As the E-commerce and E-business are developed actively, using certificate is incremented rapidly. The certificate validation must be confirmed at first in E-commerce and the OCSP Responder can offer CSI to the client using OCSP. With the rapid development of the E-commerce based on the Internet, a lot of clients request CSI to OCSP Responder. So, the load to OCSP Responder is increased and the OCSP Responder may be overloaded. Therefore, for distributing the load to an OCSP Responder, D-OCSP is introduced. As the CRL has a lot of information about revoked certificates and have a high exposure Possibility of information in the process of distribution, the confidentiality as well as integrity are required in the process of distribution. So, we propose a CRL distributing method based on group key agreement in D-OCSP. The proposed method can distribute effectively a published CRL to OCSP Responders with confidentiality as well as integrity and offer concurrency that each OCSP Responder can start CSI servicing of new CRL to clients at the same time.

The cerebrospinal fluid tap test (CSFTT) is recommended as a key step in the diagnosis of idiopathic normal pressure hydrocephalus (iNPH). While there is no generally accepted evaluation period for ascertaining a CSFTT responder, a substantial number of patients are evaluated only once within 24 hours of the test for improvement in gait. We report an iNPH patient with a favorable response to shunt surgery, who was first judged a non-responder by this standard, though subsequently was judged a responder in virtue of repetitively testing gait over 7 days. A 68-year-old man presented with progressive impairment of gait, balance, and memory. He was diagnosed as iNPH with an Evans' ratio of 0.35. At first hospitalization, change in gait was evaluated 24 hours after the CSFTT. He didn't show any significant improvement and was judged as a non-responder. However, at the second CSFTT, we repetitively tested his change in gait over seven days. Forty-eight hours after the tap, he showed significant improvement in his gait. He was then confirmed as a responder. After the operation, the gait difficulties were almost fully resolved. Further studies developing the standard procedure of the CSFTT should be considered.

As investigations dealing with digital evidence increase, so to does the need for skilled first responders and improved investigation process models. Recently the concept of digital forensic triage and preliminary analysis has been gaining popularity in investigation laboratories. At the same time, however, there has been little focus on specific training needs of first response and preliminary analysts. Instead, many organizations consider these responders to need the same skills as full digital forensic analysts. In this work we describe the 'ideal' digital investigation first responder and preliminary analyst, hardware and software requirements and most importantly, required training.

In Taiwanese Daoism, the Celestial Worthy of the Ninth Heaven, Responder, Thunderbolt-bearer, and Transformer of the Universe (九天應元雷聲普化天尊) is the highest deity in the Thunder Ministry. In the the Korean new religion, Daesoon Jinrihoe (大巡真理會), he is the Supreme God. However, since the Celestial Worthy of the Ninth Heaven, Responder, Thunderbolt-bearer, and Transformer of the Universe has the same name in these two traditions, it naturally leads people to wonder whether or not they can be considered the same deity. Or failing that, it could still be asked, to what extent are these two deities related? Or it could further be asked what meaning does the Celestial Worthy of the Ninth Heaven, Responder, Thunderbolt-bearer, and Transformer of the Universe have in these two religions? Anyhow, all such questions depend on first establishing a greater degree of basic clarity. Religious scripture can serve as a cornerstone in gaining such basic clarity. Scripture almost invariably contains information regarding the divine nature, divine authority, and sacrosanctity of deities reflective of what is understood by the devotees of those religions. Clues on the precise nature of these key attributes of deity-depiction can be drawn out of scriptural accounts, and as such, the research presented in this paper will begin by comparing two relevant scriptures. The representative scriptures highlighted in this paper will be The Canonical Scripture (典經) of Daesoon Jinrihoe and The Scripture of the Jade Pivot (玉樞寶經) of Zhengyi (Orthodox Unity, 正一) Daoism. These scriptures will serve as the basis for exploration and analysis of the divine attributes of the Celestial Worthy of the Ninth Heaven, Responder, Thunderbolt-bearer, and Transformer of the Universe in terms of his divine nature, divine authority, and sacrosanctity. By comparing these two scriptural accounts of his divine attributes, the similarities and differences that arise can be properly explored. This paper endeavors to clarify the ultimate purpose of 'the Celestial Worthy of the Ninth Heaven, Responder, Thunderbolt-bearer, and Transformer of the Universe.' In this paper, the first step will be an exploration of scriptural analysis. The contents of this paper is roughly divided into four sections. The first section is an exploration of the general contents of the two scriptures, including their origin, contents, and value. The second section focuses on the three main divine attributes of the Celestial Worthy of the Ninth Heaven, Responder, Thunderbolt-bearer, and Transformer of the Universe: his divine nature, divine authority, and sacrosanctity. The third section will compare the depictions of the deity in the two scriptural accounts in terms of those three attributes. Lastly, the deity's evolutionary history in both religions is shown and compared and final remarks are made on the contemporary value of the Celestial Worthy of the Ninth Heaven, Responder, Thunderbolt-bearer, and Transformer of the Universe.

Purpose: The first responder's role during a cardiac arrest scene is to initiate CPR. The AHA has recognized and included the first responder's role for improving the survival rate of cardiac arrest patients. Health personnel working in nursing, emergency care, dental hygiene, radiology, and ocular optics frequently confront sudden cardiac arrest while working. This study was to identify the relationship between the educational experience and recognition with the level of knowledge about CPR for college students. Method: Five hundred forty college students enrolled in the department of nursing science, radiological technology, ocular optics, emergency medical technician, or dental hygiene in Daejeon city were surveyed. The tool used was CPR knowledge developed by the authors based on a literature review including 2005 AHA's CPR guideline. Result: The higher educational experience of CPR was, the higher the level of knowledge. The knowledge of the students in nursing or emergency medical technician was higher than students in dental hygiene, radiology, and ocular optics. Conclusion: CPR class should be included in the curriculum for college students in order to improve their accuracy as a first responder to cardiac arresting patients.

Background: As herpes zoster progresses via postherpetic neuralgia (PHN) to well-established PHN, it presents its recalcitrant nature to the treatment. At this point, the well-established PHN is fixed as a non-treatable, but manageable chronic painful neuropathic disorder. This study evaluated the incidence of complete relief from PHN according to PHN duration at their first visit, and the other factors influencing it. Methods: A retrospective chart review was performed on patients with PHN at a university-based pain clinic over 7 years. The responders were defined as patients who had complete relief from pain after 1 year of active treatment. Age, sex, PHN duration at their first visit, dermatomal distribution, and underlying disorders were compared in the responder and non-responder groups. Responders were also compared according to these factors. Results: Among 117 PHN patients (M/F = 48/69), 35 patients (29.9%) had complete relief from PHN. Mean ages were $64.3{\pm}10.6$ and $66.9{\pm}10.7$ years, numbers of male to female patients were 11/24 and 37/45, and mean durations of PHN at their first visit were $8.5{\pm}6.3$ and $15.3{\pm}10.7$ months in the responder and non- responder groups, respectively. In addition, PHN patients who visited the clinic before 9 months showed a better result. Dermatomal distribution and underlying disorders did not show significant differences. Conclusions: Almost 30% of PHN patients received complete relief. Those who sought treatment in a pain clinic before 9 months received a better result.

The registration rate of eco-friendly vehicles, such as hydrogen vehicles, is increasing rapidly, however, few first responders have experienced related accidents. Accident scenarios at hydrogen refueling stations and hydrogen vehicles on a road were investigated, and the relative importance of each scenario was analyzed using AHP analysis. Leakage, jet flame, and explosion that occurred inside and outside the hydrogen refueling station were reviewed, and the hydrogen gas explosion in the compartment showed the highest importance value. In case of the hydrogen vehicle, traffic accident statistics and actual accidents were used. It was analyzed that the hydrogen vessel explosion on the road due to the failure of TPRD and the leakage in the underground parking area were difficult to respond. The developed accident scenarios are expected to be used for first responder training.

Purpose: To compare and analyze current state of domestic and foreign educational program to develop a program and provide basic information for qualitative improvement of the program. Method: Referred to records and used various methods as searching on the Internet. Analyzing methods and standards are as follow : 1) As for the current status of domestic educational program, find out about organizations that conduct the program 2) As for the current status of foreign program, find out about United States, Canada and United Kingdom. 3) As for comparison and analysis, find out about curriculum, subject, the number of people, content, cost and time. Results: In comparison and analysis of subjects and program, United States, Canada and U. K. specified the subjects according to occupations to offer various programs appropriate for special occupational situations whereas domestic program only provide education of CPR and usage of AED. Foreign countries provide sufficient time from 5.5 to 40 hours according to occupations. In contrast, Korea only provide 2-4 hours of educations, which is insufficient to master techniques of first aid. In addition, foreign countries precisely regulate organizations that fulfill the qualification and specific guidelines for content of education. However, Korea doesn't have any standards of qualification or guidelines. Discussion: It is necessary to specify first aid education according to occupations to provide diverse programs. Furthermore, it is necessary to establish nationwide regulations for subjects and content of the programs of the first responder.

Background and Objectives: Radioactive iodine therapy (RAI) is an important treatment modality of Graves' disease (GD), but there is still not a consensus on the optimal dosage regimen. We studied the treatment success rate of different RAI doses, and examined which clinical markers were useful for determining the optimal RAI dosage for successful therapy in Korean patients. Materials and Methods: We retrospectively studied 123 patients with GD treated with RAI between 2004 and 2014 at Chonnam National University Hwasun Hospital. The responder group was defined as patients who developed hypothyroidism requiring levothyroxine replacement following RAI, regardless of the RAI dosage. Results: A total of 54 patients (43.9%) became hypothyroid after the first dose, and 31 needed two to four additional doses to achieve hypothyroidism. In the responder group as a whole (85 patients), the mean total dose of RAI was $15.5{\pm}7.0mCi$ and the mean thyroid volume (TV) was $35.4{\pm}23.4mL$. When divided into low dose (<15 mCi, n=46) and high dose (${\geq}15mCi$, n=39) responder groups, TV was significantly lower in the low-dose responder group ($25.7{\pm}11.4$ vs. $48.4{\pm}31.3$, p<0.001). The optimal cut-off TV for the low-dose responder group was <32.37 mL (sensitivity 80.9%, specificity 76.7%). Conclusion: TV had significant effects on the outcome of RAI in GD patients. The optimal fixed RAI dose for Korean GD patients with a large goiter (${\geq}33mL$) should be at least 15 mCi to achieve the best outcome.

Purpose: This is the descriptive research for providing the basic data necessary for the first aid education after understanding the first aid experience, first aid education, first aid knowledge, and educational needs of ski resorts workers. Methods: 323 workers of domestic 9 ski resorts were surveyed for data, which was collected using the systematic questionnaire from Oct. $6^{th}$ to $20^{th}$, 2011. The collected data has been processed using the program of SPSS Win. Version 14.0 and analyzed that according to the purpose of research in terms of real number, percentage, standard deviation, t-test and ANOVA. Results: 1. 58.8%(190) of ski resort workers experienced an emergency on duty and 33.6%(108) carried out the first aid for emergency patients on duty. 2. 65.6%(210) of workers experienced first aid education. 3. The percentage of correct answers of first aid knowledge was average 46.8% and average $9.35{\pm}2.54$ points out of total 20 points. 4. The first aid educational necessity indicated as follows: ski resort workers need first aid education (97.5%, 306); workers want to have the education if they have chance (94.6%, 296 persons); in addition, they need the repeated education of first aid (95.6%, 301). Conclusion: It is understood that as special first aid service can be delayed in ski resorts due to their geographical characteristics, the workers of ski resorts need the continuous and systematic first aid education enabling them to play the first responder in the first aid system when emergency situation occurs.
