Multiloculated hydrocephalus (MLH) is a condition in which patients have multiple, separate abnormal cerebrospinal fluid collections with no communication between them. Despite technical advancements in pediatric neurosurgery, neurological outcomes are poor in these patients and the approach to this pathology remains problematic especially given individual anatomic complexity and cerebrospinal fluid (CSF) hydrodynamics. A uniform surgical strategy has not yet been developed. Current treatment options for MLH are microsurgical fenestration of separate compartments by open craniotomy or endoscopy, shunt surgery in which multiple catheters are placed in the compartments, and combinations of these modalities. Craniotomy for fenestration allows better visualization of the compartments and membranes, and it can offer easy fenestration or excision of membranes and wide communication of cystic compartments. Hemostasis is more easily achieved. However, because of profound loss of CSF during surgery, open craniotomy is associated with an increased chance of subdural hygroma and/or hematoma collection and shunt malfunction. Endoscopy has advantages such as minimal invasiveness, avoidance of brain retraction, less blood loss, faster operation time, and shorter hospital stay. Disadvantages are also similar to those of open craniotomy. Intraoperative bleeding can usually be easily managed by irrigation or coagulation. However, handling of significant intraoperative bleeding is not as easy. Currently, endoscopic fenestration tends to be performed more often as initial treatment and open craniotomy may be useful in patients requiring repeated endoscopic procedures.

The purpose of this study was to examine the health status of the daughter and daughter- in-law caregivers who care for a cognitively and/or functionally impaired elderly, individual to identify factors that were related to reported health outcomes, and to investigate the negative and positive impacts of family caregiving. Data was collected from 120 daughter and daughter-in-law caregivers and care-recipients using face to face interviews. Most caregivers were daughters- in-law (77.5%) and most care-recipients were female (88.3%). Sixty-eight percent (n=81) of caregivers reported depressive symptomatology. General health also deteriorated by caregiving. Caregivers reported several negative impacts (difficulties): care-recipients' problematic behaviors, deterioration of their own health, pressure from social norms related to family caregiving in Korea, intrafamily conflict, and economic problems. Contrary to the popular belief, caregivers reported diverse positive impacts of family caregiving (68.3%): a sense of filial responsibilities, recognition from elderly, family members, relatives, and society, education for the children, and familial harmony. Higher depression score was predicted by lower family income, the presence of cognitive impairment of care-recipients, and higher level of social conflict of caregivers. Poor general health of caregivers was predicted by older caregivers' age, lower competing roles of caregivers, and poor emotional health. While not seeking to deny the negative aspects of family caregiving, it is also necessary to understand positive aspects of family caregiving to see complete picture of caring for an elderly family member.

The study seeks to understand the effects of boredom proneness on impulse purchasing and smartphone addiction of young consumers. Moreover, the possible mediating role of smartphone addiction is tested for the effect of boredom proneness on impulse purchasing. Nowadays, the effect of emotions on human behavior is generally accepted, and boredom is one of the important and common problematic feelings or moods at various levels of life due to factors like unemployment, not being able to work in a suitable job, not getting appropriate education matching individual abilities, monotony of tasks, and feeling life is meaningless. Investigating the effect of boredom on specific consumer behavior would increase our knowledge about consumer behavior. For the research, a survey was conducted 313 students from Kirikkale University, Keskin Vocational High School; the data were collected by convenience sampling method. The data were processed through statistical tools like exploratory factor analysis, coefficient alphas, and regression analysis. The results of the study reveal that boredom proneness affects impulse purchasing and smartphone addiction. In addition, it is understood that smartphone addiction plays a mediating role in the effect of boredom proneness on impulse purchasing. These results indicate that boredom can be an important factor affecting certain negative consumer behaviors.

Purpose: The purpose of this study was to test the mediating effect of depression on the relationship between gambling severity and cognitive distortion in Koreans with a gambling disorder. Methods: Secondary data from a comprehensive assessment of problematic gambling between 2015 and 2017 on Korea Center on Gambling Problems were used. The subjects in this study were 254 Koreans with that gambling disorder. Data were collected with self-report structured questionnaires which included individual characteristics, the Korean version of Problem Gambling Severity Index, the Center for the Epidemiologic Studies Depression, and the Gambling Related Cognitions Scale. Data were analyzed by using descriptive statistics, independent t-test, one-way ANOVA with the $Scheff{\acute{e}}$ test, Pearson's correlation coefficients, and a mediation analysis of the Baron and Kenny method with the SPSS 22.0 program. Results: Significant correlations emerged among the three variables, gambling severity, depression, and cognitive distortion. Depression exerted a partial mediating effect (${\beta}=.20$, p<.001) on the relationship between gambling severity and cognitive distortion (Sobel test: z=2.33, p=.012). Conclusion: Based on this study's findings, nursing intervention programs focused on managing gambling severity and decreasing depression are highly recommended to alleviate cognitive distortion in people with a gambling disorder.

In metropolitan cities have been reorganizing the routes of the city buses periodically due to changes in the spatial structure and traffic pattern and the lack of supply due to new developments. However, there is a lack of system to comprehensively evaluate the routes. Even if the evaluation index is not clearly defined, it may not be reasonable. Therefore, it is difficult to set the improvement direction when the bus route is reorganized. In this study, the existing evaluation indexes were reviewed and further investigation was conducted on the problematic indexes. In particular, the degree of curvature has been used as a very important index in the evaluation of the route system, but the existing curvature based curvature has a limitation in considering the traffic characteristics of individual users. For this purpose, a virtual city bus network was set up and the degree of curvature was calculated and compared based on the point - based curvature and stopping point based on individual user O/D. In this study, it is considered that more efficient and practical analysis and evaluation are possible in the evaluation of the city bus route system through the curvature considering the individual user O/D based on the stopping point. It is expected that it will be used at the time of reorganization of city bus route performed by individual local governments in the future.

This was a descriptive study designed to identify the level of coping method and its influencing factors on the family caregivers of demented patients, and resolve the family caregivers' level of stress. The data were collected from September 10 to October 10, 2001. Subjects for this study were recruited from four clinics, which were chosen from 15 clinics located in Chunbuk-Do as the study sites because of their cooperation for the study. They were similar in terms of size, the characteristics of the local community. and the population and registration status of the demented patients. The instruments used for the study were as follows: 1. Problematic behaviors of demented patients are measured by the Memory and Behavior Problem Checklist (Zarit, 1980), and the Linguistic Communication Symptoms Questionnaire (Bayles and Tomoeda, 1991) 2. The ability to carry out daily activities was measured using the Barthel Index (1965) and Katz Index (1963), which as well-known ADL assessment methods. 3. Burden was measured using Cost of Care Index by the Kosberg and Cairl (1986). 4. Coping strategy was measured Bell's 18 methods (1977). The data were analyzed using SPSS/PC. The study results were as follows: 1. The total stress score was 2.90 out of a maximum score of 5. The highest score reported was 3.09 on the dimension of restriction of individual and social activities, and the lowest region reported was 2.58 on the dimension of mental and physical health. 2. The total score of the coping method was 2.65 out of a maximum score of 5. The highest score reported was 4.01 on the dimension of thinking that includes an ideation such that it is better than any possible worst case, and the lowest score reported was 1.45 on the dimension of the self-image as a scapegoat. 3. There were significant differences in coping method among the subjects by age (F=2.752 p=0.04), caregiver (F=4.33 p=0.003), care-giving period (F=2.68 p=0.049), and dementia stage (F=2.87 p=0.034). 4. There were highly negative correlations ($\gamma$=-0.301 p=0.000) between problematic behaviors of demented patients and the coping method of their family caregivers. The highest correlation coefficient ($\gamma$=-0.339 p=0.000) was found between aggressive behaviors of the demented patients and the coping method of their family caregivers. 5. There was a low negative correlation ($\gamma$=-0.201 p=0.019) between the ADL of the demented patients and the coping method of their family caregivers. 6. There were highly negative correlations ($\gamma$=-0.213 p=0.005) between stress and the coping method of the family caregivers. The highest correlation was found between financial burden ($\gamma$=-.327 P=.000) and the coping method of the family caregivers. There was no significant correlation among unpleasant aspects of the demented patients, willingness to the demented patients, and the coping method of the family caregivers.

This paper is about the emotional factors in Chiljeongsang(七情傷). To specify the collective term into specific categories, an examination of the meaning of emotion of the East and West was primarily undertaken. The importance of emotion lies in the fact that it provides a link between the individual and the outside world. Emotion was perceived as reflections of the human nature and mental activity by philosophers and psychiatrists throughout history. In the views of psychologists, the focus was on not emotion itself, but rather the emotional experience in human, and its psychological and physiological mechanism. In Traditional Medicine, problematic emotion is called Chiljeong(七情). The term Chiljeongsang(七情傷), which is a compound word of 'Chiljeong(七情)' and 'Sang(傷)' meaning 'damage', is used in referring to illness related to unhealthy emotions. It is used to describe illness caused by Chiljeong(七情) and mental disorders that result in emotional symptoms. It also refers to illness where Chiljeong(七情) plays a role in creating a more direct cause of illness in the larger pathogenic process. In the contents of Chiljeongsang(七情傷) in Traditional Medicine, emotion as causation of Gi(氣) disorder could be found the most, while explanation on the psychological process related to the creation of Chiljeong(七情) was insufficient. This tendency is related to the philosophical basis of Traditional Medicine. Out of the two patterns suggested, the mind-based Chiljeongsang(七情傷) pattern includes the psychological aspects of damage, in which key focus is on the cause that arouses problematic emotion, its process and the meaning this emotion entails. To explain this, concepts from psychiatry, especially Jung's theory on neurosis was adopted. In treating a Chiljeongsang(七情傷) patient, mere knowledge of the physiological changes of the body in terms of Gi(氣) is insufficient. This is because mental factors play a large role in Chiljeongsang(七情傷), and the more a condition is 'mental', the more complex it becomes and the more it influences life as whole. Therefore, the doctor must approach the patient with not only medical knowledge, but also overall knowledge on all aspects of human life.

Various methods have been used in the past to indirectly analyze the craniofacial region. Among these, the lateral and posterior-anterior cephalometircs are used for the evaluation of the dentofacial deformities. However, cephalometircs create inaccuracies because of the inherent enlargement and distortion of the image. The interpretation of cephalometric films is also problematic: the number of anatomic landmarks that can be identified accurately is limited, and the overlap of structures on a radiograph making locating these landmarks difficult. To overcome these problems, computed tomography(CT) has been recommended as an useful modality in the diagnosis, surgical planning, and follow-up of craniofacial anomalies. There is no significant enlargement or distortion of the image, overlap of structure, or tracing error. And the number of anatomic landmarks is vast. The purpose of this study was to examine the orbit and midfacial region using Occlusal Maxillary CT, consisted of slices parallel to the occlusal plane. Based on these CT scan, we provide the data that could be applied to monitor an individual patient's skeletal pattern and the guide to the maxillary osteotomy.

Combined cycle power plant is a system where a gas turbine or steam turbine is used to produce shaft power to drive a generator for producing electrical power and the steam from the HRSG is expanded in a steam turbine for additional shaft power. Combined cycle plant is a one from of cogeneration. The temperature of the exhaust gases from a gas turbine ranges from $400^\circC$ to $600^\circC$, and can be used effectively in a heat recovery steam generator to produce steam. Combined cycle can be classed as a "topping(gas turbine)" and a "bottoming(steam turbine)" cycle. The first cycle, to which most of the heat is supplied, is called the topping cycle. The wasted heat it produces is then utilized in a second process which operates at a lower temperature level and is therefore referred to as a "bottoming cycle". The combination of gas/steam turbine power plant managed to be accepted widely because, first, each individual system has already proven themselves in power plants with a single cycle, therefore, the development costs are low. Secondly, the air as a working medium is relatively non-problematic and inexpensive and can be used in gas turbines at an elevated temperature level over $1000^\circC$. The steam process uses water, which is likewise inexpensive and widely available, but better suited for the medium and low temperature ranges. It, therefore, is quite reasonable to use the steam process for the bottoming cycle. Only recently gas turbines attained inlet temperature that make it possible to design a highly efficient combined cycle. In the present study, performance analysis of a dual pressure combined-cycle power plant is carried out to investigate the influence of topping cycle to combined cycle performance.

Many child actors have appeared in various movies as the Korean film industry continues to evolve. As more children appear in violent and raunchy scenes, there are more concerns about the movie's effect on child actors. In some Western countries, many strategies have been developed for child actors, but for the Korean movie industry, the conditions are still poor for them. Although children who enter the concrete operational period are able to think logically and systematically, they are yet limited by their experiences. Adolescents in the formal operational period try to deal with all of the possibilities and assumptions logically and systematically with freedom from realistic contents and experiences. This period is very important because adolescents become more sensitive to others' feelings and they should develop their ego identity. Several studies have reported the indirect experiences through media including how the movie affected children and adolescents negatively. Depending on the individual's morality, judgment and emotional status, these effects were variable and inconsistent and could be relieved by several interventions. We could anticipate much bigger emotional effect on child actors who are acting directly and then are confronting themselves in the scene. Therefore, we suggest that the emotional effects of the movies on child actors can be managed properly by considering children's cognitive ability and emotional status, and establishing protective strategies before they are exposed to problematic scenes. Of course, it should be followed by evaluating them after the exposure and with follow-up management, if necessary.
