  • The efficacy of a medicinal herb tea (MHT) for assisting smoking cessation and for reducing withdrawal symptoms was evaluated by a placebo controlled subjective test in 100 male smokers. The MHT group experienced less craving for the taste of tobacco, and was more successful at quitting smoking. Among the subjects continuing to the final stage, 23 subjects (38.3 %) who took the MHT and 2 subjects (10.0 %) who took the placebo tea succeeded in quitting smoking. In the group taking MHT, urinary cotinine concentration increased during the first 2 weeks and then greatly decreased from weeks 2 to 4. The urinary cotinine concentration in the MHT group at week 0 was 38.6 mol/L but decreased to 24.5 mol/L by the end of week 4. MHT also reduced withdrawal symptoms, a frequent reason for failure in reducing or quitting smoking. The effects of the herbal tea on smoking cessation and withdrawal symptoms may be attributed to increased metabolism of nicotine and other effects of unidentified components of the herbal ingredients.

  • DNA sequencing provides fundamental data in genomics, bioinformatics, biology and many other research areas. With the emergent evolution in DNA sequencing technology, a massive amount of genomic data is produced every day, mainly DNA sequences, craving for more storage and bandwidth. Unfortunately, managing, analyzing and specifically storing these large amounts of data become a major scientific challenge for bioinformatics. Those large volumes of data also require a fast transmission, effective storage, superior functionality and provision of quick access to any record. Data storage costs have a considerable proportion of total cost in the formation and analysis of DNA sequences. In particular, there is a need of highly control of disk storage capacity of DNA sequences but the standard compression techniques unsuccessful to compress these sequences. Several specialized techniques were introduced for this purpose. Therefore, to overcome all these above challenges, lossless compression techniques have become necessary. In this paper, it is described a new DNA compression mechanism of pattern matching extended Compression algorithm that read the input sequence as segments and find the matching pattern and store it in a permanent or temporary table based on number of bases. The remaining unmatched sequence is been converted into the binary form and then it is been grouped into binary bits i.e. of seven bits and gain these bits are been converted into an ASCII form. Finally, the proposed algorithm dynamically calculates the compression ratio. Thus the results show that pattern matching extended Compression algorithm outperforms cutting-edge compressors and proves its efficiency in terms of compression ratio regardless of the file size of the data.

  • This paper focuses on the emerging patterns of educational mobility and unskilled labor migration from Uzbekistan to Japan and South Korea. Labor migration and educational mobility are becoming the next "horizon" in the expanded relationship between East and Central Asia, powered by several factors, including the efforts by Japan and South Korea to build "original" people-oriented policy engagements with the region and the demand from Central Asian states, such as Uzbekistan, to provide more labor opportunities to their young and growing populations. This paper presents the initial findings of a pilot survey that explores and occasionally compares the experiences of Uzbek migrants to Japan and South Korea, using datasets of face-to-face interviews related to various aspects of life in Japan and South Korea. The interviews were conducted face to face and online (Telegram, Skype, etc.) with 66 migrants and Japanese language school students (whom this paper treats as labor migrants masquerading as students) in Japan from November 2019 to January 2020 as well as online with 30 laborers and students in South Korea from August to September 2020.

  • Objectives: Gaming disorder has been viewed as a disease in the DSM-5 and ICD-11. Its essential symptoms are loss of control over gaming, gaming becoming a markedly prioritized activity over other activities of daily living, and continued and excessive use of gaming despite negative problems occurring. Methods: Children and adolescents are especially vulnerable to gaming disorder because the striatal pathways related to reward develop earlier than the control regions of the prefrontal cortex. It is also associated with decreased dopamine D2 receptors. Addiction is related to 'want' and is explained by incentive-sensitization. In addition, allostasis, in which homeostasis is continuously achieved at a new target value, is also related to gaming disorder. In addition, personality causes, unchangeable factors, and external factors can influence on the onset of gaming disorder. Results: Prevention is the best solution for gaming disorder, and the role of parents is important. For gaming disorder, bupropion is used, cognitive-behavioral therapy and family-based therapy are also beneficial. Herbal medicine treatment such as Antler velvet and ginseng can be effective. Electroacupuncture and acupuncture using PC6, SP6, and LR3 has a correlation with relieving Internet craving. Ear-acupuncture was also effective in treating addiction. Conclusion: Psychologically, 'want' is an intense longing for reward and motivation, and is related to addiction. This 'want' may rather be related to avoidance, and game addiction in children and adolescents may be due to wanting to escape from academic stress or avoidance of comparison. Therefore, the importance of 'like', which gives pleasure in itself, increases. It can also be explained with Sasang Constitutional Medicine.

  • Many young women suffer from premenstrual syndrome (PMS). The purpose of this study was to examine the effect of isoflavone on serum sex hormone and PMS during the luteal phase of the menstrual cycle. We investigated the incidence of PMS in 116 Korean female college students. The incidence of PMS was $19.8\%$. Among them, 9 PMS and 13 control were given 90 mg isoflavone per day during 2 menstrual cycles. The changes in anthropometric measurements, dietary intakes, serum parameters including sex hormones, and PMS symptoms were observed. Isoflavone supplementation did not affect anthropometric measurements. However, SBP and DBP were significantly decreased in control. Dietary intakes were not changed after supplementation of isoflavones. Serum SHBG was lower in PMS group than in control and significantly decreased in control with isoflavone supplementation. PMS symptoms such as backache, sweet, salty, and fatty food craving, coffee/tea drinking, and anxiety were significantly lessened. Based on these results, isoflavone supplementation may benefit young women by reducing some of PMS. Further studies of soy isoflavones effect on sex hormone and PMS may help to prepare for PMS management.

  • Objectives Many studies have suggested different neurobiological findings and clinical courses in alcoholism. Recently, subtyping in alcohol dependence has become essential to overcome the heterogeneity of patients. Among several criteria of subtypes, Lesch's typology is proposed to integrate biological, social, and psychological factors. This review provides neurobiological findings and treatment-responses of alcohol dependence according to Lesch's typology. Method We searched the international published medical literature using the search terms 'Lesch's typology' and 'alcohol dependence' and using the limits 'human'. Results We identified 17 studies with subjects of alcohol dependence according to Lesch's typology. Conclusion They indicated that each subtype of Lesch's typology can have specific neurobiological factors and different clinical responses as follows. Lesch's subtype 1 is characterized by severe withdrawal symptoms and associated with elevated glutamate and homocysteine. Lesch's subtype 2 is defined by individuals who drink alcohol as self-medication for anxiety. Their craving has significant positive correlations with prolactin, leptin level, or intake-volume (vasopressin). Lesch's subtype 4 is related to cerebral dysfunction and associated with increased glutamate and left-handedness. Clinical trials showed that naltrexone was effective in Lesch's subtype 3 and 4 patients, while acamprosate was effective in the subtypes 1 and 2.

  • Studies have shown that both the psychomotor stimulant effects and rewarding properties of addictive drugs, including morphine, are sensitized by repeated drug administration and it is suggested that both of these effects are mediated by the same or closely overlapping dopamine systems. Specifically, the mesolimbic dopamine system has been implicated in the reinforcing and sensitizing properties of morphine. In oriental medicine, Shenmen (HT7) point on the heart channel has been used to treat mental and psychosomatic disorders. This study was designed to investigate the effect of acupuncture on acute and repeated morphine-induced changes in extracellular dopamine levels using in vivo microdialysis and morphine-induced behavioral changes. In the morphine sensitization experiment, male Sprague-Dawley rats were treated twice a day for three days with increasing doses of morphine (10, 20 and 40 mg/kg, s.c.) or with saline. After 15 days of withdrawal, rats were challenged with morphine hydrochloride (5mg/kg, s.c.). Acupuncture was applied at bilateral Shenmen (HT7) points for 1 min after the morphine challenge. In the acute experiment, rats also received acupuncture for 1 min after an injection of morphine hydrochloride (5 mg/kg, s.c.). Results showed that acupuncture at the specific acupoint HT7, but not at control points (tail) significantly decreased both dopamine release and behavior induced by a systemic morphine challenge or a single sc morphine injection in the acute animals. These results suggest that reduction in sensitization may be one mechanism whereby acupuncture alleviates morphine craving in addicts.

  • A control of the body posture and movement is maintained by the vestibular system, vision, and proprioceptors. Afferent signals from those receptors are transmitted to the vestibular nuclear complex, and the efferent signals from the vestibular nuclear complex control the eye movement and skeletal muscle contract. The postural disturbance caused by loss of the vestibular function results in nausea, vomiting, vertigo and loss of craving for life. The purpose of this study is to develop a off-vertical rotatory system for evaluating the function of semicircular canals and otolith organs, selectively, and visual stimulation system for- stimulation with horizontal, vortical and 3D patterns. The Off-vortical axis rotator is composed of a comportable chair, a DC servo-motor with reducer and a tilting table controlled by PMSM. And a double feedback loop system containing a velocity feedback loop and a position feedback loop is applied to the servo controlled rotatory chair system. Horizontal, vertical, and 3D patterns of the visual stimulation for applying head mounted display are developed. And wireless portable systems for optokinetic stimulation and recording system of the eye movement is also constructed. The gain, phase, and symmetry is obtained from analysis of the eye movement induced by vestibular and visual stimulation. Detailed data were described.

  • A control of the body posture and movement is maintained by the vestibular system, vision, and proprioceptors. Especially, vestibular system has a very important function that controls the eye movement through vestibuloocular reflex and contraction of skeletal muscles through vestibulospinal reflex. However, postural disturbance caused by loss of vestibular function results in nausea, vomiting, vertigo and loss of craving for life. Lose of vestibular function leads to abnormal reflex of eye movements named nystagmus. Analysis of the nystagmus is needed to diagnose the vertigo, which is performed by means of electrooculography(EOG). The purpose of this study is to develop a computerized system for data processing and an algorithm for the automatic evaluation of the slow component velocity(SCV) of nystagmus induced by optokinetic(OKN) stimulation system. A new algorithm using recursive least square method(RLSM) to detect SCV of nystagmus is suggested in this paper. This method allows a fast and precise evaluation of the nystagmus, through artifact rejection techniques. The results are depicted in this paper.
