Opiskelijoiden osallistaminen aktiivisemmiksi toimijoiksi : Pohjois- Karjalan koulutuskuntayhtymä Joensuu Tekniikan yksikkö

Kehittämishankkeeni tavoitteena on saada esille mahdollisuuksia, joiden avulla Pohjois-Karjalan koulutuskuntayhtymän Joensuu Tekniikan yksikön opiskelijat saataisiin aktiivisemmin osallistumaan opiskelijakunnan hallituksen (JOPO) järjestämiin tapahtumiin ja tempauksiin. Yhtenä osa-alueena opinnäytetyöni käsittelee osallisuuden tasoja sekä sosiaalisen vahvistamisen käytänteitä, joiden avulla osallisuus toteutuisi nykytilaa paremmin. Osallisuuteen liittyy vahvasti tieto itseä koskevista asioista, eikä myöskään kokemusta itseä koskeviin vaikutusmahdollisuuksiin voi unohtaa. Ammattialalle opinnäytetyöstä tekee ajankohtaisen se kuinka sosiaalinen vahvistaminen toteutuu ammattiopetuksen arjessa. Opinnäytetyössä käsitellään sosiaalisten vahvistamisen näkökulmaa kehitettäessä toiminnasta opiskelijalähtöistä sekä kuinka opiskelijoiden omaa kansalaisvaikuttamista voitaisiin kehittää innostavuudella. Opinnäytetyötä varten hankitun aineiston avulla JOPO saa tietoa, missä formaateissa Tekniikan yksikön opiskelijat haluavat heitä koskevista tapahtumista tiedotettavan sekä millä tasolla opiskelijoiden tietous on heille järjestetyistä tapahtumista. Opinnäyteyö tarjoaa näkökulmia ja idoita, millä keinoin opiskelijalähtöisyyttä voitaisiin kehittää, että Tekniikan yksikön opiskelijat saataisiin paremmin innostettua ja osallistettua yhteisiin tapahtumiin sekä toimimaan aktiivisempina vaikuttajina omassa oppimisympäristössään. Aineistosta sain selville kuinka tapahtumista tiedottamiseen haluttaisiin kehitystä. Vaikutusmahdollisuuksien koetaan paranevan, jos opiskelijat tietäisivät paremmin, kuinka oppilaitoksessa voi vaikuttaa sekä mitkä asiat vaikuttavat opiskelijoiden aktiivisuutta lisäävästi. Tarkastelen opiskelijalähtöisyyttä vertaistuen, sosiaalisen vahvistamisen käytänteiden, osallisuuden tasojen sekä yhteisötoiminnan kautta. Käsittelen myös opiskelijoiden itsensä vastuuta omasta aktiivisuudesta ja osallisuuteen vaikuttavista näkökulmista.The goal of my development project is to bring out ways to get students of Pohjois-Karjalan koulutuskuntayhtymä Joensuu Tekniikan yksikkö to take part in events organized by the student board (JOPO) more active. This thesis partly covers levels of participation and customs of social empowerment which will improve participation. Participation has to do with knowledge of those matters that involves students. This thesis is topical because of how social empowerment occurs in daily professional training. In thesis I process point of view of social empowerment to make activity more student oriented and how to raise students’ civil activity skills by improving motivation. The material acquired for this thesis will give knowledge to JOPO in which formats the students of technical unit want information of events and how well the students think they have been informed about those events. Thesis also offers point of views and ideas how to improve student oriented approach so that students would be more motivated, participate events more active and work mor e active to effect on their school environment. I found out from the material that students wanted that events should be announced earlier. Students feel that their ways to affect would be better if they knew how they can affect in their school. I examine student oriented approaching by peer supporting, knowledge of social empowerment, levels of participation and co-working. I also reflect students’ responsibility of their own activity and the point of views that effect on participation

水耕栽培によって,生育温度と培地の栄養レベルがカ一ネーションの生育に及ぼす影饗を調査した. ‘レナ’の発根苗を15,20,25,30℃の温度で栽培し,各温度区ごとに栄養レベルを全窒素50-150ppm,りん酸10-60ppm,カリ20-120ppmの範囲とした区を設けた. 結果を要約するとつぎのとうりである. 1.生育温度と栄養レベルは生育に大きく影響した. 生育温度が15℃から20℃の間での好適栄養レベルは全窒素75-125ppm,りん酸30-50ppm,カリ60-120ppmの範囲にあるものと思われた. 2.もっともよい生育を示したのは生育温度を20℃,栄養レベルを全窒素75ppm,りん酸30ppm,カリ60ppmとした区であった. 3.上記の結果とは対照的に,生育温度を30℃とした区においては栄養レベルの生育に及ぼす影響が明らかでなく､茎長や乾物重あるいは肥料の吸収量なども減少した. 4.節数は,生育温度が高いほど増加した

Indoor navigation using Bluetooth Low Energy (BLE) beacons

The popularity of indoor navigation has significantly increased during the last decade. Nowadays, many studies aim to develop new indoor navigation systems and improve the accuracy of the already existing ones. Unfortunately, no definitive method for indoor navigation has been approved yet, which is why this type of systems are not as accessible as those used for outdoor navigation. The purpose of this thesis is to introduce the concept of indoor navigation and demonstrate how common electronic devices can be used to create a simple indoor navigation system. In order to do this, a mobile Android application that helps users navigate inside a building was developed. Signal readings and other information broadcasted by Bluetooth Low Energy (BLE) devices, known as beacons, were used as reference for this application. In addition to this, adapters and sensors integrated into the mobile device were used to track the user’s movement. The application is also capable of providing information to the user related to their location using additional data attachments associated to the beacons. This application is only a prototype meant to provide an idea of how indoor navigation could be possible using no more than a smartphone and few BLE beacons. Even though the system proved to work quite well within the testing area, there are still plenty of aspects that can be improved

Antioxidant Activity of β-Glucan

β-Glucans extracted from barley, which mainly contains β-(1,3-1,4)-D-glucan, are used extensively as supplements and food additives due to their wide biologic activities, including a reduction in blood lipid level. In this study, the antioxidant activity of β-glucan was examined to assess potential new benefits associated with β-glucan, because oxidative stress is considered one of the primary causal factors for various diseases and aging. β-Glucan extracted from barley was found to possess significant antioxidant activity. The amount of antioxidant activity was influenced by different physiologic properties (e.g., structure and molecular size) of β-glucan, which varied depending on the source and extraction method used. The antioxidant activity of β-glucan was significantly higher than that of various polymers that are used as food additives. These results indicate that β-glucan has promise as a polymeric excipient for supplement and food additive with antioxidant and other benefits, which may contribute to enhancing health and beauty

Autonomous mobile robot for outdoor slope using 2D LiDAR with uniaxial gimbal mechanism

The Nakanoshima Challenge is a contest for developing sophisticated navigation systems of robots for collecting garbage in outdoor public spaces. In this study, a robot named Navit(oo)n is designed, and its performance in public spaces such as city parks is evaluated. Navit(oo)n contains two 2D LiDAR scanners with uniaxial gimbal mechanism, improving self-localization robustness on a slope. The gimbal mechanism adjusts the angle of the LiDAR scanner, preventing erroneous ground detection. We evaluate the navigation performance of Navit(oo)n in the Nakanoshima and its Extra Challenges

Logical design of oral glucose ingestion pattern minimizing blood glucose in humans

Excessive increase in blood glucose level after eating increases the risk of macroangiopathy, and a method for not increasing the postprandial blood glucose level is desired. However, a logical design method of the dietary ingestion pattern controlling the postprandial blood glucose level has not yet been established. We constructed a mathematical model of blood glucose control by oral glucose ingestion in three healthy human subjects, and predicted that intermittent ingestion 30 min apart was the optimal glucose ingestion patterns that minimized the peak value of blood glucose level. We confirmed with subjects that this intermittent pattern consistently decreased the peak value of blood glucose level. We also predicted insulin minimization pattern, and found that the intermittent ingestion 30 min apart was optimal, which is similar to that of glucose minimization pattern. Taken together, these results suggest that the glucose minimization is achieved by suppressing the peak value of insulin concentration, rather than by enhancing insulin concentration. This approach could be applied to design optimal dietary ingestion patterns

A Substellar Companion to Pleiades HII 3441

We find a new substellar companion to the Pleiades member star, Pleiades HII 3441, using the Subaru telescope with adaptive optics. The discovery is made as part of the high-contrast imaging survey to search for planetary-mass and substellar companions in the Pleiades and young moving groups. The companion has a projected separation of 0".49 +/- 0".02 (66 +/- 2 AU) and a mass of 68 +/- 5 M_J based on three observations in the J-, H-, and K_S-band. The spectral type is estimated to be M7 (~2700 K), and thus no methane absorption is detected in the H band. Our Pleiades observations result in the detection of two substellar companions including one previously reported among 20 observed Pleiades stars, and indicate that the fraction of substellar companions in the Pleiades is about 10.0 +26.1/-8.8 %. This is consistent with multiplicity studies of both the Pleiades stars and other open clusters.Comment: Main text (14 pages, 4 figures, 4 tables), and Supplementary data (8 pages, 3 tables).
