This study analyzed consumer's harsh complaining behaviors and firm's reactions toward consumers' harsh complaining behavior, and investigated the differences in the firms' reactions according to the characteristics of counselors and customer service centers. In addition, this study attempted to find a strategy and provide guidance regarding consumer's harsh complaining behaviors. The results of this study are discussed below. First, consumer's harsh complaining attitudes were expressed by crude language, violent language, threats, personal attacks, and claims of a high-ranking social position. Consumer's directive, complaining behaviors were repeated on the telephone, and threats of prosecution or disclosure to the public, exposure of habitual product returns, and requests for interviews with superiorsat the representative firm were made. Second, a firm typologies according to its reaction style toward a consumer's harsh complaining behaviors were as follows: Group 1, having a neutral attitude toward consumers and preparation thoroughly regarding their demands; Group 2, having a negative attitude toward consumers and some degree of preparation toward consumers' demands; and finally, Group 3, having a positive attitude toward consumers but offering insufficient reparation regarding consumers' demands. Third, female counselors, counselors having a certified counselor's license, and those much experience working in labor work were more likely to be in Group 3. Male counselors, part-time counselors, and those having experience of many years were more likely to be in Group 2. Group 1 were more likely to have large number of workers at customer service centers, male counselors, and to have large numbers of educational training programs related to the reactions of consumers in the form of dissatisfaction, complaints, how to offer compensation for injuries to consumers, and issues related to PL(product liability). In addition, Group 1 also had more firm level welfare policies related to hight stress levels of consumer counselors and extra types of support regarding harsh consumers. However, Group 2 members were more likely to provide excessive compensation and rewards to harsh consumers. Finally, to react to consumer's harsh complaint efficiently, it was suggested that firms should not treat consumers as harsh consumers, should react to consumers' complaints sincerely, and should take precautionary management efforts as regards consumer dissatisfaction based on better quality control of products. In addition, it was deemed necessary to formulate a management strategy to train competent consumer counselors with a high quality of counselor skill, having standardized and consistent reaction guidance toward consumer complaints and thorough knowledge of compensation rules for consumer injuries and subsequent guidance.

Purpose : To grasp the mental burden for legal responsibility that rescue members have in the performance of job. Method : Questionnaire was presented to rescue members serving in 2 direct control safety centers of fire station located in Seoul, Daejon, Incheon, Kwangju, Busan, Daegu and Ulsan. Results : 1. Questioned whether they have mental burden for legal responsibility while performing job on the site, the rescue members responded : very burdensome in 38.0%, burdensome in 56.0%, moderate in 4.5%, not burdensome in 1.0%, no burden at all in 0.5%. 2. Questioned on the first aid treat for which they have the most mental burden, the rescue members responded : intubation into trachea laryngeal mask airway(LMA) in 40.4%, automatic external defibrillator in 16.3%, securing vein providing sap(medicine) in 10.8%, basic cardiopulmonary resuscitation in 7.2%, eliminating foreign matters inserted into body in 5.4%, stanching external bleeding and treating injury in 5.4%, fixing extremities and spine by using splint in 1.8%, measuring the symptom of vitality in 1.2%, providing oxygen in 0.0%. 3. Questioned whether experiencing legal problem or firm petition(complaint) raised by patient while serving as rescue members, they responded : experiencing a complaint in 41.6%, experiencing no complaint in 58.4%. Asked to indicate the stress level in the scale of which they suffered when lawsuit or firm petition was raised, 0(weak)-10(strong), they answered 8.8 in average. 4. Questioned whether 119 rescue members put the legal responsibility in case that they cause damage to patients intentionally in performing, they responded to the inquiry 3.66 in average(of 5.00). It represented meaningful differences (F=2.874, p=.024) whether they had license or not. 5. In future, legal action will raise against the rescue member by 99% because of people's rights improvement(63.1%), high expectations for the rescue system(29.5%), non-licensed rescue members(5.1%). Conclusion : It was found that the rescue members had severe mental burden for advanced life support which was investigated to have low enforcement rate in the preceding research, for instance, intubation into trachea securing vein management by using automatic external defibrillator. To improve the qualitative level of rescue service in the fire fighting, it may be required to construct the environment that eliminates the mental burden of rescue members for legal responsibility.

아르누보는 예술을 새롭게 개혁하여 젊게 만들고자 하는 목적에서 출발하였다. 역사상의 양식 모방에 반기를 들어 삶과 주변 환경의 총체적 변혁을 포괄하는 현대적이며 시류에 맞는 양식을 요구하는 운동이었다. 장신구 또한 이전의 양식에서 탈피한 새로운 양식을 구축하고자 하였으며 소재와 재료의 새로운 시도와 함께 장인적 기술력이 강조된 섬세한 장신구가 선보였다. 아르누보의 양식은 유럽 전반에 각기 나라의 문화에 맞추어 다양하게 전개되었으며, 짧지만 강렬하게 20세기 이후 양식의 기초가 되었다. 아르누보 이후의 장신구는 산업과 예술 장신구로 나뉘어 발전을 거듭해왔으며 현대에 이르기까지 많은 발전에 영향을 미쳤다. 아르누보는 장신구를 재화의 가치를 넘어서 예술적 가치로서의 확립을 이끌었다. 아르누보의 다양한 조형성을 통해 표현된 심미적 장신구와 생산력과 기능성에 치우친 단조롭고 귀보석 중심의 현대 장신구 디자인과는 차이를 갖는다. 현대에는 개성과 자아표출을 중시하는 문화 예술의 시대로 창의적, 독창적인 디자인을 추구한다. 따라서 시대적 배경과 사상을 통해 표현된 아르누보의 다채로운 색상 표현과 다양한 소재와 모티프의 장신구 양식은 현대 장신구의 새로운 디자인 개발 과 디자인 흐름을 이끌어 가기위한 귀감이 될 것으로 본다.

A large portion of the Korean population has been exposed to toxic humidifier disinfectants (HDs), and considering that the majority of the victims are infants, the magnitude of the damage is expected to be considerably larger than what has currently been revealed. The current victims are voicing problems caused by various diseases, including but not limited to lung, upper respiratory tract, cardiovascular, kidney, musculoskeletal, eye, and skin diseases, etc. However, there has been difficulty in gaining validation for these health problems and identifying causal relationships due to lack of evidence proving that toxic HD is the specific causes of extrapulmonary diseases such as allergic rhinitis. Furthermore, the victims and bereaved families of the HD case have not received any support for psychological distress such as post-traumatic stress disorder, depression, feelings of injustice, and anger caused by the trauma. In addition, because the underlying mechanisms of the toxic materials within the HDs such as polyhexamethylene guanidine phosphate, poly(oxyalkylene guanidine) hydrochloride, chloromethylisothiazolinone /methylisothiazolinone have yet to be determined, the demand for information regarding the HD issue is growing. The victims of the HD cases require support that goes beyond financial aid for medical costs and living expenses. There is a desperate need for government-led integrated support centers that provide individualized support through health screenings; in other words, we need an integrated facility that provides the appropriate social support to allow the victims to recover their physical and mental health, so as to well prepare them to return to a normal life. The implementation of such a plan requires not only the close cooperation between those departments already directly involved such as the Ministry of Environment and the Ministry of Health and Welfare, but also active support on a national scale from pan-governmental consultative bodies.

Hypoxia-inducible factor (HIF) is a key regulator of tumor growth and angiogenesis. Recent studies have shown that, BIX01294, a G9a histone methyltransferase (HMT)-specific inhibitor, induces apoptosis and inhibits the proliferation, migration, and invasion of cancer cells. However, not many studies have investigated whether inhibition of G9a HMT can modulate HIF-$1{\alpha}$ stability and angiogenesis. Here, we show that BIX01294 dose-dependently decreases levels of HIF-$1{\alpha}$ in HepG2 human hepatocellular carcinoma cells. The half-life of HIF-$1{\alpha}$, expression of proline hydroxylase 2 (PHD2), hydroxylated HIF-$1{\alpha}$ and von Hippel-Lindau protein (pVHL) under hypoxic conditions were decreased by BIX01294. The mRNA expression and secretion of vascular endothelial growth factor (VEGF) were also significantly reduced by BIX01294 under hypoxic conditions in HepG2 cells. BIX01294 remarkably decreased angiogenic activity induced by VEGF in vitro, ex vivo, and in vivo, as demonstrated by assays using human umbilical vein endothelial cells (HUVECs), mouse aortic rings, and chick chorioallantoic membranes (CAMs), respectively. Furthermore, BIX01294 suppressed VEGF-induced matrix metalloproteinase 2 (MMP2) activity and inhibited VEGF-induced phosphorylation of VEGF receptor 2 (VEGFR-2), focal adhesion kinase (FAK), and paxillin in HUVECs. In addition, BIX01294 inhibited VEGF-induced formation of actin cytoskeletal stress fibers. In conclusion, we demonstrated that BIX01294 inhibits HIF-$1{\alpha}$ stability and VEGF-induced angiogenesis through the VEGFR-2 signaling pathway and actin cytoskeletal remodeling, indicating a promising approach for developing novel therapeutics to stop tumor progression.

The purpose of this study is to inquire into the degree of health promotion activity of university students, and to confirm the general factors of health promotion behavior in order to offer basic data for a nursing strategy to improve health promotion behavior. For this research, data was collected from university men and women through questionnaires from February 18 to March 20 in 1998. The author develop a measuring instrument on the basis of related reviews of health promoting behavior in the prevention of chronic disease, as well as accounting for demographic factors, biological factors, and circumstanctial factors. The content validity of the instrument was authenticated by two professors of the science of nursing,. and the reliability was confirmed by a 'cronbach' ${\alpha}'$ after moditying the content through a pre-test on 30 students. 475 persons were analyzed in terms of an average, percentage, t-test, ANOVA by 'SPSS-PC'. The analyzed data was the following. 1. The acting degree of health promoting behavior was 3.26 point out of 6. Among the sub-levels of health promoting behavior, the order of importance was the following. self-actualization (4.62), interpersonal(4.60), stress management (4.0l), nutrition(3.68), responsibility(3.1l), liquid and cigaretles ues(2.85), and exercise (2.33). 2. The differences in health promoting behavior according to subject's general character were the following. Age(F=6.012, p=.003), major (F=7.243, P=.000), sex(t=7.60, P=.000), religion(F=2.454, p=.045), living status(F= 2.849, p=.024), health concern of parents(F= 7.596, P=.000), taking health programs(F= 2.710, p =.007), case history of the family( t = -1.980, p=.048). Health promoting behavior is affected by a higher age, majoring in the social sciences, having religion, male, living in the relatives' home, having to take health programs and a higher health concern of the parents. Suggestions: 1. The degree of health promoting behavior appears low in this study. It is crucial, therefore, to develop a health program to improve health promoting behavior and to study how to center the daily health life of students.
