Dual left anterior descending artery (LAD) is a rare congenital coronary artery anomaly with a prevalence of approximately 1% in the general population. To date, 10 types of dual LAD artery anomalies have been reported. Among these, type 4 is one of the rarest. Knowledge and recognition of the dual LAD artery are important for correct diagnosis and planning of coronary bypass surgery and percutaneous coronary intervention. We report a case of a 59-year-old male with type 4 dual LAD artery who presented with dyspepsia and sweating for several months and had approximately 50%-70% stenosis in a major diagonal branch off the short LAD artery.

Objectives : In this study I made investigations how 'strange hunger' and 'compulsive overeating' threatening the ego could be resolved and healed. And I aim to present a healing model of psychotherapy and analysis as one of methods of treatment for 'eating disorder'. Methods : The analysands of this study were outpatients who visited the department of psychiatry of Yong-In Mental Hospital from March 2008 to February 2017 with 'hunger' and 'compulsive overeating' as their chief complaints. This study is based on the detailed records of the process of analysis including dreams and visions. Results : 1) Throughout the process of analysis that explore both consciousness and unconsciousness(dream, vision), hunger and compulsive overeating is improved and healed in all analysands. 2) The Imago of 'Snake' appeared in dreams and visions of all analysands. 3) By suffering impulse rather than acting it out, impulse transformes itself into 'Imago'. As impulse transforms into 'Imago' and reveals the 'meaning' of it, ego-threatening power of impulse weakens and mood is calmed. And as a result, synthesis of consciousness and unconsciousness and creative transformation of personality can be possible. Conclusions : In some people, 'hunger' and 'compulsive overeating' are 'creative impulses' that aim 'Self-realization' which can be fruited as creative transformation of personality and as creative transformation in the relation with the world. 'Creative impulses', which often can be experienced as instinctive impulse or emotional suffering unless ego realizes the meaning, reveal the meaning in dreams or visions through 'Imago' and 'Symbol'.

The purpose of this paper is to examine the impact of conflict and nurturing factors for the divorced parent on the behavioral adaptation of their children. The participants in this study include 216 children in divorced families nationwide. Structural Equation Modeling with LISREL8 was used for statistical method. In order to achieve the purpose, researchers firstly tried to test a construct validity of conceptual variables(parental conflict, negative attitude of parental nurturing, child's belief about parental divorce, child's aggression and child's delinquence) by employing exploratory factor analysis(EFA) and confirmatory factor analysis(CFA). Result showed that all the five conceptual variables were discriminated. It was identified as the fit index of path structure was good(CFI=.955, NNFI=.947, RMSEA=.046). The specific result were as follows: 1. the parental conflict(${\xi}1$) was directly related to the negative attitude of parental nurturing(${\eta}1$) and the child's belief about parental divorce(${\eta}2$). 2. the parental conflict(${\xi}1$) was indirectly related to child's belief about parental divorce(${\eta}2$), the child's aggression(${\eta}3$) and delinquence(${\eta}4$). 3. the negative attitude of parental nurturing(${\eta}1$) was directly related to the child's belief about parental divorce(${\eta}2$). 4. the negative attitude of parental nurturing(${\eta}1$) was indirectly related to the child's aggression(${\eta}3$) and delinquence(${\eta}4$). Lastly, and, the child's belief about parental divorce(${\eta}2$) was directly related to the child's aggression(${\eta}3$) and delinquence(${\eta}4$). Researchers also identified the mediating effect of the parental nurturing between parental conflict and child's belief about parental divorce. On the basis of these results, this article provided some suggestions for promoting of children welfare.

Purpose : Breastfeeding should be recommended for infants born to mothers with chronic hepatitis B Infection after postexposure prophylaxis. However, high proportion of these mothers are reluctant to engage in breastfeeding in Korea. This survey was taken to identify the cause of that reluctance. Method : Questionnaires were given to mothers with chronic hepatitis B infection who were registered at the 'Hepatitis B Perinatal Transmission Prevention Program' operated by Korea Center for Disease Control and Prevention. They visited a community health center for blood sample collection and signed a consent paper. The questionnaires were sent to the mothers. Result : Among 839 mailed questionnaires, 114 were returned marked 'address unknown'. The overall reply rate was 17% (n=125). Among responders, 52% (n=62) were breastfeeding and 48% (n=60) were formula-feeding. The most influential factor for breastfeeding was the mother's own decision (75%) and the obstetrician's recommendation (17%). For formulafeeding mothers, their decisions were influenced by obstetricians (57%), and by their own thinking (28%). The relationship between breastfeeding and perinatal prophylaxis failure was recognized as 45% 'related' and 50% 'not-related'. A total of 91% of breastfeeding mothers replied that they will breast-feed again. Among formula-feeding mothers, 78% answered that they will breast-feed if they were known that 'there is no direct relationship between breastfeeding and perinatal prophylaxis failure'. Conclusion : Despite the fact that there is no direct relationship between breastfeeding and perinatal prophylaxis failure, many were reluctant to breast-feed. Healthcare professionals have influence over the mothers for decision making. It will be necessary to educate healthcare personnel so that they can make a conceptual change as well as to promote the fact to the general public.

The number of internet users and the scale of electronic on-line trading are on the increase due to the development of information technology and the internet. The aim of this study was to monitor the accuracy of country-of-origin labels and the indicated contents of meat available by electronic on-line trading by using a structural interview sheet for 100 on-line meat product markets. The result of this investigation showed a 100% level of accuracy for business name and telephone number whereas the company address, meat manufacturer and supplier, and business registration were less reliable. We also investigated the accuracy of site policy, e-mail address, and fax number. The results showed that the accuracy of fax numbers was the lowest. The product name and the kind of meat actually in the product showed a 100% level of conformity, while the price (96.3%), place of origin (93.6%), capacity (90.4%), meat parts (80.9%) and contents of the product (73.4%) showed a relatively low level of conformity. Serious safety issues were exposed by the disturbingly low 20.2% accuracy of indicated expiration dates and 5.3% accuracy of indicated manufacturing dates. To ensure food safety, it is essential to improve consumer understanding and trust regarding food safety through continuous public relations. More education and information are needed to raise consumer awareness of the facts versus myths regarding food safety.

Hoarseness, caused by any condition that interfers with normal phonatory function of larynx, is the most important symtom of the laryngeal disease. The air pollution is the serious social problom today due to irritation of the respiratory mucosa and secondary respiratory disease. It is significant to study whether, in resent years, the patients with complant of hoarseness has being increased or decreased, compare to past years. The authors report a statistical analysis on 400 cases with chief complain of horseness at the Department of Otolaryngology, Hanil Hospital during past 7 years from Jan. I, 1970 to Dec. 31, 1976. The results were as follows; 1) Among total out patients of 14, 731 who visited to the department of otolaryngology, the patients with hoarseness numbered to 400(2.7%). 2) Among total of 400 cases, male were 211 and female were 189. The incidence was slightly higher in male than female with ratio 1.1 to 1 in sex distribution. 3) The uderlying diseases causing hoarseness in order of frequency were Acute Laryngitis (158 cases, 39.5%), Chronic Laryngitis (103 cases, 27.3 %), Vccal Nodule (37 cases, 9.3%), Vocal cord paralysis (34 cases, 8.5%), Laryngeal Polyp (32 cases, 8%), Laryngeal Ca. (13 cases, 3.5%), and Laryngeal Tbc. (9 cases, 2.3%). Particulary, Laryngeal Ca., Laryngeal polyp and Laryngeal Papilloma were extremely high in male but the remainings were equally distributed in sex group distribution. 4) The highest incidence occurred in 3rd decade (113 cases, 28.5%), the next 4th and 2nd decade in the age group distribution. Acute and Chronic Laryngitis were widely distributed in age group distribution but the highest incidence was noted between 3rd and 4th decade (145 cases, 55.5%). The highest incidence was 3rd decade in Laryngeal polyp, 3rd and 4th decade in Vocal Nodule, 4th and 5th decade in Laryngeal Tbc. and Vocal cord paralysis and 5th decade in Laryngeal Ca. 5) The underlying disease causing hoarsness were evenly occurred in monthly distribution but relatively high incidence was observed between April and June (35.5%) compared to winter. 6) In durational distribution, the highest incidence was within 10 days (26%) from onset to consultation. 317 cases (80%) were visited to the clinic within 1 year.

Impaction is defined as the cessation of the eruption of the tooth caused by a clinically or radiographically detectable physical barrier in the eruption path or by the ectopic position of tooth germ. Besides the third molars and the maxillary canines, the most common impacted tooth is the second premolar. The overall frequency of premolar impaction has been reported to be 0.5%. In some cases, orthodontic traction and surgical repositioning may be indicated. When impacted second premolar is involved with prolonged retained second primary molar, extraction of primary molar and space maintenance lead to eruption of second premolar. In these cases, all patients visited to department of pediatric dentistry of Kyungpook National University Hospital for the chief complaint of unerupted second premolar. Extraction of prolonged retained second primary molar and space management are tried for spontaneous eruption of impacted second premolar tooth. The results were as follows: 1. When impacted second premolar is involved with prolonged retained second primary molar, minimal treatment via elimination of primary molar leads to successful results. 2. Proper space management and periodic radiographic examination are required before eruption of second premolar. 3. Sufficient time must be allowed for confirm of tooth movement before orthodontic traction or surgical repositioning. 4. The result is more successful in incomplete root development.

Purpose : Multidrug-resistant Acinetobacter baumannii (A. baumannii) is recognized to be the most difficult pathogen to control and treat in pediatric burn centers. We analyzed the antibiotic susceptibility pattern of A. baumannii in our pediatric burn intensive care unit during the past 7 years. Methods : We retrospectively evaluated 56 patients (105 samples) under the age 15 years and who were infected with A. baumannii between January 1999 and December 2005. Results : Fot the 56 patients, the ratio of males to females was 1.15:1 and the median age was 48.3 months. The sites of 105 isolates were wounds (65%), sputum (20%), blood (6 %), cutdown tips (5%), endo-tip tubes (2%) and urine (2%). A. baumannii presented yearround. The annual antimicrobial resistance rate increased and the multidrug resistant rate for two or more antibiotics was 93.33%. For 3 patients in whom resistance emerged, the interval period between the susceptible and resistant strains after antibiotic use was a mean of 10 days. The A. baumannii isolated from blood were all multi-drug resistant pathogens. Conclusion : Multidrug resistance of A. baumannii is increasing. Strict infection control guidelines and active surveillance are needed for the prevention and treatment of A. baumannii in hospitals.

Currently in a Ubiquitous Sensor Network (USN) research field, supporting mobility is recognized as an important technology. MIPv6 and Network Mobility(NEMO) Basic Support Protocol are standard protocols to support mobility in the Internet. However, if they are applied to USN with no modification, handoff performance decreases due to the size of their binding message. An existing lightweight protocol for NEMO protocol has a compatibility problem of Sequence Num. and does not optimally compress binding messages considering 6LoWPAN network structure and addressing. This paper proposes optimal header compression which supports node-based mobility and network-based mobility. Our optimal compression technique compresses a 32bytes binding update(BU) message and a 12bytes binding ACK(BA) message of MIPv6 into 13bytes and 3bytes, and a 40bytes BU message and a 12bytes BA message of NEMO protocol into 13bytes and 3bytes. The result shows that our protocol compresses 15bytes (NEMO-BU) and 1byte (NEMO-BA) more than the existing protocol and achieves 8.72% handoff performance improvement.
