The purpose of this study was intended to investigate influence of consumer's brand loyalty, competitor's brand price and brand switching intention in condition of discount sale of casual apparel products. The data for the study was obtained through the use of an experimental design which was $2{\times}[2{\times}2]$ mixed factorial design. The subjects were 730 college students. The data were analyzed by cluster analysis, ANOVA, simple interaction analysis and simple main-effect analysis. The following results were founded: First, The results indicated that the 3-way interaction effects among consumer's brand loyalty competitor's brand price and discount on brand switching of casual apparel products. Second, the results indicated that the 3-way interaction effects among consumer's brand loyalty competitor's brand price and discount on consumer preference of casual apparel products. These results indicated that low brand loyalty group on casual products showed high preference and high brand switching on competitors brand when competitor's brand price was lower than preferred brand price and discount type was absolute frame. High bran loyalty group on casual apparel products preferred and switched high competitor's brand when discount type was absolute frame.

A 1.83 kg, 9-year-old, spayed female Yorkshire Terrier was referred to the Veterinary Medical Teaching Hospital of Konkuk University for evaluation of an intra-abdominal mass with a week history of vomiting and diarrhea. On physical examination, survey radiography, abdominal ultrasonography, and computed tomography, a huge firm mass was identified in the mid-caudal abdomen. Surgical exploration of the abdominal cavity was performed to remove the mass. The encapsulated mass adhered to the mesentery, tail of the spleen, small intestine, omentum, and right lobe of the pancreas was removed using blunt dissection with dry gauze and cotton swabs. Macroscopic and histopathological examination revealed that the mass was foreign-body granuloma consistent with gauze fiber. Plain abdominal radiography demonstrated no remarkable findings 8 months post-operatively. There was no evidence of vomiting, diarrhea, coughing, difficulty breathing, and cyanosis on exertion 13 months post-operatively.

기초적인 조형 교구인 브릭 제품이 현재는 사용자 계층의 확장에 성공하며, 특유의 가변성과 타 분야와의 뛰어난 연계성을 장점으로 다양한 분야와 독창적인 방식으로의 접목을 시도하고 있다. 하지만 실제로 브릭에 대한 기존의 연구는 그 가치이외의 무한한 가변성과 다변화 차원에서의 연구가 부족하다. 본 연구는 이 같은 인식하에 브릭의 본질적 속성에 관한 이론적 근거를 기반으로 보다 진화한 미래형 브릭 시스템의 현황을 제시하고 체계적으로 분석하는 방식으로 진행하였다. 최종적으로는 3D브릭시스템을 활용한 VR 디자인을 구현해보는 프로세스를 수행하였다. 브릭 시스템의 '다변화 및 확장성'에 관한 연구는 브릭의 미래적 가능성과 활용성을 파악하는데 중요한 자료를 제공 할 것이다.

Choroid plexus papillomas (CPPs) are relatively rare neuroectodermal tumors that develop from choroid plexus epithelial cells and are usually restricted to the ventricles. Extraventricular CPPs are very unusual and can be difficult to diagnose and treat. A 50-year-old male patient was admitted to our clinic complaining of headache and visual deterioration. Neurological examination found no abnormalities except decreased light perception and secondary optic atrophy in the left eye. Endocrine testing revealed normal levels of hormones produced by the pituitary and target glands. Magnetic resonance imaging of the brain revealed a huge regular-shaped lesion in the sellar-suprasellar region occupying the sella turcica and extending into the suprasellar cistern and planum sphenoidale. The lesion was completely excised by microsurgery via an ordinary left-sided pterional approach. Histopathology identified the lesion as a choroid plexus papilloma. Following the case report, literature on the origin, differential diagnosis, and treatment of this rare tumor is reviewed.

Blast loads may considerably affect the response of structures. In previous years, before computer analysis programs, the parameters of blast effects were calculated with empirical methods, consequently some researchers had proposed equations to find out the phenomenon. In recent year's computer analysis programs have developed already, so detailed solutions can be made numerically. This paper describes the blasting response of the structures using numerical and empirical methods. For the purpose, a reinforced concrete retaining wall is modelled using ANSYS Workbench software, and the model is imported to ANSYS AUTODYN software to perform explicit analyses. In AUTDYN software, a sum of TNT explosive is defined 5,5 m away from the wall and solution is done. Numerical results are compared with those of obtained from empirical equations. Similar study is also considered for equal explosive which is the 4 m away from the wall. The results are represented by graphics and contour diagrams of such as displacements and pressures. The results showed that distance of explosive away from the wall is highly affected the structural response of it.

Tracheal collapse is a common respiratory disease in dogs. There are many ways to treat tracheal collapse, one of which is the use of an intraluminal stent. In this study, we divided 21 dogs into two groups and implant conventional stents and new nitinol stents. Comparison of two groups was based on following, feature of stent fracture, form of stent migration, clinical sign improvement, complication and prognosis. Approaching was established via C-arm under spontaneous breathing and placing a stent at the site of collapse. Using radiographic images, determine stent size accurately. For a comparison of identical condition, all intraluminal stents were placed 10 mm caudal from larynx to 10 mm cranial from carina. In this study, new nitinol stents improve the problems of conventional stents and may be effective in the treatment of tracheal collapse in small dogs.

Arduino is used in various places such as education, experimentation, and industry. Due to the easy accessibility of Arduino, it is often used by non-majors, and it is also used in media art and toy programs. Although Arduino is relatively easy to use compared to other devices, it is not easy to control various IoT components at the same time. Some tasks run independently of other tasks, while others run dependently. In this paper, I proposed the Arduino Task Framework to efficiently execute many tasks in these various situations. The design framework of this paper is largely composed of two types: synchronous execution and asynchronous execution. These two execution methods can be combined to create several independent and dependent execution routines. Asynchronous tasks are independently executed tasks and are managed by AsyncTaskGroup, while synchronous tasks are dependently executed tasks and are managed by SyncTaskGroup. AsyncTaskGroup instance and SyncTaskGroup instance are instances of the same Task and can be used in combination with another task. The Arduino framework proposed in this paper simplifies the program structure and can easily compose various tasks.

본 논문에서는 매트릭스 형태로 구성된 키보드의 다이나믹 스캐닝 검출에 있어 눌리는 키의 수에 제한 없이 모든 키를 감지하는 n-키 롤-오버를 구성할 수 있는 소프트웨어 알고리즘을 제시하였다. 제시한 알고리즘은 컴퓨터 키보드 제어용 마이크로컨트롤러의 타이머 인터럽트를 이용하므로 일정하고 정확한 검출 간격을 얻을 수 있으며, 정확한 디바운스 시간을 부여할 수 있는 장점이 있다. 제시한 알고리즘의 효과를 확인하기 위해 건반 형태로 구성된 장난감 키보드에 마이크로컨트롤러를 접속하고 실험을 진행하였으며, 실험 결과 동시에 눌리는 키의 수에 관계없이 모든 키에 대한 검출이 정확히 이루어짐을 확인하였다.

Intravenous catheterization is a common procedure in human and veterinary medicine. Occasionally, a catheter might break within the blood vessel, and the fragment may cause embolization, infections, or other severe complications, and therefore must be removed promptly. For a successful and low-risk removal, the fragment should be localized accurately; however, ultrasound may be challenging to perform on small dogs due to inadequate probes. We report the case of a 2-year-old, 2.6 kg, intact female toy poodle that presented to the veterinary medical center owing to a recent onion intake; the owner requested to induce emesis. A 24 gauge peripheral intravenous catheter was inserted into the cephalic vein prior to the emetic injection. When the clinician removed the catheter, a device breakage was observed. A tourniquet was applied immediately proximal to the elbow. Ultrasonography was performed with a high-frequency small-footprint linear array transducer, also called a hockey-stick probe, to localize the fragment. An additional ultrasound was performed before surgery to confirm the location of the catheter piece, which migrated 5 cm proximally. Afterward, a surgical intervention allowed us to retrieve the fragment. This report highlights the effectiveness of a hockey-stick probe to determine the location of a catheter fragment in small breed dogs.

피아노는 전 세계에서 사랑받는 악기 중 하나이며 연주하는 법도 간단하여 아이들이 음악을 배우는 용도로 많이 사용된다. 이에 따라 장난감 피아노 등 아동을 위한 여러 제품이 출시되었다. 하지만 피아노 연주법이나 악보를 보는 법 등 음악 교육을 위한 피아노는 부족한 실정이다. 이러한 문제를 해결하기 위해 본 논문에서는 아두이노를 활용한 게임 형식의 교육용 피아노를 제안한다. 악보를 LCD 화면에 표시하고, 악보에 표시된 음표를 연주하는 타이밍에 맞춰 건반을 누르면 점수를 획득하는 형식으로써 저렴한 가격으로 재미와 교육을 사로잡을 수 있을 것으로 예상한다.
