The purposes of this study were to investigate the actual conditions and deal with the psychological characteristics of adolescent cellular phone addicts through the Minnesota Multiphase Personality Inventory (MMPI). The subjects of this study were 407 senior high school students (male 185, female 222) in 2nd grade in Daegu. The cellular phone addiction inventory (CPAI) was designed on the basis of an interview process, referring to the Young's Internet Addiction Self Diagnosis Scale. SPSS version 10.0 was employed for data analysis. The mean score of the adolescent addict group was significantly higher than the non-addict group in Scale Pd, Pa, Pt, Sc and Ma. This result indicates that the cellular phone addict group is likely to suffer from more serious pathological disorders than the non-addict group. The rate of addictive adolescents was significantly higher in the addict group than in the non-addict group in psychological problematic score ranges in Scale Sc (Schizophrenia) and Ma (Hypomania). The study result suggests that adolescents who addictively use a cellular phone will be more likely to show immaturity, instability, impulsive personality, excessive activities, and escapism.

The purpose of this case-control study is to investigate the relationship between storke and stroke risk factors, such as family history and past history. The case-control study over clinical data registered from Daejeon Oriental Medical Hospital in the period of November 2006 to July 2010. Study subjects consisted of 108 patients with acute stroke within 1 month as the case group (Cases) and 108 people who visited hospital for health care as the genreral control group (Controls). The participants had been interviewed by residents to find out their family history and past history. Their blood was taken to check the blood lipid level and liver function. 1. The people whose family history included cerebrovascular accident had more probability of stroke than the people who did not have cerebral vascular accident as their family history. 2. The people who suffered from hypertension had more probability of stroke than the people who did not suffer from hypertension. 3. The people who suffered from diabetes mellitus had more probability of stroke than the people who did not suffer from diabetes mellitus. Based on this study, the people who had cerebral vascular accident as their family history should thoroughly treat their blood pressure and blood sugar level to prevent the cerebral vascular accident.

Background and Objectives : Though voice therapy is proven to be effective in academia, treatment results and satisfaction level are inconsistent in clinics. The inconsistency may rise from diverse vocal cords misuse patterns in patient population as they suffer from different diseases or have bad phonation habits. In order to overcome the limitation, we uniformized patients' vocal cords with injection laryngoplasty prior to voice therapy. The efficacy of voice therapy and consistency in treatment results after injection laryngoplasty were assessed. Materials and Methods : Patients diagnosed with vocal nodules were either treated with injection laryngoplasty followed by voice therapy (combined treatment group) or voice therapy only (voice therapy group). Each group consisted of 15 patients. Acoustic measures (jitter, shimmer, NHR), aerodynamic measures (MPT, Psub, MAFR), and subjective auditory conscious measures (K-VHI, K-VRQOL) between two groups were analyzed. Results : After treatments, both groups improved in terms of acoustic, aerodynamic, and subjective auditory conscious measures compared to pre-treatment. Combined treatment group had statistically significantly greater improvement in shimmer, P in K-VHI, and PF in K-VRQOL compared to voice therapy group. Conclusion : Injection laryngoplasty treatment prior to voice therapy synergizes in treating patients compared to voice therapy only.

Most people suffer from stress during day life because modernized society is very complex and changes fast. Because stress can affect to many kind of physiological phenomena it is even considered as a disease. Therefore, it should be detected earlier, then must be released. When a person is being stressed several bio-signals such as heart rate, etc. are changed. So, those can be detected using medical electronics techniques. In this paper, stress assessment system is studied using random forest algorithm based on heart rate, RR interval and Galvanic skin response. The random forest model was trained and tested using the data set obtained from the bio-signals. It is found that the stress assessment procedure developed in this paper is very useful.

Acid amplifiers derived from a certain class of sulfonates suffer from autocatalytic decomposition in the presence of a strong acid to give corresponding sulfonic acid, which catalyze the composition of the parent sulfonates, leading to the liberation of more of the same sulfonic acids in an exponential manner. In this research we synthesized and evaluated 4-hydroxy-4'-(2-trifluoromethyl)benzenesulfonyloxy isopropylidene dicyclohexane (1), 4,4'-di-(2-trifluoromethyl)benzenesulfonyloxy isopropylidene dicyclohexane (2), 4-hydroxy-4'-(3-trifluoromethyl)benzenesulfonyloxy isopropylidene dicyclohexane (3) and 4,4-di-(3-trifluoromethyl)benzenesulfonyloxy isopropylidene dicyclohexane (4) as novel acid amplifiers with electron withdrawing group. These acid amplifiers (1-4) showed reasonable thermal stability for resist processing temeprature and exhibited higher photosensitivity compared to poly(tert-butyl methacrylate) film without acid amplifiers. Application of acid amplifiers to photofunctional materials, including photoresists, are described as a consequence of the combination of the acid amplifiers with photoacid generator.

Temporomandibular disorders refer to a large group musculoskeletal disorders that originate from the masticatory structures. The AADR recognize that temporomandibular (TMDs) encompass a group of musculoskeletal and neuromuscular conditions that involve the temporomandibular joints (TMJs), the masticatory muscles, and all associated tissues. The signs and symptoms associated with these disorders are diverse, and may include difficulties with chewing, speaking, and other orofacial functions. They also are frequently associated with acute or persistent pain, and the patients often suffer from other painful disorders. The chronic forms of TMD pain may lead to absence from or impairment of work or social interactions, resulting in an overall reduction in the quality of life. However, the consensus of recent scientific literature about currently available technological diagnostic devices for TMDs is that, except for various imaging modalities, none of them shows the sensitivity and specificity required to separate normal subjects from TMD patients or to distinguish among TMD subgroups. This article reviews the various instruments to aid in the diagnosis of TMDs, and the overall validity and practical use of the Electromyography.

Purpose: The purpose of this study was to investigate whether ipsilateral shoulder pain affects the sensorimotor function of the same side shoulder in patients with stroke. Methods: Thirty stroke patients, who were divided into the ipsilateral shoulder pain group (n=15) and the ipsilateral shoulder non-pain group (n=15). Subjects were evaluated on performance of a tracking task, joint reposition test and 9-Hole pegboard test for sensorimotor functions, and Fugl-Meyer test and Motricity Index for functional ability of the contralateral side. Results: In comparison of the two groups, significant differences in performance on functional ability, including the Fugl-Meyer test(both upper and lower limb) and Motricity Index(only lower limb) were observed (p<0.05). With regard to sensorimotor functions, the ipsilateral shoulder pain group were observed significantly poor scores on the Accuracy Index, joint reposition score and 9-Hole pegboard test, when compared with the ipsilateral shoulder non-pain group (p<0.05). Conclusion: We found that ipsilateral shoulder pain could impede accurate performance of a movement and result in deteriorated proprioception of the ipsilateral shoulder. Therefore, careful evaluation and appropriate therapeutic intervention are essential for stroke patients who suffer from ipsilateral shoulder pain.
