Purpose: The purpose of this study was to examine the perceptions regarding the use of Emergency Contraceptive Pills (ECPs) among young Korean women. Method: The study included 14 unmarried women aged 19 to 34 years (mean, 25 years). Data was collected by focus group interviews and an in-depth interview from July to November, 2005. Content analysis was conducted. Result: The four major themes that emerged were control of accessibility, safety concern, lack of knowledge and information, and ambivalence. Control of accessibility: Most of the participants stated a prescription is necessary although they might feel ashamed if they had to ask for an ECP. Safety concerns: Participants thought that taking an ECP would be harmful to their body. Lack of knowledge and information: Most of the participants felt that they did not know enough about ECPs and were willing to learn more. Ambivalence: The participants stated that they would take an ECP when needed and would recommend it to a friend although they were concerned about the risks of ECPs. Conclusion: The results from this study suggest the need for an educational and awareness program to empower women to be able to make informed decisions on ECPs when needed.

The main purpose of this squib is to provide a new principled account for variation of canonical sentence structure in Korean and Japanese based on the linguistic data commonly observed in some dialects of Korean and Japanese. Unlike the English case in which Comp(lementizer) such as 'that' in an embedded clause freely drops as far as the ECP (Lasnik & Saito 1992) is obeyed, some dialects of both Korean and Japanese show interesting linguistic data very different from those of English, thereby leading us to reasonably doubt the traditionally-accepted paradigm of the canonical sentence structure of CP for all languages. In this squib I propose, based on Korean & Japanese dialects and by developing the Minimal Structure Principle (MSP) ($Bo{\check{s}}kovi{\acute{c}}$ 1997, p. 25), that the cannonical structure of a sentence is not fixed, from the beginning at all, to be one single maximal category, CP. Instead, it should be decided to be either CP or IP, based on the feature of [${\pm}$markedness] and MSP, and the marked (or non-cannonical) embedded sentence needs to satisfy ECP for adjacency (or feature-licensing by the matrix verb in the MP terminology).

This research was conducted in the laboratory to investigate an alternative of Copper(Cu) removal from an heavymetal wastewater using the electrochemical precipitation(ECP) process. The ECP unit consisted of an electrolytic cell made of Titanium plate and Steel plate representing anode and cathode. The DC power source applied to the ECP unit had electrical potential(E) of 50$\pm$ 1V, respectively. The synthetic wastewater used in the experiments contained Cu in the 10 mg/l concentration and the electrode separation were 2, 3, 4 cm and the initial pH were 3, 6, 9, 12, and electrolytic concentration were 0.005, 0.0125, 0.025, 0.0375 mole, and the real heavymetal wastewater used in the experiments. From the experiment for removal efficiency according to pH variation, the low pH area doesn't give the coagulation effect by Ti(OH)$_4$ because process interfere with the coagulation and oxidation reaction, therefore the optimum pH was 4-7. The removal rate was 97.75% after the lapse of 30 minutes when copper concentration and electrolytic concentration were respectively 10 mg/l and 0.025 mole. The removal rate was 96.41% after the lapse of 30minutes when the real heavymetal wastewater used. The optimum consumption of power showed 27KWh/m$^3$ when copper concentration, electrolyte concentration and cell potential were respectively 10 mg/l, 0.025 mole and 50$\pm$ 1 Volt.

Recently, various security threats such as data leakage and data forgery have been possible in the communication and storage of data shared in the cloud environment. This paper conducted a study on the CP-ABSC scheme to solve these security threats. In the existing CP-ABSC scheme, if the data is obtained by the unsigncryption of the data user incorrectly, the identity of the data owner who uploaded the ciphertext cannot be known. Also, when verifying the leaked secret key, the identity information of the data user who leaked the secret key cannot be known. In terms of efficiency, the number of attributes can affect the ciphertext. In addition, a large amount of computation is required for the user to unsigncrypt the ciphertext. In this paper, we propose ECP-ABSC that provides data user traceability, and use it in a cloud environment to provide an efficient and secure data sharing scheme. The proposed ECP-ABSC scheme can trace and verify the identity of the data owner who uploaded the ciphertext incorrectly and the data user who leaked the secret key for the first time. In addition, the ciphertext of a constant size is output and the efficiency of the user's unsigncryption computation were improved.

Background : Airway inflammation and hyperresponsiveness are recognized as major characteristics of bronchial asthma. Airway inflammation has usually been assessed by invasive methods, e.g. BAL or bronchial biopsy, but recent studies proposed induced sputum as another reliable and non-invasive tool to investigate airway inflammation in asthmatic patients. Thus, the relationship between airway inflammation assessed by induced sputum and airway hyperresponsiveness was investigated in asthmatic patient. Method : Airway responsiveness was determined by the concentration that caused a 20% decrease in $FEV_1$($PC_{20}$) after inhaling incremental concentrations of methacholine. The numbers of inflammatory cells and the concentration of eosinophilic cationic protein(ECP) were assessed in induced sputum obtained by inhalation of hypertonic saline(3%). Result: We analyzed sputum induced in 15 stable asthmatic patients. The differential cell count(%) of macrophages, neutrophils, eosinophils and lymphocytes in induced sputum were $39.1{\pm}27.0%$, $29.6{\pm}21.0%$, $28.8{\pm}18.8%$, $1.3{\pm}3.1%$ respectively. The mean value of baseline FEV1(predicted) and ECP were $76.3{\pm}30.3%$ and $1,101{\pm}833{\mu}g/L$ respectively. The geometric mean value of $PC_{20}$ was 0.56 mg/mL. The relationships between the sputum eosinophil and ECP in induced sputum, and between sputum eosinophil and degree of airway responsiveness($PC_{20}$) were found to be significantly correlated (r=0.81, p<0.05 and r=-0.78, p<0.05, respectively). Sputum neutrophils and $PC_{20}$ were not correlated to each other (r=0.11, p=0.69) and a significant negative correlation was found between ECP and baseline $FEV_1$(predicted)(r=-0.62, p<0.05). Conclusion : The results of this study suggest that an induced sputum via a inhalation of hypertonic saline is useful to determine a patient's status of airway inflammation, and airway inflammation is one of the major causal factors in the development of bronchial hyperresponsiveness in asthmatic patients.
