In this paper, a P2P Standard Group Formation (P2P-SGF) method in Wi-Fi Direct is presented to provide direct communication services between Internet-of-Things (IoT) gateways. Generally, network traffic congestion and speed reduction problems are caused when transmitting mass data as well as measured data from many sensors between IoT gateways via an Access Point (AP). For solving these problems, it is required to implement Wi-Fi Direct efficiently transmitting mass data between IoT gateways without passing through the AP. The implemented P2P-SGF method basically performs Discovery, GO (Group Owner) Negotiation, WPS (Wi-Fi Protected Setup) Provisioning, and Address Configuration. Especially, it supports the DLNA (Digital Living Network Alliance) service function for sharing mass data between IoT gateways. Some experimental results verify that it can successfully share large video files.

Recently since urbanization has brought about a dried stream and a worse water quality, Anyang city discharged the third treated sewage into the upper stream of Anyancheon and Hakuicheon. As the result, Hakuicheon had the water level and velocity enough for a living thing in the water to live in but water quality was worse than it had been. Therefore in case of meeting the water level and velocity of the second grade water-quality which living things in the water can live in, the discharge and water quality to secure in-stream flow must be at least 0.350 $m^3/s$ and $BOD_5\;3.2 mg/{\iota}$ respectively. In Anyancheon the water level was increased a little higher than it had been but the velocity was almost unchanged in comparison with it before. On the other hand the water quality was a little better than it had been. Therefore in case of meeting the water level and velocity of the third grade water-quality that people can do water-friendly activity, the discharge and water quality to secure in-stream flow must be at least 0.688 $m^3/s$ and $BOD_5\;4.8 mg/{\iota}$ respectively. The water-quality prediction on the suggested eight scenarios was simulated in all satisfying the third grade water-quality.

Purpose: The purpose of this study was to identify and describe phenomenological structures of the lived experience of struggling against an illness for patients with Amyotrophic Lateral Sclerosis (ALS). Methods: The participants were 7 patients with ALS recruited by snowball sampling who agreed to participate in this research and could verbally communicated with the researcher. Data were collected by long term-repeated interviews with participants in their own homes. Data were analyzed using Colaizzi's method of phenomenology. Results: Four categories were extracted as follows: 'Being seized with fear of death', 'Living a marginal life', 'Accepting hard fate', and 'Clinging to faint life'. Seven theme clusters were identified as: 'Wandering to find a healing method with ominous signs in the body', 'Having a diagnosis of ALS is like a bolt from the blue and struggling against illness with faint hope', 'Being forced out to the edge of life with anguish', 'Filling one's heart with hatred and longing toward becoming estranged from the world', 'Living with stigma as a stumbling block with bitter grief in one's heart', 'Accepting every things as one's fate with self controlled fear of death', and 'Attaching to desire to live'. Conclusion: The results of this study can be used to develop the programs to support patients with ALS and their family.
