  • In this paper, we propose IoT based smart CCTV security service to prevent crime in blind spot and prevent unexpected fire or danger. In the proposed method, a RC (Radio Control) car is made using Raspberry pie, and a camera and various modules are installed in an RC car. It was then implemented using Raspbian O / S, Apache Web Server, Shell script, Python, PHP, HTML, CSS, Javascript. The RC car provides a security service that informs the manager of the situation by judging the risk of the scene with modules such as video, voice and temperature. Experimental results show that the transmission time of video and audio information is less than 0.1 second. In addition, real-time status transmission was possible in AVG, emergency, and manual mode. It is expected that the proposed method will be applied to the development of smart city by applying it to unmanned vehicles, drones and the like.

  • This study was designed to verify the effect of aromatherapy on menstrual cramps and dysmenorrhea by a quasi experiment (nonequivalent control group pretest-posttest design), from March to October, 2000. The subjects of this experiment consisted of 45 college women with menstrual cramps and dysmenorrhea. They were randomized by 25 for the experimental group and 20 for the control group. Their mean age was 20.6 years, mean menstrual period 28.7 days, mean menstrual cramps(VAS) 7.25, mean dysmenorrhea (Dysmenorrhea Scale) was 27.34. As treatment, aromatherapy was to give effleurrage of the abdomen with lavender, clary sage and rose as aroma oil, almond oil as carrier oil. For the control group, abdominal massage was given with only almond oil. Data collection included menstrual cramps, dysmenorrhea, the change of symptoms(low abdominal pain, lumbago, headache, nausea, fatigue, edema). Menstrual cramps, dysmenorrhea and general, menstrual characteristics of subjects were measured the first day of the pre menstrual period before treatment (pre-test), menstrual cramps, dysmenorrhea, the change of symptoms were measured the first and second day of post menstrual period after treatment (posttest). Data were analyzed by t-test, $\chi^2$- test, repeated measures ANOVA, Cronbach's ${\alpha}$ with SAS Program. The results of this study was as follows; 1. Menstrual cramps was significantly lower in the experimental group(p = .001). 2. Dysmenorrhea was significantly lower in the experimental group(p = .027). 3. Less women in the experimental group complained about the six symptoms than women in the control group after treatment on the first day of the menstrual period(p < 0.05, p < 0.01) In conclusion, these findings indicate that aromatherapy with lavender, clary sage, and rose could be effective to decrease menstrual cramps, and dysmenorrhea. So, aromatherapy could be applied to women suffering with menstrual cramps, dysmenorrhea periodically as an nursing intervention.

  • The uniform motion blur removing algorithm of Cho et al. has the problem that the edge region of the image cannot be restored clearly. We propose the effective algorithm to overcome this problem by using shock filter that reconstructs a blurred step signal into a sharp edge, and convolutional neural network (CNN) that learns by extracting features from the image. Then uniform motion blur kernel is estimated from the latent sharp image to remove blur in the image. The proposed algorithm improved the disadvantages of the conventional algorithm by reconstructing the latent sharp image using shock filter and CNN. Through the experimental results, it was confirmed that the proposed algorithm shows excellent reconstruction performance in objective and subjective image quality than the conventional algorithm.

  • Purpose: The objective of this study was to examine the changes in muscle activity on the anterior deltoid muscle depending on the stretch rate of kinesio tape when applying kinesio tape in healthy adult subjects. Methods: This study was a single-blind randomized controlled trial, including 22 healthy participants (male 15, female 7) with no pathology or past history of shoulder who participated voluntarily. Participants applied a different stretch rate of the kinesio tape, and the functional activity was tested. The stretch rate of kinesio tape was 0%, 10%, and 20%. Subjects lifted a weight (5% of their body weight) to their shoulder height. Subjects lifted a weight up to an angle of 90 degrees in the sagittal plane, and muscle activities (biceps brachii, anterior deltoid, middle deltoid, upper trapezius) were assessed using EMG (electromyography). Analysis of muscle activity was divided into two parts (lift weight and keep holding). The EMG activity of each muscle was normalized to the value of reference voluntary contraction (%RVC) and explored using repeated ANOVA. Results: There were no significant differences in muscle activity depending on the ratio of tape stretch when lifting a weight (p>0.05). There were no significant differences in muscle activity depending on the ratio of tape stretch when holding a weight (p>0.05). Conclusion: According to the results of this study, in the case of applying kinesio taping therapy for healthy people, it was found that the stretch rate of the tape does not have an effect on muscle activity.

  • Objectives: This study was aimed to figure out the effect of Onkyung-tang (OKT) on cold hypersensitivity on feet in female patients. Methods: This study was designed to implement multi-center randomized clinical trial in three korean medical hospitals. The female patients who were enrolled in this study were 112 women who suffered from cold hypersensitivity on feet. They were randomly allocated into OKT group or control group in 1:1 ratio. The primary outcome was change in score of visual analogue scale of hypersensitivity on feet, and the secondary outcomes were thermometer of LU4, PC8, ST32, LR3, visual analogue scale of hypersensitivity on hands, result of cold stress test, and score of World Health Organization Quality of Life-BREF. Results: In both group, the VAS of hypersensitivity on feet and hands was decreased while taking the medicine, and the effect of decreasing the VAS continues for the 4 weeks after the end of medication (p<0.001, 0.003, 0.001). In OKT group, the body temperature difference in lower extremity (ST32-LR3) was steadily decreased at every visit and it was statistically significant(p=0.003, <0.001). On the other hand, in control group, the body temperature difference in lower extremity was decreased only while taking the medicine (p<0.001). Conclusions: OKT significantly reduced discomfort coldness on feet in patients, and the effect of treatment was maintained at least for four weeks after medication.

  • This paper proposes energy management directions to discover the factors of energy loss in homes and buildings and to find ways to improve them. We designed a diagnostic content app for everyday life so that not only housing experts but also the general public can use the detachable thermal imaging camera, which is a strong point of popularity and convenience. The diagnostic results using the app were analyzed using Energy Finder, an energy efficiency diagnostic solution. The survey was conducted on the senior center which is in the blind spots and facilities of the energy welfare area. The target of diagnosis was energy efficiency diagnosis by selecting 30 senior centers for over 15 years from 600 locations located in Naju City, Jeollanam-do. The overall diagnosis was good, but it is considered that the place classified as 7th grade needs to be supplemented to improve energy efficiency.

  • The study compared the cytological features of papillary thyroid carcinoma (PTC) in liquid-based preparations (LBPs) and conventional Pap (CP) smears from fine needle aspiration (FNA), and assessed the feasibility of LBP using the Cell Scan $1500^{TM}$ processor on thyroid FNA samples. Thyroid FNA samples were obtained from 883 consecutive patients. Each sample was divided into two and used for LBPs and CP smears. All were screened independently in a double-blind manner. From the 883 cases, 95 cases were diagnosed as PTC in one or both types of preparation (10.8%). PTC was diagnosed via CP smears in 83 cases (87.4%) and via LBPs in 70 cases (73.7%). However, there were differences in categorization between the paired preparations: Twelve (12) PTCs were misinterpreted in CP smears and 25 PTCs in LBPs. There was a significant discrepancy in the rate of detection of the diagnostic features, with LBPs having a lower detection rate. One (1) case (1.2%) of CP smears and 16 cases (22.9%) of LBPs were categorized as unsatisfactory/nondiagnostic in a total of the 95 PTCs. To conclude, the detection rate of the diagnostic features of PTC is lower in Cell Scan 1500TM samples than in CP smears. However, there are some cases in which a diagnosis of PTC is made in LBPs, but not in CP smears. Therefore, definitive cancer diagnosis in thyroid FNA preparations is likely to result from agreement between direct smears and Cell Scan 1500TM preparations.

  • Objective : The aim of the study was to investigate the therapeutic effect of BVA in the treatment of patients with acute ankle sprain. Design : A prospective randomized double-blind study of BVA was conducted. Setting : The study was done in the Kyungwon University Seoul Hospital from August 1st, 2004 to June 15th, 2005. Patients : 30 patients diagnosed with acute ankle sprain, especially 2nd degree on the Ankle grade pain chart(AGPC) participated in the study, who were divided into two groups (A and B) randomly by a coordinator flipping a coin. Group A and B were relevant to control and BVA group respectively, of which a coordinator never informed any other participant involved. Eventually 13 of 17 in group A and 11 of 13 in Group B finished all the process of the clinical trial. Intervention : In both group A and B, The Procedure of acupuncture treatment was made similar by appearance that four acupoints such as 坵墟(GB40), 中封(LR4), 商丘(SP5), 解谿(ST41) of the injured side were selected and Normal saline aqua-acupuncture(control, as a placebo) or BVA was done and then acupuncture at 坵墟(GB40), 中封(LR4), 商丘(SP5), 解谿(ST41), 足三里(ST36), 陽陵泉(G34) of the affected side was given again. the needles were retained for 20 minutes under the infrared rays. The treatment was given daily for a week. Outcome Measures : Ankle-Hindfoot Scale (AHS) and Visual Analogue Scale(VAS) were followed by three treatments. Statistical Analysis : Analysis regarding variations in AHS and VAS is carried out by applying Mann-Whitney test and Wilcoxon signed rank test sign test with level of significance at 5%. Results : At the end of the treatment, there was significant statistical differences between the two groups in VAS and AHS as well, while at the 3rd day only a VAS showed statistical significance. In each group, both VAS and AHS showed statistical significance along with duration of treatment. Conclusions : BVA was thought to be effective alternatives for relieving symptoms of acute ankle sprain, although further study was needed on the large scale.

  • This paper describes an equalizer using the DFE (Decision Feedback Equalizer) structure, CMA (Constant Modulus Algorithm) and LMS (Least Mean Square) algorithms. The DFE structure has better channel adaptive performance and lower BER than the transversal structure. The proposed equalizer can be used for 16/64 QAM modems. We employ high speed multipliers, square logics and many CSAs (Carry Save Adder) for high speed operations. We have developed floating-point models and fixed-point models using the COSSAP$\^$TM/ CAD tool and developed VHDL filter. The proposed equalizer shows low BER in multipath fading channel. We have performed models. From the simulation results, we employ a 12 tap feedback filter and a 8 tap feedforward logic synthesis using the SYNOPSYS$\^$TM/ CAD tool and the SAMSUNG 0.5$\mu\textrm{m}$ standard cell library (STD80) and verified function and timing simulations. The total number of gates is about 130,000.

  • Purpose: Vasomotor symptoms including hot flash are very common to postmenopausal women. Estrogen therapy was regarded as the best option for relieving menopausal symptoms until 2002, when the Women#s Health Initiative(WHI) reported the side effect of the therapy. Consequently, studies on the complementary and alternative medical herbs and therapy for the management of menopausal symptoms have followed. And so we have reviewed some international clinical studies about the management of postmenopausal symptoms with acupuncture therapy. Methods: "Menopause and acupuncture" was designated as a key word in the search site. Pub Med, and nine papers dealing with hot flash among the relevant RCTs were selected, and then, the effect of acupuncture on hot flash and the way the researches had been done was examined. Results : The intensity of hot flash reduced significantly and the frequency of hot flash was inclined to reduce, but not significantly, compared to the controlled group. Conclusion: Each clinical test has its limitations in point of the number of the required samples. However, it still shows the possibility that acupuncture itself will be effective enough to reduce the intensity of hot flash to a certain degree. It is believed that extensive clinical tests on the effect of acupuncture on hot flash will need to be done hereafter. And when the tests are carried out, it is required to exclude placebo effect, do blind test, and carefully select and control the methods.
