Chrysanthemum is one of the top floriculture species with ornamental and medicinal value. Although chrysanthemum breeding program has contributed to the development of various cultivars so far, it needs to be advanced from the traditional phenotype-based selection to marker-assisted selection (molecular breeding) as shown in major cereal and vegetable crops. Molecular breeding relies on trait-linked molecular markers identified from genetic, molecular, and genomic studies. However, these studies in chrysanthemum are significantly hampered by the reproductive, genetic, and genomic properties of chrysanthemum such as self-incompatibility, inbreeding depression, allohexaploid, heterozygosity, and gigantic genome size. Nevertheless, several genetic studies have constructed genetic linkage maps and identified molecular markers linked to important traits of flower, leaf, and plant architecture. With progress in sequencing technology, chrysanthemum transcriptome has been sequenced to construct reference gene set and identify genes responsible for developments or induced by biotic or abiotic stresses. Recently, a genome sequencing project has been launched on a diploid wild Chrysanthemum species. The massive sequencing information would serve as fundamental resources for molecular breeding of chrysanthemum. In this review, we summarized the current status of molecular genetics and genomics in chrysanthemum and briefly discussed future prospects.

The Myeonbongsan caldera, 10.2X8.0 km, developed within older sequences of sedimentary formations and intermediate composition volcanis in the southern Cheongsong area. Volcanic rocks in the caldera block include lower intermediate volcanics, middle tuffaceous sequences and upper silicic ones. The silicic volcanics, which is named Myeonbongsan Tuff, are composed of crystal-rich ash-flow tuff(300 m) , bedded tuff(30 m) and pumice-rich ash-flow tuff(700 m) in ascending order. Several intrusions dominate the early sequences within the caldera. The caldera collapsed in a trapdoor type when silicic ash-flow tuffs erupted fro major vent area in the caldera. Normal faulting along a ring fault system except the southwestern part dropped the tuffs down to the northrase with a maximum displacement of about 820 m. The Myeonbongsan Tuff is just about 1,030 m thick inside the northeastern caldera, with its base not exposed, and southwestward thinning down. Rhyolitic plug and ring dikes are emplaced along the central vent and the caldera margins, and the ring dikes are cut by plutonic stocks in the southeastern and northwestern parts. The caldera volcanism eviscerated the magma chamber by a series of explosive eruptions during which silicic magma was erupted to form the Myeonbongsan Tuff. Following the last ash-flow eruption, collapse of the chamber roof resulted in the formation of the Myeonbongsan caldera, a subcircular trapdoor-type depression subsiding about 820 m deep. After the collapse, stony to flow-banded rhyolites were emplaced as circular plugs and ring dikes along the central vent and the caldera margins respectively. Finally after the intrusions, another plutons were emplaced as stocks outside the caldera.

This paper deals with suicide that has become a serious problem in our society as well as in the world today from a Christian perspective. Historical position regarding suicide is divided into two; some see it as a brave and honorable act and give approval to it, the others view it as act of giving up the life that is given by God and are opposed to it. Though suicides in the Bible are mostly committed to maintain honor, because of Augustin's position it became negative in Christianity, leading to a thought that one who committed suicide goes to hell. Why then people commit suicide? The views of scholars on the cause of suicide are divided into three; biological, psychological, sociological. My position is that though each or all of them contribute to suicide, yet the decisive factor is on how a person reacts to them. Major factor of suicide is how humans as interpretive beings accept the present despair. On the basis of this understanding of suicide and humans, I conclude this paper with three new recognitions as an essential answer to suicide. First, humans are made in God's image and belong to Him, thus their life is precious. Second, Christianity views humans as ones look for the hope in the future as the eternal life. Third, suicide is a violation of the commandment 'do not kill' yet it is not an act of sin but a disease that needs to be cured. To achieve this Christianity must not only spread the idea of respect for life and also run suicide prevention center every city.

The effects of media violence on the delinquent behavior and violence of children and adolescent are controversial. However, a small but genuine association appears to exist between media violence and aggression or violence. At the present, for a considerable proportion of the population of children and adolescent, delinquent behavior and violence has become a major problem and a way of life. One factor contributing to this problem has been assumed to be the negative influence of mass media including television, drama, videotapes and fiction magazines and so on. Therefore, this paper is intended to discriminate the causal relationship of influence of mass media and juvenile delinquent behavior and violence and to provide nine hypotheses derived from reviewing the literature related to mass media and delinquent behavior. The nine hypotheses are as follows : 1. The presence of modeling mass media crime themes and the extent of interest in and exposure of children and adolescent to media violence themes will be positively correlated to their delinquent(aggressive) behavior. 2. A higher positive correlation will be revealed between interest in and exposure to media violence themes and aggressive behavior among adolescent having parental rejection than among adolescent not experiencing parental rejection. 3. A higher positive relationship will be found between interest in and exposure to mass media crime themes and delinquent behavior among youth having need deprivation than among youth not having need frustration. 4. A higher positive relationship will be presented between the presence of imitating mass media crime themes and interest in and exposure to media violence themes and delinquent or aggressive behavior among youth dysplaying their maladaptive character tendency than among those adolescent dysplaying adaptive character tendency. 5. A higher positively correlating relationship will be shown between interest in and exposure to mass media crime themes and delinquent behavior among youth with a higher scores of depressive trend than among those youth having few or no depression. 6. A higher positive relationship will be found between interest in and exposure to media violence themes and aggressive behavior among adolescent complaining of a high degree of psychosomatic complaints than among those youth having few or no psychosomatic complaints. 7. A higher positive correlation will be appeared between interest in and exposure to mass media crime themes and delinquent behavior among youth displaying aggressive impulsiveness than among those youth having few or no aggressive impulsiveness. 8. A higher positive relationship will be found between interest in and exposure to media violence themes and aggressive behavior among youth having antisocial character or neurotic character with weak ego functioning than among those adolescent not having antisocial character or neurotic character with weak ego functioning. 9. A higher positive correlation will be existed between interest in and exposure to mass media crime themes and delinquent behavior among adolescent displaying the lack of sociality than among those youth not having the lack of sociality. The above nine hypotheses will be tested by statistical methods including Chi-square test, simple correlation, principal component analysis, principal component regression analysis and LISREL path analysis.

Objectives: Continuous positive airway pressure (CPAP) is effective in the treatment of obstructive sleep apnea syndrome (OSAS), but the major limitation of CPAP may be poor compliance. The aims of the study were to investigate the compliance and side effects of CPAP, and to evaluate the efficacy of CPAP in patients with OSAS. Methods: This study enrolled 106 patients with OSAS who took the CPAP treatment. The severity of daytime sleepiness was measured using Epworth Sleepiness Scale (ESS), and sleep quality and depressive symptoms were assessed by Pittsburgh Sleep Quality Index (PSQI) and Beck Depression Inventory (BDI), respectively. Results: During 29 months of the study period, 41.5% of patients were using CPAP and 38.7% of patients stopped using it. Compared to non-compliant patients, compliant patients had a higher PSQI score and obstructive apnea index. Among non-compliant patients, 51.2% of them stopped using CPAP within 1months. 85.7% of non-compliant patients were discomforted by the CPAP, but much more nasopharyngeal symptoms were reported in the compliant group. ESS (p<0.01), PSQI (p<0.01) and BMI (p<0.01) were reduced significantly after CPAP treatment but not BDI (p=0.86). Conclusions: We concluded that CPAP can reduce the daytime sleepiness, nocturnal sleep disturbance, and body mass index. To increase the compliance of CPAP, we suggest that some education and support are needed at the early stage of the CPAP treatment.

The aim of this study is having the status, knowledge and attitude of the high school attendees toward smoking be analyzed, helping to make effective health education methods to diminish adolescent smoking habits. The field self-questionnaire investigation has been performed from Oct 10th through 23rd in 1999. The whole 427 cases were distributed to 1st and 2nd grade students of randomly selected men's high school in Seoul. And 414 cases (97%) were finally selected for analysis after exclusion of cases with insufficient information. The main contents of questionnaire are composed of several sectors; the general characteristics of the interviewees, the relationship with parents, the life style and the peer relationship in school. And smoking-related characteristics are taken into consideration, too. The major findings of the study are as follows: The smoking/non-smoking related factors are, in socio-demographical terms, the grade, average spending per month of the interviewees. And the degree of satisfactory relationship with parents is significant on smoking behavior. The higher, the degree of satisfaction on school life and relationship with designated teacher, the more chances of non-smoking habit. Poor academic grades and peer group dependability of interviewees cause higher smoking habit rate in other way. The self-interviewees grade and cohabitation with parents are also significant on both the attitude toward smoking habit and the knowledge on smoking statistically. The academic history and vocations of the parents and the academic grades of interviewees are also effective variables, but don't make any gap between groups knowledge on smoking. Smoking groups used to have positive attitude toward smoking habit. Both the attitude and knowledge on smoking by the consideration of Quit-smoking have statistically significance. The groups which have negative attitude and high knowledge on smoking quit-smoking into consideration. And the primary cause of quit-smoking is on health by smoking. Depression, stress, adult smoking in the house, peer group pressure, cigarettes advertisements on papers and magazines and smoking scenes on TV have positive correlation on forming smoking habit (p〈0.001) But the knowledge on diseases triggered by smoking has negative correlation on forming smoking habit. (p〈0.05, p〈0.001). Social factors as monthly spending, relationship and communication with parents, the degree of satisfaction in school life, academic grades and student-teacher relationship have crucial negative correlation on smoking habit. That is to say, the higher, the monthly spending is, the worse, the relationship with parents and teachers is, the lower, the academic grades of the student is, the percentage of the interviewees who have smoking habit seems to get higher.

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.

Background: The impairment of the appearance is a major problem for patients with carcinomas of the oral cavity. These patients want to recover their preoperative facial appearance. Some do not realize that this is not always possible and hence develop a desire for further cosmetic and reconstructive surgery (CRS) which often causes psychological problems. Method: The desire of patients for CRS (N = 410; 26%) has been acquired in this $D{\ddot{O}}SAK$ rehab study including multiple reasons such as medical, functional, aesthetic and psychosocial aspects. They relate to the parameters of diagnosis, treatment and postoperative rehabilitation. Patients without the wish for CRS (N = 1155; 74%) served as control group. For the surgeons, knowledge of the patient's views is relevant in the wish for CRS. Nevertheless, it has hardly been investigated for patients postoperatively to complete resection of oral cancer. In this retrospective cross-sectional study, questionnaires with 147 variables were completed during control appointments. Thirty-eight departments of Oral and Maxillofacial Surgery took part, and 1652 German patients at least 6 months after complete cancer resection answered the questions. Additionally, a physician's questionnaire (N = 1489) was available. Statistical analysis was performed with SPSS vers. 22. Results: The patient's assessment of their appearance and scarring are the most important criteria resulting in wishes for CRS. Furthermore, functional limitations such as eating/swallowing, pain of the facial muscles, numb regions in the operating field, dealing with the social environment, return to work, tumour size and location, removal and reconstruction are closely related. Conclusion: The wish for CRS depends on diverse functional psychosocial and psychological parameters. Hence, it has to be issued during conversation to improve rehabilitation. A decision on the medical treatment can be of greater satisfaction if the surgeon knows the patients' needs and is able to compare them with the medical capabilities. The informed consent between doctor and patient in regard to these findings is necessary.

The urban housing market in Korea, especially in Seoul and the Capital region, has been revitalized with massive urban (re)developments and expanding real estate finance after the IMF crisis. This brought about a boom of housing price during the mid-2000s, which has been virtually stabilized by strong regulation policies of the previous government. But with impacts of the recent international financial crisis together with some inherent problems, the housing market of Korea faces with a worry of collapse in relation with the financial market volatility and the serious depression of real economy, and hence the current government attempts to implement strong deregulation policies on the housing market. In this paper it is argued that this kind of volatility of urban housing market seems to be caused by strategies of capital which involve continuous massive urban (re)development, residential segregation and appropriation of monopoly rent(or capital gain), and fictitious capitalization of real estates and integration of real estate market and financial market. In these reasons, the current tendency of urban housing price shows a slow downward, which seems to give the current neoliberal government a rationale for deregulation policies to prevent the downward tendency. But this paper suggests that such a slow downward of housing price shift would have positive effects on the housing market in particular and social and economic situations in general, and hence an alternative housing policy is required to realize such positive effects.
