The purpose of the study is to verify whether literature therapy program for prevention of smartphone addiction is effective for adolescents. The subjects of this study were 150 students of J City, K middle school. After completing the program, they were conducted post-test for both the experimental and control groups. The study found that the program was effective in mitigating smartphone addiction but not in reducing the directed life problem. It was also found to be effective in reducing tolerance and loss of control and problems of withdrawal and emotional experience. The study suggests that institutional arrangements are needed for linking with related organizations in the region because it is difficult to effectively prevent the increasing problem of smartphone addiction unless an adolescents program for youth is linked to the school. Therefore, it is necessary to conduct parent education for prevention of smartphone addiction in computer curriculum of school subjects.

Recently, the development of rehabilitation medical technology has resulted in an increased interest in speech therapy equipment. In particular, research on articulation therapy for communication disorders is being actively conducted. Existing methods for the diagnosis and treatment of speech disorders have many limitations, such as traditional tactile perception tests and methods based on empirical judgment of speech therapists. Moreover, the position and tension of the tongue are key factors of speech disorders with regards to articulation. This is a very important factor in the distinction of Korean characters such as lax, fortis, and aspirated consonants. In this study, we proposed a Korean electropalatography (EPG) system to easily measure and monitor the position and tension of the tongue in articulation treatment and diagnosis. In the proposed EPG system, a sensor was fabricated using an AgCl electrode and biocompatible silicon. Furthermore, the measured signal was analyzed by implementing the bio-signal processing module and monitoring program. In particular, the bio-signal was measured by inserting it into the palatal from an experimental control group. As a result, it was confirmed that it could be applied to clinical treatment in speech therapy.

We aimed to provide evidences for developing non-pharmacological intervention in older adults with Mild Cognitive Impairment(MCI) by integrated literature review. The final 16 papers were selected as a result of an integrated literature analysis. All of them are focused on strengthening cognitive activities, while Korean studies have often merged emotional activities such as music therapy and laughter therapy rather than physical activities such as exercise therapy, international studies have combined physical activities rather than emotional activities. The effects of non-pharmacological intervention differed according to the outcome variables. The primary variables were cognitive function and depression, and secondary variables were found to have effects on physical function, activities of daily living (ADL), and self-efficacy. This study contributes to a multidisciplinary approach that can be applied in the clinical field through the development of various non-pharmaceutical intervention for the prevention of dementia in the older adults with MCI.

The active-knee-extension (AKE) test has been used to measure hamstring muscle length. The traditional AKE test measures the popliteal angle to the point of resistance with a 90-degree flexion of the hip fixed by straps, while the stabilized AKE test measures the popliteal angle to the point of resistance with a 90-degree flexion of the hip stabilized using a pressure biofeedback unit providing lumbopelvic stabilization. The purpose of this study was to determine test-retest reliability of the traditional AKE test and stabilized AKE test. Twenty healthy adults participated in the study. The popliteal angles were measured with a digital inclinometer during each test. To assess the test-retest reliability between the 2 test sessions, intraclass correlation coefficients (ICCs) were calculated. The intrasubject coefficient of variation ($CV_{intra}$) was also calculated. To compare the traditional and stabilized AKE tests for changes in pressure, paired t-tests were applied. The results of this study were as follows: 1) ICCs(3,1) value for test-retest reliability was .96 in the traditional AKE test, and was .98 in the stabilized AKE test. 2) The maximal $CV_{intra}$ was 33.7% in the traditional AKE test and 15.7% in the stabilized AKE test. 3) Differences of $6.1{\pm}2.1$ mmHg in pressure were measured in the traditional AKE test, and differences of $1.2{\pm}1.0$ mmHg in pressure were measured in the stabilized AKE test. The results show the traditional and stabilized AKE test to be highly reliable, with test-retest reliability. However, the stabilized AKE test represented less variation and more stabilization than the traditional AKE test. Further study is needed to measure the inter-rater reliability of the stabilized AKE test for generalization and clinical application.

Objective: The aim of this study was to compare sling exercise group to McKenzie exercise group in patients with chronic neck pain. Design: Two group pretest-posttest design. Methods: Twenty subjects who have chronic neck pain were randomly divided into sling exercise group (n=10) and McKenzie exercise (n=10). Sling exercise group (n=10) received sling exercise for 30 minutes per day, twice a week over a 4 week period. And the other group were exercised McKenzie exercise (n=8) for 30 minutes per day, twice a week over a 4 week period. Neck disability index (NDI), Visual analog scale (VAS), algometer, digital manual muscle tester (MMT) and cervical muscle strength and cervical range of motion (ROM) are closely measured to identify the effect of sling exercise and McKenzie exercise. Results: For NDI, VAS, algometer on both trapezius, both rotation of cervical muscle strength, both lateral flexion of cervical muscle strength, cervical extension of ROM and both lateral flexion of ROM were significantly increased after intervention in sling exercise group (p<0.05), For VAS, algometer on both trapezius, left (Lt.) rotation of cervical muscle strength, Lt. lateral flexion of cervical muscle strength, cervical flexion and extension of ROM and Lt. lateral flexion of ROM were significantly increased after than before intervention in McKenzie exercise group (p<0.05). Conclusions: These study outcomes clearly support the notion that sling and McKenzie exercise improved pain, Muscle strength and ROM of patients with chronic neck pain. These results suggest that sling and McKenzie exercise program is suitable for chronic neck pain.

Objectives : This study was performed to compare the effects of Shinbaro pharmacopuncture therapy and bee venom pharmacopuncture therapy in lumbar disc herniation Methods : We compared treatment efficacy of 12 patients with Shinbaro pharmacopuncture therapy and 10 patients with bee venom pharmacopuncture therapy, all of whom were diagnosed with lumbar disc herniation using computed tomography(CT) or magnetic resonance imaging(MRI). We performed a retrospective comparison and analysis during the course of 21 days since admission. To evaluate the treatment efficacy, we recorded the temperatures of the opposite back, hip, and legs with visual analog scale(VAS, back and legs), pain rating scale(PRS), Oswestry disability index(ODI) and digital infrared thermal imaging(DITI) based on patients' medical records. Results : Both treatments were effective in reducing pain and improving functions for lumbar disc herniation patients in terms of VAS, PRS, ODI, DITI. Shinbaro pharmacopuncture group showed slightly better results than the bee venom pharmacopuncture group, but the difference was not significant. Conclusions : For the treatment of lumbar disc herniation, it is suggested that Shinbaro pharmacopuncture therapy is thought to be as effective as bee venom pharmacopuncture therapy without side effects, although further study would be necessary.

This study conducted the following experiment to examine anesthetic effects of 500 kHz ultrasound with lidocaine. Clinical experiment was conducted to compare local anesthetic effects by ultrasound frequencies and drugs with 40 normal adults and it divided subjects into experimental group (I) applying only ultrasound, ointment group (II) applying only lidocaine, phonophoresis group of 1 MHz (III), phonophoresis group of 500 kHz lidocaine (IV) for pain threshold and nerve conduct experiments. Mechanical threshold was measured with von Frey monofilament, thermal pain threshold with halogen lamp and digital thermometer, action potential in median nerve with diagnostic electromyography before and after treatment, and at 30 min., 60 min., 90 min., and 120 min. after treatment. Results of this study can be summarized as follows. Topical anesthesia experiment showed that pain threshold of phonophoresis groups was significantly increased, but there were little differences in ultrasound frequency and drugs among phonophoresis groups. Conduction anesthesia experiment showed that phonophoresis group of 500 kHz using lidocaine had significant difference in pain threshold and sensory nerve conduction compared to ointment group and ultrasound group, but there was no great difference from other phonophresis groups and light nerve block effect was found. It was considered that application of 500 kHz ultrasound using lidocaine will be more effective in deep anesthesia or nerve block than 1 MHz ultrasound. However, researches considering various frequencies, intensities and application hours in low frequency areas including kHz ultrasound are needed to increase deep permeation of drugs.

Objectives The purpose of this study is to evaluate the effectiveness of Chuna therapy for primary dysmenorrhea. Methods Researchers searched on 7 electronic databases (Pubmed, National Digital Science Library, China National Knowledge Infrastructure, Wangfang med online, Korean Studies Information Service System, Research Information Sharing Service and Oriental medicine Advanced Searching Integrated System). The search included Korean, English, Chinese reports and there was no limit on the search period. All of randomized controlled clinical trials (RCTs) that used Chuna manual therapy for primary dysmenorrhea were selected. Results 27 RCTs met required condition. Meta-analysis showed positive results for Chuna manual therapy for primary dysmenorrhea in terms of therapeutic effects and reduction of symptom scores compared to west medicine, herbal medicine, acupucture and other treatments. Conclusions Above results showed that performing chuna is effective in treating dysmenorrhea. However, in some studies, there was no statistic significance between the experimental group and the control group. Also, according to Cochrane Risk of Bias (RoB) evaluation method, quality of the studies were not high enough. Since most of the materials were in Chinese, more high-quality clinical trials about Chuna therapy for primary dysmenorrhea are needed in Korea.

The purpose of serious game for therapy is not to cure patients directly, but to have them cause psychological change, and get positive treatment will. In this study, we extracted 5 elements to be considered to design efficient serious games for psychological therapy through precedent data's analysis. For verification of the extracted elements, we intensively analyzed 2 elements. Those are 'Re-Mission' of which the effect was already proven, and 'SIMS2' which was designed to get the effect of treatment which patients who may experience difficulties in real-world can obtain in virtual space through previous experiences. As a result, material stability, reality, consistency with characters and self-determination of game progress are applied to all the analyzed games, But interactivity with reality is not applied. However, previous researches and validated questionnaire show that interactivity with reality is appropriate element. Consequently, the results of this study will be important materials in designing more efficient serious games for therapy.

This study was performed to evaluate the effect of high frequency therapy applied to the region branching to the external carotid artery for peripheral facial paralysis sequelae. A patient suffering with facial edema due to facial paralysis sequelae had been treated with acupuncture, high frequency therapy on the branch area to the external carotid artery for 7 weeks. The evaluation of clinical outcome was done by degree of swelling by measuring the distance of the face and skin temperature of face through digital infrared thermographic imaging. After treatment, the patient's degree of swelling and the temperature difference between the affected side and normal side was decreased. In addition, the temperature was changed in the entire facial area as well as the treatment point of high frequency therapy. This result shows that acupuncture combined with high frequency therapy at the region branching to the external carotid artery could be an effective way to improve facial blood flow, although further clinical studies will be needed.
