Background and Objectives : The purpose of the present study is to investigate the effect of vocal hygiene education for the female elementary school teachers. Materials and Method : Thirty healthy female elementary school teachers were enrolled for the study. We provided a vocal hygiene education to the half of them. Voice handicap index and acoustic parameters were measured before and 4 week after the education. The efficacy of vocal hygiene education was analyzed by Wilcoxon Signed-rank test. Results : The vocal hygiene group showed significant improvement both in the subjective and objective data after the education. However, the non-vocal hygiene group failed to show any improvement. In functional score, emotional score, jitter, shimmer, only Junior Class(JC) could find significant after the education. Only low career(LC) could find significant in subjective data. Conclusion : Vocal hygiene education may be useful in reducing vocal misuse and abuse associated with teaching, and can be an effective method to maintain and improve the vocal health of teachers.

To understand the present states of abstracting and to investigate contents of abstracts, a survey content analysis was done in the field sciences. Of the 102 nation wide scholarly journals examined $54(53\%)$ included abstracts with articles. 33 had abstracts in Korea Among the 34 journals with editorial statements about abstracting only 13 had suggestions about abstract contents. Based on the investigation, 4 disciplines having abstracts mostly was selected and 149 abstracts in the 4 major journals in each discipline were sampled. Complete abstracts were ama;uzed according to 12 variables covering required content elements, unnecessary statements, and writing styles. Statistical characteristics of the abstracts is varied among disciplines and the scope is very wide. Particularly number of paragraph and number of character per abstract is much different from the standards. The content analysis showed $51\%$ of the abstracts were incomplete. $39\%$ of the abstracts did not mention research method used. 59 abstracts included unnecessary statements. Writing stle analysis also showed many faults both in the pronoun abuse and the misuse of voice or tense. Korean author abstracts in social science scholarly journals have deficiencies in linguistic structures as well as in contents and style.

Traditionally, postal services that produce and deliver paper-based notices have been the mainstream. The reason is that it has the function of distribution and proof of delivery in the postal delivery system as well as the advantage of information delivery through postal delivery. After all, for the purpose of distribution and proof of delivery, many organizations use paper-based postal notices. However, in recent years, it has been in the spotlight to produce a paper-based postal notice as an electronic notice and deliver information to a mobile device through the Internet. In this paper, we propose a safe interworking method for user identification information required for private institutions to transmit mobile electronic notices. In order for a private institution to accurately deliver an electronic notice to a mobile service subscriber, a means to confirm whether the private institution and the mobile device subscriber are the same person is required. In the mobile electronic notification service, the connecting information provided by the personal identity proofing agency is used as a means of user identification. Connecting information is called a resident registration number on the Internet and is one-way hash information that can only be created by the personal identity proofing agency designated by the government. In order to transmit a mobile electronic notice, it is necessary to share connecting information for the same user identification between the institution that requests the sending of the electronic notice and the institution that processes the sending of the electronic notice. Connecting information is personal information that can uniquely identify a user, and if it is disclosed, damage such as personal information infringement may occur. As such, it is necessary to prevent problems that may arise from misuse and abuse of connecting information as well as increase in the benefits of sending the mobile electronic notice. In this paper, a safe and effective mobile electronic notification service can be performed by suggesting a method for safe interworking of information related to the mobile electronic notification service.

Because of the airtightness of building, misuse of building materials and abuse of furniture, indoor air pollution problems have been increasingly concerned especially with apartment buildings. To improve the IAQ(Indoor Air Quality) in apartment building, this study was aimed at analyzing the factor of interior building material and furniture and calculating the ventilation rate of living room and bed room according to the surface area of interior building material and furniture in terms of VOCs(Volatile Organic Compounds) and HCHO(Formaldehyde). The results of this study are as follows; 1) In the concerned rooms, the living room has less pollution emission rate L(surface area/volume) than that of the bed room but, the living room needs more ventilation rate than that of the bed room because of built-in furniture in terms of VOCs and HCHO. 2) Built-in interior furniture is very important factor in IAQ problems of apartment building, but until now there is no provision about the built-in furniture, so that the provision must be regulated to control the IAQ. 3) To control the IAQ problem, the effective ventilation plans must be established according to the required ventilation rate by means of natural or mechanical ventilation method.

The trial and success of malicious cyber attacks has been increased rapidly with spreading of Internet and the activation of a internet shopping mall and the supply of an online, or an offline internet, so it is expected to make a problem more and more. The goal of intrusion detection is to identify unauthorized use, misuse, and abuse of computer systems by both system insiders and external penetrators in real time. In fact, the general security system based on Internet couldn't cope with the attack properly, if ever. other regular systems have depended on common vaccine softwares to cope with the attack. But in this paper, we will use the positive selection and negative selection mechanism of T-cell, which is the biologically distributed autonomous system, to develop the self/nonself recognition algorithm and AIS (Artificial Immune System) that is easy to be concrete on the artificial system. For making it come true, we will apply AIS to the network environment, which is a computer security system.

The purpose of this study was to explore the direction in applying platform business model to the site to facilitate the growth of a private security guard service according to the development phase of economy, The directions of platform business application to be suggested through the study method are as follows. First, ensuring publicness. It should be able to integrate the government's and private sector's ability to collect and impart information. Second, securing self-regulation. Self-regulation should be guaranteed in the limit not to abuse or misuse others' information in re-producing and using information on private safe management and public order. Third, ensuring access. Past safety management has been controlled by public order power such as nation, military and police power, but access should be made to be convenient between suppliers and demanders. Fourth, securing profitability. In conclusion, those supplying and consuming private security guard service should be able to get their wanted value and share economic profits.

Vocal process granuloma can occur commonly by laryngopharyngeal reflux (LPR), vocal abuse or misuse. It has been reported that voice therapy is employed with medication therapy for the patients who has vocal process granuloma, however research about effect of voice therapy can be hardly founded. For that matter, the primary aim of this study was to evaluate the effect of therapeutic method we implement. Thirty one patients who has been diagnosed with vocal process granuloma from January, 2007 to June, 2009 participated in this study. 19 patients among them are provided voice therapy and medication, 12 patients take only medication. Voice therapy is implemented ranging from 5 to 19 sessions (mean: 8.6 sessions). We provided explanation about problem each patient has, voice rest, SKMVTT$^{(R)}$, abdominal breathing, and relaxation in session. All subjects were examined by videostroboscopy, perceptual assessment, acoustic and aerodynamic measures. Consequantly, the greater part of the patients (78.9%) who is treated by voice therapy and medication are confirmed disappearance or decrease of granuloma, it shows better results compared with the group provided only medication (66.7%). Especially, the period of drug administration is 3.7 months in the group runs parallel with voice therapy, the period of other group is 7.8 months. The results of acoustic and aerodynamic measures after treating indicates there are significant decrease in Jitter, Shimmer, and NHR, and increase in MPT, Psub (p<.05). However, there is no large difference statistically even though voice quality has improved since the therapy. In conclusion, it is verified that the voice therapy to the vocal process granuloma patients taking medication is effectual method, we recommend combining voice therapy with medication when treatment is needed for the vocal process granuloma patients.

As the range of professional voice users are expanding, interest towards voice increases as well. Especially as teachers compose the occupational group, exposed to high risk of voice disorder, it is necessary to identify the cause of speech problems and speech disorders. The purpose of this study is to analyze the voice characteristics of teachers and to investigate the causes of voice disorders. From 2000 to 2018, 414 studies were found under a combinated set search words of 'profession', 'Teacher', 'Professional Voice User', 'Voice', 'Voice disorders', 'Risk' and out of them, 8 studies were selected as final focus analysis subjects. The qualitative evaluation was carried out by modifying the Quality: checklist for assessing the Risk of bias. The study confirmed that voice misuse frequently occurred to teachers when they used their voice and this feature was affected by the environment. These results suggest that environment improvement of teachers' speech abuse and consistent voice education are necessary.

Nicotine poisoning arising from the use of nicotine patches is rare. However, because nicotine patches are classified as an OTC drug, the risk of misuse or abuse is increasing. Nicotine poisoning using nicotine patches shows an unusual clinical presentation compared to that from oral ingestion of multiple doses of nicotine. We present a case of misused nicotine patches that cause a nicotine poisoning. A thirty-nine year-old healthy man visited the ER with complaints of an intermittent cramping abdominal pain with nausea and vomiting. Upon physical examination, there were no specific findings except increased bowel sounds, and the patient's initial laboratory findings were also unremarkable except for an increased bilirubin level. CT revealed a mild degree of fatty liver. The patient's symptoms did not improve any further with conservative management. During his ED stay, we meticulously took his history again, and we discovered that he had used nicotine patches for three days, six days before admission, and had misused the nicotine patches as NSAID patches. The patient's diagnosis of nicotine poisoning was confirmed by a urine cotinine level ten times the normal value. After a 12-hour stay in the ED, his symptoms disappeared without any specific management.
