This study was conducted to identify convergence factors affecting smoking behavior among college students through the lens of a Health Belief Model. A descriptive study was carried out with 417 college students in Jeju, South Korea. Descriptive statistics and multiple regression analysis were performed using the SPSS 19.0 program. The results showed that sex(t=-7.44, p<.001), pocket money(t=-2.06, p=.040), smoking in the family(t=4.43, p<.001), smoking of close friends(t=9.59, p<.001), and perceived barriers(t=0.87, p=.014), cues to action(t=6.33, p<.001) were statistically significant variables influencing smoking. These findings indicate that among smoking-related and health belief-related variables needs to be considered for preventive and therapeutic approach to stop smoking in college students.
Objective: It was surveyed how to help patients get better treatment for their disease by making complements based on the survey outcomes when the pharmacists guide how to administer medicine. Methods: A total of 142 gastroesophageal reflux disease (GERD) patients answered the self-answering questions consist of 15 items about their general characteristic, lifestyle and dietary style. The frequency of survey materials was analyzed to find out specific figures of surveyed patient's general characteristic, lifestyle and eating habits. Results: Based on the outcomes on analysis there was no difference between female and male patients. The characteristic based on the age group, as ones grow older, the number of GERD patients also increased. In case on the characteristic in lifestyle, many patients had improper habit to treat GERD. The items were smoking habits, stress control habit, sleeping postures and the way in wearing outfits. In case of postures after having a meal, they had right lifestyle. Patients had improper habit in eating food. They enjoyed pungent food and drinks which can hinder the treatment. In case of the time of having meal, eating habit of meat and vegetables and eating food less than an hour before go to bed, this research showed that they have the right lifestyle. Conclusion: This research indicate that pharmacists give guidance GERD patients to stop smoking that is causative of GERD and guide patients have mental stability, and patients avoid pungent food and drinks such as coffee, soda, chocolates and mint candies.

Financial difficulties and claims frequently stop construction works and cause subsequent contract cancellations. However, as the criteria to assess costs have not been established, many cases of legal disputes over the assessment of cancellation costs are taking place and the concerned parties are suffering the loss of time and money. Therefore, the present research aimed at developing a rational and systematic model of cancellation cost assessment following the cancellation of contracts. The research was carried out in the following methods and scopes. 1 ) The research was focused on the assessment of fair cancellation costs from constructors' side for contracts cancelled by any causes for which the owners have liability. 2) To obtain basic materials about cancellation cost assessment methods, contracts, claims, contract cancellations and construction-related laws at home and abroad were examined. 3) A cost assessment model was developed for systematization and efficient operation of cancellation cost assessment, and the reliability and efficiency of the proposed model was verified through a case study. The conclusions drawn from the research are as follows. The importance of the cancellation cost assessment model was confirmed as, using the cancellation cost assessment model, direct cancellation cost and indirect cancellation cost could be assessed systematically, the number of disputable items could be reduced because reasonable evidences of actual spending were presented, and the loss of constructors could be minimized because systematic and rational cost assessment became possible for many disputable cases of indirect cancellation cost, which the constructors had been unable to prove so far though having spent.
A study was carried out to observe the 1% aqueous safranine solution flow speed in longitudinal and radial directions of softwood Thuja orientalis L., diffuse-porous wood Gmelina arborea Roxb., and ring-porous wood Phellodendron amurense Rupr., Longitudinal flow was considered from bottom to top while the radial flow was considered from bark to pith directions. In radial direction, ray cells and in longitudinal direction tracheids, vessel and wood fiber were considered for the measurement of liquid penetration speed at less than 12% moisture contents(MC). The variation of penetration speed for different species was observed and the reasons behind for this variation were explored. The highest radial penetration depth was found in ray parenchyma of T. orientalis but the lowest one was found in ray parenchyma of P. amurense. The average liquid penetration depth in longitudinal trachied of T. orientalis was found the highest among all the other cells. The penetration depth in fiber of G. arborea was found the lowest among the other longitudinal cells. It was found that cell dimension and also meniscus angle of safranine solution with cell walls were the prime factors for the variation of liquid flow speed in wood. Vessel was found to facilitate prime role in longitudinal penetration for hardwood species. The penetration depth in vessel of G. arborea was found highest among all vessels. Anatomical features like ray parenchyma cell length and diameter, end-wall pits number were found also responsible fluid flow differences. Initially liquid penetration speed was high and the nit gradually decreased in an uneven rate. Liquid flow was captured via video and the penetration depths in those cells were measured. It was found that even in presence of abundant rays in hardwood species, penetration depth of liquid in radial direction of softwood species was found high. Herein the ray length, lumen area, end wall pit diameter determined the radial permeability. On the other hand, vessel and fiber structure affected the longitudinal flow of liquids. Following a go-stop-go cycle, the penetration speed of a liquid decreased over time.

The HDD(hard disk drive) using Load/unload(L/UL) technology includes the benefits which are increased areal density, reduced power consumption and improved shock resistance than those of contact-start-stop(CSS). It has been widely used in portable hard disk drive and will become the key technology for developing the small form factor hard disk drive. The main objects of L/UL are no slider-disk contact or no media damage. For realizing those, we must consider many design parameters in L/UL system. In this paper, we focus on lift-off force. The 'lift-off' force, defined as the minimum air bearing force, is another very important indicator of unloading performance. A large amplitude of lift-off force increases the ramp force, the unloading time, the slider oscillation and contact-possibility. To minimize 'lift-off' force we optimizes the slider and suspension using the integrated optimization frame, which automatically integrates the analysis with the optimization and effectively implements the repetitive works between them. In particular, this study is carried out the optimal design considering the process of modes tracking through the entire optimization processes. As a result, we yield the equation which can easily find a lift-off force and structural optimization for suspension.

This paper describes the system for detecting vehicles in the rear and rear-side that access between sidewalk and bus stopped to city road at day by computer vision-based method. This system informs appearance of vehicles to bus driver and passenger for the safety of a bus passenger getting off. The camera mounted on the top portion of the bus exit door gets the rear and rear-side image of the bus whenever a bus stops at the stop. The system sets search area between bus and sidewalk from this image and detects a vehicle by using change of image and sobel filtering in this area. From a central point of the vehicle detected, we can find out the distance, speed and direction by its location, width and length. It alarms the driver and passengers when it's judged that dangerous situation for the passenger getting off happens. This experiment results in a detection rate more than 87% in driving by bus on the road.

This study focuses on the development of a new method of H-shaped beam-to-square column connection with an outer diaphragm and a field welding. The specific type of beam-to-column connection with an external stiffener, using field welding, is proposed. The structural behavior of this connection was examined experimentally. Two loading type tests were conducted under the experimental parameters given as details. First described was the symmetrical loading test, which supported both ends or a beam simply and applied a load from the column to the pend (What does this mean?) to investigate a fundamental characteristic of this connection. Further described was the anti-symmetrical loading test, which carried out simple support of the column'stop end and the column base, and applied a load from both ends of a beam to investigate the structural performance of this connection. From the results, it is clear that the external- stiffener-type connection proposed in this paper is the reliable connection method.

Scolpendra subspinipes (centipede) is pungent in flavor, activates the channels to stop pain, and, removes toxins and resolves masses. So it has been used as a folk remedy. We researched folk remedies which used centipede as a single medicine and results of its prior clinical and experimental study, and figured out that centipedes are effective on ulcerative disease, herpes zoster, clavus, insect bite, inflammatory disease, furunculus, pain disease by external therapy, and oral administration is effective on anti-cancer such as hepatoma and uterine cancer, cerebrovascular disease, inhibition of atherosclerosis, sedation of central nervous system, antipyretic action, and anti-inflammation, and centipede Herb-Acupuncture is effective on inflammatory disease and pain disease. Centipede preparation materials for external therapy were sesame oil, perilla oil, vinegar, salt, and, burnt alum. Fumigation of centipede treated paronychia, pertussis, and hemorrhoids. For the external therapy, the way of centipede powder mixing with other materials has been used. It is needed that we use dusted powder to make skin absorb its ingredients more easily, and we study intensely minor ingredients to make centipede components absorbed more effectively and do pharmacological action. Also, fumigation, a kind of another external therapy, is considered to be effective treatment of upper respiratory infection like pertussis, so it needs an in-depth study on centipede fumigation.
Background: Surgical management of recurrent pleomorphic adenoma of the parotid gland has a considerable risk of facial nerve injury and a high re-recurrence rate. To obtain more insight into the issue of recurrent pleomorphic adenoma and more specifically to evaluate our experience and results of treatment, a retrospective study was carried out. Materials and Methods: During the period from 1989 to 2002, the medical records of 14 patients who underwent a operation for recurrent pleomorphic adenoma of the parotid gland were reviewed retrospectively. The initial operation for parotid tumor, clinical features of recurrence, reoperation after recurrence, po stop complication were analysed. Results: The male to female ratio was 6 : 9. Median age of the patients at the time of the initial operation was 33 years and at the time of the reoperation was 43 years. The median interval until recurrence was 105 months (6-252 months). The initial operations performed were excision or enucleation in 10 patients, superficial parotidectomy in 3 patients, total parotidectmy in 1 patients. The thirteen patients were underwent reoperation (8 superficial parotidectomies, 3 total parotidectomies, 1 neartotal parotidectomy, 1 wide excision). The facial nerve paralysis after the reoperation occured in 6 patients but all of them were recovered from 3 months to 1 year after surgery. Conclusion: In the management of pleomorphic adenoma of the parotid gland, excision or enucleation is to be avoided due to the higher recurrence rate and superficial or total parotidectomy with preservation of the facial nerve are to be preferred. Because the risk of facial nerve injury during operation for the recurrent tumor was higher than initial surgery, more careful surgical procedure is mandatory for preserving the facial nerve.

The research vessel NARA equipped with an azimuth thruster system was built in 2015. There are few vessels with this propulsion system in Korea. This vessel has two modes such as the normal for maneuvering and the power for investigation, and the other two modes as one axis and two axes on the operating. This type of vessels does not seem to have a clear grasp of the maneuvering character in comparison with the vessel with a conventional propulsion system. So the authors carried out the sea test for the turning, the zigzag and the inclination, and the results are as follows. In turning test, the case of using the two axes mode is much better than the case of using the one axis mode for the elements of turning, such as advance, transfer, tactical diameter and final diameter, but turning hard over the rudder in full speed is very vulnerable to capsize in both modes. In zigzag test, the yaw quicking responsibility index, T is very large excessively, which means a bad counter maneuvering ability, so an operator has to keep in mind that in turning operation. If necessary to avoid collision at head on situation, it may be a more effective method to use the crash astern stop than the turning according to the conditions and circumstances for the shortest stopping distance is very short.
