The mobile application market has been growing extensively in recent years. Currently, Apple's App Store has more than 400,000 applications and Google's Android Market has above 150,000 applications. Such growth in volumes of mobile applications has created a need to develop a recommender system that assists the users to take the right choice, when searching for a mobile application. In this paper, we study the recommendation system building tools based on collaborative filtering. Specifically, we present a study on comparison analysis of collaborative filtering in Java and R statistical software. We implement the collaborative filtering using Java's Apache Mahout and R's recommenderlab package. We evaluate both methods and describe the advantages and disadvantages of using them in order to implement collaborative filtering.

Purpose: To examine the difference of physical discomfort and childbirth satisfaction between postpartum women with and without having taken Epidural Analgesia. Method: The subjects were divided into one group of 128 primipara taken Epidural Analgesia and the other of the same 70 women who were not taken it. Data were collected by questionnaires of their own physical discomfort and birth satisfaction at postpartum 1 to 2 days in OBGY hospitals, and data were analyzed using SPSS Program. Result: Women having taken epidural analgesia appealed higher physical discomfort than those without it in the lower limbs exercise discomfort, difficult urination, urinary retention, nausea & vomiting, whereas appeared vice versa in breast pain. Among indicators for childbirth satisfaction, women having taken epidural analgesia preferred the same delivery method later again more than those without it. Conclusion: It is confirmed that the method of epidural analgesia is not an absolute way to control labor pain, rather stir physical discomfort after childbirth and does not fully increase the women's childbirth satisfaction. Therefore, it is proposed that nurses should provide the pregnant women the right knowledge and information, thereby enabling them to select the useful method of childbirth to their own course of childbirth and health-recovering after the delivery.

Purpose: This study aims to determine the bioethical subjectivity of nursing students with experience volunteering in elderly care facilities, and the characteristics that comprise the types thereof. Methods: Q methodology, which analyzes the subjectivity of each type, was used. The 37 selected Q statements from 32 participants were classified into the shape of a normal distribution using a 9-point scale. The collected data were analyzed using the PC-QUANL program. Results: The survey revealed that the bioethical subjectivity of nursing students with experience volunteering in elderly care facilities can be divided into three types: a rational dignity emphasis, an autonomous right to life belief, and conflict avoidance. All three attitudes regard human beings as possessing dignity, and life and death as elements to be experienced as aspects of human life. Bioethical values are critical to treatment and care; however, it is sometimes also held that humans have the right to commit suicide. Conclusion: This study enhanced our awareness of nursing students' bioethics. The findings can be used as a basis for the design of differentiated bioethics education according to each type of bioethical subjectivity. This calls for diverse research on bioethics and the implementation of effective bioethics education.

The author analyzed the psychological factors which affected on the way of Mrs. Park in the became a virtuous woman and compared these psychological factors with a virtuous women in Samganghaengsildo based on the relationship between Mrs. Park in and Samganghaengsildo's the virtuous women volume. First of all, it's about the power of authority on women. The volume of Samganghaengsildo's virtuous women was about the group of women who were recognized as virtuous women by the king who had absolute power at the time period. The volume of Samganghaengsildo's virtuous women was very well known for women. This book had a huge impact on women since the government authority educated the women using this book. In addition, the incredible events which were written in Samganghaengsildo indicated that the behavior of virtue was the right thing to follow since even super power recognized it as a good thing to do and the woman might be punished when she didn't follow the behavior of virtue. Second, it was based on the similarity of circumstance and uncertainty for the future. Mrs. Park in showed similar behavioral patterns with a virtuous woman in Samganghaengsildo since she took her role model from the virtuous woman. When Mrs. Park lost her husband, she was not sure about her future and the volume of Samganghaengsildo pointed out that there was another world after the death and she would meet her husband again after the death. In addition, the incorrect information that she would feel better psychologically when she followed her dead husband instead of living herself. Third, it is about the resemblance of obsessive mind and self internalization. The examination of the record of Mrs. Park showed that Mrs. Park tried to internalize integrity, loyalty, and virtue of virtuous women in Samganghaengsildo and became herself like virtuous women. In addition, the woman's obsessive mindset remarkly reflected in Samganghaengsildo. For instance, Mrs. Park in held to the time of death of her husband and the writer who wrote about the behavior of Mrs. Park also emphasized that the time of death of Mrs. Park was closed to the time of the death of her husband. This explained that the obsessive mindset of women in the epic of virtue women could have influence on the women's mind who tried to show the similar behavior with a virtue woman and internalize it. Finally, the people of the day also were not free from it.

Objectives : The purpose of this study is to investigate the differences of pulse wave parameter between the non delivery group (single women with no childbirth experience) and the delivery group (married women who gave birth(s) in delivery). Methods : Sixty one healthy (non delivery) nulliparous women and fifty three delivery women participated in this study. We used 3 dimensional pulse analyser(3D MAC, DAEYOMEDI co., Korea), which measures radial pulse waveform non-invasively by way of tonometry method at 5 different applied pressure levels. From 114 subjects enrolled, pulse wave parameters were measured on the six locations of Chon, Kwan and Cheok of each hands. Results : Delivery group's pulse showed larger values in the following pulse wave parameters (Energy, Ap, RAI, As, Aw, h1, h2, h4, h4/h1, t, t1, t2, t4, Wm, Wm/t). Non delivery group's pulse indicated larger values in the pulse wave parameters such as Energy of left Chon, difference pulse energy between left and right hand, Ad, h5, h5/h1, t5. Conclusions : According to the analysis result, delivery group's pulse has bigger values in most part of pulse wave parameters, especially in Kwan and Cheok which correspond to Liver, Kidney, and Myeong-mun. We interpret these results that delivery women are more mature and stable in reproductive organs than non delivery group, as they have experienced delivery(deliveries) and child-caring through married life.

We present a case of intracranial aneurysm located in the P1 segment of left posterior cerebral artery in the context of tetralogy of Fallot. Complex variations included right aortic arch with abnormal branching. Also, the bilateral vertebral arteries were absent, with a type I persistent proatlantal intersegmental artery of the left side. The aneurysm was treated with endovascular intervention with a Tubridge flow diverter and was noted to be completely cured on 6-month follow-up. We discuss the many considerations in this patient including developmental and modern-era treatment.

The purposes of present study were to determine the major check-points of golf swing from the review of previous studies, and to suggest additional information on the teaching theory of golf. The golf swing motion of 6 male and female elite university golf players were filmed with 16mm Locam II high speed cameras at the speed of 200f/s, and variables such as time, displacement, angle, velocity were calculated and analyzed by 3D Cinematography using DLT method. The results were: 1. Differences were shown in the ratio of weight distribution on the feet, cocking angle, take-back velocity, club-head velocity at impact depending upon the physical characteristics and club used for swing. 2. Time for the down-swing and impact were $0.27{\sim}0.29s$ in men and $0.29{\sim}0.32s$ in women, which was 1/3 of the time for the back-swing. Women showed longer total swing time than men because of longer time in back-swing, follow-through and finish. 3. Men showed larger range of motion in shoulder and knee joints than women, on the other hand women showed larger range of motion in hip joint than men. 4. Cocking motion and right elbow flexion were occurred at the top of back-swing and cocking release was occurred at the moment of impact. Maximum rotations of shoulder and hip joints were found between the top of back-swing and down-swing phase. 5. Women showed lower back-swing velocity than men, and men showed higher club velocity(men: $38.2{\sim}38.6m/s$, women: $35.1{\sim}36.4m/s$) than women.

Purpose: The purpose of this study was to look into back pain, pain disability, labour pain, and related areas of pain experienced by postpartum women. Method: A survey about pain including a Visual Analogue Scale (VAS), Oswestry pain disability, and pain drawing was used in a descriptive research method on 98 women 2-3 days after delivery. Result: 57.1% of those surveyed reported experiencing back pain before pregnancy. 75.5% reported experiencing back pain during pregnancy. The average starting time of back pain for pregnant women was 2.9 months into pregnancy. 48.8% reported the most severe back pain in the last trimester of pregnancy, while most women complained of left and right pubic pain and lumbar area pain during pregnancy. Statistical relations were calculated and menstrual symptoms (F=5.938, p=0.004), back pain prior to pregnancy (F=4.714, p=0.000), back pain during pregnancy (F=-3.429, p=0.001), and back pain disability prior to pregnancy (F=-1.994). Conclusion: There is a relation in postpartum women's back pain between back pain prior to pregnancy and back pain during pregnancy. Pelvic examinations early in pregnancy can determine if back pain will change for the worse or relapse. Therefore, the application of a pain relieving nursing intervention is needed.
