame. As a result of the semantic analysis, influencers were found to be very active and bold, emphasizing certain body parts according to the type of body image they pursue. Fashion is strategically used to emphasize these aspects. It was found that the ideology of a 'subjective modern woman' was commonly expressed through emphasis on visual signs. This study is meaningful in that it can indirectly lead to the understanding the fashion culture expressed by the MZ generation and provide consumer information and essential data that can be used for communication strategies in the fashion market.
