To determine which are the culturally specific factors of Korean bereavement, this chapter focuses on the view of death and the traditional mourning process which reflect Korean values and norms. The formation of the Korean view and understanding of death has been strongly influenced by three of its major traditional religions: Shamanism, Buddhism, and Confucianism (Park:1994: Hao:1999) and Christianity more recently. Each religion has a different view of death and the appropriate expression of mourning. Korea accommodates funeral customs and rules strictly as a cultural system and has retained these traditions over a long period; hence, some of the traditional funeral rituals still remain in modern Korean life, although some of the rites have been simplified. We have looked at the various ways in which grief and mourning is displayed and shared in a collective manner over a long period of time. This fits in well within the other Eastern cultures that are collectively organized, and contrary to the Eurocentric models do not hastily seek to detach the living from the dead and recognize that grief is a long process, and different individuals may take different amounts of time to recover from the grief. The view of death and bereavement in Korea has sprung from the roots of three Korean religions, together with the recent addition of Christianity, although they mainly result from the three earlier religions. The beliefs of these religions are still closely linked together in the rituals of Korean bereavement on both conscious and unconscious levels. The influence of these religions is evident in practice through the bereaved family's mourning reactions, funeral rites and customs and its views about death. Korea used to have a period of mourning for three years, following traditional mourning rites; then the chief mourner and the bereaved families could return to their normal life. In spite of this long mourning process for the bereaved family, once the funeral ceremony is finished, people expect the bereaved family not to express their grief in public; even the bereaved family does not like to talk about death. The process for bereaved people is related to mourning processes in terms of detachment from the deceased in order to start a new life. Relatives and the community recommend the performance of the kut ceremony for relieving the grief of the bereaved. When one family member dies in an unlucky way, the bereaved family may have some fear or other psychological reactions of grief such as pain, depression, insomnia and nightmares, hallucinations or other physical reactions. Unlucky deaths give the bereaved a very painful time and these types of reactions are often more serious than reactions to natural death. But through the kut ceremony, the bereaved family can start to make a new relationship with the deceased. The taboo of this type of death and death generally remains a crucial aspect of the isolation that bereaved people might face and the collective nature of mourning(even where it is still present) is unable to address this aspect of the privatization of grief.

This paper proposes a search method that explores parameters C and σ values of support vector machines (SVM) to improve performance while maintaining search accuracy. A traditional grid search method requires tremendous computational times because it searches all available combinations of C and σ values to find optimal combinations which provide the best performance of SVM. To address this issue, this paper proposes a deep search method that reduces computational time. In the first stage, it divides C-σ- accurate metrics into four regions, searches a median value of each region, and then selects a point of the highest accurate value as a start point. In the second stage, the selected start points are re-divided into four regions, and then the highest accurate point is assigned as a new search point. In the third stage, after eight points near the search point. are explored and the highest accurate value is assigned as a new search point, corresponding points are divided into four parts and it calculates an accurate value. In the last stage, it is continued until an accurate metric value is the highest compared to the neighborhood point values. If it is not satisfied, it is repeated from the second stage with the input level value. Experimental results using normal and defect bearings show that the proposed deep search algorithm outperforms the conventional algorithms in terms of performance and search time.

The alteration in the pharmacokinetic behaviors of organic cations (OCs) in rats during acute inflammation (AI) was investigated. AI was induced by an intraperitoneal injection of lipopolysaccharide (LPS, 5 mg/kg) 24 hr prior to the start of pharmacokinetic studies. Tributylmethylammonium (TBuMA) was selected as a model OC since it is largely excreted into bile, and is neither metabolized nor binds to proteins in the body. When TBuMA was administered intravenously to AI rats at a dose of 6.6 $\mu$mole/kg, the AUC was increased, while biliary excretion (i.e., cumulative amount and apparent clearance) was decreased compared to normal rats. When TBuMA was administered intravenously to AI rats at a constant rate (i.e., a bolus injection at a dose of 1.5 $\mu$mole/kg followed by a constant infusion at a rate of 1.5 $\mu$mole/kg/hr for 165 min), steady-state concentrations of plasma and liver concentrations of TBuMA were increased significantly, while in vivo hepatic uptake (amount) and canalicular excretion (clearance) were decreased. These results are consistent with a hypothesis in which both the sinusoidal uptake of TBuMA into hepatocytes via the OCT1 and the canalicular excretion of the compound from hepatocytes via the P-gp are decreased by LPS-induced AI.

The synergistic activation mediator (SAM) system can robustly activate endogenous gene expression by a single-guide RNA. This transcriptional modulation has been shown to enhance gene promoter activity and leads to epigenetic changes. Human $interferon-{\gamma}$ is a common natural glycoprotein involved in antiviral effects and inhibition of cancer cell growth. Large quantities of high-purity $interferon-{\gamma}$ are important for medical research and clinical therapy. To investigate the possibility of employing the SAM system to enhance endogenous human $interferon-{\gamma}$ with normal function in innate immunity, we designed 10 single-guide RNAs that target 200 bp upstream of the transcription start sites of the $interferon-{\gamma}$ genome, which could significantly activate the $interferon-{\gamma}$ promoter reporter. We confirmed that the system can effectively and highly activate $interferon-{\gamma}$ expression in several humanized cell lines. Moreover, we found that the $interferon-{\gamma}$ induced by the SAM system could inhibit tumorigenesis. Taken together, our results reveal that the SAM system can modulate epigenetic traits of non-immune cells through activating $interferon-{\gamma}$ expression and triggering JAK-STAT signaling pathways. Thus, this strategy could offer a novel approach to inhibit tumorigenesis without using exogenous $interferon-{\gamma}$.

OTP(One time password) is widely used as an authentication method for financial and other security-sensitive transactions. OTP provides strong security since each password is used only one time while normal password-based authentications use passwords as long term secrets. However, OTP-based authentications relatively lack usability since they require users to hold an OTP card or generator. To overcome such a problem, smartphones start replacing OTP cards and such a method is called smart OTP. However, smart OTP inherits security vulnerabilities that smartphones have. In this paper, we propose a smart OTP authentication based on an extremely light authentication protocol called HB+. HB+ protocol is developed for low-cost devices and has small communication and computation costs. We present our solution and discuss its security, efficiency and practicality. Our contribution is providing a method to securely use smart OTP without losing its efficiency and usability.

In this paper, we propose an optimizing feature extraction method for multiclass problems assuming normal distributions. Initially, We start with an arbitrary feature vector Assuming that the feature vector is used for classification, we compute the classification error Then we move the feature vector slightly in the direction so that classification error decreases most rapidly This can be done by taking gradient We propose two search methods, sequential search and global search In the sequential search, an additional feature vector is selected so that it provides the best accuracy along with the already chosen feature vectors In the global search, we are not constrained to use the chosen feature vectors Experimental results show that the proposed algorithm provides a favorable performance.

Conductive rubber material was molded in a belt shape to measure respiration. Its resistivity was approximately $0.03{\;}{\Omega}m$ and the resistance-displacement relationship showed a negative exponent. The temperature coefficient was approximately $0.006{\;}k{\Omega}/^{\circ}C$ negligible when practically applied on the abdomen. The conductive rubber belt was applied on a normal male's abdomen with the dimensional change measured during resting breathing. The abdominal signal was differentiated ($F_{m}$) and compared with the accurate standard air flow rate signal ($F_{s}$) obtained by pneumotachometry. $F_{m}$ and $F_{s}$ differed in waveform, but the start and end timings of each breaths were clearly synchronized, demonstrating that the respiratory frequency could be accurately estimated before further processing of $F_{m}$. $F_{m}-F_{s}$ loop showed a nonlinear hysteresis within each breath period, thus 6 piecewise linear approximation was performed, leading to a mean relative error of 14 %. This error level was relatively large for clinical application, though customized calibration seemed feasible for monitoring general variation of ventilation. The present technique would be of convenient and practical application as a new wearable respiratory transducer.

This research has the purpose to examine the images sought for, makeup Consciousness, and behavioral aspects during makeup by the college girls in their 20s in the region of Daeieon and Chungnam that have strong interest in appearance and start color makeup in full scale, who form the main consumer layers in cosmetics market, and to analyze their preference on colors and feelings by the kinds of cosmetics, and their cosmetics purchase behavior. A questionnaire survey on the college girls in Daejeon and Chungnam region has shown the following results. The biggest reason college girls do the makeup was for a refined and pure image as well as protection of skin and covering defects. Their greatest concern was skin protection, and as for color selection, harmonizations of skin color and hair color were the largest consideration. In addition, the type of makeup they do most was foundation makeup, while pink was the most frequent lipstick color, and lip glow was mostly normal colors. However, they mostly answered that they do not use eye shadow, eye runner, and foundation. It was shown that their cosmetics purchase p]aces were specialized discount stores for about 47% nearly half of them, and they consider colors the most for lipsticks and eye shadows, and affinity to skin for foundations and basic cosmetics.

1. By feeding on high Peroxidation Value(POV : 90.4mEq/kg) diets for 180 days, the cultured flounder were induced ceroidosis antificially. 2. The supplementation of glutathione to the diets having POV of 15.5mEq/kg improved the growth of the flounder that had shown depressed by the previous high POV diets(90.4mEq/kg). However, we found very much the same degree of improvement on growth by the supplemented diets of glutathione from 10mg/kg/day to 40mg/kg/day. 3. After 7 days, the flounder fed on the diets supplemented with 10, 30mg/kg/day glufthione start the recover from the accumulated ceroid and damaged tissues. These treated flounders with glutathione showed completely normal histlogical signo after 21 days. The effect of glutathione treatment with high concentration(30mg/kg/day) was better than that of low concentration(10mg/kg/day).

According to the National Fire Data System (NFDS), more than 5,000 vehicle fires have occurred every year for the last 10 years. Vehicle fires are primarily caused by mechanical (breaking system and engine), electrical (wiring and battery), and chemical (oil and fuel gas leakage) problems. The electrical factor has increased with the installation of driver convenience equipment. For example, today, the black box is widely used to provide video data recording of motor vehicle accidents. The black box consists of a front camera, rear camera, and wires. The black box wires are directly connected to the junction box or fuse box from the start battery that operates to provide normal on power supplying for engine stop. It is extremely dangerous when the wires short circuit due to insulation aging, mechanical and electrical stress, etc. In this study, the black box wiring fire risk have been analyzed and investigated when the steady state and abnormal operations, and under the following conditions: wiring arrangements with a high temperature condition, insulation aging, poor contact, and short circuits. The results showed that black box wiring short circuits had a higher fire risk than the other fire hazard elements. To prevent fire hazards caused by black box wiring, the black boxes must be installed by qualified service personnel. Do not modify the wiring, remove the fuse and secure the wiring using cable ties or insulation tape.
