  • This study investigated the factors affecting problematic drinking amongst the male university students of the Changwon area (n=367). The participants were divided into 3 groups, and undertook the self-report questionnaire survey. Based on the AUDIT (Alcohol Use Disorders Identification Test) guidelines, problematic drinking were rated as 'no problem' (28.8%), 'at-risk drinking' (41.7%), and 'alcohol abuse' (29.5%). Our study revealed that students living alone, indulged in more club activities, and drank more than 3 cans of carbonated drinks a day; this was significantly high on the AUDIT score (p<0.05). Participation in education was significantly higher (p<0.05), but intention to reduce the monthly alcohol consumption was significantly lower (p<0.001) in the alcohol abuse group. Recognition level of drinking cultures, drinking habits, AUDIT, and nicotine dependence were significantly higher in the alcohol abuse group (p<0.001). Recognition level of drinking cultures and nicotine dependence by the FTND (Fagerstrom Test for Nicotine Dependence) positively correlated with problematic drinking, whereas dietary guidelines and self-esteem showed a negative correlation with problematic drinking (p<0.05). Based on the results of multiple linear regression analysis, the factors affecting problematic drinking were recognition level of drinking cultures (${\beta}=0.47$, p<0.001) and nicotine dependence (${\beta}=0.23$, p<0.001). We conclude that implementation of health education for university students, would aid in rectifying the incorrect perception of drinking. Furthermore, both drinking and smoking should be considered simultaneously.

  • Purpose: This study aimed to identify factors influencing nicotine dependence among male college students intending to quit smoking on the basis of the PRECEDE model. Methods: A cross-sectional survey of smokers, enrolled at the Smoking Cessation Support Center in W city in Korea was conducted between September 2015 and December 2016. Data was analyzed using the SPSS program for descriptive statistics, bivariate analyses, and hierarchical multiple regression. Results: The mean score of nicotine dependence was determined to be 2.9. Tobacco craving (β =.34, p<.001), social smoking (β =-.23, p=.004), allowance (β =.22, p=.010) and age of smoking initiation (β =-.20, p=.022) were factors that predicted nicotine dependence of male college students. The final model explained 28.3% of the variation in nicotine dependence (adjusted R2=.28), and was significant (F=7.22, p<.001). Conclusions: We determined that to support smoking cessation, it is necessary to develop anti-smoking programs that consider the social and cultural factors of male college students as well as their personal psychological characteristics.

  • Objectives:The purpose of this study is to evaluate the pathophysiology of alcoholics by investigating the differences in frequency of Aldehyde Dehydrogenase 2(ALDH2) genotypes and ALDH2 alleles between patients with alcohol dependence and controls, and the differences of drinking and personality traits in Korean male alcoholics with ALDH2 genotype variances. Methods:The authors selected 98 patients with alcohol dependence and 53 controls. Self-report questionnaires for acute reponses after alcohol ingestion, the AUI(Alcohol Use Inventory), and the NEO-PI-R(NEO Personality Inventory Revised) were given to all patients with alcohol dependence. ALDH2 genotypes were typed with MboII RFLP(Restriction Fragment Length Polymorphism) method in 53 controls and 98 patients with alcohol dependence. The authors divided alcoholic patients into two groups according to the presence of variant $ALDH2^2$ allele;normal ALDH2 alcoholics(N=87) and variant ALDH2 alcoholics(N=11). Results:1) The genotypic frequencies of subjects with $ALDH2^{1/1}$ were higher and those with $ALDH2^{1/2}$ and $ALDH2^{2/2}$ were lower in patients than in controls. 2) Alcohol dependence could be found in $ALDH2^{2/2}$ homozygote individuals. 3) Variant ALDH2 alcoholics had more family problems in the AUI than normal ALDH2 alcoholics. 4) Variant ALDH2 alcoholics experienced more flushing and cardiovascular responses after alcohol ingestion than normal ALDH2 alcoholics. 5) Variant ALDH2 alcoholics had less altruistic personality traits in the NEO-PI-R than normal ALDH2 alcoholics. 6) Variant ALDH2 alcoholics tended to have more tolerance to alcohol than normal ALDH2 alcoholics. Conclusion:Variant $ALDH2^2$ allele might play a protective role in the pathogenesis of alcohol dependence and there were several significant differences of drinking and personality traits in Korean male alcoholics with ALDH2 genotype variances.

  • Tapentadol is a novel oral analgesic with a dual mode of action as an agonist of the ${\mu}$-opioid receptor (MOR), and as a norepinephrine reuptake inhibitor (NRI) all in a single molecule. Immediate release (IR) tapentadol shows its analgesic effect quickly, at around 30 minutes. Its MOR agonistic action produces acute nociceptive pain relief; its role as an NRI brings about chronic neuropathic pain relief. Absorption is rapid, with a mean maximal serum concentration at 1.25-1.5 h after oral intake. It is present primarily in the form of conjugated metabolites after glucuronidation, and excretes rapidly and completely via the kidneys. The most common adverse reactions are nausea, dizziness, vomiting, and somnolence. Constipation is more common in use of the ER formulation. Precautions against concomitant use of central nervous system depressants, including sedatives, hypnotics, tranquilizers, general anesthetics, phenothiazines, other opioids, and alcohol, or use of tapentadol within 14 days of the cessation of monoamine oxidase inhibitors, are advised. The safety and efficacy have not been established for use during pregnancy, labor, and delivery, or for nursing mothers, pediatric patients less than 18 years of age, and cases of severe renal impairment and severe hepatic impairment. The major concerns for tapentadol are abuse, addiction, seeking behavior, withdrawal, and physical dependence. The presumed problem for use of tapentadol is to control the ratio of MOR agonist and NRI. In conclusion, tapentadol produces both nociceptive and neuropathic pain relief, but with worries about abuse and dependence.

  • 본 논문은 경주국립공원 내 사찰숲길 이용자의 장소애착이 환경요인에 대한 인식과는 어떠한 구조적 관계를 형성하고 있는 지를 구조방정식모형을 활용하여 탐색하며, 국립공원 관리에 있어서 경관선호 보다는 경관애착에 근거한 보전적 측면에서의 정책적 함의를 제공하는데 있다. 경주국립공원 내 대표적인 사찰인 불국사를 찾는 탐방객을 대상으로 설문조사를 실시한 후, 수집된 자료를 분석하여 구조방정식모형을 도출하였다. 연구 결과, 장소의존성은 장소애착에 대하여 유의하게 긍정적으로 영향을 미치는 것으로 나타난 반면, 장소정체성은 장소애착에 대하여 통계적으로 유의한 영향을 나타내지는 않는 것으로 나타났다. 장소의존성이 보다 장소애착에 영향을 미치는 것으로 나타났다(경로계수=0.55). 장소애착은 환경요인의 중요성에 대한 인식에 있어서 경관이용과 시설이용 모두 유의하게 정(+)의 방향으로 영향을 미치는 것으로 나타났다. 장소애착은 사찰숲길 이용의 중요성에 있어서 시설요인 보다는 경관요인에 대하여 보다 강한 영향력을 보이는 것으로 나타났다(경로계수=1.01). 이러한 결과는 국립공원의 경관자원의 중요성을 다시 확인시키며, 이로부터 사찰숲길 경관의 보전에 중점을 둔 관리방안이 마련되어야 할 것으로 판단된다.

  • Objectives: This study furthers the currents understanding of alcohol use disorders, stress, mental health status and suicide among Seoul citizens. This study is to identify differences according to socio-demographic variables and variables which affect stress, mental status and suicide for developing mental health programs. Methods: The study subjects using cluster-stratified sampling method were 1234 adults over 19 years old from 17 dong, S-Ku in Seoul City. A cross-sectional study with face-to-face interview was used to collect data. A questionnaire measuring socio-demographic variables, Symptom Checklist-90-Revised (SCL-90-R) and psychosocial wellbeing index-short form (PWI-SF) was utilized. Results: Three findings in this study were discussed: (1) The prevalence of problem drinking and alcohol dependence and AUDIT score were significantly higher among male, younger age, and high level of education and income; (2) AUDIT score were related with stress, all 9 symptoms of SCL-R and suicide plan; (3) Problem drinkers were more likely to have 2.5 times of anxiety, 3.0 times of hostility, and 2.4 times psychoticism than non alcohol problem drinkers. Alcohol dependence drinkers were more likely to have 1.9 times of high risk group of stress, 4.1 times of obsessive-compulsive, 4.7 times of anxiety, 5.5 times of hostility, and 2.3 times psychoticism than non alcohol dependence drinkers. Conclusion: The findings suggest that the future intervention of Mental Health programs should be carefully designed and tailored by socio-demographic variables.

  • Yoon et $al.^1$ presented an approximate mathmatical model to describe ammonia removal from an experimental batch reactor system with gaseous headspace. The development of the model was initially based on assuming instantaneous equilibrium between ammonia in the aqueous and gas phases. In the model, a "saturation factor, $\beta$" was defined as a constant and used to check whether the equilibrium assumption was appropriate. The authors used the trends established by the estimated $\beta$ values to conclude that the equilibrium assumption was not valid. The authors presented valuable experimental results obtained using a carefully designed system and the model used to analyze the results accounted for the following effects: speciation of ammonia between $NH_3$ and $NH^+_4$ as a function of pH; temperature dependence of the reactions constants; and air flow rate. In this article, an alternative model based on the exact solution of the governing mass-balance differential equations was developed and used to describe ammonia removal without relying on the use of the saturation factor. The modified model was also extended to mathematically describe the pH dependence of the ammonia removal rate, in addition to accounting for the speciation of ammonia, temperature dependence of reactions constants, and air flow rate. The modified model was used to extend the analysis of the original experimental data presented by Yoon et $al.^1$ and the results matched the theory in an excellent manner.

  • The imidazopyridine, zolpidem, a non-benzodiazepine hypnotic drug, is widely-prescribed for insomnia. It is regarded as a good alternative to benzodiazepine because of the reduced possibility for abuse and development of dependence. However, more recently, due to the reduced possibility for abuse and development of dependence, it is regarded as a good alternative to benzodiazepine. adverse effects of zolpidem have been recognized. The objective of this report is to provide information on the potential for occurrence of benzodiazepine-like withdrawal seizure in patients who chronically take zolpidem continually. We present and discuss a case of seizure after sudden interruption of the protracted use of an abusively high dose of zolpidem. Zolpidem may not be the ideal drug for longterm pharmacotherapeutic management of insomnia. Clinicians should administer zolpidem at a low-dose for a short period of time for prevention of drug abuse and dependence and the potential for occurrence of benzodiazepine- like withdrawal seizure.

  • We investigated the particularity of temperature and composition changes in $xNa_2O{\cdot}(52.5-x)B_2O_3{\cdot}47.5SiO_2$ glasses by use of FT-IR, $^{11}B$ NMR, Raman spectrometer. From FT-IR and $^{11}B$ NMR spectrometer, we thought that tetrahedral boron, $BO_4$ units are created $N_4$ increasing tendency generated near $600^{\circ}C$. It's expected that composition ana heat treatment directly contributed to structural changes, this changes are following to $Na_2O$ increasing or decreasing. caused by $N_4\;and\;BO_4$ units are caused by relatively increasing or decreasing in the glasses' structure. Particularly, $BO_4$ units are converted to $BO_3$ units after $600^{\circ}C$ heat treatment for 50h in the composition of $x<18(R<0.5,\;R=Na_2O/B_2O_3\;mol\%)$. On the order hand, $BO_3$ units are converted to, $BO_4$ units after $600^{\circ}C$ heat treatment for 50h in the composition of $x{\geq}18\;(R>0.5)$. This particularity of composition and temperature dependence of structural changes are similarly represented by Raman analysis results.
